Ease of movement and light weight are key features of enclosed track work station crane systems. In fact, manual work station cranes do the job faster than motorized cranes. Installation is usually more straightforward, and these cranes are also easier to relocate in the future. These systems require a reinforced concrete floor of at least 6 inches. With ceiling mounted systems, supporting steel does not interfere with the handling operation.
Ceiling mounted systems require a building with an adequate overhead structure to hang the crane.
The general rule is less is more. Keep capacities to a minimum. Gorbel Work Station Cranes are designed with an adequate safety factor. If you over-buy capacity, the operator will need to move extra bridge dead weight, which would not be a good ergonomic solution. Keep bridge lengths to a minimum.
