About NL Series Electric Chain Hoist

Box: the die-casting aluminum box designed through finite element analysis is a modern example of super performance and amazing appearance, feathering with compact structure, light deadweight and wonderful heat dispersion.

Chain wheel: Plug-in connection facilitates the replacement of the whole chain wheel, the non center of gravity design makes the product safer and reliable and the durable material extends the servicing life.

Gear case: the sophisticated gear grinding craft and the self-lubricating no noise design for hard tooth surface makes the motion stable and extends the serving life of gears.

Friction clutch: the setup and adjustment could be easily achieved with the outside adjustable revolving buttons, which not only ensure the safety, but also act as an overload protection.

Motor: German brand, class F Insulation and grade IP55 protection level. It adopts the enclosed DC (Direct Current) Disk Electromagnetic Brake, which can handle brakes more than 1 million times, even during the long time working in the high temperature, its performance could also be guaranteed.

Air plug: Counduit entries are all standard aluminum alloy plug-in plugs and play type, which do not need any other wires.

Limit switch: the inside integrated upper and low limit devices could control the upper and low lifting height effectively, which results in less braking times, long serving life and formation of double safety mechanism with friction clutch.

Chain: top-end with high performance, German brand. The surface of chain has been through the special quality hardening treatment and owns high tolerance to the hostile working environment such as overloading, rain, seawater and chemicals.

Hook group: high-quality German DIN15401 hook group with safety catch sets, compact and rotating in all direction, ensures the safety operation.

The design and manufacture of NL chain hoist conforms to the FEM standard and DIN standard. It combines the 3D object modeling and the finite element analysis technique to further optimize the gear transmission, box structure and dimension of every spare part, in this way, every single component could achieve optimal value.

NL chain hoist adopts Germany technology and all key components are imported with original packaging, such as energy-efficient motors, safety brake, load protection clutch and high-strength wear-resisting chain. The excellent quality makes it match the similar European products. Regarding quality and performance, it always persists in satisfying the clients’ very single requirement uncompromisingly.

2.Type selection principle

1. How is the working conditions?How about the maximum safety lifting load?What is the lifting height?What is the speed?If the load needs careful handle or not?What are the special requirement for the horizontal movement?
