Manual hoists are most often used in rigging, maintenance, construction, automotive, general manufacturing, mining, and oil applications. Their compact design allows them to be used in tight quarters, and in applications where electricity is impractical or is not available. Manual hoists have a simple design that allows for easy inspection, maintenance, and cleaning. The chain is pulled using a hand-over-hand motion, or a handheld lever or ratchet, to turn the gears located inside the hoist and deposit the chain in a chain basket. One chain is used to lift and lower the load and the other chain is used to support the load. Manual hoists can be designed in either a chain or wire rope configuration, and are mainly used for occasional lifts where speed of the lift is not a factor. Wire rope drum occupies more space than a chain hoist.Wire rope may not be as durable as chain in certain instances.The main disadvantages of using a wire rope hoist include: Dominates the market at 10-tons and above.Can be rated to severe duty classifications.The main advantages of using a wire rope hoist include: Wire rope is a popular choice in production environments because it can perform lifts at a faster speed, higher heights, and can also be rated for severe duty classifications- Class D, E, and F cranes. Wire rope hoists can be powered manually, electrically, or pneumatically. Wire rope hoists use wire rope as the lifting medium and perform the lift by wrapping the wire rope cable around a grooved drum. They typically dominate the market at capacities of 10-tons or more. Wire rope hoists offer smooth and quiet operation and can perform lifts at a faster speed than chain hoists. May be problematic at lift heights above 20 feet.The main disadvantages of using a chain hoist include: Capacity up to 25-tons (as standard design).
Manual crane lift portable#
Portable and can tolerate greater levels of abuse.Compact, space-saving design with no drum.Ability to change the height of the lift by changing out the chain.The major benefits of using a chain hoist include: While they’re a reliable and economical option, chain hoists do have a lower capacity and are more commonly found on lighter duty applications under 5-tons. Chain hoists can be powered manually, electrically, or pneumatically. Chain hoists are a popular choice because they’re relatively low maintenance and can be less expensive than a wire rope hoist system. Chain hoists are typically found on lighter-duty applications.Ĭhain hoists use metal chain as the lifting medium and perform the lift by pulling the chain through sprockets and then deposit it into a container. Chain hoists are a portable, economic, and space-saving option that can be powered manually, electrically, or by air.
