The reducer plays the role of matching the speed and transmitting the torque between the prime mover and the working machine or the actuator, and is widely used in modern machinery. According to the purpose, the reducer can be divided into two categories: general reducer and special reducer. The design, manufacturing and use characteristics of the two are different.

The YZR and YZ series motors are suitable for driving various lifting machinery and metallurgical auxiliary equipment, with high overload capacity and mechanical strength, especially suitable for short-term or intermittent operation, frequent starting, braking, and equipment with vibration and impact.

Electromagnetic brakes consist of permanent magnets that induce currents in a rotating copper disk; the resulting eddy currents interact with the magnetic flux to generate Lorentz forces, which in turn generate braking torque.

Galvanized steel wire ropes with dimensions of 1, 1.5, 2.0, 2.5, 3.0, 3.6, 4.0, 5.0, 6.0, 7.7, and 9.3 are in millimeters, and the specifications are cold galvanized steel wire ropes and hot galvanized steel wire ropes.

QT1B series crane control consoles are mainly used in control circuits with AC 50Hz (60Hz), rated voltage 380V (440V) and below, to control the starting, speed regulation, reversing and braking of motors in crane transport machinery and similar electrical control equipment.

Pulley blocks can be divided into fixed pulleys, movable pulleys, pulley groups, guide pulleys, etc. according to their different functions. In lifting operations, if only fixed pulleys are used, the direction of force can only be changed, and it cannot save effort: although using only moving pulleys can save effort, it cannot change the direction of force.

The I-beam cable pulley series is a conductive form of power supply for the crane trolley. It consists of a walking wheel, a bracket, and a support plate. The flexible cable is fixed on the support plate, and the traction frame is synchronized with the I-beam cable pulley to achieve the purpose of cable power supply.

The crane resistor is suitable for coordinating in circuits with AC 50Hz and low voltage up to 660V, to control the starting and braking of the motor.

Cranes, quay cranes, rail cranes, gantry cranes and other lifting equipment running on rails

The drum group can be divided into two categories according to the number of winding layers of the wire rope: single-layer drum and multi-layer drum.

The explosion-proof air conditioner series has been processed with special explosion-proof technology and can be widely used in flammable and explosive places in Zone 1 and Zone 2. It is widely used in national defense, scientific research, petroleum, chemical industry, medicine, military industry, power plants and other places where there are or may be explosion hazards caused by the mixture of IA, IIB T1~T4 group flammable gas, steam and air. Explosion-proof air conditioners are suitable for places with temperature requirements. Explosion-proof air conditioners are inspected by the National Explosion-proof Electrical Product Quality Supervision and Inspection Center and issued explosion-proof certificates and inspection reports.

The collector is one of the most important components in the sliding wire system.
