A well elevating conveyor/elevator is a large mechanical equipment that transports by changing the potential energy, such as mine hoists, dam crossing hoists, etc. Generally speaking, elevators, overhead cranes, hoists, stabilizers, cranes, and hoists can all be called elevators. Elevators generally refer to large mechanical equipment with high power and strong lifting capacity. The transportation process is completed by dragging the flexible steel wire rope and the transported goods up and down through power machinery. Steel wire rope is an important part of lifting machinery, and the main varieties include phosphating coated steel wire rope, galvanized steel wire rope, stainless steel wire rope, smooth steel wire rope, etc.
Manual hoistMainly used for the transfer and addition of solid powder materials. Manual adjustment, easy operation, dust flying and crossing, labor intensity, work efficiency.
Its working principle is mainly composed of chassis, pillars, and manual system. When working, manually feed the material bin to the required level, and then rotate the chassis to connect the feeding material bin for feeding operation. It has two major characteristics: 1. The outer surface of the machine is made of matte stainless steel plate, which has a beautiful appearance. 2. The machine adopts manual operation, which is simple, convenient, stable, and can be automatically locked at any time. At the same time, it can rotate the wheels, adjust the direction, and meet different production needs.
Safety regulations
The hoist is maintained and managed by personnel, and the key to the power switch box is managed by personnel.
The hoist must have a hoist limiter and a travel limiter, and the limiter should enable the pulley to automatically stop before lifting to a distance of 300mm from the drum or pulley. The action is sensitive and reliable, and a trial lifting is conducted.
The hoist should have a high load mark, and the weight should not exceed the limit during lifting and landing.
After power transmission, check safety devices such as winch limiters, travel limiters, interlock switches, etc
Before lifting or landing, the car can only be driven after sounding the alarm bell.
Elevators are strictly prohibited from carrying people up and down.
After the work is completed, the lifting platform of the hoist should land, then cut off the power and close the upper and lower guardrail doors.
Regularly maintain the hygiene of the surrounding environment of the elevator.
Precautions
Drive with no load. So before stopping each time, all the materials in the hopper should be drained before stopping.
Cannot be reversed. Reversing may cause chain derailment, and troubleshooting derailment is very difficult.
Feed evenly. Do not suddenly increase the feeding amount. The feeding amount cannot exceed the conveying capacity of the elevator. Otherwise, it is easy to cause serious accumulation of materials at the bottom, resulting in a "stuck car" accident.
Timely and appropriately replenish lubricating oil.
When the chain and hopper are severely worn or damaged, they should be replaced in a timely manner.
