Mobile gantry cranes can be equipped with various types of lifting mechanisms depending on the specific application and lifting requirements. Here are some commonly used lifting mechanisms in mobile gantry cranes:
Electric Chain Hoists: Electric chain hoists are widely used in mobile gantry cranes due to their compact size, lightweight design, and ease of use. They consist of an electric motor-driven chain that lifts and lowers the load. The hoist unit is typically suspended from a trolley that moves along the crossbeam, providing horizontal mobility.
Wire Rope Hoists: Wire rope hoists utilize a steel cable or wire rope wound around a drum to lift and lower the load. They are capable of handling heavier loads compared to electric chain hoists. Wire rope hoists are commonly used in mobile gantry cranes where higher lifting capacities are required.
Manual Chain Hoists: Manual chain hoists, also known as chain blocks or come-alongs, are operated manually by pulling a chain to lift and lower the load. These hoists are suitable for lighter loads and are often used in situations where power is not readily available or as a backup lifting mechanism.
Pneumatic Hoists: Pneumatic hoists, or air hoists, utilize compressed air to power the lifting mechanism. They are commonly used in environments where electrically powered hoists are not suitable due to the risk of sparks or the presence of flammable materials.
Hydraulic Hoists: Hydraulic hoists use hydraulic power to lift and lower the load. They are often used in applications where precise control over lifting speed and positioning is required. Hydraulic hoists can handle heavy loads and are known for their smooth and controlled lifting operation.
It's important to note that the specific lifting mechanism used in a mobile gantry crane will depend on factors such as the required lifting capacity, lifting speed, control requirements, and the environment in which the crane will be used. The choice of lifting mechanism should be made considering the specific needs and safety considerations of the lifting operation.
