Double Girder Overhead Crane 10 Ton S18m H9.5m Low Headroom 1645mm

Low headroom 1645mm on this overhead crane means:

• 1645mm of clear space between the top of the customer's runway beam and the lowest point of the workshop roof
• The crane's bridge structure, trolley, and crab wire rope hoist must fit entirely within this 1645mm envelope
• Standard overhead cranes typically require 2000-3000mm of headroom — this crane is custom-engineered to fit in significantly less
• The 9.5m lifting height is measured from the hook to the rail level, unaffected by the low headroom above

Low headroom design is critical when:

• Existing buildings have limited roof clearance — you need a crane but cannot modify the building structure
• Roof-mounted equipment (HVAC, ducts, sprinklers) occupies the space above the runway beam
• Building height restrictions prevent the use of a taller crane structure

Yuantai Cranes custom-engineers every low headroom crane to fit the exact clearance you have above the runway beam.

The 1645mm low headroom constraint requires several design adaptations on this overhead crane:

• Compact crab wire rope hoist: The hoist is designed with a low-profile drum and compact frame to reduce the height above the bridge
• Low-profile trolley: The trolley frame is compacted to fit within the 1645mm envelope while supporting the crab wire rope hoist
• Bridge structure optimization: The double girder bridge is designed with a lower overall height profile
• Reeving configuration: The rope reeving is optimized to fit within the compact headroom while maintaining 10t capacity
• Trolley travel path: The trolley travels on top of the bridge girders (standard for crab wire rope hoists) but within the low headroom envelope

Performance trade-offs to consider:

• Reduced maximum lifting height: Limited headroom may reduce the usable hook lift compared with a standard headroom crane
• Lower crane travel speeds: Some low headroom cranes have slightly reduced travel speeds to maintain stability
• Higher cost: Custom low headroom engineering is more expensive than standard overhead cranes

A crab wire rope hoist is used on this low headroom crane because:

• Crab design is more compact than single girder hoists: The crab frame with integrated drum and motor can be packaged more compactly
• Higher rigidity in restricted space: The crab frame distributes load evenly across the two girders, resisting bending at 10t capacity
• Flexible reeving for low headroom: The crab wire rope hoist can be configured with reeving (4/1 or other) that fits the low headroom envelope
• Better stability: The crab trolley runs on two rails (1400mm gauge), reducing load swing — critical in restricted headroom operations
• Easier maintenance in tight space: The crab design allows inspection and servicing from above, which is important in low headroom workshops

For a low headroom overhead crane with 10t capacity and 1645mm clearance, the crab wire rope hoist is the standard configuration.

Seven numbers on this low headroom double girder overhead crane drawing must match your workshop, or the crane will not fit or operate correctly:

If any of these seven differ from your workshop, tell Yuantai before ordering — each change affects price and lead time on the low headroom overhead crane.

P30 rail is specified for this low headroom double girder overhead crane because:

• Wheel load: The 10t capacity and 18m span create significant load moment at the end carriages
• Heavier double girder structure: The double girder bridge with crab wire rope hoist is heavier than a single girder crane, and the low headroom design adds structural mass
• Long service life: P30 rail is standard for 10t+ double girder overhead cranes in continuous workshop use
• Standard availability: P30 is a common rail section, easy to source and replace

Do not substitute a lighter rail (P22 or P24) without recalculating the wheel load and dynamic forces. The 10t capacity and 18m span require P30 or heavier.

No — this low headroom double girder overhead crane with crab wire rope hoist is configured for indoor workshop use. The low headroom design is specifically engineered for indoor workshops with limited vertical clearance above the runway beam. Outdoor use would require:

• Different crane type — a gantry crane with ground rails and A-frame legs is more suitable for outdoor use
• Weather protection — outdoor electrical enclosures (IP55+) and anti-corrosion treatment
• Wind load design — anti-wind devices and anchoring for outdoor wind exposure

For outdoor applications, see the MHO 5t-7m A5 Siemens version with anti-wind and anti-toppling design.

To avoid surprises at installation, these items are outside the low headroom double girder overhead crane supply scope unless you specifically add them:

• Runway rail (P30) and rail fasteners
• Runway beam (the crane sits on the customer's existing runway beam)
• Building column reinforcement (if required)
• Site power supply up to the crane isolator
• Erection crane and site lifting equipment
• Local electrical connection and permits

Because the low headroom overhead crane runs on an existing runway beam, the runway beam condition and alignment are critical — the beam must support the wheel load and be aligned for smooth travel. Yuantai can provide runway load drawings as an optional item.

Send these eleven items and Yuantai will issue a free custom low headroom double girder overhead crane CAD drawing, 3D model, and proposal within 24 hours:

1. Clear height above the runway beam (mm) — e.g., 1645mm, most critical for low headroom design
2. Workshop width and runway rail center-to-center distance (span)
3. Required lifting height (m) — e.g., 9.5m
4. Required lifting capacity (t) — e.g., 10t
5. Workshop length / crane travel distance
6. Power supply (V / Hz / Ph)
7. Lifts per hour or hours per day (duty)
8. Runway beam type and capacity
9. Building column capacity (for runway beam support)
10. Longest load length and weight
11. Control preference: pendant, wireless, cabin, or both

The more complete the list, the faster and more accurate the low headroom overhead crane drawing, 3D model, and quote.

This published low headroom double girder overhead crane drawing and 3D rendering are a free technical reference — you may use them to plan your workshop and check fit. A project-specific low headroom overhead crane GA drawing and 3D model are also free for standard configurations. A design fee may apply only for complex workshop conditions, tighter clearances than 1645mm, or specialized customization engineering.
