PORTABLE LOAD LIFTING MECHANISM FOR MILITARY VEHICLES

Abstract

The invention relates to a portable load lifting mechanism for use on military vehicles, in particular for lifting loads onto the vehicle. The invention particularly relates to a portable load lifting mechanism comprising a hand winch (20) for lifting the load onto a vehicle, a supporting support post (10) that supports the main weight of the load, and—depending on the application—either a support arm (50) equipped with a dynamometer (51) for measuring weight or for lifting unknown loads, or a portable arm (60) for lifting known loads.

Description

[0001] DESCRIPTION

[0002] PORTABLE LOAD LIFTING MECHANISM FOR MILITARY VEHICLES TECHNICAL FIELD

[0003] The invention pertains to a portable lifting mechanism designed for elevating loads on military vehicles.

[0004] Specifically, the invention involves a portable lifting mechanism that includes a manual crane for raising loads onto a vehicle. It incorporates a carrier pole responsible for bearing the actual weight of the load, along with a dynamometric support arm used for weight measurements or when lifting an unknown-weight unit. Alternatively, it utilizes a portable arm when lifting a unit of known weight.

[0005] KNOWN STATUS OF ART

[0006] Concurrently with technological advancements, significant progress has been made in the evolution of military vehicles. The primary objectives driving these advancements include the pursuit of making military vehicles faster, more comfortable, convenient, and reliable. In the present day, there exists a substantial demand in the field for integrated systems designed to be incorporated into military land vehicles, specifically for lifting loads.

[0007] In the current state of the art, military vehicles employ either body-mounted systems or off-vehicle cranes at the troop level for lifting loads onto the vehicle. The systems integrated onto the vehicle are typically static and lack adaptability for diverse areas or varied equipment usage. Additionally, they occupy valuable space on the vehicle when inactive They are generally suitable for transporting equipment with known weights.

[0008] Consequently, the demand for a novel, cost-effective, comfortable, and practical loadlifting system has arisen to address the challenges posed by current technology and the limitations of existing solutions in the relevant technical field. This necessitated a developmental breakthrough in this domain.

[0009] OBJECTIVE OF INVENTION

[0010] The current invention pertains to a portable load-lifting mechanism affixed to the vehicle body, specifically designed for lifting loads on military vehicles. It has been developed to overcome the aforementioned drawbacks and introduce novel advantages to the pertinent technical domain.

[0011] The primary objective of the invention is to facilitate the seamless installation and efficient lifting of equipment or parts onto military vehicles, ensuring ease of use and operational effectiveness in the desired area.

[0012] Another crucial aim of the invention is its user-friendly installation process and foldable design, enabling effortless stacking either on or inside the vehicle.

[0013] Another significant goal of the invention is the capability to measure weight in the field when required, facilitated by the inclusion of a dynamometer support arm. In instances where lifting equipment of unknown weight is involved, the mechanism verifies whether the safe lifting capacity is exceeded, thereby preventing potential accidents.

[0014] The following figures and their detailed descriptions will make the invention's structural and characteristic features and its advantages easier to understand. Therefore, the assessment should be made by considering the images and their detailed descriptions. FIGURES TO AID IN UNDERSTANDING THE INVENTION

[0037] DETAILED STATEMENT OF INVENTION

[0038] In this comprehensive description, the preferred structural configurations of the loadlifting mechanism are provided solely to enhance comprehension of the subject matter, with no intended restrictive implications.

[0039] Figures 1-9 elucidate the innovative load-lifting mechanism along with its detailed components. In the invention, a skid (80) is affixed to designated areas on the vehicle. Following the connection of the Hook Rope (40) to the Hand crane (20), it is then fastened to the welded foundation carrier pole (10), responsible for bearing the actual load. The roller arm (30) is linked to the carrier pole (10) using the locking pin (70), while the rope with the hook rope (40) is suspended over this roller (31). When a weight measurement is required or when lifting a unit of unknown weight, the support arm (50) with dynamometer (51) is attached. Conversely, if lifting a unit of known weight, the portable arm (60) is connected at one end with pins (70) to the carrier pole (10) and at the other end to the movable roller arm (30). This configuration readies the portable load-lifting mechanism for use. In the invention, the pins (70) serve the dual purpose of connecting and locking the system. In this setup, the dynamometer (51) facilitates weight measurement and is employed for both lifting and weighing units of unknown weight. This feature serves as a preventive measure against lifting weights beyond the mechanism's capacity.

[0040] The circular structure (11) beneath the carrier pole (10) of the assembled portable load-lifting mechanism is maneuvered onto the skid (80) in the designated area. It is then positioned for load lifting by sliding it along the skid (80), as depicted in Figure 4. As depicted in Figures 8 and 9, the hook at the end of the hook rope (40) is attached to the load, and the load is raised onto the vehicle by operating the lever (21) on the hand crane (20). Here, by turning the lever (21), the hook rope (40) is wound around the drum (22). Hence, the process of lifting the load is successfully executed.

[0041] As depicted in Figure 5, the portable load-lifting mechanism is rotated along the axis of the circular structure (11) located at the bottom of the carrier pole (10), allowing the lifted component to be positioned onto the vehicle for stacking. In Figure 7, when the portable lifting mechanism is not in use, the pins (70) are removed, and either the carrier lever (50) or portable lever (60) is detached from the mechanism. The movable roller arm (30) is affixed to the carrier pole (10) through the pin holes designed for its folded closed position. The portable load-lifting mechanism can be folded and stored either inside or outside the vehicle.

[0042] The scope of protection for this application is defined by the claims and is not restricted to the illustrative description provided above. It is evident that a skilled person in the field can establish the novelty of the invention by employing similar embodiments. Furthermore, this embodiment can be applied to other fields with similar purposes within the relevant art. It is therefore obvious that such structures will lack the criterion of innovation and particularly the criterion of exceeding the prior art.
