Current storage systems face difficulties in efficiently moving items and shuttles between different levels of storage facilities. Existing systems often suffer from inefficiencies related to throughput optimization, shuttle availability, and movement between racks.They are not designed for the transport of heavy loads. It is therefore necessary to develop a system that improves the movement of shuttles 30 to a single level and of stored items to streamline operations and increase overall efficiency and capacity in multi-level storage environments. SUMMARY OF THE INVENTION 35 In a first aspect, the invention relates to a vertical lifting mechanism for transporting loads in a multi-level storage system BE2024 / 5955 3 comprising a lifting cage including substantially vertical rail guides, and a lifting cabin including a lower side configured for vertical movement in the lifting cage, the lifting cabin including: a load support platform positioned on, or forming, the lower side of the lifting cabin, and configured to support loads; a cable-parking lifting system 5,configured to move the lifting cabin vertically within the lifting cage; a plurality of guide wheel assemblies configured to move along substantially vertical rail guides and provide longitudinal and transverse stabilization; the lower side of the lifting cabin further comprises a shuttle receiving cell, configured to receive a loaded or unloaded shuttle, in which at least one side of the lifting cabin contains an access opening to facilitate the entry and exit of a shuttle from the shuttle receiving cell, and the vertical lifting mechanism comprises at least one actuable stop, configurable between a stop configuration, adapted to prevent the movement of a shuttle into or out of the shuttle receiving cell, and a retracted configuration, adapted to permit the movement of a shuttle into or out of the shuttle receiving cell. In a second aspect, the invention relates to a method of transporting a shuttle in a multi-level storage system using a vertical lifting mechanism.The method includes the following steps: positioning a shuttle in a shuttle receiving cell location on the lower side of a lift cabin; actuating a cable-parked lift system, operationally connected to the lift cabin, to move the lift cabin vertically; transferring the shuttle from the shuttle receiving cell to a designated level in the multi-level storage system; transferring loads with the shuttle to the designated level.

For example, in the following claims, any of the claimed embodiments may be used in any combination. 5 In this context, the term "shuttle" is defined as an autonomous or semi-autonomous transport device designed to move horizontally within a storage system, capable of transporting loads such as pallets or containers. 10 In this context, the term "shuttle receiving cell" is defined as a designated compartment,integrated into the lower part of the lifting cabin, specially designed to securely hold a shuttle during vertical transport within the lifting cabin. 15 In the present context, the term "lifting cabin" is defined as the platform or enclosure of the vertical lifting mechanism that moves vertically along the lifting cabin, designed to transport loads or shuttles between levels. 20 In the current context, the term "speed limiter" is defined as a device that monitors the speed of the lifting cabin and activates safety measures, such as a braking system or fall arrest system, when a predetermined maximum speed is exceeded. 25 In the present context, the term "load position sensor" is defined as a sensor configured to detect whether a load extends beyond a predefined reference point. In a first aspect, the invention relates to a vertical lifting mechanism according to claim 30. The invention addresses the inefficiencies of vertical load transport in multi-level storage systems.particularly the challenges associated with integrating vertical and horizontal movement mechanisms suitable for heavy loads. Conventional systems often require separate equipment for horizontal transfer of loads, resulting in increased complexity, reduced throughput and risk of misalignment during operations. BE2024 / 5955 7 The invention proposes a vertical lifting mechanism comprising a shuttle receiving cell integrated into the lower part of the lifting carriage, allowing the vertical transport of a shuttle carrying a load inside the lifting carriage. This system is specially designed to handle heavy loads, making it suitable for demanding industrial applications such as automated pallet storage, warehouse logistics, and manufacturing environments where robust handling of heavy loads and high throughput are required. By allowing the vertical transport of shuttles, with or without a load,The invention 10 offers concrete operational advantages that significantly improve the efficiency and adaptability of multi-level storage systems. The shuttle receiving cell allows for the efficient distribution of shuttles between different levels to respond to fluctuations in demand. For example, in a large-scale pallet warehouse, shuttles from low-demand areas 15 can be