CE ISO Approved Single Girder Overhead Travelling Bridge Crane Industrial Worshop Lifting Machine With Safety Device
Description:
The single girder travelling crane is our flexible crane for almost any application. Even in buildings with low ceilings effective material flow solutions can be achieved for loads of up to 20 tons and spans of up to 39 m. Normally safety clearances below ceilings are not required for single girder cranes within this load range. This allows the optimal use of existing space or can save additional building height costs.
The single girder traveling cranes adapt to different building applications due to their various main girder connection variants. Favorable crane dimensions help to reach optimal highest hook positions.
Santo has the mature technology on developing and producing cranes
especially heavy duty.
Besides, we also provide customized service for your additional
requirements.
Crane Structure:
On a single girder crane, the bridge consists of one girder beam supported on each side by an end truck. The trolley and hoist are most commonly underhung—meaning they run on the bottom flange of the bridge. The bridge itself can either be top running or under running in design.
Top Running Crane:
These cranes have no limiting capacity, meaning they can be built
to go from small capacities to very large capacities. They include
a rail installed on top of each runway, and the bridge wheels move
on the rail instead of the bottom flange of the runway beam. These
cranes are supported by the building structure or runway support
columns, or sister columns, and are ideal for moving extremely
heavy loads.
Under Running Crane:
Often called “underhung,” because the crane wheels are supported by
the bottom flange of the crane runway beams acting as the crane
rail. These types of cranes can allow you to maximize your
facility’s floor space for the production and storage of material
because they are supported by the ceiling trusses or the roof
structure. Or, they can be designed to utilize an existing support
structure (if adequate), or run on a newly-engineered support
structure.
Application:
Single girder overhead cranes are often the cost-effective lifting solution for various applications and industries. Single girder cranes use less material and are more compact and lightweight than a double girder crane, which results in a significant cost-savings in material, freight, and installation. Also, because they only require one bridge beam, these systems typically have less deadweight, meaning they can utilize lighter runway systems and tie into the existing building support structure.
Standard Specification:
A single girder or double girder design will be one of the largest contributors to the complexity and overall cost of a new overhead crane system.
A bridge crane is a type of overhead crane that includes two or more overhead runways built into the building’s support structure. Bridge cranes have different configurations and can be comprised of one or two beams—more often referred to as a single girder or double girder design. Girders can be made of rolled steel or can be fabricated by welding the beams into a steel box design for added strength and rigidity.

Crane Advantage:
■ Single girder bridge cranes are often the most cost-effective
lifting solution for various applications and industries.
■ Single girder cranes use less material and are more compact and
lightweight than a double girder crane, which results in a
significant cost-savings in material, freight, and installation.
■ Also, because they only require one bridge beam, these systems
typically have less dead weight, meaning they can utilize lighter
runway systems and tie into the existing building support
structure.
■ Less expensive due to a simpler trolley design, reduced freight
costs, simplified and faster installation, and less material for
the bridge and runway beams
■ A most economical option for light to medium-duty cranes
■ Lower loads on the building structure or foundations due to a
reduced deadweight. In many cases, it can be supported by the
existing roof structure without the use of additional support
columns.
■ Better hook approach for both trolley travel and bridge travel
■ Easier to install, service, and maintain
■ Ideal for workshops, warehouses, material yards, and
manufacturing and production facilities
■ Lighter load on runway rails or beams means less wear on the
beams and end truck wheels over time
■ Great for facilities with low headroom
