Description

Technical Field

[0001] This utility model relates to the field of crane technology, specifically a compact remote control for truck-mounted cranes. Background Technology

[0002] Truck-mounted cranes are widely used in modern engineering lifting operations, and their ease of operation and safety directly affect work efficiency and personnel safety. Currently, most crane remote controls on the market are single-function designs. Controlling different movements of the crane, outriggers, jib, etc., often requires multiple remote controls or external control boxes, resulting in bulky equipment, inconvenient portability, and complex operation. Furthermore, traditional remote control displays have limited functionality and cannot display multiple crane operating parameters in real time. This makes it difficult for operators to fully grasp the equipment status under complex working conditions, posing a risk of misoperation.

[0003] Therefore, there is an urgent need to develop a highly integrated, compact, and fully functional remote control. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a compact and fully functional remote control for a truck-mounted crane. By integrating multiple joysticks, multi-function buttons and a display screen, it can realize centralized control and real-time status display of all movements of the crane, boom, outriggers and other components.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a compact remote controller for a truck-mounted crane, comprising a housing, handles mounted on both sides of the housing, a control circuit board installed inside, and a panel on the surface, the panel being provided with: a display screen for real-time display of the crane's operating parameters; a rocker area with multiple rockers, each rocker controlling the movement of a corresponding mechanism of the crane by pushing and pulling up and down; a switch area including multiple mode selection switches and multiple function switches, respectively composed of a three-position self-resetting toggle switch, a three-position self-locking selection switch, a two-position self-resetting toggle switch, a two-position self-locking toggle switch, a potentiometer, a self-resetting button, and an emergency stop button; and an indicator light area with multiple load indicator lights.

[0006] Further technical solutions include: The display screen can be a color or monochrome display screen, and different display content and interface layout can be configured according to the model.

[0007] The switch area includes: an engine start / stop function switch consisting of a three-position self-resetting toggle switch; a light function switch consisting of a two-position self-locking toggle switch; a radiator function switch consisting of a two-position self-locking toggle switch; a mode selection switch consisting of a three-position self-locking selector switch for switching between boom control mode, crane control mode, and outrigger control mode; a mode selection switch consisting of a two-position self-locking toggle switch for switching between outrigger vertical mode and outrigger horizontal mode; a mode selection switch consisting of a two-position self-locking toggle switch for switching between winch control mode and counterweight control mode; a regeneration valve function switch consisting of a two-position self-resetting toggle switch; a throttle control knob consisting of a potentiometer; an operating speed adjustment function switch consisting of a three-position self-resetting toggle switch; an emergency stop button; and a horn function switch consisting of a self-resetting button.

[0008] The rocker area has 6 rockers, each corresponding to a different mechanism action in a different working mode, including rotation, luffing, telescopic, outrigger extension and retraction, boom action, winch and counterweight control.

[0009] The three-position self-locking selector switch in the switch area switches between boom mode, crane mode, and outrigger mode, and then works in conjunction with the six rockers to perform function reuse, thereby controlling the working modes of the crane, boom, outrigger, winch, and counterweight.

[0010] The indicator light area includes five load indicator lights, which show the percentage of the crane's current load away from full load by the number of lit indicators. Preferably, the indicator light area has five LED indicators, corresponding to 60%, 70%, 80%, 90%, and 100% load states, with colors of green, green, green, yellow, and red, respectively.

[0011] Next to the display screen are multiple screen switching buttons for switching between different function pages on the display screen, including standard crane page, outrigger page, counterweight page, running time page, anti-collision page, lifting amplitude table page, boom page, etc.

[0012] On the panel, function indicator labels are affixed to both sides of the display screen and above the joystick, and function indicator icons are printed next to each mode selection switch and function switch.

[0013] Compared with existing technologies, the advantages of this compact remote controller for truck-mounted cranes are: 1. Compact structure and high integration: By integrating six joysticks and numerous function switches required to control all movements of the crane, boom, outriggers, etc. into a single handheld device, the combination of multiple control devices in the traditional solution is replaced by a single compact remote control, which greatly improves the portability of the equipment and the convenience of on-site management. 2. The operation is intelligent and simple, and the function reuse rate is high. By combining the joystick and mode switch, the limited physical joystick can be given different control functions in different working modes. This intelligent reuse mechanism greatly simplifies the operation interface, effectively reduces the learning cost and the risk of misoperation, and makes the control of complex hoisting operations more intuitive and efficient. 3. Significantly improves information visualization. The integrated display screen can display various key operating parameters of the crane in real time in page-by-page format, providing operators with a comprehensive and clear view of the equipment status, and realizing the transformation from relying on experience-based judgment to data-driven, visual, and precise control. 4. Flexible configuration and strong market adaptability: It offers flexible configurations such as color and monochrome displays, which can meet the needs of different users for advanced functions and cost control, ensuring the product's high reliability in terms of security and broad market adaptability.