repositioned to high-demand areas, thus optimizing resource utilization without the need for additional horizontal transport equipment. This capability is particularly useful in facilities handling heavy goods, such as automotive parts or industrial machinery, where efficient reallocation 20 is crucial to maintaining throughput. The invention also allows for transparent multidirectional handling of loads, as a shuttle can retrieve a load, such as a pallet of raw materials or finished products, from a storage aisle.enter the lifting cabin and be transported directly to another level. Upon arrival, the shuttle can immediately continue its horizontal movement, thus eliminating the need for intermediate load transfers. This not only reduces equipment wear but also ensures safe handling of heavy items, minimizing the risk of misalignment or damage. Furthermore, the ability to vertically transport load-carrying shuttles accelerates order fulfillment in high-volume environments, such as e-commerce distribution centers or food storage facilities. A batch of heavy goods stored on multiple levels can be consolidated more quickly by directly transferring the shuttles from one level to another, which significantly improves processing speed. This approach also improves scalability,Adding new 8-level BE2024 / 5955 storage systems to the existing system does not necessarily require additional horizontal transport mechanisms. The existing shuttles can be repositioned vertically to serve the new levels. The system also improves redundancy and reliability by ensuring that the 5 spare shuttles can be quickly moved to any level if needed. In the event of a malfunction or bottleneck, this flexibility allows operations to continue without delay. The vertical lifting mechanism includes at least one actuable stop, configurable between a stop configuration, suitable for preventing the movement of a shuttle in or out of the shuttle receiving cell, and a retracted configuration, suitable for allowing the movement of the shuttle in or out of the shuttle receiving cell. The actuable stop improves safety by securing the shuttle during vertical transport.This makes the system well-suited to heavy loads and high levels. It prevents any unintentional movement of the shovel that could destabilize the load or cause misalignment. Furthermore, the stop can be easily adapted to different shovel designs, thus offering a simple but effective solution to prevent excessive shovel extension while maintaining compatibility with various configurations. In one embodiment, the shuttle receiving cell is configured to move relative to the lifting cabin to facilitate alignment with the levels of a multi-level storage system, preferably in at least two opposite horizontal directions. This allows for precise alignment with the different levels of the multi-level storage system, reducing alignment errors and ensuring smooth and reliable shuttle entry and exit. In one embodiment, the vertical lifting mechanism further includes a conveying system integrated into the underside of the lifting cabin.said conveying system comprising at least two conveyors, mounted laterally on the underside of the lifting cabin and bordering the shuttle receiving cell. By providing the conveyors laterally to the shuttle receiving cell, the lifting cabin allows the vertical lifting mechanism to be used not only for transporting shuttles, but also for the direct transport of loads. The lateral conveyors allow for the efficient transfer of pallets or other loads into and out of the lifting cabin, while the space between the conveyors remains available to accommodate the shuttle receiving cell. This dual functionality increases the versatility of the vertical lifting mechanism, since it can handle both independent loads and shuttles transporting loads. Furthermore, the conveying system allows for the integration of external handling systems, such as horizontal conveyors,while retaining the ability to transport the shuttles vertically. In applications requiring the handling of various types of loads, such as pallets, bins or containers, this feature improves the efficiency and adaptability of the system.10 In another embodiment, at least one rotating or pivoting element is mounted on the lifting frame at predefined heights, preferably at locations where the lifting frame forms a passage for the entry and exit of the shuttle into the volume of the lifting frame, where the spring mechanism is also mounted on15 the lifting frame,and where the pneumatic or electric actuator is mounted on the hoist cab and is configured to engage with the rotating or pivoting element only when the hoist cab is aligned with the element. The fact that the actuator can only engage with the rotating or pivoting element when the hoist cab is at the correct height in the hoist space improves both safety and operational accuracy. This design ensures that the actuated stop is retracted exclusively when the hoist cab is correctly aligned with the designated entry or exit point of the shuttle, which prevents any unintentional movement of the shuttle and reduces the risk of destabilizing