Introduction and scope of electric chain hoist

The weight of the electric chain hoist is generally 0.1-60 tons, and the lifting height is 3~120 meters. The characteristics of the electric chain hoist: advanced performance structure, small size, light weight, reliable performance, convenient operation, wide application range, lifting Heavy objects, loading and unloading work, maintenance equipment, and lifting of goods are very convenient. It can also be installed on suspended I-beams, curved tracks, jib crane guides and fixed lifting points to lift heavy objects.

Structural features

Electric chain hoist structure features: electric hoist product structure: the body is made of high-strength tensile shell or die-cast aluminum shell, precision manufacturing by thin-wall extrusion molding process, small size, light weight and high strength. The standard electric chain hoist has a separate gearbox system, a two-stage coaxial transmission gear mechanism in the sealed gearbox, and a long-life oil bath lubrication system. The electric hoist powder metallurgy clutch is used as an overload protection device, and the brake is braked by a disc type DC electromagnetic field, and the braking torque is large, stable, rapid, and low in noise.

Scope of application

The electric chain hoist has a wide range of applications. It is mainly used in various factories, warehouses, wind power generation, logistics, docks, construction and other industries. It can be used for lifting or loading and unloading goods. It can also be used to lift heavy objects for convenient work or repair. machine. The electric chain hoist is operated by the operator on the ground with a button, and can also be operated in the control room or wired (wireless) remote control. The electric chain hoist can be used for fixed suspension, and can also be used with electric monorail trolleys and hand-push/hand-pull monorail trolleys. Tonnage of electric chain hoist: 0.1T 0.25T 0.5T 1T 2T 3T 5T 10T 20T 25T 30T 50T 60T Electric chain hoist installation: hoist single beam, bridge crane, gantry crane, suspension crane. It can also be used for hoisting. Therefore, electric hoist is one of the commonly used lifting equipment in factories, mines, ports, warehouses, goods yards, shops, etc., and it is to improve labor efficiency. The necessary machinery to improve working conditions.

Product component performance and technical requirements

The standard electric chain hoist uses a high-performance lifting motor with a 30-minute class and Class B insulation.

Lifting chain

The electric chain hoist lifting chain adopts Φ7.1mm and Φ11.2mm class 80 surface hardening lifting chain to ensure its safety and durability. The strong hardening surface of the lifting chain prevents product breakage and softening of the core material, thus maintaining high performance of the lifting chain for a long time. The chains of the electric chain hoist are made of low-carbon alloy steel, which makes the chain more tough and more durable, ensuring safety during work. The chain of electric hoist can also be customized according to the requirements of customers, so that you can use it more conveniently and worry-free. The chain of imported electric hoist is equipped with chain bags, which makes the electric hoist look clean and tidy. The chain bag is also equipped with anti-rust oil, so the chain is not easy to rust, thus extending the service life of the electric hoist.

Double brake system

Two complete and independent brake systems not only reduce the possibility of brake failure, but also enhance the safety of the brakes and facilitate heat dissipation.

1. Electromagnetic brakes, the new brake system reacts quickly and provides positive braking force. The use of non-asbestos brake linings greatly extends the maintenance cycle. The brake system was tested more than 22,500 times.

2. Mechanical brakes, very reliable mechanical brakes and electromagnetic brakes coordinate with each other to stop the machine from rotating at any time.

Gear shift

Standard chain electric hoists generally use helical gears to provide reliability and extend life by minimizing gear occlusion and vibration. The special design of the gears enhances the durability of the gears, and the gears are made of alloy steel and are subjected to professional fine heat treatment for maximum strength.

Oil bath lubrication

The gearbox uses a MODE oil bath lubrication system. Lubricating the gear system with an oil bath provides coolant for the mechanical brakes.

Relay (reverse protection)

The relay protects the hoist from damage due to incorrect connection (reverse connection) of the power cord. The convenient maintenance of the steel structure of the electric chain hoist simplifies the maintenance and replacement of parts, which is a great advantage of the electric chain hoist.

Lifting level

The level of lifting is essential for completing a rigorous work cycle and is also a requirement for industrial production. Standard chain electric hoist for 40% ED grades for almost all lifting industrial applications

Overload and under load automatic protection

Use the limit switch to eliminate damage to the hoist caused by overload and under load. Button control handles, light weight button controls are rain resistant and responsive. Anti-wear load wheel, the load wheel is made of alloy steel and professionally heat treated to resist wear and smooth fit with the chain. The new chain design guide provides guidance for the smooth insertion of the chain into the sheave. Low operating voltage of the operating handle The standard operating voltage of the electric chain hoist is 24V-36V low voltage control. The low voltage can effectively protect the operator from electric shock. (The operating handle voltage control at 24V-36V is also a mandatory requirement of the AQSIQ for special lifting equipment.)

Lifting height to the limit

The tight structure of the electric chain hoist can reach the lifting height.

Operation mode

The working mode of the electric chain hoist is divided into single speed or double speed lifting, hanging hook or running trolley with manual or electric, two-way or multi-directional operation.

Overload protection

Some high-end electric chain hoists add overload protection for added extra safety. This is a special protection for the operator, the hoist and the load. When the load is greater than the set value, the overload protection is automatically activated and the hoist lift will automatically stop.

Lifting chain

The nickel hardened chain is specially treated by MODE and does not affect the initial chain performance. Nickel hardened chains have excellent performance and are resistant to rust caused by rain, sea water, streams and chemicals.
