Inspect Crane System Carefully

Brake is an important component of the crane system. It will effect the accuracy and reliability of each mechanism motion directly. So workers should check hoisting and luffing mechanism of the two brake status seriously and watch whether the brake is worn or not. Operators should ensure that the drive brake is flexible, brake bracket is intact, the main spring and an auxiliary spring elastic meets the requirements before working.

While the crane system is working, you should open the cover to check if there is any abnormal noise. The main purpose in checking reducer is ensure there is no oil leakage. People had better focus on the observation of broken wires, wear, corrosion, kink and other conditions while checking the wire rope. Mark on the position that in serious wear and broken wire. So that people could tracking and retesting. At the same time, the steel wire rope is effective in the safety position limiter. The plate number is appropriate.


Checking the pulley before installing. The pulley must be flexible. Otherwise the length of the wire rope and pull force can not automatically adjust through balance wheel. It will increase operation risk degree.

Principle To Manual Chain Hoist Operation

Manual chain hoist is not only own beautiful appearance, but also in good performance. No matter carry or operate it is convenient.

When you use the manual chain hoist, you could not cable stayed or even overload. Other power operation expect human are also not allowed. Before you using the manual chain hoist, you must check it and ensure it is flawless and perfect. Certainly the transmission part and the lifting chain are all in good lubrication. Operators can not do any work or walking under the heavy in order to avoid major accidents. Whether the heavy rise or fall, you had better forced evenly while pulling the chain. Don’t push too hard because the chain may beating or clasp.

Manual chain hoist is widely used in many industries, such as electric power, and building. Manual chain hoist hascompact structure, light weight, small shape size. It is convenient to carry and also in long service life. Manual chain hoist can do many works, such as lifting, traction, drop and calibration.If there is equipped with special device, manual chain hoist can not only do non linear traction operation, but also can easily to choose proper operation position.