the shuttle or its load. By coordinating the actuation of the stop with the positioning of the hoist cab, this mechanism eliminates the possibility of a Premature retraction or accidental disengagement, thus minimizing misalignment or damage. In one embodiment, the cable-parked lifting system includes a motorized axis 30 configured to drive the vertical movement of the lifting cabin,said motorized shaft comprising a locking system consisting of a set of teeth arranged around the circumference of the motorized shaft, and a lever or safety latch configured to engage with the set of teeth. This locking system enhances safety by ensuring a quick and reliable engagement to prevent any unintentional movement of the lifting cab, such as an uncontrolled descent, in the event of system failure, loss of power, or mechanical malfunction. This locking system is capable of reacting quickly and withstanding significant forces, which is particularly critical when transporting heavy loads. Furthermore, the simplicity of the mechanism allows for easy maintenance and high durability. In another embodiment, the locking system includes a pneumatic or electric actuator 5 configured to engage the safety lever or latch with the set of teeth, and at least one sensor of the locking system,configured to detect the engaged and disengaged positions of the safety lever or latch. Direct configuration detection is highly reliable, with minimal risk of error, and allows the integration of hardwired safety systems, such as emergency stop circuits or interlock systems. These systems, whose probability of failure is inherently low, offer an additional level of safety by ensuring that the elevator mechanism only operates when the correct configuration of the locking system is confirmed. In one embodiment, the locking system is connected to an emergency stop circuit that halts all elevator operations if the safety lever or latch does not engage. This ensures the immediate cessation of movement, thus protecting loads, equipment, and personnel. 20 In one embodiment, the locking system is integrated into an access control system, such as a wired lock,which prevents access to the lifting cab or shaft until the locking mechanism is confirmed. This enhances worker safety during maintenance or operation. 25 In one embodiment, the locking system is linked to a load detection system, which ensures that the safety lever or latch engages automatically when the lifting cab is carrying a load. This prevents unintentional descent in the event of a heavy load and improves the system's reliability. 30 In one embodiment, the locking system is linked to the control system by a latch, which allows vertical movement only when the safety lever or latch is completely disengaged. This minimizes the risk of mechanical damage during operation and ensures safe handling of the lifting cabin and loads. 35 In one embodiment,The locking system is configured to disengage the safety lever or lock from the entire set of teeth by gravity. This BE2024 / 5955 11 configuration allows the system to operate efficiently without requiring a constant power supply to maintain the disengaged state. The gravity-based mechanism reduces design complexity while ensuring fast and reliable disengagement when needed. By defaulting to an inactive state, the system is optimized for applications where the locking mechanism is only required during specific operations, such as controlled shutdowns or emergency scenarios. In the event of a power failure, the gravity-based mechanism allows the system to automatically return to the disengaged configuration, preventing the locking system from remaining locked. in an engaged state and interfere with normal operation of the elevator.10 This design is particularly advantageous for heavy-duty applications, as it balances simplicity, energy efficiency and responsiveness. In one embodiment,Each cable of the cable lifting system has an end anchored to an anchor point, said anchor point supporting the weight of the lifting carriage and a potential load, and the cable lifting system further includes a slack detection system comprising a spring-loaded end integrated into each anchor point and, for each spring-loaded end, at least one slack detection sensor configured to detect an extension of the corresponding spring-loaded end. This slack detection system has several advantages that make it well suited to the applications of the present invention. By detecting the extension of the spring-loaded ends, the system can reliably identify any slack in the cables, which is essential to ensure the safety of the operations. Loose cables can indicate problems such as uneven load, a sudden drop in voltage due to load changes, or potential cable deterioration. Early detection of the problem allows the system to take corrective action.such as stopping operations or redistribution of the load, before other complications arise. 