What Is the Purpose of a Construction Hoist Base Spring?
Construction hoist base springs, also known as buffer springs or shock absorbers, are essential components in construction hoists. Their primary purpose is to ensure the safe and stable operation of the hoist by: l Absorbing impact: When the hoist lands, especially with a heavy load, it generates significant impact forces. The base springs act as cushions, absorbing this impact and...
