We design and supply the STS 250 modular transfer trolley system, fully customized to suit complex shipyard logistics and demanding operational loads.
Stacker trolley composition:
- Self-propelled modular stacker trolleys integrated with synchronized steering systems for stable movement of heavy marine cargo.
- Autonomous hydraulic power units (HPUs) with selectable electric or diesel drives, ensuring continuous high-pressure operation.
- Rail-mounted hose distribution carts for organized hydraulic routing.
- Rigid and articulated inter-trolley couplings to ensure mechanical stability and hydraulic continuity.
- Flexible high-pressure lines with industrial-grade quick connectors for rapid deployment and safe disassembly.
- Under-keel distribution beams tailored for ship hull stabilization during transfer.
- Reinforced structural steel longitudinal beams forming the load-bearing skeleton of the STS 250 system.
- Heavy-duty cross-frame connections improving rigidity and vibration resistance.
- Hydraulic centering units for precise alignment of cargo during positioning and movement.
The STS 250 ship transfer system supports industrial requirements for safe, automated heavy-load motion across limited-access or variable terrain environments in shipyards and production zones.
This solution is critical for smooth handling of vessels, modular hull sections, or oversized mechanical units in both construction and repair phases.
Features and benefits
Each STS 250 solution can be adapted based on site layout, operational climate, and load profiles. Trolleys are engineered for payload capacities ranging from 80 to 420 tons and are optionally submersible for use in marine docks and slipways. We offer both powered and non-powered variants depending on integration needs.
Compact trolley designs offer simple storage and excellent maneuverability in confined zones, while the larger high-capacity modules feature oversized wheels for stable navigation over unprepared surfaces.
System performance highlights include:
- Rotary axle technology paired with heavy-duty hydraulic lifting cylinders.
- Remote-operated lifting and descent systems for increased safety during deployment.
- Synchronized multi-axle steering for controlled cargo motion with minimal lateral stress.
Every unit in the STS 250 system is equipped with precision hydraulic actuators, allowing smooth elevation of heavy loads and controlled weight distribution across the trolley set.
Drive technology includes electric and hydraulic versions. Non-driven trolleys can be maneuvered via winches, tug units, or crawler tractors.
The hydraulic power can be deployed from individual trolley-mounted HPUs or via a centralized hydraulic station supplying pressure through high-pressure hose networks.
Custom equipment development
When investing in a ship transfer solution such as STS 250, performance reliability and build quality are critical. Our engineering offering includes:
- Optimized pricing strategies tailored to your project's scope and technical complexity.
- Detailed configuration approval, pre-shipment inspection, and factory testing of full systems.
- Zero-defect policy ensured through rigorous validation and documentation before delivery.
- Long-term expertise in development and deployment of modular shipyard transport systems.
The STS 250 stacker trolley configuration allows for adjustable track gauges from 1000 mm to 1580 mm to accommodate existing shipyard infrastructure. This solution represents a high-precision, heavy-duty transport platform for industrial and maritime applications.