30 The integration of spring-mounted ends ensures a direct and responsive method for measuring cable tension variations. This design is particularly effective for the heavy-duty applications envisaged for the invention, such as the transport of heavy loads at high levels, because it ensures that the system maintains stable and balanced operation, even under 35 dynamic load conditions. In addition, the slack detection sensors improve system reliability by providing continuous monitoring. This function is particularly useful in high-capacity environments where the BE2024 / 5955 12 lifting cabin may frequently handle heavy loads, as it minimizes the risk of accidents caused by cable failures. The system capacity Immediately detecting and responding to release conditions reduces downtime and maintenance costs.ensuring constant and safe operation in multi-level storage and logistics facilities.5 In one embodiment, the vertical lifting system comprises a speed limiter, a tensioner, and a follower cable, in which said follower cable is connected to the lifting cabin and extends between two external points along the lifting cage, and engages at one external point with the speed limiter and at another external point10 with the tensioner. This configuration enhances safety by providing a reliable mechanism for detecting and responding to excessive speeds of the lifting cabin. The follower cable ensures constant communication between the lifting cabin and the speed limiter, which allows the system to quickly activate the braking mechanisms in case of overspeed. The tensioner maintains the tension15 The correct cable tracking ensures precise and consistent operation without misalignment. This design is particularly effective for heavy-duty applications, as it prevents uncontrolled descent of the livestock cabin.protecting the loads and equipment. The simplicity and reliability of the system make it well suited to high-capacity and multi-level storage environments. In one embodiment, the vertical lifting system includes a fall arrest system mounted on the lifting car and comprising at least two mechanical engagement elements adapted to engage with the lifting mechanism in order to stop the movement of the lifting car, said mechanical engagement elements preferably being mechanically synchronized. This fall arrest system offers increased safety by providing an immediate and effective braking mechanism to stop the lifting car in the event of a failure or overspeed exceeding a predetermined value. Unlike an overspeed regulator, which generally depends on the movement of the elevator and associated control systems to activate, the mechanical engagement elements interact directly with the lifting mechanism.offering an integrated safety response independent of external power supply or control signals. This makes the fall arrest system particularly reliable in scenarios involving power loss or system malfunctions. BE2024 / 5955 13 In one embodiment, the fall arrest system comprises mechanically engaged ratchets that lock into notches or slots on the lifting cage when triggered. This configuration ensures robust and immediate engagement, guaranteeing high reliability, particularly under heavy load conditions. 5 In one embodiment, the fall arrest system uses a step-based engagement system, where steps are deployed between the lifting cab and the cage to create friction and stop the cage's movement in case of overspeed. This design allows for gentle deceleration, reducing the 10 risk of sudden shocks to the load and the lifting system. In one case,The fall arrest system includes electromagnetically actuated hooks that engage in the grooves of the lifting lanyard when overspeed is detected. This approach allows for precise and rapid activation15 while also enabling resettable and reproducible operation. In one case, the fall arrest system includes a spring-loaded clamping mechanism that applies friction to the lifting lanyard when overspeed is detected. This mechanism operates independently of an external power supply20, which ensures reliable performance even in the event of a power outage. In one embodiment, the fall arrest system uses a rack and pinion engagement design, where a pinion mounted on the hoist cab engages with a stationary rack on the hoist during overspeed. This allows for controlled engagement with minimal component wear, which is ideal for high-frequency operations. In one embodiment,The fall arrest system includes a hydraulic buffer system composed of hydraulic cylinders that absorb the kinetic energy of the descending lifting cab and progressively stop its movement. This design reduces impact forces, protecting both the lifting cab and the load against sudden stops. 