This site covers the technical and commercial decisions behind selecting overhead, gantry, and hoisting equipment. It addresses load ratings, structural materials, control systems, and the documentation buyers need to verify a supplier's output.
Readers find practical comparisons of hoist and winch functions, rigging components, and inspection routines. The content focuses on what affects cost, lead time, and long-term maintenance, without vendor promotion.
Frequently asked questions
What is the difference between a trolley hoist and a jib hoist?
A trolley hoist runs on a rail system and moves loads horizontally over a span. A jib hoist is mounted on a rotating arm and typically handles smaller loads in a fixed radius.
How do I determine the required load rating for a crane?
Calculate the maximum load weight, add the weight of the lifting gear, and apply the appropriate safety factor. Check the manufacturer's load chart for specific configurations and boom angles.
What are the key components of a gantry crane?
Gantry cranes consist of two parallel rails, a transverse beam, a trolley, and a hoist. Structural steel and the rail type significantly affect the load capacity and maintenance requirements.
How often should overhead cranes be inspected?
Inspections are typically required daily by operators and at regular intervals by qualified personnel. Frequency depends on the duty cycle, local regulations, and the condition of the equipment.
What factors affect the lead time for custom cranes?
Lead times depend on design complexity, material availability, electrical system specifications, and factory capacity. Standard models often have shorter delivery times than custom-engineered units.
How do I evaluate a crane supplier's reliability?
Review the supplier's track record with similar projects, check their quality control processes, and verify references from current clients. Request sample inspection reports and maintenance records to assess their standards.
