Project Case: Chashma Canal Water Gate Lifting Project, Pakistan
Project Introduction
This is a public international tender for water intake renovation in Pakistan. A total of 8 sets 10-ton European-style low-headroom double-girder wire-rope trolley hoists were supplied, including full sets of matched rail tracks and fasteners. The hoists are installed outdoor on top of reinforced concrete dividing walls, for lifting & cleaning trash racks and gates at the bottom of 10-meter-deep intake channels.
Main Technical Specification
- Rated capacity: 10t SWL, Duty group FEM 2M for heavy-duty frequent operation
- Lifting height: 10 m, rail gauge 3890 mm c-c, VFD control for hoisting & cross-travel
- Ambient: outdoor installation, max ambient temperature +50℃, C3/C4 heavy-duty corrosion protection; weather-proof canopy for motors, brakes and gear-boxes
- Key components: SEW hoist & travel motor with fail-safe brake; VFD from Schneider/Siemens/ABB; galvanized outdoor steel wire rope; forged swivel hook with safety latch; IP55 control cabinet, 24-48V low-voltage control circuit
- Safety devices: overload limiter, upper/lower limit switch, rope-break anti-drop protection, end-stops & buffer, emergency stop, anti-collision unit for adjacent trolleys
- Deliverables: trolley hoist + complete rail system; static & dynamic wheel-load calculation report for civil-structure verification.
- Factory acceptance: witness test required (125% static load test, 110% dynamic load test) before shipment; full set of English documentation, warranty ≥12 months.
Highlights
Strict international bidding project, all design calculation, material certification, and witness inspection and anti-corrosion measures must comply with European FEM standards. Demonstrates our capability for complete overseas heavy-duty water-conservancy projects.
