Components and functions of chain electric hoist

Lifting chain: The lifting chain of the electric chain hoist adopts 7.1mm and 11.2mm grade 80 surface carbon black to ensure its safety and durability. The strong hardened surface of the lifting chain can prevent product damage and softening of the core material, so that the lifting chain can maintain high performance for a long time.

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. The electromagnetic brake system responds quickly and provides positive braking force. The use of non-asbestos brake linings greatly extends the maintenance cycle. The brake system has been tested more than 22,500 times. 2. The mechanical brake is very reliable. The mechanical brake and the electromagnetic brake are coordinated with each other, and the machine can be stopped at any time.

Commutateur de limite: When the electric chain hoist rises or falls to the limit, the limit switch automatically cuts off the power. The limit switch can effectively prevent the collision of the lifting object with the body.

Transmission gear: Standard electric chain hoists generally use helical gears to provide reliability and extend life by minimizing the impact of gear engagement and vibration. The special design of the gears enhances the durability of the gears, and the gears are made of alloy steel and undergo professional fine heat treatment to obtain maximum strength and wear resistance.

Button control handle: Lightweight button control is rainproof and responsive. The operating handle voltage of the standard electric chain hoist is 24V-36V low voltage control. The low voltage can effectively protect the operator from electric shock. (The control of the operating handle voltage at 24v-36V is also a mandatory requirement for special lifting equipment by the General Administration of Quality Supervision, Inspection and Quarantine.)

The chain of the electric chain hoist is made of low-carbon alloy steel, which makes the chain more tough, stronger and more wear-resistant, ensuring safety during work. The length of the lifting chain can be customized according to the customer's requirements, and it can also be used in the case of large strokes. The chains of electric chain hoists are equipped with a chain bag, which makes the Longsheng brand electric chain hoist look clean and tidy. The chain bag also contains anti-rust oil so that the chain is not easy to rust, thereby extending the use of the electric hoist. life.

Reverse phase protector: The reverse phase protector can protect the hoist or hoist motor from damage due to the wrong connection (reverse connection) of the power cord.

Anti-wear load sheave: The load sheave is made of alloy steel and has been professionally heat-treated to resist wear and smoothly fit the chain. The new chain design guidelines provide guidance for smoothly embedding the chain into the pulley.

Emergency stop switch: This button is used to stop the action of the hoist in an emergency. It is a red, mushroom-shaped button located at the top of the button handle. When the button is pressed, the power of the hoist will be cut off, and the button has an automatic lock function.

Overload protection: Electric chain hoist (optional) adds an overload protection device for extra safety. This is a special protection device for the operator, hoist and load. When the load is greater than the set value, the overload protection is automatically activated, and the hoist hoisting will automatically stop.