35 In another scenario, the speed regulator is operationally linked to the fall arrest system and allows the mechanical engagement elements to be activated when a predetermined descent speed of the BE2024 / 5955 14 lifting cabin is exceeded. This integration enhances safety by combining the precise speed control capabilities of the speed limiter with the immediate and robust braking action of the fall arrest system. When the lifting cabin exceeds the predetermined speed, the speed limiter triggers the mechanical engagement elements, firmly stopping the cabin to prevent an uncontrolled descent and protect the load, equipment, and personnel. The operational connection ensures a rapid and reliable response.relying on the precise detection of overspeed conditions by the regulator and the mechanical engagement of the fall arrest system for immediate braking. This integrated safety design is particularly suited to heavy-duty applications, offering constant and reliable operation under demanding conditions. In one embodiment, the vertical lifting system includes at least one load position sensor, mounted on an outer edge of the lifting cabin and configured to detect if a load extends beyond a reference point, said load position sensor preferably being a photoelectric sensor. This configuration improves the safety and efficiency of operations by ensuring that loads are correctly positioned in the lifting cab before the start of vertical movement. Detecting if a load exceeds the reference point prevents interference with the lifting cab or other structural components, thus reducing the risk of damage to the load, the lifting system, or surrounding equipment. Furthermore,It ensures the elasticity of the load or shuttle and prevents any misalignment, which guarantees that the transfer of the shuttle or load is always carried out efficiently and without error. 25 In a second aspect, the invention relates to a method of transporting a shuttle within a multi-level storage system using a vertical lifting mechanism according to claim 13. By automating the vertical transport of the shuttles, the method eliminates the need for personnel to manually handle the shuttles or loads at elevated levels. This not only reduces physical labor but also simplifies maintenance operations. The shuttles can be brought back to ground level using the lifting mechanism for inspection or repair, thus avoiding the need for personnel to climb to heights or use less automated and more labor-intensive methods to retrieve the shuttles. Personnel safety and efficiency are thereby enhanced, minimizing downtime related to shuttle maintenance. BE2024 / 5955 15 Furthermore,The method optimizes resource utilization by reducing reliance on additional equipment such as forklifts or cranes to move shuttles from one level to another. This streamlined process reduces operational complexity and maintenance requirements for auxiliary equipment, allowing staff to focus on higher-value tasks and improving overall system efficiency. All of these benefits result in a safer, more efficient, and more cost-effective storage system. 10 In one embodiment, the method includes the steps of configuring at least one actuable stop between a stop configuration that prevents movement of the shuttle into or out of the shuttle receiving cell, and a retracted configuration that allows the shuttle to move into or out of the shuttle receiving cell. 15 In one embodiment, the cable-operated lifting system is actuated by a motorized shaft comprising a set of teeth around its circumference,The method includes the following steps: detecting, using a sensor, whether a lever or safety latch is engaged in the teeth of the motorized shaft; based on the detection, blocking or opening an entrance to the lifting cabin. Blocking or opening the entrance to the lifting cabin based on the detection of the engagement of a lever or safety latch ensures increased safety and operational reliability. It prevents unauthorized or dangerous access, protects personnel against accidents caused by unintentional movement of the lifting cabin, and maintains load stability during operations. By automating safety protocols, the system reduces human error, streamlines processes, and ensures compliance with safety standards. In addition, they simplify maintenance by clearly indicating when access is safe, while contributing to the overall reliability and efficiency of the vertical lifting system. The invention is also described by the following nonlimiting examples,which illustrate the invention and are not intended to limit the scope of the invention and shall not be interpreted as such. 35 EXAMPLES AND / OR DESCRIPTION OF FIGURES BE2024 / 5955 16 Figure 1 shows a side view of a vertical lifting mechanism, comprising a lifting cabin (1) inside a lifting cage (2). The vertical movement of the lifting cabin (1) is driven by a lifting mechanism (4), located at the bottom of the lifting cage (2), by means of cables (8), guided by sheaths (7), anchored at one end to the lifting mechanism (4) and at the other end 5 anchored at the top of the lifting cage (2) to a demotion detection system (6). The lifting lanyard includes actuable stops (5) at different levels along the height of the lifting lanyard (2), blocking entry and exit from the lifting lanyard (2). The lifting cabin (1) is illustrated more clearly in Figure 2. The lower part of the lifting cabin (1) includes a shuttle receiving cell (3), configured to contain a shuttle during vertical transport.and two conveyors (11) positioned laterally relative to the receiving cell of the shuttle (3). The upper part of the lifting cabin (1) is equipped with an anti-fall system (10) which stops the vertical movement of the lifting cabin (1) when the