Marble Crane is a type of crane specially produced for marble manufacturers and processors by taking into account the working conditions. widely used in marble loading and unloading, ship and the front yard cargo handling, transportation, stacking operations and other open space.
Types of marble crane such as overhead marble crane and gantry marble crane with lifting capacity up to 550 ton are available.
I. Technical Requirements of Marble Loading Crane:
1. lifting mechanism and operating mechanism running in low speed, in order to improve the prefabrication beam alignment accuracy and reduce the impact on the beam structure.
2. the beam inside the space should be large enough to meet the lifting of prefabricated beams and bridge machine assembly. (Pole machine price)
3. the main steel structure should meet the strength, stiffness, stability under the premise of considering the disassembly and transportation.
4. the use of two crane for lifting prefabricated beams must meet the two loom synchronous operation .
II. Operation and Maintenance Precautions:
1. the crane operator to be trained, qualified before induction.
2. in strict accordance with the crane operating requirements, operating procedures to operate.
3. The mechanical devices, electrical equipment etc, should have regular inspection and maintenance.
4. found that any problems, Gantry crane should be shut down until the problem is removed.

Features for Key Parts
Structure | Lifting motor, gearbox, drum and limit switch are integrated with compact design to save the user's working space. Apply the modular design to enhance its reliability and meanwhile to reduce effectively the cost and time for maintenance. Hoisting mechanism is designed strictly in the relevant FEM standards. | |
Lifting motor | Small starting current, big torque High acceleration Long service life design High speed, low noise | |
Lifting gearbox | Light weight, corrosion resistance. In the hermetically sealed cabinets, the semi-greasy lubricant makes all the gears adequately lubricated in the designed safety using cycle . Every gear's surface-hardened and precisive-lapped ensure smooth operation Smooth running,low noise Corrosion-resistant, maintenance-free | |
Lifting brake | Our lifting motor equipped with electric-hydraulic drum type. The brake is installed in the end of motor, the motor brake is automatically closed when the motor without power to prevent the loading slipping. The brake clearance is no need to make manual adjustment after the first set(by the brake springs the clearance adjust itself), According to safety regulations, we use the brake which braking torque is not less than 1.8 times the rated motor torque. Moving fast, high reliability Maintenance-free, self-adjustment Dust proof design ,long life | |
Drum | Drum is made of high-quality seamless steel pipe by CNC machining. The drum grooves and rope guide can effectively prevent the rope loosen and mixed. The rope is made of imported wire rope with high-strength tensile strength, safety and long service life | |
