Learn About The Structure Of Single Girder Overhead Crane
Single girder eot crane is mainly composed of four parts: bridge frame, electric hoist, bridge running mechanism and electrical control device. The overhead crane single girder has the characteristics of reasonable structure and strong rigidity. It can be used with CD1 single-speed electric hoist, MD1 double-speed electric hoist, or European standard electric hoist.
- 1. Metal Structure – The main beam adopts U-shaped groove formed by steel plate rolling, and then is assembled and welded with I-steel to form a box-shaped main beam. The cross beam is also rolled into U-shaped groove with steel plate and assembled into a box-shaped beam. For the convenience of storage and transportation, the main beam and the end beam can be disassembled and transported, and use high-strength bolts to assemble the bridge during installation.
- 2. Travelling Mechanisms – Crane travelling mechanism adopts the separate driving mode, the driving and braking are completed by the conical motor, and the transmission adopts “open-close” gear transmission.
- 3. Electrical Equipment – The motor used in single girder overhead crane is a conical motor with a brake device. The control box is a special electrical control box (when operating on the ground) or a protection cabinet plus cam controller operation control (when operating in the driver’s cab). The overhead crane is equipped with safety devices and has high reliability.

FAQs
Single girder overhead crane is a lifting equipment that is horizontally spanned over the workshop, warehouse and material yard for material lifting.
The bridge frame of the single-beam bridge crane runs longitudinally along the tracks laid on the elevated runway beams on both sides, which can make full use of the space under the bridge frame to lift materials without being hindered by ground equipment.

Single girder:
- The bridge consists of one main girder beam.
- More suitable for light duty and moderate services
- Capacity up to 25 tons
- Simpler hoist and trolley design
- Faster installation and easy maintenance
Double girder:
- The bridge consists of two main girder beams.
- Recommended for heavier-duty applications
- Capacity up to several hundred tons
- Relatively complex in structure
- Larger span, higher work efficiency
Single beam overhead crane falls in two main configurations: top running and underhung system.
Top running single girder crane:
A cost-effective option with capacities up to 20 tons and span length 7.5-31.5m. The crane has low production cost and maintenance cost.
Under running single girder crane:
It has load capacities up to 10 tons and span length 3-16m. The crane has several unique advantages: reduced material cost; excellent side approach; maximum utilization of the building’s width and height; the possibility of using the existing ceiling girder for securing the crane track.
Here are a few questions to help you determine whether a top-running or under-running system is better for your facility and your lifting needs:
- Can you use the existing support structure or build a new support structure?
- Do you already have a runway in your facility?
- The design and layout of your facility and its ceiling height
- Your lifting requirements, such as load capacity, lifting height and hook approach
- How important is free and clean floor space?
AQ-LD overhead crane: the running motor adopts ZDY type cone motor (protection grade is IP44 or IP54, B or F grade insulation) or YSE soft start motor (protection grade IP44 or IP54, F grade insulation. The soft-start motor can effectively reduce the impact when the crane starts.
AQ-HD overhead crane: ABM three-in-one motor for lifting mechanism, ABB or SEW motor for running mechanism, Schneider Electric and inverter, etc.
AQ-LDY metallurgical casting crane: the lifting and running motor adopts a cone-rotor motor with a large starting torque, H-class insulation.
The main girder of an electric single girder overhead crane is the main load-bearing component of the crane, and also serves as the electric hoist running track.
Its cross-sectional form is usually a composite beam formed by welding and splicing I-beam and other steel or steel plates.
Steel material often uses Q235B or Q345B.
The span of an electric verhead travelling crane refers to the distance between the center lines of the wheels at both ends of the main girder of the crane, that is, the distance between the center lines of the cart rails.
The spans of bridge cranes are 10.5m, 13.5m, 16.5m, 19.5m, 22.5m, 25.5m, 28.5m, 31.5m, etc.
According to the load status and utilization level of the crane, the duty cycle of a bridge crane can be divided into A1-A8 level.
Load state refers to the degree of load on the crane, expressed by load spectrum coefficient.
Utilization level refers to how frequently the crane is used.
Duty cycle of some commonly used overhead cranes:
Hook overhead crane:
- For power station installation and maintenance: A1, A2, A3
- For workshops and warehouses: A3, A4, A5
- For heavy workshops and warehouses: A6, A7
Grab overhead crane:
- For intermittent loading and unloading: A6, A7
- For continuous loading and unloading: A8
Overhead crane for metallurgy:
- For feeding: A8
- For casting: A6, A7, A8
- For forging: A7, A8
