High quality 0.5 ton manual chain pully block with G80 chain china supplier

Features of chain hoist (chain block)

• Durability

• Grade 100, corrosive resistant plated load chain is a smaller, more compact link that is 20% stronger than Grade 80 load chain

• Secured with Allen screws and lock nuts, the cast-steel safety latches are more durable than stamped steel latches and will not bend out of compliance with lifting regulations

• Intended for the harshest environments, the heat treated load plates and case hardened corrosive resistant internal parts extend the life of the hoist

• Caged needle bearings support the load sheave to increase efficiency and promote smooth operation

• Impact resistant all steel construction for added durability and protection

• The lightweight design with shorter handle and smaller body are ideal for confined areas and low headroom applications

• Standards

• This china chain hoist/chain block complies with ANSI /  ASME B30.21 and HST-3 standards

• Load tested to 125% of capacity with certificate

 Capacity is the maximum rated load a chain hoist can handle. While manufacturers may indicate they have tested a hoist beyond its limits, operators should never attempt to lift a load heavier than the maximum rated load. Pull force describes the amount of force that needs to be applied to lift a load.
 If a 1/2 ton manual hoist specifies a pull force of 40 lbs., for example, the operator needs to be able to pull a 40 lb. weight in order to lift the maximum 1/2 ton (500 lb.) load. Headroom is the distance from the bottom of the load  hook to the top of the hoist. This is the minimum amount of vertical space needed for the hoist to hang freely and operate correctly. Lift is the maximum vertical distance the load hook can move a load.

 
 Chain Hoists can be attached to structures such as cranes, ceilings, or walls by a variety of methods including hook, trolley, deck, base, wall, and ceiling mounts. They are used in a variety of industries including transportation, construction, manufacturing, mining, plumbing, foundry, and materials handling.
