A detachable body securing mechanism having first and second clamp arms that rotate toward the inside of longitudinal support members of a detachable body to clamp down on the longitudinal support members is disclosed. The first and second clamp arms are rotatably coupled to respective first and second ends of an elongated frame of the securing mechanism. The securing mechanism further includes an actuable piston with a piston body coupled to the first clamp arm and a piston coupled to the second clamp arm. In certain implementations, extension of the piston rotates the first and second clamp arms away from each other and the elongated frame into a clamping configuration for securing the detachable body. Retraction of the piston rotates the first and second clamp arms toward each other and the elongated frame into a retracted configuration for releasing the detachable body.

The present invention relates to a method for determining the mass and the centre of mass of a demountable platform by using a mathematical model, the parameters of which are estimated using an iterative procedure.

A vehicle (2) comprising a working equipment (4) equipped with a movable loading arrangement (5) comprising a first attachment member (7), said vehicle further comprises a sensor system (6) configured to capture environmental data reflecting the environment around the vehicle and to determine, based on said data, image data (8) representing an area at least partly surrounding the vehicle (2). The sensor system (6) is configured to detect and track positions of the first attachment member (7) and a mating second attachment member (9) of the object (20) to load in said image data representation, and, the detected and tracked positions of the first and second attachment members (7, 9) are used to generate a first set of operation instructions for the loading arrangement (5) of the working equipment that decreases the distance between said first and second attachment members such that said attachment members (7, 9) come into position to engage to each other. The control unit 16 is configured to verify that said attachment members (7, 9) are engaged based on the detected and tracked positions from the sensor system (6), and in response to verifying that said attachment members (7, 9) are engaged, enable activation of an object loading mode in which the control system generates a second set of operation instructions for the working equipment to move the loading arrangement (5) so that the object to load is loaded on the vehicle.

Various examples of arrangements and methods are provided for loading and unloading first and second load units carried by a vehicle. A landing device is arranged between a first end of the first load unit and a second end of the second load unit so that a first portion of the landing device is supported to the first end of the first load unit and a second portion of the landing device is supported to the second end of the second load unit. The landing device can move the first end of the first load unit into a lower level than the second end of the second load unit after the first end of the first load unit is moved so that it passes the second end of the second load unit.

The present invention relates to a method for determining the weight of a demountable platform. In the method, a hooklift is used to lift the demountable platform from the ground onto a vehicle, values of a force acting on a main cylinder of the hooklift are determined at predetermined intervals of a physical quantity that varies as a function of the movement of the hooklift, and the weight of the demountable platform is calculated using the determined values of the force. The present invention also relates to a system for determining the weight of a demountable platform.

The present invention relates to a method for determining the length of a demountable platform. In the method, a hooklift is used to lift the demountable platform from the ground onto a vehicle, magnitudes of one or more physical quantities related to a position of the hooklift are determined at a moment when the demountable platform comes into contact with rear rollers of the hooklift, and the length of the demountable platform is calculated based on the determined magnitudes of the one or more physical quantities and the position and orientation information of the hooklift relative to the ground. The present invention also relates to a system for determining the length of a demountable platform.

A system and methods for translating a cable-specific roll-off dumpster onto a vehicle. The system includes a hook lift system having a control arm. The system also includes an assembly that is configured to engage with the control arm. The assembly also includes a frame that is rotatably engaged with a hook lift system of the vehicle. The assembly also includes a tow ring that is rotatably engaged with the frame. The tow ring is adapted to engage a hook of the cable-specific roll-off dumpster. The assembly and the hook lift system translate the cable-specific roll-off dumpster between a loaded position and an unloaded position relative to the vehicle.

A loading arm assembly for a load-handling vehicle has a main arm and an auxiliary arm. The loading arm assembly is configured for unloading and loading ISO containers and for unloading and loading transportation containers having a hook. The loading arm assembly is improved in that a crossbeam having two corner grippers and furthermore, separately therefrom, a telescopic gripping hook is disposed on the auxiliary arm.

Disclosed herein is a hoist apparatus having a base frame, an arm, a hydraulic lift cylinder, and a contact fulcrum attached to the base frame. The arm has a base segment rotatably coupled to the base frame at a first joint, a middle segment rotatably coupled to the base segment at a second joint, and a coupling segment extendably coupled to the middle segment at a second arm joint, the coupling segment comprising a hook at a distal end of the coupling segment. The hydraulic lift cylinder is rotatably coupled at a first end to the base frame and rotatably coupled at a second end to the middle segment. In certain embodiments, the middle segment is contactable with the contact fulcrum during operation of the arm. Various implementations provide for a hoist apparatus that is disposable on a vehicle.

A working equipment assembly arranged to be mounted to a vehicle. The working equipment assembly includes a lift-frame connection arrangement including connection 5 lines adapted to connect control and operating systems to the lift-frame, and an elongated rigid structure configured to guide, protect and at least partly enclose the connection lines over a predetermined length. The rigid structure is pivotably attached to the vehicle by a connection joint at a connection attachment position, and the connection attachment position is close to, and within a predetermined distance from, the arm attachment 10 position, so that the elongated rigid structure is arranged to follow the movement of the movable arm, when the working equipment is operated in the lift-frame mode, and structured to stow at least a part of the connection lines along the longitudinal axis A of the vehicle when the working equipment is operated in the attachment member mode.
