Single Girder Beam Casting Foundry Crane Safe Metallurgical Plant Lifting for lifting molten metal and foundary location is ameliorated and designed on the basis of LD type single girder overhead crane. It uses CD/MD model electric hoist as the lifting mechanism which is running at the I-steel under the main girder. This product is widely used in plants warehouse, material stocks to lift goods.
1. This crane is special for lifting molten metal/Hot steel/Ladle
2. The working duty is A5,A6.
3. Special thermal-protective coating is added at the bottom of main girder.
4. Lifting weight is from 2ton ~ 10tons.
5. Working temperature is from -20 ºC to +60 ºC.
Our main product is overhead crane, gantry crane, and electric hoist. Our foundry/Casting overhead crane, electromagnet overhead crane, hanging-beam overhead crane, grab overhead crane is special designed for steel factory. We have many cooperations with top steel factory about crane project in China and abroad
1. Heavy duty double beam overhead steel factory crane .
2. Special used in steel plant.
3. Smooth starting and stopping.
4. Safe and reliable traveling, long life.
5. Heat-resistant electrical equipment and wiring.
6. Crane drive: IP54 or IP44, level F insulation
7. High quality with competitive price.

1. Bridge
The main beam is made of cold-formed U-channel steel and I-beam welded into a solid web beam or steel plate into a box beam. The end beam is a U-shaped channel steel group welded into a box structure, and the main and end beams are connected by bolts and shear flange connection structure or seat structure, which is convenient for installation and convenient for transportation and storage.
2. Operating organization
The operating mechanism adopts the separate driving form (see Figure 1), and the driving and braking are completed by the conical rotor motor. Its advantage is that it can reduce the wear of the gnawing track caused by the skew of the wheel, and it is not easy to cause the failure of the wheel to climb the track and fall off the track. Operating speed: ground operation is generally 20, 30m/min. Generally, it is manufactured at single speed. If users need other speed adjustment methods, they should negotiate with the design department before signing the contract and indicate whether they can be used in the order contract.
3. Lifting mechanism
The crane is equipped with two independent braking devices-the metallurgical electric hoist consisting of a brake and a safety brake (i.e. double brake) and an overload limiter form a lifting mechanism, which can lift heavy objects and move along the main The beam moves laterally.
4. Electrical system
The hoisting motor of the metallurgical electric hoist adopts a cone-rotor motor with a larger starting torque to adapt to the frequent direct start of the crane during intermittent work. In order to adapt to the temperature environment exceeding 40 ºC, the insulation class H class motor is adopted, and the high temperature resistant cable is adopted. The crane is operated by pressing the button switch (flashlight door) to make the contact of the contactor turn on or cut off the power supply of the motor. Its main circuit and control circuit have few electrical components, simple wiring, and convenient use and maintenance. Use heat insulation protection measures outside electrical equipment such as motors.
5. Manipulation form
(1) Ground control: The operator controls the flashlight door button on the ground to control the crane to carry out lifting operations. The crane operating speed is less than or equal to 30m/min.
(2) Remote control: The operator holds the remote control to control the crane to carry out lifting operations.
Note: This product is recommended to use remote control operation as much as possible to protect the safety of personnel.
