DQCRANES underslung overhead travelling crane is particularly suited to complicated space and construction conditions as the crane track is mounted onto the ceiling instead of onto free-standing or building columns. Thus best possible results are achieved even in tight spaces and difficult conditions.

The single girder underslung
bridge cranes offered by DQCRANES have load capacities of up to 10 tons and spans of up to 16m. A comprehensive programme of accessories and crane kits is also available for DQCRANES' under running bridge cranes.
Underhung Crane Project in Canada
- Client: Canadian Agricultural Machinery Maintenance Facility
- Objective: Design and export a 5-ton single girder underhung crane compliant with European standards to enhance maintenance operations.
Client Needs and Industry Challenges
The client, a Canadian company involved in agricultural machinery maintenance, faced the challenge of efficiently handling heavy machinery components. Maintaining and repairing agricultural equipment often requires lifting and moving bulky and heavy parts, such as engines, transmissions, and large tires. Without a suitable lifting solution, these tasks can be time-consuming, labor-intensive, and potentially dangerous. The client sought a reliable and cost-effective solution to improve their maintenance processes, reduce downtime, and enhance workplace safety.
DQCRANES' Solution
DQCRANES provided a tailored solution by designing and exporting a single girder underhung bridge crane. This type of crane was well-suited to the client's needs due to the following factors:
- Lifting Capacity: The 5 ton lifting capacity was sufficient to handle the weight of most agricultural machinery components.
- Single Girder Design: A single girder crane is a cost-effective option for lighter lifting requirements.
- Underhung Configuration: The underhung design maximizes the available headroom within the maintenance facility and doesn't require supporting columns, thus optimizing the use of space.
- overhead crane System: An overhead crane system provides excellent coverage of the work area, allowing for precise positioning of heavy loads.
- Capacity: 5 tons
- Span: 5.6 meters
- Lifting Height: 5 meters
- Lifting Mechanism: NR series European type Electric wire rope hoist
- Lifting Speed: 0.8–5.0 m/min (Inverter control)
- Traveling Speed: 2.0–20 m/min (Inverter control)
- Working Class: A5 (FEM 2m)
- Protection Class: IP54
- Insulation Class: F
- Power Supply: 380V/50Hz/3-phase
Design & Engineering

Hoist Mechanism:
- 5 ton capacity electric wire rope hoist with FEM standards.
- Variable Frequency Drive (VFD) for smooth speed control (0.8–5.0 m/min).
Travel System:
- end carriages with Q235B carbon structural steel, quality wheels, and powerful motor for quiet operation.
- Dual-speed travel motors (2.0–20 m/min) for precision.
Control System:
- Pendant control with ergonomic design.
- Emergency stop, overload protection, and upper/lower limit switches.
Safety Systems:
- Phase protection system; Anti-collision system; Overload protection system; No-voltage protection system; Thermal protection system; Over-current protection system.
- Lifting limit protection system; Traveling limit protection system; Ground protection system; Emergency stop protection system; Polyurethane buffer system.
Benefits
The NLX 5 ton single girder
underhung overhead crane provided by DQCRANES offers several key features and benefits:
- Increased Efficiency: The 5 ton suspension crane enables technicians to quickly and easily lift and move heavy parts, reducing the time required for maintenance tasks.
- Enhanced Safety: By eliminating the need for manual lifting, the underslung bridge crane significantly reduces the risk of workplace accidents and injuries.
- Improved Productivity: Faster maintenance translates to less downtime for agricultural machinery, increasing overall productivity.
- Cost-Effectiveness: The single girder design provides a cost-effective lifting solution without compromising performance.
- Customization: DQCRANES was able to customize the crane (top running crane and underslung crane) to meet the specific needs of the client, ensuring optimal performance and integration with their facility.
Export & Logistics
- Packaging: Weatherproof crating for transatlantic shipping.
- Documentation: Customs clearance with HS codes 842611 (overhead cranes).
- Lead Time: 12 weeks from design to delivery, expedited to meet client deadlines.
Installation & Commissioning
- Runway Preparation: The Client provided structural calculations for roof support.
- Testing: 125% static load test (6.25 tons) and 110% dynamic test (EN 13001).
- Inspection: Operational checks for speed, braking, and safety systems.
- Training: Remote technician training for operation and maintenance.
