What is the difference between single mast and double mast cranes?

Single mast and double mast stacker cranes two different types of stacker cranes used for handling pallets in semi-automatic storage systems. The main difference between them lies in the number of vertical masts or columns that support the crane's lifting mechanism.

1. Single Mast Crane: A single mast crane (also known as a mono-mast crane) has a single vertical mast that supports the lifting mechanism. The mast is typically located at the center or one end of the crane structure. The lifting mechanism, which includes the forks or platform, travels vertically along the mast and can move horizontally along a rail or track system. Single mast cranes are commonly used in smaller storage spaces or where lower lifting heights are required.

2. Double Mast Crane: A double mast crane has two vertical masts that are positioned on either side of the lifting mechanism. The lifting mechanism, similar to the single mast crane, travels vertically along the masts and can move horizontally along a rail or track system. Double mast cranes are generally used for larger storage systems or when higher lifting heights are needed. The dual mast configuration provides additional stability and support, enabling the crane to handle heavier loads and achieve greater heights.

Both single mast and double mast stacker cranes offer similar functionalities and are designed for semi-automatic pallet handling. They can be integrated into automated storage and retrieval systems (AS/RS) to efficiently manage and organize pallets in warehouses or distribution centers. The choice between a single mast and double mast crane depends on the specific requirements of the storage facility, including the size of the space, load capacity, and desired lifting height.
