The System Design Of 3 Tons Forklift Truck Door Frame
Abstract: According to our current country internal combustion performance of the forklift truck door frame, to retrofit design, there are many problems because of the forklift truck working device. Such as: door frame deformation is large, the door frame rail surface indentation and wear and tear, or roller crushed. Pay attention to these problems in the design. To design and calculate the fork frame of the forklift, in order to improve the stability of the forklift frame, enhance the service life and reliability,understand the structural performance of forklift gantry and the hoisting part from the design, and provide the basic data and drawings for the future device.
Key words: Forklift pallet fork; Fork; The door frame; Roller
