How it works

The closed wire rope with a container hanging in the middle is wound on the drum, when the motor drives the closed wire rope with a container hanging in the middle of the roll is wound on the drum, when the motor drives the roll to lift and lower; Speed regulation is achieved through electric transmission; Disc brakes are braked by hydraulic and electrical control; Through a variety of locations

The instructing system realizes the depth indication of the container; Through the mechanical, electrical and hydraulic combined system composed of various sensors and control elements, the whole machine is monitored and protected; Through computer and network technology, the information transmission inside and outside the elevator is realized.

Technical features:

1. According to the performance parameters of the hoist, it can be equipped with a single brake disc or a double brake disc friction wheel, and the friction liner of the floor-mounted friction hoist is a double rope groove, and is equipped with a rope dialing device, and the well tower type is a single rope groove.

2. Under the condition of no oil, water or special grease, the friction village mat can be made of Nissan GM-3 or GDM-326 high-performance materials, and its friction coefficient is 20.25.

3. The overhead wheel and guide wheel device are eccentricly arranged, and the wheel flange is equipped with polymer wear-resistant material liner to reduce the wear of the wire rope.

4. The rear disc brake of the oil cylinder is adopted, and the electric and hydraulic joint control is adopted, and the hydraulic station is divided into two types: medium pressure and medium and high pressure. The medium-voltage hydraulic station has two modes: constant braking torque, electrical delay and hydraulic delay secondary braking; The medium and high pressure hydraulic station has two forms: constant deceleration and constant braking torque two-stage braking.

It can be equipped with pressure relays, pressure sensors and pressure transmitters.

5. Speed measurement transmission and backup protection, supporting the provision of brake plate deflection monitoring device, wire rope sliding monitoring device, trough device, special tools and other components.

6. There are four kinds of operating tables to choose from, all of which use integrated signal lights, two of which are desktop type, equipped with a new integrated operating handle, one of which is a counter with liquid crystal display, and two are split operating consoles, equipped with digital depth indicators. All have industrial TVs or computers, printing

special countertops for machines.

7. It is equipped with mine hoist network control and remote diagnosis system.

8. WSM-3 new environmentally friendly non-asbestos brake shoe is adopted, and its superior performance ensures the safety of disc brakes.
