Single Girder
Semi-Gantry
One floor rail. One building runway. Full gantry performance — without the civil works. Capacities to 20 T, spans to 50 m, for indoor and outdoor facilities where building structure can share the load.
Single Girder
Semi-Gantry
Space-Efficient Design
One leg travels on a ground rail, the other rides an existing building runway or wall bracket. No second ground rail, no extra foundation — ideal when the load-bearing capacity of your shed is limited or a runway already exists on one side.
High Space Utilisation
Unobstructed shop-floor movement with no columns interrupting the working lane. Special wheels available that eliminate guide rail obstructions entirely — keeping your production floor clean and safe.
Robust & Low-Maintenance
Sealed bearings lubricated for life, energy-efficient motors, IP55 protection on all panels. Designed for outdoor environments with A5 duty grade — built for long service intervals and minimal downtime.
The Right Choice When One Side Has Structure
The Single Girder Semi-Gantry crane is engineered for facilities where a full gantry is cost-prohibitive or unnecessary — but a standard overhead crane can't reach the required span or outdoor area. One end beam rides on a floor-level rail; the other uses your existing building runway, wall bracket, or column — sharing the structural load with minimal additional civil work.
With capacities up to 20 tonnes, spans from 3 to 50 metres, and a lifting height of up to 15 metres, it covers moderate-to-heavy workflows in fabrication bays, steel yards, machinery shops, warehouses, and maintenance areas — indoors and outdoors, up to 50 °C ambient.
Available with pendant or radio remote control, and optionally with open, closed, or air-conditioned operator cabins. Power supply via shrouded DSL, cable reeling drum, or diesel generator mounted on the crane.
- Saves investment vs. full gantry — no second ground rail or foundation
- Saves production space vs. overhead crane — one side independent of structure
- Preferred when shed load-bearing is limited or runway exists on one side only
- Unobstructed floor movement — optional guide-rail-free wheel system
- Adjustable span and height — adapts to site as operations change
- Easy access to all major components — reduced service downtime
- Anti-sway, anti-collision, anemometer-ready for demanding outdoor sites

Typical Applications
Fabrication & Steel Yards
Precise handling of steel sections, coils, and heavy fabrications without obstructing the shop floor.
Warehouses & Logistics
Loading, unloading, and stacking across large warehouse bays using existing building structure.
Machinery & Maintenance
Safe removal and installation of heavy machine components, engines, and industrial equipment.
Glass & Precast Concrete
Gentle, controlled lifts for fragile or oversized panels in glass plants and precast yards.
Sewage Treatment Plants
Outdoor-rated, corrosion-resistant configuration for lifting pumps, screens, and plant equipment.
Mining & Heavy Industry
Rugged A5-grade construction handles demanding production cycles in extreme environments.
Shipyards & Ports
High-capacity lifts in open yards where one side of the facility has existing crane infrastructure.
Timber & Plastics
Repetitive, high-cycle material handling in timber yards and plastic production facilities.
& Hook Reach
Our compact crane design ensures full utilization of every metre. Increase production in facilities with limited ceiling height.
High Uptime
Maximize longevity with oil-bath gearboxes and large-diameter rope drums. VFD systems minimize mechanical stress.
Load Control
Eliminate load sway and vibration. Our cranes deliver precise positioning and smooth VFD deceleration for maximum safety.
