CHAIN BLOCK, 1,With Dual rachet pawl, Needle bearing, 2,Approved by CE GS, 3,Double guide roller., 4,G80 load chain. - details see: https://www.machineto.com/hsz-cb-1ton-manual-chain-block-heavy-duty-type-10097173

CB Model CHAIN BLOCKspecification:

• Use forged upper&bottom hook.
• Supur strong heat treated G80 Grade load chain black coating.
• Galvanized hand chain.
• Dual guide roller.
• Wet friction discs for longer life.
• Tough gear case reinforced with four ribs and four knock pins.

• Gear Case and Hand Wheel Cover Resistant to External Shocks:

Both sides of thehoistare covered with a thick steel gear case, and with a strengthened

wheel cover. They have an ideal shape and rigidity to maintain bearing alignment and

withstand external shock.

• Double Enclosure to Keep Out Rainwater and Dust:

The braking mechanism, which makes up heart of thehoist, 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 ahand chainon ahand chain wheel.

• Double Pawl Spring Mechanism to Further Increase of Sureness:

In case one of Pawl spring is damaged, the other 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.

• Bearing Mechanism to Increase Mechanical Efficiency:

Use of ball and needle bearings remarkably increases mechanical efficiency and

produces high output power with minimummanualinput.Load Chain Guide Mechanism:

Chain guide mechanism in flanged load sheave and guide roller facilitate smooth

movement of theload chain.

• Highly Accurate and Durable Gears:

• Stopper Prevents Excessive Lowering:

Stopper assembly prevents excessive lowering of a load and also keepsload chain

from exiting if over lowered. When you feel a noticeable increase in pull force to lower

the load, you may realize that you cannot lower the load any further.

• Ultra Strong Load Chain (Nickel plated)

Load chains, the component comprising the heart of thechain hoist, are made of an

exclusively developed, heat treated special steel alloy.
