We provide superior quality explosion proof cranes with advanced technology and reasonable price to increase your work efficiency as well as your profits. The cranes are specifically designed for explosive or flammable environments like coal mine and chemical plants. We are the trusted overhead crane manufacturer and supplier in China. With our expertise and experience in crane design and manufacture, we have the capability and knowledge to provide custom built cranes for special lifting requirements. We offer experience with Class 1, 2 and 3; Division 1 and 2; Groups C, D, E, F, and G. Spark Resistant features available for all products – overhead bridge cranes, trolley hoists, and custom lifting devices.
The explosion proof bridge crane mainly consists of a bridge, trolley traveling mechanism, crab and electrical appliances.
Widely used in transfer, assembly, check and repair as well as load and unload at mechanic processing workshop, warehouse, goods yard and power station. Also they can also be used instead of a common double-girder overhead crane at production workshop in light textiles or food industry.
General Classification Of The Explosion Proof Bridge Crane
For sake of safety of the explosion-proof environment, there are two explosion-proof cranes, according to the explosion-proof category. One is Explosion-proof bridge crane for coal mine; the other is explosion-proof bridge crane for the factory.Explosion-proof bridge crane for coal mine:
1. It is mainly responsible for the coal mine work on the parts of the ground and under the ground.
2. Explosion-proof bridge crane for factory:
The crane is mainly used in the environments with combustible gases or flammable mixtures and other dangerous places.
So if you need any advice or products, we are glad to hear from you. And provide our professional service and high-performance crane products to you.
What Are The Safety Features Of The Explosion Proof Cranes?
1. Protection against Overloading
2. Temperature Control of Motors
3. Asbestos-free Brake Linings
4. Two Hoisting Speed Ratio 6:1
5. Two Travelling Speeds Ratio 4:1
6. Full span maintenance walkway with access gate
7. Anti-Derailment Device on Crane and Crab Unit, Non-Sparking Type
8. If you want to know more specific information please let us know.
Different Parts Of Overhead Crane
Because of its work environment, the explosion proof crane should withstand all imposed loadings, with a maximum deflection of 1/750th of the span which is driven by a matching pair of braked motors. And its drive is transmitted through a direct, maintenance free, and gearbox via hardened and ground helical gears in a sealed oil bath. While the operation is via a single reversing contactor type controller, with an automatic slow to fast speed timing device to provide smooth acceleration and a balanced tandem operation.
Prior to packing & protected for transportation, we assemble the crane in our workshops, according to our standard testing procedure, which would include full dimensional and functional tests of all crane operations including limit switches. All the above design provides you a safe work environment in your workshop. Then, you can obtain higher yield in steel mill industry.
We are OEM manufacturer, also provide you various of crane products for general usage or special usage. Our products include electric chain hoist, electric wire rope hoist, Double girder open winch, single girder crane, double girder crane, gantry crane, general crane, the Flexible Light crane, jib crane, explosion-proof crane, and hook blocks, Lift table and all kinds spare parts for explosion proof cranes and Hoist etc. Full series of Materials handling solution, We can provide one-stop services including presale technical support and after-sales service system to free our customers from worries.
At last, hope the above information would be helpful for you. Thus, if you have any questions, please let us know, we will be glad to hear from you.
