Single Girder Overhead Crane

These cranes are known for their durability, efficiency, and versatility. They can be used for a wide range of applications, from moving raw materials in a manufacturing plant to loading and unloading containers in a shipping yard.

 

The single girder overhead crane is typically designed to operate on a runway system that is attached to the building's overhead structure. The crane moves back and forth along the runway, allowing it to cover a wide area.

 

One of the benefits of a single girder overhead crane is that it can be customized to meet the specific needs of the user. For example, the hoist can be designed to lift a specific weight or to operate in a certain temperature range.

 

Overall, the single girder overhead crane is a reliable and efficient option for lifting and moving heavy loads in industrial settings.

1. Whole set crane

 

2. Main girder

The main beam is the main bearing parts of the crane, its structure is composed of U-shaped groove, inclined cover plate, rib plate and I-steel plate, its upper arc is (1/1000 ~ 1.4/1000)S, when the rated lifting weight and hoist weight is located in the span, caused by the inclination is not lower than the horizontal line, no permanent deformation during normal operation.

 

3. Electric Wirerope Hoist

Electric wire rope hoist is a type of lifting equipment used to hoist heavy loads and it is use on the single girder overhead crane for up and down lifting. It consists of a motor, rope drum, gearbox, wire rope, and lifting hook. The motor drives the rope drum through a gearbox, and the wire rope is wound around the drum. The lifting hook is attached to the end of the wire rope. When the motor is activated, the rope drum rotates, causing the wire rope to wind or unwind, thus lifting or lowering the load attached to the hook.

 

4. End beam

1) Material of end beam uses for crane longitudinal traveling.

2) End beam is made of rectangular steel-pipe or steel plate by welding. the finished end beam get once positioning processed on numeral control machine in order to ensure dimension accuracy and fit tolerance.

3) Each end beam is supplied with wheels with double-wheel rim, buffer and anti-derailing protection device.

 

5. Crane wheel

The high quality wheel set is made of 45# steel die forging, roughing, conditioning and finishing. The hardness of heat treatment is HB305 ~ 385, and the hardness of hardening layer at 18mm depth is not less than HB250. The wheel shaft is made of 45# steel, which is roughed, tempered and finished. The hardness of heat treatment is 250 ~ 280HB.

 

6. Crane hook

A crane hook is a device used in lifting operations that attaches to the load being lifted. It is a metal hook that is designed to withstand the weight of the load being lifted, and it is attached to the crane by means of a chain, rope, or cable. The size and strength of the crane hook depend on the type of crane, the weight of the load, and the height of the lift. Crane hooks are made of high-quality steel and can be either single or double hooks. They come in various sizes, shapes, and configurations to accommodate different types of loads and lifting applications.

8. Sound and light alarm system and limit switch

Every crane will be equipped a sound and light alarm system and so that it is an effective way to keep people safe in emergency situations. It is important to ensure that the system is regularly tested and maintained to ensure that it is in good working order.

 

The limit switch can be widely used in three - dimensional control and travel limitation of hoisting machinery, and it can protect the crane.
