10t + 10t Twin Hoist European Overhead Crane for Sugar Mill in Guyana
Project Overview
When a mid-sized sugar processing facility in Guyana prepared for its annual maintenance shutdown, management identified a recurring bottleneck: heavy component handling inside the crushing workshop.They did not simply require a higher-capacity overhead bridge crane. They needed a precision-engineered lifting system capable of roller extraction, full motor handling, equipment inversion, and stable dual-point lifting—within an existing building structure that offered limited headroom but a wide 18.29-meter span.
Yuantai Crane was selected to design, manufacture, and deliver a custom 10t + 10t European-style double girder overhead crane, purpose-built for sugar mill maintenance operations.
The Operational Challenge
Sugar production is seasonal. During crushing season, uptime is everything. During maintenance season, speed and safety define success.The sugar mill house required a crane capable of:
- Removing heavy sugar cane crushing rollers weighing several tons
- Lifting complete motor assemblies (housing included) for overhaul
- Rotating long shafts and rollers 180° for machining and inspection
- Handling asymmetrical loads without dangerous shifting
- Operating smoothly within limited headroom constraints
A conventional single 20-ton hook would not provide the required flexibility or load control.
The Solution: Custom 10t+10t Twin Trolley european crane
Yuantai Crane’s engineering team developed a bespoke European double girder crane featuring a dual 10-ton hoist trolley configuration. This wasn't a standard off-the-shelf unit, but a purpose-built machine designed to integrate seamlessly into the Guyanese facility's workflow.
This configuration delivers both independent and synchronized lifting capabilities.
Technical Specifications
- Configuration: 10t + 10t twin hoist trolleys
- Span: 18.29 meters
- Lifting Height: 8.66 meters
- Single Hoist Trolley Gauge: 1.6 meters
- Duty Classification: FEM/ISO M5
- Power Supply: 415V / 50Hz / 3 Phase
- Control System: Pendant control + Wireless remote control
Performance Parameters
- Hoist Lifting Speed: 0.8 – 5.0 m/min (VFD controlled)
- Cross Travel Speed: 2.0 – 20 m/min (VFD controlled)
- Crane Travel Speed: 8.0 – 32 m/min (VFD controlled)
The M5 duty rating ensures the crane can withstand frequent and intensive maintenance cycles typical in sugar processing facilities.
Engineering, Production, and Delivery
Once the design was finalized, the project moved into a tightly controlled production phase. The double girder structure was fabricated with strict dimensional tolerances to ensure precise rail alignment across the full 18.29-meter span. Each hoist unit was assembled, wired, and factory-tested before integration onto the trolley frame.
Before shipment, the complete system underwent no-load and simulated load testing to verify:
- Hoist synchronization capability
- VFD parameter calibration
- Travel smoothness and braking performance
- Electrical protection system reliability
Remote Installation Support
To ensure efficient project execution, Yuantai Crane provided structured remote installation guidance throughout the erection process. Before installation began, the client’s technical team received a complete pre-installation checklist covering runway inspection, rail tolerance verification, and power supply confirmation.
During assembly, our engineers supported the site team via scheduled video sessions and real-time technical consultation, guiding:
- Bridge girder alignment and bolt torque verification
- Trolley positioning and rail clearance checks
- Electrical panel wiring confirmation
- VFD parameter setup and travel limit adjustment
Why 10t + 10t Instead of a 20 ton overhead crane?
From an engineering standpoint, the decision was deliberate. A single 20-ton hook would concentrate lifting forces at one point and limit the ability to:- Stabilize long components
- Perform controlled inversion
- Adjust lifting height independently
- Reduce torsional stress during maintenance
1. Controlled Equipment Inversion
Operators can raise one hoist while lowering the other to safely rotate rollers and shafts. This eliminates hazardous manual tipping procedures.
2. True Dual-Point Lifting
Unbalanced or flexible components are supported at two independent lifting points.
3. Level Motor Handling
Entire motor housings remain perfectly balanced during disassembly and reinstallation.
The bridge girder and trolley frame were structurally verified to withstand the full 20-ton combined load plus dynamic and eccentric loading factors.

European Compact Design Advantage
Headroom was limited in the existing maintenance bay. A standard hoist would reduce effective lifting height.
The European compact wire rope hoists maximized vertical clearance, ensuring the required 8.66-meter lifting height without modifying the building structure. This eliminated costly civil reconstruction.

Precision Through Variable Frequency Drives
All crane motions—hoisting, trolley travel, and bridge travel—are equipped with VFD systems.This provides:
- Micro-speed positioning down to 0.8 m/min
- Smooth acceleration and deceleration
- Reduced mechanical shock
- Lower structural stress
- Improved operator control
In sugar mill maintenance, millimeter-level positioning accuracy protects bearing seats and machined surfaces.
Environmental Adaptation for Sugar Processing
Sugar mills present unique environmental challenges:
- High humidity
- Airborne sugar dust
- Corrosive conditions
- Continuous industrial use
Corrosion-resistant surface treatment
- High-protection electrical components
- Optimized cable routing
- Enclosed drive systems
These measures extend service life and reduce downtime.
On-Site Operational Impact
Since commissioning, the 10t+10t double-girder crane has become the core lifting system for the maintenance department.- Roller Replacement. Two hooks attach to the roller assembly, maintaining perfect balance during extraction and reinstallation.
- Motor Overhaul. Technicians lift entire motor units safely and precisely without external support equipment.
- Equipment Flipping. Long shafts are rotated in a controlled manner using independent hoist motion.
The result:
- Reduced maintenance time
- Simplified workflow
- Improved worker safety
- Elimination of multi-equipment coordination
One operator can now manage tasks that previously required several teams.
