Abstract

An expandable hand-operated carrier fork arm comprises a main arm, expanding arms, equilong rods, damping universal wheels and square sleeves. The equilong rods are hinged to the hinged points of the main arm and the expanding arms, the intersections of the equilong rods are sleeved with the square sleeves, and the damping universal wheels are fixed on the expanding arms. The expandable hand-operated carrier fork arm is simple in structure, the adjustable degree of the stability of a hand-operated carrier is improved, and potential safety hazards can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of logistics machinery, in particular to an expandable fork arm of a manual pallet truck. Background technique [0002] Manual pallet truck is a tool commonly used in factory workshops, supermarkets, and warehouses. It is mainly used to carry various goods or other heavy objects, which can reduce labor intensity and improve labor efficiency. With the improvement of technology, the load capacity of the truck increases, and the volume or weight of the heavy objects to be transported is also increasing. Unexpected fluctuations or sharp turns during the transportation process may easily cause the center of gravity of the goods to be unstable and dump, resulting in safety hazards. . Contents of the invention [0003] The purpose of the patent of the present invention is to provide an expandable fork arm of a manual pallet truck. By installing retractable extension arms on both sides of the fork arm, the purpos...
