single girder overhead crane end carriages for sale

We use high-quality material and parts in our end carriages that are built to last and to be cost-effective. The end carriage's steel frame is made up of a torsion-resistant box girder that is ready to join the crane girder. The crane girder mounting plates provide superior travel characteristics and a long lifespan thanks to precise manufacturing and alignment.

The end carriages, which come in single beam and double beam varieties, are a lightweight and tiny lifting equipment working mechanism accessory.

As one of the main supporting components of the bridge crane and gantry crane, end carriages are utilized to move the crane. The length of the crane end carriages ranges from 1.2 meters to 6 meters for cranes ranging from 0.5 tons to 100 tons. Both domestic and foreign motors are optional based on your requirements.

End carriage kits in their whole, including wheels, motors, connecting plates for the main girder and side beams, connecting bolts, stamping plates, polyurethane buffers, and more.

Single girder overhead crane end carriages

The end carriages of a single girder overhead crane are box-shaped structures, with the end carriages and main girder rigidly connected, and the end carriages connected by high-strength bolts where the end carriages is disconnected. Each connecting plate is held in place by reamed bolts, and the positioning mark is made at the factory.

Crane End Carriage Wheel

The wheel is a device used to support the crane and the load and to cause the crane to travel back and forth on the track. The material of the wheel is generally ZG430-640 cast steel.In order to improve the wear resistance and life of the wheel surface, the tread surface should be subjected to surface heat treatment, and the surface hardness is required to be HB300-350, and the quenching depth is not less than 20 mm.

We can provide forged and cast crane wheels in a wide range of sizes, also can customize the wheel acc.to customer's special design requirements.

• Capacity(kg):1000-12500
• Working Class(FEM):1Am-4m
• Working Class (ISO/GB):M4-M7
• Lifting Height (m):6/912/18
• Trolley Speed (m/min):2-20

Customized end carriages for Demag Crane

One of our customers from Malaysia told us that his end carriages of a Demag overhead crane have a break-down. After many years of using, the wheels on the end carriages are wear out and the motors often stop. Since it’s an old type overhead crane, there is no such wheels and motors now, but the rest part like main girder is still fine, so he decide to buy a new pair of end carriages to replace the old ones. And this type end carriage need to be customized now. When he request Demag to design a new end carriages for this crane, the price is very high, so he turned to us for help.

One of our Malaysian customers informed us that the end carriages of his Demag overhead crane had failed. The wheels on the end carriages wear out after many years of use, and the motors frequently fail. Because it is an old type overhead crane, there are no such wheels and motors now, but the rest of the structure, such as the main girder, is still in good condition, so he decides to purchase a new pair of end carriages to replace the old ones. And this type of end carriage must now be customized. When he asked Demag to design new end carriages for this crane, the price was prohibitively expensive, so he turned to us to solve the problem.

Yuantai Crane end carriage solution for Demag Crane

As a crane manufacturer for over 30 years, Yuantai Group has produced a large number of customized products for our customers. So one pair of customized end carriages is not an issue for us.

After the customer showed us the layout of the bolt holes on the end carriages, our engineer created a detailed drawing and sent it to the customer for approval.

After reviewing the drawing, one of our customers commented that our end carriages perfectly matched the main girder but that the price was only a third of Demag's. The customer made the deposit payment right away, and by the time these customized end carriages were produced using our skilled workers and precise machines, they were complete.

Yuantai Group is committed to offering consumers specialized products and services so that they get the most value for their money.

Overhead and suspension cranes, as well as single and double beam overhead cranes are all required to use robust end carriages., which is one of the crane's main force-bearing component.However, it may has the problems, due to the errors of production, installation, and improper use. And then the routine maintenance is necessary.

Common end carriages problems are:

• The horizontal section of the end carriages/carriages is deformed, causing the crane trolley to deflect during the running, causing the large wheels to sway.
• The main girder and end carriages are mostly welded joints in manufacturing, and there are more welds connected to the main girder.
• The end trucks will bend outward due to uneven force after the bridge crane is installed and welded, causing the large wheels to be horizontally deflected. The oblique exceeds the error's allowable range, resulting in the phenomenon of derailment.
• The method of attaching steel plates is frequently used when manufacturing crane end trucks to increase the stiffness of the wheel installation position.
• There may be a gap between the steel plates at the location of the trolley’s wheel installation in some dusty, humid, or corrosive gas operating environments.
• If maintenance is not performed, time will cause corrosion between the splints. Finally, the thickness of the steel plate at this position is continuously reduced, and the wheel runs are deflected, causing the rails problem.

If your end carriages needs to be replaced or you need new ones for your newly designed crane, Yuantai crane will provide a suitable solution for your application. Contact us to get your customized crane end trucks for your overhead crane, semi gantry crane and your processed designed cranes.
