Where the Double‑Girder Hoist Excels
- Heavy duty process cranes: steel, papermills, machining bays & assembly lines.
- Long spans: crab trolley provides stable travel and low wheel loads.
- Precision lifts: VFD hoist with creep speed for accurate positioning.
- Integration ready: overload monitoring, PLC handshakes, sway control.
