Product features:

Unique product structure design, more durable.

Compact structure, and high cost performance.

After forging and heat treatment of the alloy hook, 1:4. hook will not overload safety factor after brittle fracture, only slowly deformation.

High strength ductile cast iron from the wheel, better protect the chain, not easy to wear.

Three - stage gear of high quality gear steel with heat treatment.

On both sides of the lifting wheel with a whole closed type bearing, try running more smoothly, more stable.

Double pawl brake system, greatly improving the safety coefficient of brake.

Both sides are equipped with a nice and compact outer shell, which can protect the gears and brake system.

Super alloy lifting chain, G80 and G100 level can be selected according to the requirements.

Optional with overload protection device.
