• Lifting Capacity: 5 t, 10 t, 20 t, 32 t, and 50 t overhead cranes available; multi-crane or tandem-lift arrangements can be planned for heavy fabrication.

• Single Girder vs Double Girder: Single-girder cranes suit lighter duties and lower headroom; double-girder cranes are recommended for 20 t and above, higher lift heights, and heavy or frequent lifting cycles.

• Duty Class: Standard working classes A3–A5, matched to your daily lifting frequency and service intensity.

• Rail Top Elevation: Hook height and rail-top level are set according to your equipment, product size, and required lifting clearance; we coordinate the column height and runway beam position accordingly.

• Crane Type: Bridge (overhead EOT) crane, gantry crane, or semi-gantry crane can be integrated into the building frame.

Professional tip: Tell us your heaviest lifted piece, how many lifts per day, and the required hook height — these three figures determine whether a single or double girder crane is the right choice, and they drive the column and runway beam design.
