Semi Gantry Cranes
A highly efficient space-saving hybrid crane featuring one A-frame leg traveling on a ground track and the other end riding on an elevated runway system. Optimised for dynamic shop-floor workflows.
Optimise Workflow with Dual-Level Lifting
DBS Engineers' Semi Gantry Cranes are a brilliant design solution that integrates seamlessly into existing factory layouts. By using one ground runway and one elevated runway, they allow overhead EOT cranes and lower workstation portal systems to share the same workshop bays without collisions.
Overhead Interference Prevention
Permits multi-level material handling, leaving the higher workshop space free for primary EOT operations.
Dynamic Dual-Speed Drives
Features independent drive motors at both levels, synchronized perfectly via VVFD to prevent skewing.
Absolute Workspace Safety
Equipped with floor-level obstruction sensors, optical warning indicators, and mechanical limit cutoffs.
Technical Specifications
Technical parameters engineered by DBS for Semi Gantry crane systems.
Lifting Capacity
Standard capacity range from 2 Tons up to 50 Tons, customized to match assembly line workflows.
Custom Span Limits
FEA-optimized bridge structures built precisely to match the offset of ground rails and elevated runways.
Duty Cycle
Class II (Medium Duty) or Class III (Heavy Duty) structures engineered for severe workstation operations.
Power Feed Setup
Shrouded DSL bar channels for elevated runways, with cable chain drag lines for ground assemblies.
Anti-Skew Control
Electronic synchronization drives at the floor level track speed, matching the elevated wheel assemblies perfectly.
Safety Protections
Photoelectric collision barriers, visual flashers, overload limiters, and end-of-rail physical limits.
Industrial Applications
Our Semi Gantry Cranes provide multi-level workflow speedups across major manufacturing hubs.
Automotive Assembly Halls
Precise regional chassis and engine mating under high-capacity main overhead EOT crane systems.
Machining & Tool Shops
Handling die casting frames and heavy tooling sets along localized machine shop walls.
Covered Logistics Bays
High-speed loading of steel structures and pipes from side bays onto active indoor loading trucks.
