Q: What is an underhung overhead crane?
A: An underhung overhead crane is a type of crane that runs along the underside of a runway beam instead of on top.
This design saves headroom and floor space, making it ideal for compact workshops, low-ceiling factories, and warehouses while still allowing reliable material handling.
Q: What is the maximum load capacity of an underhung crane?
A: Most underhung cranes have capacities ranging from 0.5 to 15 tons.
The exact capacity depends on the crane’s span, hoist type, and runway design; for heavier loads, a top-running crane may be more suitable.
Q: Can an underhung overhead crane be installed in a low-ceiling factory?
A: Yes, underhung cranes are designed specifically for low-ceiling spaces.
By traveling beneath the runway beam, the crane requires less headroom than traditional top-running cranes, making it practical for tight or compact facilities.
Q: What is the difference between single girder and double girder underhung cranes?
A: Single girder underhung cranes have one bridge beam, while double girder underhung cranes have two.
Single girder models are simpler, lighter, and cost-effective for light to medium-duty lifting, while double girder underhung cranes can handle heavier loads and longer spans.
Q: How much does an underhung overhead crane cost?
A: Prices typically range from $8,000 to $30,000 depending on capacity, span, and customizations.
Factors affecting cost include lifting capacity, span length, hoist type, electrical setup, and optional protective or environmental features.
Q: How do I select the right underhung crane for my facility?
A: Consider the span, lifting height, load weight, hoist type, and environmental conditions.
Evaluating these factors ensures the underhung overhead crane fits your facility’s needs, operates safely, and can handle future upgrades if necessary.
Q: What types of hoists are suitable for underhung cranes?
A: Wire rope and chain hoists are commonly used on underhung overhead cranes.
Wire rope hoists handle heavier and frequent loads, while chain hoists are compact and better for lighter tasks or lower lifting heights.
Q: What maintenance is required for an underhung crane?
A: Regular lubrication, inspections, and part replacements are essential.
Check the bridge, trolley, hoist, hooks, chains, and limit switches to ensure smooth and safe operation while extending the crane’s service life.
Q: How difficult is underhung overhead crane installation?
A: Installation is generally simpler than top-running cranes but requires careful alignment and electrical setup.
Proper runway beam alignment, secure electrical connections, and pre-operation safety checks are crucial to ensure the crane operates reliably.
Q: Are underhung overhead cranes suitable for industrial material handling?
A: Yes, underhung cranes are widely used in manufacturing, automotive, assembly lines, and warehouses.
Their low headroom and compact design allow efficient and safe lifting of small to medium loads in busy or constrained facilities.
Q: Can an underhung crane be relocated to a new facility?
A: Yes, underhung cranes can often be reinstalled in another location.
Their lighter bridge and runway requirements make relocation feasible, though professional assessment is recommended to ensure proper installation and safety.
Q: Where can I buy a reliable underhung overhead crane?
A: Trusted suppliers like Yuantai Crane provide CE and ISO-certified underhung cranes with customization options.
Look for a certified manufacturer that offers after-sales support and free quotations, ensuring the crane’s capacity, span, and hoist type meet your facility’s requirements.