speed exceeds a predetermined limit. This anti-fall system (10) includes two mechanical clutches (12) located on opposite sides of the lifting carriage (1). These mechanical clutches are coupled to a mechanical coupling (13) and engage in the lifting carriage (2) to stop the vertical movement of the lifting cabin (1), as more clearly shown in Figure 3. The actionable stops (5) are more clearly illustrated in Figure 4, which presents an enlarged view of window B as illustrated in Figure 1 and Figure 5.which presents a top view of the lifting cabin (1) inside the lifting 25 bay (2). The lifting cabin (1) includes two actuators (15) which can engage with the two actuated stops (5) at the actuation point (17) when the lifting cabin (1) has aligned itself to the correct level. This causes the actuated stops (5) to rotate to a retracted configuration. The actuated stop is powered by two springs (14), which rotate the actuated stops (5) to a stop configuration, extended upwards, when no actuator (15) is engaged. The actuators (15) can also be positioned on the lifting platform (2), with the actuated stops (15). Alternatively, the actuated stops (5) and the springs (14) can also be positioned on the lifting cab (1), with the actuators (15). BE2024 / 5955 17 The models illustrated in Figures 1, 4 and 5 show two actuated stops at each level, but this number may be greater or less.depending on the type of shuttle or the type of load. The shuttle receiving cell (3) is configured to move as indicated by the arrows (16). This allows better alignment with the different levels of the multi-level storage system, allowing a shuttle to easily enter and exit the rearing hut (1). This lifting mechanism (4) is illustrated in more detail in Figure 6, which shows a close-up view of the window as illustrated in Figure 1, and is illustrated in more detail in Figures 7 and 8. The lifting mechanism (4) consists of a cylindrical drum that rotates around its axis. Thanks to this rotation, the cables (8) wind and unwind around the drum, which allows the lifting cabin (1) to be pulled upwards or lowered in a controlled manner. The rotation of the lifting mechanism (4) is driven by the motor (18).which is powered by the electrical panel (17). The lifting mechanism (4) includes a locking system (19) consisting of a set of teeth (20) arranged around the circumference of the lifting mechanism (4) and a latch (21). The latch (21) is designed to move from one configuration to another: an engaged configuration, in which the end of the latch (21) locks into the series of teeth (20), preventing the rotation of the lifting mechanism (4), and a free configuration, in which the latch (21) disengages from the teeth (20), allowing the lifting mechanism (4) to rotate freely. The latch (21) can be actuated by an actuator (24), one of its configurations being obtainable by the force of gravity. Furthermore, the latch (21) includes a base (23) which extends towards the base and is designed to interact with a safety detector (22). This safety detector (22) monitors the configuration of the latch (21) and, depending on its detection,Access to the lifting cabin may be restricted or critical functions of the vertical lifting mechanism may be deactivated to ensure safe operation. 35 The vertical lifting mechanism may include a slack detection system (6), as illustrated in Figure 9, which shows an enlarged illustration of window C in Figure 1. The slack detection system (6) is integrated into an anchor point (25) of the cables (8), which are mounted on the upper part of the lifting frame (2). A slack detector (26) includes a spring, connected to the anchor points (25) and supporting at least part of the weight of the lifting cabin (1) and a potential load carried by the lifting cabin (1). In addition, the slack detector (26) includes a sensor configured to measure the extension of the spring, which allows the detection of slack between the lifting cabin (1) and a cable. (8). In the embodiment illustrated in Figure 1,the soft detection system(6) is mounted on the upper part of the lifting cabin(2). The vertical lifting mechanism may include sensors for detecting incorrect positioning of loads transported by the lifting cabin (1). These sensors may be mounted on any side defining an entrance or exit of the lifting cabin (1). Figure 10 illustrates an embodiment in which two sensors (27) are placed on two opposite edges of the upper part of the lifting cabin (1). These sensors are oriented downwards. Figure 1115 illustrates an embodiment in which two sensors (28) are positioned on opposite edges of one side of the lifting cabin (1), the sensors (28) being oriented substantially outwards from the plane of the side of the lifting cabin (1). The sensors (27, 28) can be photoelectric cells, ultrasonic sensors, or laser sensors. The present invention is by no means limited to the embodiments described in the examples and / or illustrated in the figures. On the contrary,The methods according to the present invention can be carried out in many different ways without departing from the scope of the invention. 25 BE2024 / 5955 19 CLAIMS 1.
