A manual chain hoist, also known as a chain block is a hand operated hoist that is easy to use and portable. Manual chain hoists are widely used in various industries for their effectiveness in situations where power is not available.
Red Rooster Lifting’s manual hoists and trolleys are available with lifting capacities of from 320kg to 60 tonne.
Some key features and aspects of a manual chain hoist include:
Load Chain: The load chain is a crucial component of the hoist and is designed to withstand heavy loads, providing a reliable means of lifting.
Load Hook: The load hook features a safety latch and a large internal diameter allowing sufficient space for slings.
Hand Chain: The hand chain is used to manually operate the hoist. Pulling the hand chain in one direction lifts the load, while pulling it in the opposite direction lowers the load.
Gear Mechanism: Manual chain hoists incorporate fine toothed gearing, which creates millimetre-precise lifting movements and low manual operating force. The gear wheels and the load pinion are forged, machined and heat treated ensuring maximum resistance and material strength.
Brake System: Manual chain hoists are equipped with a secure and reliable brake mechanism that engages automatically when the operator stops pulling the hand chain. This brake ensures that the load remains in the desired position and prevents it from lowering uncontrollably.
Housing and Frame: The hoist's internal components are housed in an impact-resistant, double-walled casing that protects against deformation and damage, designed to be rugged and withstand the rigors of industrial use.
Capacity and Lift Height: Manual chain hoists come in various capacities, ranging from 250 kg to 50 tonnes. The lift height refers to the maximum vertical distance the load can be raised.
Overload Protection: Some manual chain hoists are equipped with overload protection features to prevent damage to the hoist in case the load exceeds its rated capacity.
