Main Girder

Technical Standard:

Manufacturing, installation, and usage should all comply with the Chinese crane industry national standard JB/T10219-2001 "Explosion-Proof Beam Cranes."

High-Quality Construction:

Single girder made from premium I-beam steel and U-shaped channel sections for enhanced strength and durability.

Material Specification:

Main components use Q235B, Q345B or Q355B steel, equivalent to Fe37, Fe52, Fe55 providing excellent mechanical properties.

Robust Connection:

Main girders connected with high-strength bolts for stability and easy maintenance.

End Girder

Box Girder Design:

Box structure girder welded with U-type grooves and steel plates, offering light weight, high rigidity, and superior welding quality.

Specialized Wheels:

LB single girder wheels, providing light weight construction and high versatility.

End Buffers:

Buffers installed at end girder ends to absorb impact and enhance stability.

Performance Optimization:

Robust design with specialized wheels and buffers ensures efficient load distribution and operation reliability.

Electric Hoist

Lifting Mechanism:

The surfaces of the BCD, BMD, and HB type hoist are all marked with the "EX"explosion-proof symbol.

Traveling Motor:

High-torque motor for reliable crane movement.

Traveling Reducer:

Speed reduction unit for controlled and precise travel.

Wheel Group:

Heavy-duty wheels and bearings for smooth, stable movement.

Wheel

Forged or Cast Wheels:

High-quality forged or cast wheels for superior strength and durability.

Heat Treatment:

Wheels are heat treated to enhance hardness and resistance to wear.

Load Capacity:

Designed to handle heavy loads and ensure stable movement.

Wear Resistance:

Advanced material processing for extended service life and reduced maintenance.

Control Way

Wireless Remote Control:

The wireless remote allows the operator to move freely around the crane, enhancing flexibility and visibility. It connects wirelessly, ensuring stable signal transmission and includes features such as emergency stop buttons.

Cable Remote Control:

The cable remote provides stable signal transmission through a physical connection, avoiding issues related to wireless interference. It requires the operator to be near the control panel, offering reliable control and response.

Electrical Equipment

Diverse Power Supply Options:

Trolley uses conductor or angle steel for power, with flat or specialized cables for electric hoists, ensuring stable and flexible power delivery.

Independent and Coordinated Control:

Hoist and crane can be controlled separately or together, offering versatility in operation.

Efficient Power Transmission:

Features galvanized slides and cable trolleys for smooth movement, with current collector and flexible cable options for reliable power supply.

Advanced Electrical Control:

Utilizes non-contact speed regulation modules for smooth operation and precise control during hoisting and startup.
