Hook Mounted Electric Chain Hoist, Fixed Hook Chain hoist

Overview of hook mounted chain hoist

Electric chain hoists can be distinguished according to the type of suspension used to position the hoist above the load. Chain hoist with hook mount has a top hook on the hoist frame or body that enables them to attach temporarily to a trolley, a beam or the structural framework of a building. Besides, a top hook usually has a safety latch to keep the load from swaying or accidentally slipping. Nowadays, chain hoist block has a wide range of application and has become an efficient material handling tool to lift, lower or transport materials and products for its smaller size, lower voice and lighter weight.

Main parts and Components of hook mounted chain hoist

We design and manufacture high-quality electric chain hoist. Chain hoist with hook mount from Yuantai has a compact structure, which is mainly composed of transformer, shell, side magnetic braking device, pendant control, limit switch, hook (including hook safety latch) and so on.

Parts and accessories of hook mounted hoist

• Housing：made of aluminium alloy which is light but hard and can be used in the special work environment with a high heat dissipation rate
• Inverse phase sequence protecting device:the device is used to cut the circuit of the hook mounted hoist in case of wiring error in the power supply.
• Limit Switch: the limit switch device is installed where the weight is lifted on and off make the motor to stop automatically so as to prohibit the chains from exceeding for safety.
• transformer:24 V/36 V/48 V transformer device, this device is used to prohibit unexpected accidents caused by electric leakage and ensure the safety during special environment
• Side magnetic braking device: this device generate magnetic force. It allows instant brake as soon as the electric power is cut off, the braking safety while loading is guaranteed, Electric brake is designed for easy access and simple adjustment. It allows instant brake as soon as the electric power is cut off. Thus the braking safety while loading is guaranteed.
• Chain bag：fixed block is equipped with chain bag, the chain can be automatically stored in the chain bag during operation, in case the chain is stuck and stained with dirt when free falling.
• Motor：the motor with high-performance has light weight and small volume. Its rotating speed can reach 3000r.m.p. High starting torque and sustained rate of electric connection reaches up to 60%, which can meet the demand for high frequency handling.

Application of hook mounted chain hoist

The use of chain hoist blocks increase operational efficiency by dealing with manual lifting and positioning tasks that require intense effort. They uphold physical ergonomics in the workplace. Electric chain hoists have faster operation than other types of hoists. They are cost-efficient and consume less space than conveying systems. When you want to move heavy objects from one site to another in an easier way, electric chain block is a great solution.You are able to finish your lifting work with one push to a button. Electric chain block sare positioned overhead above the load to be lifted. They require access to electrical power source, so they are typically found indoorsand some places where hoists can be plugged into a power supply.They are commonly used in warehouses, machine shops and manufacturing facilities. Most electric hoists are designed to withstand hazardous and high-temperature environments. Safety protocols in operating electric hoists must come first in all environments.

Safety Precautions in Operating Electric Chain Hoists

• Center the load directly underneath the electric chain hoist. Side lifting will cause wear and stress on the chainhoist components.
• Change timely defective, damaged, worn out and corroded components of hook mounted chain hoists like chains hooks, latches, breaks, gears and limit switches. The condition of these important parts must be checked during periodic inspection and maintainedby qualified personnel.
• Remember to keep the chain lubricated all the time.
• Don's try to extend the length of the chains
• Hook the loads carefully to ensure the load is balanced and steady. The safety latch of the hooks must be properly engaged before lifting.
• Never exceed the lifting capacity of the electric chain block. The rated capacityand duty cycle of the hoist, as well as other safety warnings, must be posted and seen by the operators
• People are supposed to keep a safe distance from the suspended load.

Notice:hook chain hoist require an electrical source during operation, unlike manual chain hoists and air hoists. Electricity may cause ignition when the electric hoist is used near flammable objects.
