Description

Technical Field

[0001] The utility model belongs to the technical field of stackers, in particular to a stacker that is prevented from falling. Background Art

[0002] The stacker has a simple structure, flexible control, good micro-motion, and high explosion-proof safety performance. It is suitable for operations in narrow passages and limited spaces, and is an ideal equipment for loading and unloading pallets in high-bay warehouses and workshops. It can be widely used in industries such as petroleum, chemical, pharmaceutical, textile, military, paint, pigment, coal, and ports, railways, freight yards, warehouses and other places containing explosive mixtures for loading, unloading, stacking and handling operations. It can greatly improve work efficiency, reduce the labor intensity of workers, and win market competition opportunities for enterprises.

[0003] Stackers are classified into the following categories: 1. Manual stackers, which are not equipped with any power device and are completely pushed and pulled by manpower. They have a small turning radius and require a lot of effort to lift. 2. Fully electric stackers, whose lifting device and driving device are both powered by electricity. The driving device is a battery that drives the motor to drive the wheels to rotate to achieve movement in direction and position. The lifting device also uses a motor to drive the hydraulic station to push the hydraulic cylinder to achieve lifting. 3. Semi-electric stackers, semi-electric stackers have no driving device, only a few basic load-bearing wheels and direction wheels. Therefore, the movement of the position of the semi-electric stacker requires manpower to push it, and the lifting aspect is that the motor drives the hydraulic station to push the hydraulic cylinder to lift the goods. Due to its low cost, flexible and convenient use, it is widely used.

[0004] When a forklift is performing an object lifting operation, there is often a risk of the object shifting and falling because the center of gravity of the object is unstable. Utility Model Content
