A hydraulic hoist can be used to load and unload shipping containers.
A hydraulic hoist is equipment used to lift or move heavy or oversized objects. Unlike traditional cranes or elevators, hydraulic winches rely on an oil-based piston mechanism rather than a large motorized operating system. This piston mechanism allows the hydraulic hoist to lift much larger loads with a very small motor compared to similar sized cranes or hoists.
A hydraulic hoist can be used to give auto mechanics access to the underside of vehicles.
Many marinas and shipyards use a hydraulic hoist to move boats in and out of the water. Others rely on these hoists to load and unload cargo and shipping containers from the ship to nearby trucks or storage facilities. Manufacturing and warehousing operations can use a hydraulic hoist to move equipment or assemble and store finished products.
A hydraulic hoist can also be found in mining or excavation operations, where it lifts heavy objects out of the way of workers. These hoists can also be used to lift steel or other structural components on a job site. Some trucks and boats use hydraulic winches for small lifting jobs or even converting a standard truck bed into a dump truck.
Most marinas have a hydraulic winch to get boats out of the water.
These hoists use a small electric motor to move one or more pistons within the device. As the pistons move down, they apply pressure to the oil supply below. Once the oil contracts to its minimum size, it transfers this pressure to the lifting mechanism. When the pistons move in reverse, the hoist can lower or release objects as directed by the machine operator. Most have a standard operator cart, which sits along the base of the support tower.
One of the main advantages of using a hydraulic hoist is the relative distance between the motor and the hoist. With the motor out of the way, the machine can operate much more quietly than a traditional crane or elevator. This makes them ideal for indoor use or for moving theater sets between acts without disturbing the audience. These systems also offer a large volume of lifting force compared to their small motors as well as their overall size.
These hoists are also associated with some potential downsides that buyers should be aware of. Hydraulic hoists do not operate as efficiently as other lifting devices, which can decrease productivity and increase some operating costs. Like all hydraulic based systems, these hoists are susceptible to leaks or broken seals within the oil cavities, which require extensive repair and maintenance work.
