2JTP Mining Hoisting Winch Product Introduction

1. Product Overview

2JTP series mining hoisting winch is a double-drum winding hoisting equipment, specially designed for inclined tunnels and shafts in coal mines, metal mines and non-metallic mines, 

used for lifting personnel, ore, equipment and other materials.

2. Core structure and design features

1. Spindle device:

Adopts split drum structure (easy to transport and install), the shell material is high-strength low-alloy steel Q345A, and the surface is pressed with spiral rope grooves to reduce wire rope wear;

Adjustable double-row roller bearings are configured at both ends of the spindle to achieve full rolling transmission, and the overall efficiency is ≥90%.

2. Braking system:

Rear disc brake, butterfly spring provides braking force, hydraulic station drive (response time <0.3 seconds), supports secondary braking and electro-hydraulic proportional adjustment;

Equipped with manual gear-type rope adjustment clutch, supports fast clutch and precise rope adjustment.

3. Transmission and control:

Planetary gear reducer or split-flow center drive reducer, smooth transmission and low noise;

Optional PLC+ variable frequency speed regulation system, energy saving of more than 30%, support low-speed heavy-load start-up, and reduce grid impact.

3. Application scenarios and restrictions

Applicable scenarios: underground explosion-proof areas of coal mines (JTPB type), inclined shaft material transportation, and small vertical shaft personnel lifting;

Restrictions:

Non-explosion-proof models are prohibited from being used in flammable and explosive environments;

Inclined shaft loading allows 3 layers of winding, and the number of people is limited to 2 layers; vertical shaft loading is limited to 2 layers, and the number of people is limited to one layer.
