Overhead Chain Hoist

Overhead Chain Hoist

 

Overhead chain hoist is a kind of lifting machinery and equipment. It is a light and small lifting equipment. Electric chain hoist hoist has the characteristics of small size, light weight, simple operation, convenient use, safety and durability, etc. It is an ideal tool for lifting goods, loading and unloading workpieces, and maintaining equipment.

 

Electric chain hoists can be installed on suspended I-beams, flexible rails, cantilever crane guide rails and fixed lifting points to transport goods. In low factory buildings and places that are not suitable for erecting bridge cranes, and the selection of wire rope electric hoists is too large In some places, electric chain hoists are more suitable.

 

The electric chain hoist is composed of a motor, a transmission mechanism and a sprocket. The lifting capacity of electric chain hoist is generally 0.1-60 tons, and the lifting height is 4-20 meters. Most electric chain hoists are operated by people on the ground with buttons, and they can also be operated in the control room or wired (wireless) remote control.

 

In addition to being used for fixed suspension, the electric chain hoist is also equipped with electric running trolleys and hand-push and hand-pulled trolleys. Electric chain hoists are widely used in all walks of life in docks, factories, warehouses, buildings and assembly line production operations.

 

The Lifting motor

 

The standard overhead chain hoist adopts high-performance hoisting motors that should have the characteristics of 30-minute class and B-class insulation.

lifting chain

 

Overhead chain hoist generally adopts 7.1mm and 11.2mm grade 80 surface-hardened lifting chains to ensure its safety and durability. The hardened surface of the lifting chain is used to prevent product breakage and softening of the core material, which allows the lifting chain to maintain high performance for a long time. The MODE hardened chain adopts advanced technology, and each chain is tested to ensure its toughness and safety.

 

 

Dual brake system

 

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

 

1. Electromagnetic brake

 

The new brake system responds quickly and provides positive stopping power. The use of non-asbestos brake linings greatly extends maintenance intervals. The brake system has been tested more than 22,500 times.

 

2. Mechanical brake

 

Very reliable mechanical brakes and electromagnetic brakes work together to stop the machine at any time.

 

Gear change

 

Standard electric chain hoists generally use MODE helical gears to provide reliability and prolong life by minimizing gear bite effects and vibration. The special design of the gear reduction for greater durability, and the gears are made of alloy steel with professional fine heat treatment for maximum strength.

 

Oil bath lubrication

 

The gearbox adopts an oil bath lubrication system. The use of an oil bath to lubricate gear systems can also act as coolant for mechanical brakes.

 

Lifting level

 

The lifting level is the most basic to complete the strict work cycle and is also the requirement of industrial production. The standard electric chain hoist is rated at 40% ED to meet almost all lifting industry applications.

 

Overload and underload protection

 

Use limit switches to eliminate damage to the hoist from overloading and underloading.

 

Button control handle

 

Lightweight button controls are rainproof and responsive.

 

Anti-abrasion load sheave sheave

 

The load sheave is made of alloy steel and has undergone professional heat treatment for the purpose of anti-wear and smooth fit with the chain. The new chain design guidelines provide guidance for smoothly embedding chains into sheaves.

 

Operating handle voltage

 

The operating handle voltage of the standard electric chain hoist is 24V-36V low-voltage control, and the low voltage can effectively protect the operator from electric shock. Controlling the voltage of the operating handle at 24V-36V is also a mandatory requirement of the General Administration of Quality Supervision, Inspection and Quarantine for special lifting equipment.

 

Headroom

 

Overhead chain hoist compact structure design can reach the maximum possible lifting height.

reverse protection relay

 

The relay protects the hoist from damage due to misconnection (reverse connection) of the power cord.

 

Easy maintenance

 

The steel structure design of the overhead chain hoist simplifies the maintenance and replacement of parts, which is a great advantage of the electric chain hoist.

 

Way of working

 

The working mode of electric chain hoist is divided into single-speed or double-speed lifting, hanging hook or running trolley with manual or electric, three or single and more options.

 

Overload protection

 

Some high-end electric chain hoists add extra safety, which is a special device for protecting the operator, hoist and load. When the load is greater than the set value, the overload protection is enabled and the hoist will stop automatically.

 

Nickel surface hardening

 

MODE nickel hardened chains are specially treated so as not to affect the original chain performance. Nickel hardened chains offer excellent performance and are resistant to corrosion from rain, sea water, stream water and chemicals.
