Underhung Crane 5 Ton S6m H25m High Lift | Underslung Crane Drawing

The 25m lifting height is achieved through several design features:

• Extended wire rope reeving: The NR electric hoist is supplied with drum capacity and wire rope reeving designed specifically for 25m hook travel
• Guide system: The wire rope is guided along a controlled path to prevent slack or tangling at high lift
• Slow, precise lifting speed: The 0.8/5.0 m/min lifting speed gives the operator precise control over the long hook travel
• High-bay crane design: The crane girder and end carriage are designed to fit high-bay workshops with the 532mm total height
• Reinforced lifting mechanism: The hoist motor, brake, and drum are rated for extended duty at 25m lift

High-lift underhung cranes are used in workshops with very tall ceilings or vertical process equipment, where a long hook reach is essential for reaching deep into pits, silos, or tall equipment.

Remote control only is specified on this high-lift underhung crane because:

• Best viewing position: At 25m lifting height, the operator must be able to move to a position where the load and hook are clearly visible — a wireless remote allows this freedom
• No pendant cable limits: A pendant cable would restrict the operator's movement and could interfere with high-lift operations or tall equipment
• Safer operation: The operator can stand further from the load at high altitude, reducing the risk from any falling objects or swinging load
• Ergonomic operation: The operator can work comfortably from the best observation point at floor level, with a clear view of the hook and load
• Communication: If radio reception is a concern, we can specify a hybrid pendant + remote setup for redundancy

If pendant control is also required for specific situations (e.g., maintenance or backup), a dual pendant + remote setup can be specified — contact Yuantai for details.

Eight numbers on this high-lift underhung crane drawing must match your workshop, or the crane will not fit or operate correctly:

If any of these differ from your workshop, tell Yuantai before ordering — each change affects price and lead time on the high-lift underhung crane.

200~400mm rail width is specified for this underhung crane because:

• Wheel diameter Ø130mm — the wheel is designed to run on 200~400mm rail width
• 5t capacity and 6m span: The load moment requires a rail with sufficient head width and web thickness
• High-lift dynamics: The 25m lifting height adds dynamic loads during lifting and lowering, requiring a robust rail
• Standard availability: 200~400mm rail width is common for underhung cranes, easy to source and replace
• Long service life: 200~400mm rail is standard for 5t underhung cranes in continuous use

Do not substitute a narrower rail without recalculating the wheel load and dynamic forces. The Ø130mm wheel and 35.3 kN wheel load require 200~400mm rail width or equivalent.

This underhung crane is configured for indoor high-bay workshop use. For outdoor or high-wind environments, additional engineering and features would be required:

• Different crane type: A gantry crane with ground rails and A-frame legs is usually more suitable for outdoor use
• Weather protection: Outdoor-rated electrical enclosures (IP55+) and anti-corrosion treatment
• Wind load design: Anti-wind devices and anchoring for outdoor wind exposure — at 25m lift height, wind loads are significant
• Rain cover: Protect the crane, hoist, and electricals from rain and snow

For outdoor or high-wind applications, consult Yuantai Cranes for a suitable gantry crane or a weather-protected underhung crane solution.

To avoid surprises at installation, these items are outside the high-lift underhung crane supply scope unless you specifically add them:

• Runway rail (200~400mm) and rail fasteners
• Runway beam and building column reinforcement
• Building structural support for the 35.3 kN wheel load
• Site power supply up to the crane isolator
• High-bay structural verification (building height, roof truss capacity)
• Long wire rope replacement access provision
• Erection crane and site lifting equipment (high-bay installation)
• Local electrical connection and permits

Because the underhung crane operates at 25m lift height in a high-bay workshop, the building structure and installation access are critical — the runway beam and columns must support the 35.3 kN wheel load, and the installation must be planned for high-bay conditions. Yuantai can provide runway load drawings and installation guidance as optional items.

Send these eleven items and Yuantai will issue a free custom high-lift underhung crane CAD drawing and proposal within 24 hours:

1. Required lifting capacity (t) — e.g., 5t
2. Crane span (m) — e.g., 6m
3. Required lifting height (m) — e.g., 25m
4. Rail width (mm) — e.g., 200~400mm
5. Number of underhung cranes required (e.g., 1 unit)
6. Building clear height and roof structure capacity
7. Power supply (V / Hz / Ph) — e.g., 3P 380V 50Hz
8. Duty class — e.g., A5
9. Control requirement — e.g., remote control only, or pendant + remote
10. Load type and weight (e.g., long loads, vertical process equipment)
11. Any special high-bay requirements (e.g., anti-sway, load display)

The more complete the list, the faster and more accurate the high-lift underhung crane drawing and quote.
