Hand-operated and rolling device for lifting and moving pallets with lifting effect by wheel camber change

摘要

The present invention relates to a hand-operated device for lifting and moving pallets. The device comprises a framework including a first and a second fork (1, 2) projecting forwardly from the framework, each fork having a top surface (6) adapted to be in contact with the pallet, a handle (7) connected to the framework for applying manual force to the framework, support members (8a-d) connected to the framework for supporting the framework from the ground, and a first leg (3) having an upper end operatively connected to the handle and a lower end connected to the first fork to form a first frame element (10), and a second leg (4) having an upper end operatively connected to the handle and a lower end connected to the second fork to form a second frame element (12). Each of the first and second frame elements is arranged pivotable about an axis in parallel with the longitudinal axis (L₁, L₂) of the respective fork such that the framework is allowed to pivot between a first position for transporting the pallet and a second position for positioning the forks under the pallet, and the forks and support members are designed such that the vertical distance (h₁, h₂) between the highest point of the top surface of the forks and the lowest point of the corresponding support members is shorter in the second position than in the first position, and by that the fork and the support member of each frame element form a lever for lifting and lowering the pallet.
