The main materials of electric winches (electric hoist equipment) include five categories: body structure, transmission components, braking system, electrical components, and protective components. The specific materials and characteristics are as follows:

1、 Body structure material

High strength tensile shell/die cast aluminum shell

Application scenarios: Light and small equipment such as electric chain hoists and small diamond electric hoists.

Features: Made through thin-walled extrusion molding technology, it achieves the characteristics of small volume, light weight, and high strength, while also having good heat dissipation performance (such as aluminum shell).

Cast steel frame

Application scenario: Load bearing components (such as hooks, brackets).

Characteristics: Able to withstand heavy loads without being easily damaged, ensuring equipment stability.

2、 Transmission component materials

Alloy steel chain

Application scenario: The core lifting medium of the electric chain hoist.

Characteristics: High strength, wear-resistant, suitable for frequent lifting operations.

wire rope

Application scenario: Wire rope electric hoist (such as JM series electric winch).

Characteristics: A 16mm diameter steel wire rope can withstand a tensile force of 16KN and requires regular inspection for broken or twisted wires.

Gears and reducers

Material: High temperature quenched gears with oil bath lubrication structure.

Features: Strong wear resistance, high transmission efficiency, reduced noise and vibration.

3、 Brake system materials

Disc type DC electromagnetic field brake

Application scenarios: Electric chain hoist, Little Diamond electric hoist.

Features: High braking torque, smooth, fast, low noise, ensuring safe stopping.

Disc brake device

Application scenario: The motor and gear parts of the Little Diamond electric hoist.

Features: Dual brake design, achieving instant braking and preventing reverse or over rolling.

4、 Electrical component materials

Explosion-proof motor

Application scenario: Electric dispatch winch (in hazardous environments such as mines).

Features: Supports 380/660V or 660/1140V voltage, with explosion-proof function to prevent internal explosions from igniting the external environment.

Industrial grade squirrel cage induction motor

Application scenario: Little Diamond electric hoist.

Features: Provides stable power and supports high-speed lifting up to 23 meters per minute.

Low voltage electrical control system

Material: DC-24V control circuit, high current card type PCB circuit board.

Features: Safe and reliable, reducing the risk of electric shock.

5、 Protective and auxiliary materials

Powder metallurgy clutch

Application scenario: Overload protection device for electric chain hoist.

Feature: Automatically disconnect power when the load exceeds the rated value to prevent equipment damage.

limit stop

Material: Mechanical or electronic sensors.

Characteristic: Ensure that the hook does not exceed its limit position to avoid malfunctions.

Rope guide

Application scenario: Steel wire rope electric hoist.

Characteristic: Correctly guided to prevent wire rope jumping or entanglement.
