Introduction
Low-headroom Electric Chain Hoists are light and small lifting equipment. Consisted of a motor, transmission mechanism, and chain wheel. Beautiful is out looking, Solid Durable. Inside gears are hot-quenched then increases the wear resistance of the gear and toughness. Adopt international advanced technology, fine workmanship, and gear wheel tight fit.
The lifting height of the Low headroom Electric Chain Hoists can be increased by 1 to 2 meters, making them more flexible and convenient to use in the workplace with a narrow space. Also, with an electric trolley, you can walk up and down the I-beam, usually in four different directions: up, down, left, and right. Electric Chain Hoists are ideal for lifting, transporting, loading, and unloading cargo and heavy loads.

Application Scenarios
The low-headroom electric chain hoist consists of two traveling trolleys and a motor. These compact crane and trolley combos are true space savers! The trolley is specially designed to accommodate the curvature of the chain hoist housing, allowing the hoist to travel higher than most other hoist/trolley configurations. The crane with a trolley can be moved to accommodate a variety of beams, including H-beams, universal beams, prefabricated boxes, es, or I-beams.
Low-headroom chain hoists are suitable for workplaces that have strict requirements on lifting height, and operate at low workshop heights, especially for temporary workshops or places that need to expand the effective lifting space.
Additionally, these low-headroom cranes are ideal for applications with limited headroom and offer efficient, safe, and maintenance-free performance. Widely used in mold, machinery manufacturing, warehousing and logistics, shipbuilding, bridge construction, and other industries.
Low headroom Electric Chain Hoists Components
Lifting motor
Using high performance lifting motor which can last to work 30 minutes with full loading, and has Grade B insulation.
Lifting chain
The chain of the low carbon steel alloy makes the chain more tough, strong, and wear-resisting, ensuring safety during work.
Lifting chain hardened surface can prevent the damage of the core materials and products to soften, thus make lifting chain keep for a long time high performance.
The chain can also according to the request of customer order extended, allows you to use more convenient save worry.
The chain is equipped with a chain bag, make the electric hoist looks clean and tidy, and beautiful. the chain bag contains antirust oil so that chain is not easy to rust, so as to extend the service life of the electric hoist
Double brake system
Two sets of brake systems, not only reduce the brake failure possibility but also increase its safety and benefit for heat radiation.
1. Electromagnetic brake
This new style brake has features of fast and forward direction. Use the asbestos brake lining greatly extended the maintenance cycle. The brake system has been tested by above 22500 times.
2. Mechanical brake
Very reliable mechanical braking and electromagnetic brake are mutual coordination, can stop turning machine at any time.
Variable speed tooth
The standard chain electric hoist mainly uses reliable helical gear, it can prolong service lift by reducing the meshing impact and vibration.
The special design of gear enhances the durability of gear, And gear is made of alloy steel, through professional fine heat treatment obtain the biggest strength.

Control handle with low voltage
The standard low-voltage on chain hoist handle is 24v-36v. Low voltage can effectively protect the operator to prevent shock damage.（24V-36V is compulsive National standard.）

Compared with of electric wire rope hoist
Electric Chain Hoists advantage: fixed lifting spot. Small size, convenient installation, the chain is not easy to snarl.
But relatively, the Electric chain hoists speed is slower and more suitable for precision operation. The point start error does not exceed 1 cm. Such as used in mold factories, wind power stations, car manufacturing, and synchronous ascension in stage performance.
What is headroom?
Headroom is the space from the lifting point to the fully raised hook saddle. (For chain hoists with hitch mounts, the headroom dimension is the distance between the saddle of the top hitch and the saddle of the fully raised bottom hitch.)
