1,Adopting the deep groove ball bearing of load chain sprocket , pulling is smaller. Equipped with needle bearing for supporting driving shaft it to increase the mechanical advantage.
2. Adopting double pawl brake system and double chain guide roller system, operation is more safe and stable.
3. The top and bottom hook are made of forged high strength alloy, accomplished by heat treatment process. The hooks also have three stretch indicators. However if by any chance the hook is overloaded there is no fear of it breaking, it will simply gradually start straightening out, avoiding any load drop or personal injury.
Precision cast steel latch in bottom hook with embedded design can prevent the bottom hook off effectively.
4. Double-pawl brake system designed for enhanced strength, forget upper, lower hooks with forged steel safety latches, high tensile alloy steel chain.
5. Free-wheeling mechanism for quick chain adjustments.
6. 360 rotating handle of ease of use in confined space.
7. Idling mechanism to allow fast adjustment of load chain.
8. Safety factor 4:1.

1.The lever hoist is made of high strength low carbon alloy steel,
2.High elastic spring with double pawl brake system design featuring stable operation and smooth braking.
It is all significant for improving the security and dependability of the braking system through designing dust cover of braking system.
3.Within auto-clutch,worker can handle the load chain with one hand when there is No-Load.
4.We design sealed guide chain construction to ensure the load chain running safely.
5.The top and bottom hook are made of forged high strength alloy, accomplished by heat treatment process. The hooks also have three stretch indicators. However if by any chance the hook is overloaded there is no fear of it breaking, it will simply gradually start straightening out, avoiding any load drop or personal injury.
Precision cast steel latch in bottom hook with embedded design can prevent the bottom hook off effectively.
6.The stainless steel cap nuts on shell of the hoist protect the screw from various injuries of exposed outdoor for long time and severe chemical environment. This design is also simple to disassemble, easy to maintain
7.Every Huaxin brand hoist individually proof load teat to 1.5WLL with individual serial number.
8.MBL of 400% of WLL.
9.Meeting requirement of EN13157
10.If the handle is locked under a shock load, the lock-releasing mechanism acts to set the handle free to move.
