Ketttõstukid

Kett-tõstukid, often referred to as chain hoists, are mechanical devices used for lifting and lowering heavy loads. They operate by using a hand chain or electric motor to drive a gear mechanism that pulls a load chain. This load chain is typically made of high-strength steel and is fitted with a hook for attaching to the load. The primary advantage of a kett-tõstuk is its ability to provide significant mechanical advantage, allowing a user to lift loads that would otherwise be impossible to move manually.

Manual kett-tõstukid are operated by pulling a hand chain. One chain is for lifting and lowering the load, while the other is a control chain that drives the internal gears. Electric kett-tõstukid use an electric motor to power the lifting mechanism, offering greater speed and efficiency for frequent or very heavy lifting operations. They are controlled via push buttons or remote controls.

Kett-tõstukid are commonly found in industrial settings, workshops, construction sites, and warehouses. They are used for a variety of tasks, including assembly, maintenance, and material handling. Safety features such as overload protection and braking systems are crucial components of kett-tõstukid to prevent accidents. Regular inspection and maintenance are essential to ensure the safe and reliable operation of these lifting devices. The choice between a manual and electric kett-tõstuk depends on the frequency of use, the weight of the loads, and the available power source.
