Double Beam Wheel Gantry Crane

Description

The double beam wheel gantry crane is a type of gantry crane with a horizontal bridge structure consisting of two parallel main beams, which is supported by tires and travels on the ground without rails. The gantry structure is formed by connecting the main beam with rigid and flexible support legs, and the main beam is usually designed as a box shaped double beam to enhance stiffness; The power system is mostly driven by internal combustion engines (such as diesel engines), which use electric motors to achieve walking, lifting, and variable amplitude mechanism actions. It has good maneuverability and can flexibly turn and transfer work positions in yards and other places

Working Condition

Temperature conditions: The working temperature range of a conventional double beam gantry crane is -20 ℃ to+45 ℃. In extreme temperature environments, it is necessary to choose low-temperature equipment or install cooling systems to ensure the normal operation of the equipment.

Humidity and corrosive environment: The relative humidity of the working environment should be controlled at ≤ 90% (no condensation). In high salt spray and high humidity areas such as coastal ports, equipment needs to adopt anti-corrosion design, including spraying anti-corrosion paint on the surface of steel structures, selecting moisture-proof electrical components, and using hot-dip galvanized or stainless steel materials for metal parts.

Wind conditions: The working wind speed of the equipment is generally not greater than 12.5m/s (level 6 wind), and the operation needs to be stopped when the wind speed exceeds this value. In non working conditions, the equipment needs to be equipped with windproof anchoring devices, and the maximum non working wind speed that can be tolerated needs to be determined according to the model and region.

Other environmental restrictions: The work area should avoid excessive dust and flammable and explosive gases. In dusty areas, dust covers need to be installed for motors and control cabinets; In flammable and explosive environments, explosion-proof electrical equipment should be selected.

Technical Data

Spare Parts

Main beam

The main beam is a box beam or H-beam structure, welded and formed from steel plates. The steel plate material is domestic steel (Q235B). The vertical winding is in accordance with Chinese national standards. All steel plates are subjected to shot blasting pre-treatment to achieve Sa2.5 level standardization. Before welding, the steel plates are carefully inspected and cleaned, usually by automatic welding machines (MIG or semi-automatic welding).

Ground beam

The lower beam is also a box-shaped structure, mainly composed of cover plates, webs, ribs, flange supports and other parts. The production process is similar to that of the main beam and other box beams. After the lower beam structure is completed, the bent plates are assembled according to the drawing. The flange support is welded to the lower beam after the lower beam is made to ensure the level of the flange surface. When the lower beam and the leg are assembled, the flange on the flange made on the leg is welded to the leg. The appearance quality and geometric dimensions of the lower crossbeam after production meet the requirements of the standard GB14406-93.

Trolley

The trolley is an important component of the gantry crane, its operating speed is usually between 20~50m/min, and the lifting speed can reach 3~8m/min. The design of the spacing between car tracks is flexible, generally ranging from 1.5 to 3 meters, to meet the operational needs of different spans.

Crane remote control

Industrial wireless remote control is a remote wireless remote control device specifically used to control construction machinery or industrial equipment.
