Chain Block
Manual chain block specification:
Gear case and hand wheel cover resistant to external shocks:
Both sides of the hoist are covered with a thick steel gear case, and with a strengthened wheel cover. They have an ideal shape and rigidity to maintain bearing aligment and withstand external shock.
Double enclosure to keep out rainwater and dust
The braking mechanism, which makes up heart of the hoist, is enclosed in a double cover: the wheel and the brake covers. These protective covers not only keep out weather elements but also help to prevent mud and dust from entering internal mechanisms. Hand chain guide attached to the wheel cover provides durability and smooth operation of a hand chain on a hand chain wheel.
Double pawl spring mechanism to further increase of sureness:
In case one of the pawl spring is damaged, the other still maintains its functions. This mechanism further increases sureness.
Sure and reliable mechanical brake
The dry type asbestos-free mechanical brake ensures strong brake performance. Hooks for easy work: specially heat treated top and bottom hooks have enough strength and toughness for hard job. The design of the bottom hook, with relatively large dimensions, makes it easy to stabilize a load in proper position.
Beating mechanism to increase mechanical efficiency:
Use of ball and needle bearings remarkably increases mechanical efficiency and produces high output power with minimum manual input. Load chain gude mechanism: chain guide mechanism in flanged load sheave and guede roller facilitate smooth movement of the load chain.
