This video shows a 2 ton underhung bridge crane designed for a low headroom workshop with a ceiling mounted single girder configuration. The bridge crane travels underneath the runway structure, making efficient use of the available workshop height and floor space.
The 2 ton ceiling mounted overhead crane, also known as a 2 ton suspension crane, under running bridge crane or underslung overhead crane, is suitable for workshops where conventional floor-supported runway columns are not preferred or where available headroom is limited.
The 2 ton single girder underhung crane can be supported from the building roof structure, runway beams or engineered suspension points. The bridge end trucks travel along the lower flange of the runway beam, while the electric hoist moves along the crane girder to lift and position the load.
For a 2 ton low headroom overhead crane, the hoist, bridge girder, end carriages, runway beam and suspension structure should be designed as one system. The actual hook height depends on the building height, runway elevation, girder depth, hoist dimensions and required safety clearance.
The main technical parameters include 2 ton lifting capacity, crane span, lifting height, runway length, available headroom, runway beam size, duty class, hoisting speed, travelling speed and power supply. Yuantai engineers review these parameters together before confirming the final crane configuration.

A 2 ton underhung bridge crane is a single girder overhead travelling crane with a rated lifting capacity of 2 tons. Unlike a conventional top-running crane, the bridge travels underneath the runway structure.
The end carriages are supported by the lower flange of the runway beam, allowing the bridge to travel along the workshop. This under-running arrangement can make good use of existing ceiling structures and can reduce the need for floor-level runway columns.
For a 2 ton suspension crane, the supporting roof or steel structure must be checked to confirm that it can safely carry the crane dead weight, lifted load and dynamic wheel reactions.
A 2 ton ceiling mounted overhead crane can be a useful solution when the workshop has limited floor space or when installing new floor-supported runway columns would interfere with production.
The main advantage of a 2 ton low headroom underhung crane is the ability to use the vertical space more efficiently. The runway and bridge arrangement can be positioned according to the existing building structure and required hook height.
For workshops with limited ceiling clearance, the engineering team needs to consider the runway elevation, girder depth, hoist dimensions, hook height and safety clearance together.
A low headroom design should not simply reduce the girder or hoist size. The complete crane geometry must still satisfy the required structural strength, stability and operating clearance.
| Item | 2 Ton Underhung Bridge Crane | Traditional Top Running Crane |
|---|---|---|
| Bridge position | Travels underneath the runway beam | Travels on top of runway rails |
| Support | Ceiling or suspended runway structure | Runway columns or building-supported runway |
| Floor obstruction | Can reduce floor-level columns | May require runway columns depending on building design |
| Typical application | Light and medium duty indoor lifting | General industrial material handling |
| Low headroom | Good option when the under-running geometry is suitable | Depends on bridge and hoist configuration |
| Building requirement | Requires adequate structural capacity for suspended loads | Depends on runway support arrangement |
A 2 ton I beam underhung crane can use an I beam or suitable structural beam as the runway member. The crane end trucks travel along the lower flange of the beam.
The correct I beam size depends on more than the 2 ton rated capacity. The engineering calculation should consider the crane span, wheel load, trolley weight, beam deflection, dynamic loading and support spacing.
Yuantai engineers can evaluate the existing I beam or recommend an engineered runway beam when a new ceiling mounted 2 ton overhead crane is required.
The 2 ton underhung overhead crane is suitable for many indoor applications, including:
A 2 ton ceiling mounted underhung crane can be supported from existing steel roof beams, runway beams or dedicated suspension structures. The exact connection depends on the building construction.
The supporting structure must be checked before installation. The calculation should consider the crane self-weight, 2 ton lifted load, wheel reactions, dynamic effects and suspension point loads.
If the existing roof structure is not strong enough, additional steel support beams or a dedicated runway structure may be required. Yuantai engineers can design the crane and supporting structure according to the available workshop conditions.
Yuantai Crane provides customized 2 ton underhung bridge cranes, ceiling mounted overhead cranes, single girder suspension cranes and under-running bridge cranes for indoor material handling.
The crane can be configured with an electric chain hoist or electric wire rope hoist according to lifting height, working frequency, available headroom and application requirements.
Instead of selecting a standard crane only from the lifting capacity, Yuantai engineers evaluate the span, hook height, runway beam, wheel load, building structure, duty class and available headroom before confirming the final design.
Common questions about 2 ton ceiling mounted overhead cranes, single girder underhung bridge cranes, suspension cranes and low headroom crane systems.
A 2 ton underhung bridge crane is a single girder overhead crane with a 2 ton lifting capacity. Its bridge travels underneath the runway beam rather than on top of the runway.
It is commonly used for indoor material handling in workshops, warehouses, machinery plants and other facilities where floor space or headroom is limited.
Yes. A 2 ton underhung crane can be a good solution for a low headroom workshop when the runway, bridge and hoist can be arranged to provide the required hook height.
The final design should consider the building height, runway elevation, girder depth, hoist dimensions and required safety clearance together.
Yes. A 2 ton ceiling mounted underhung crane can be suspended from a suitable roof structure, runway beam or dedicated support system.
However, the existing building structure must be checked to verify that it can safely support the crane self-weight, lifted load and dynamic wheel reactions.
Underhung crane describes a crane whose bridge travels below the runway structure. Suspension crane emphasizes that the runway or crane system is suspended from an overhead building structure.
In many applications, the two terms describe closely related crane configurations. The actual engineering arrangement depends on the building and runway design.
An I beam can be used for a 2 ton underhung crane when its section, span, wheel load and deflection meet the engineering requirements.
Yuantai engineers do not select the I beam based only on the 2 ton lifting capacity. The crane wheel loads, trolley weight, span and support spacing are also considered.
For a 2 ton underhung bridge crane quotation, provide the lifting capacity, span, lifting height, runway length, building height, available headroom, existing beam dimensions, working frequency and power supply.
Photos or drawings of the workshop roof structure are also useful for checking the proposed ceiling mounted crane arrangement.
