JTPB type mining lift winch
It is used for lifting coal, materials, lifting personnel and allocating materials and equipment, etc.
Product features, main applications and scope of application:This product is suitable for lifting coal, materials, lifting personnel and allocating materials and equipment in the shaft or inclined shaft of coal mine, and can also be used for other traction transportation.
Working principle:When starting the main motor, the rotor of the motor transmits the power to the high-speed axis of the reducer through the elastic coupling, and then transmits the power to the principal axis device through the driving and slowing down of the reducer through the gear coupling, if the steering of the motor is constantly changed, the reel can be twined or the steel wire rope can be loosened, so that the lifting container can make the periodic movement of up and down in the wellbore.
Representation of product model:The model representation method of lifting winch should accord with the provisions of MT/T 154.8-1996.
The diameter of the reel is 1.2 m, and the width is 1.2 m. The product model of the single reel disc sluice mining lifting winch which adopts non-explosion resistance speed control is: JTP-1.2 × 1.2.
