1. Motor: The hoisting motor provides the power needed to lift and lower loads. It is usually an electric motor that generates high torque to handle heavy loads.
2. Gearbox: The motor's rotational motion is transmitted to the hoisting drum through a gearbox. The gearbox helps increase the torque and reduce the speed of the motor, enabling the crane to lift heavy loads at a controlled speed.
3. Hoisting Drum: The hoisting drum is a cylindrical drum around which the wire ropes are wound. It is directly connected to the gearbox and rotates as the motor operates. The drum's size and design determine the amount of Wire Rope it can hold.
4. Wire Ropes:
The wire ropes are wound around the hoisting drum and connected to the hook block. These ropes are made of high-strength steel and have a high load-bearing capacity. Multiple wire ropes are used to distribute the load evenly and ensure stability during lifting operations.
5. Hook Block: The hook block is attached to the lower end of the wire ropes and is responsible for carrying the load. It consists of a pulley system with one or more sheaves, which allows the wire ropes to change direction and support the load securely.
During operation, the motor drives the hoisting drum through the gearbox. As the drum rotates, the wire ropes are wound or unwound, depending on the direction of rotation. This movement raises or lowers the hook block, allowing the crane to lift or lower loads.
The hoisting mechanism is controlled by the crane operator using various controls and switches. Safety features such as limit switches and overload protection systems are also incorporated to prevent accidents and ensure safe lifting operations.
