Double Girder Underhung Bridge Crane & Underhung Crane for
Low Headroom Workshops to get Higher Hook Height

Underhung bridge crane with double girder crane design for low headroom workshops to get higher hook height, up to 16 ton. Check underhung crane now.

Double Girder Underhung Bridge Cranes are ideal for applications requiring additional headroom under runways. Runways can be built into the building as ceiling mounted or suspended runways. Notched bridge beams allow for a low headroom design that takes advantage of the runway's depth. Double girder under running bridge cranes have greater spans and capacities.

Double Girder Underhung Bridge Crane

• Lifting Capacity of underhung crane : 1~16 ton
• Span of underslung crane: ≤20m
• Lifting height of underhung crane : 6/9/12/18m (according your needs)
• Voltage of underhung crane: 220-660V 50/60Hz 3Phase
• Working class of under running crane: A3, A4
• Ambient temperature of underhung crane: -25~40℃
• Widely used for low ceiling workshop and facility where higher hook height.

Features of double girder underhung bridge crane

• Hang from a building's roof or superstructure; simple and reliable installation; low cost.
• Fast and reliable material transportation in a specific area, as well as precise positioning of various components.
• Greater lifting height and span when compared to a single girder underslung overhead crane.

Standard features of double girder under running overhead cranes

• Double girder underhung bridge cranes come in a variety of configurations, including wide flange, patented track, and custom fabricated box girder construction.
• Trolley hoists can be suspended from the bridge's lower flange or modified to operate on rail or bar on top of the girders for maximum hook height.
• End trucks are available in four-wheel or eight-wheel (bogey) configurations for increased capacity and spans designed to run suspended from wide flange or patented track runways.
• Industrial enamel paint finish in safety yellow (additional colors available upon request)
• Capable of interlocking systems that allow a load to be transferred from a crane in one bay to another or to a monorail.

Additional features & options based on your hoisting needs:

• Dual hoists, for synchronized operation and seperate operation.
• As a backup, a radio remote control with an independent traveling push button station is available.
• Travel limits on trolley, hoist or bridge motion.
• Anti-collision.
• 1000:1 speed control on Variable Frequency Drives (VFD).
• Control boxes that are heated and/or air conditioned.
• Warning lights and horns are used.
• Bridge catwalks and service platforms.
• Readout of weight/scale.
• Magnets.
• Reels  cable.
• Bottom powered block.
• Epoxy paint for corrosive or outdoor environments.
• Attached to the bottom of the bridge girders is an underhung hoist trolley unit.
• Spark proof, food grade, and explosion proof.
• Electric wire rope or chain hoists can be mounted.

Single girder vs. Double girder underhung bridge crane

Single Girder Underhung Bridge Crane

• Lifting Capacity: 1~10t
• Span: ≤20m
• Lifting Height: 6/9/12/18m (according your needs)
• Voltage: 220-660V 50/60Hz 3Phase
• Working Class: A3, A4
• Ambient Temperature: -25~40℃

Double Girder Underhung Bridge Crane

• Lifting Capacity: 1~16t
• Span: ≤20m
• Lifting Height: 6/9/12/18m (according your needs)
• Voltage: 220-660V 50/60Hz 3Phase
• Working Class: A3, A4
• Ambient Temperature: -25~40℃

Underhung bridge cranes can be single or double girder. Double girder underhung bridge cranes are frequently used for longer spans and greater capacities.

• A single girder underhung bridge crane is designed to save money, whereas a double girder underhung bridge crane is intended to increase lifting capacity, allowing it to lift up to 16 ton loads and materials.
• Single girder bridge crane has lower wheel pressure than double girder overhead crane.
• Double girder underhung bridge crane expect large height and lift capacity.

Benefits of underhung bridge crane

• System expansions are simple and affordable.
• Straight rails produce simple, reliable, and affordable installations.
• Effective spanning abilities remove the need for expensive extra supporting structures.
• Raised tread tracks offer improved durability and safety.
• Flexible suspensions have a longer lifespan and require less maintenance.

We are capable of designing complicated crane projects for a variety of industries, ranging from 5t to 500t outdoor gantry cranes, jib cranes, and container cranes to 0.5t to 500t outdoor material handling lifting systems. Just leave us what your lifting requirements is, and check what we can do to save your overhead crane cost.

How to select double girder underhung bridge crane for your application

If you're unsure about which overhead system is better for your facility and your lifting requirements, consider the following factors:

• Are there existing support columns in your building, or will you be installing new engineering columns?
• Are there existing runways that can support the overhead that will be installed on?
• What are crane specs needed, such as the lifting height, hook approach, and rated load capacity.
• What are the overhead room in your facility, adequate or low ceiling ?

You can have a discussion with one of our specialists and go over these details. They will help you choose a crane system that achieves the ideal mix between efficiency, suitability, durability, and affordability.
