Hydraulic hand pallet truck

Abstract

The invention provides a hydraulic hand pallet truck according to the defect that in the prior art, a hydraulic hand pallet truck is constant in lifting speed, cannot automatically adjust the lifting speed according to the cargo weight, and is inconvenient to steer and poor in braking performance, and belongs to the technical field of carrying equipment. The hydraulic hand pallet truck can be automatically adjusted to be at a low lifting speed when the cargo is heavy, so that the stability of the lifting process is guaranteed. The hydraulic hand pallet truck can be automatically adjusted to be at a high lifting speed when the cargo is light, so that the carrying efficiency of the pallet truck is guaranteed. Meanwhile, the bottom of a pallet fork of the hydraulic hand pallet truck is improved, and therefore the hydraulic hand pallet truck can conduct transverse movement, has good braking performance, and is prevented from sliding on the slope in the using process.

Description

technical field [0001] The invention belongs to the technical field of handling equipment, and in particular relates to a manual hydraulic transport vehicle. Background technique [0002] The manual hydraulic pallet truck is a small and convenient, flexible, heavy-duty, durable cargo handling tool, commonly known as "ground cow". In addition to the function of consigning goods, the truck has a hydraulic device between the chassis and the wheels to facilitate the lifting and landing of goods. The goods can be moved by dragging them. After arriving at the destination, the chassis is hydraulically lowered, and the goods also land on the ground, and the truck can be easily pulled out. Save the complicated process of manual handling. [0003] During the use of the existing manual hydraulic pallet truck, no matter the weight of the cargo is large or small, the lifting speed of the fork of the manual hydraulic pallet truck is constant. When the cargo is too heavy, if the lifting ...

AI Technical Summary

Problems solved by technology

[0003] During the use of the existing manual hydraulic pallet truck, no matter the weight of the cargo is large or small, the lifting speed of the fork of the manual hydraulic pallet truck is constant. When the cargo is too heavy, if the lifting speed is too fast, it is easy to The lifting process is unstable. At this time, a slow lifting speed is required to keep the cargo stable. When the cargo is light, if the lifting speed is too slow, the handling efficiency will be low; at the same time, the existing manual pallet truck The steering can only be controlled by the rear wheels. When a straight corner is encountered and the corner position space is small, it is inconvenient to turn the manual pallet truck, and it is even difficult to turn and cannot pass.

The existing manual hydraulic pallet trucks basically do not have a braking function, and some manual pallet trucks with a braking function have poor braking performance. In the process of using a manual pallet truck, sometimes it is necessary to go uphill and downhill, and it does not have a braking function. Manual pallet trucks or manual pallet trucks with poor braking performance are very prone to slipping, which may cause some dangerous phenomena.
