500T Girder Beam Launcher Construction Site Use Bridge Erection Crane

Product Description

500T Girder Beam Launcher Construction Site Use Bridge Erection Crane consists of main girder, crane, front legs, rear legs, front leg cylinder, rear leg cylinder and the transverse connection of front, middle, rear legs. The control part is composed of hydraulic system and electric control system. The 500T Girder Beam Launcher Construction Site Use Bridge Erection Crane is characterized by reasonable compact structure and convenient installation, the main standard girder is connected by pin connection. The double girder structure is connected between the two frame girders by welded pipe.

Electrical System

• In fact, the power supply in the 500T Girder Beam Launcher Construction Site Use Bridge Erection Crane is protected by insulation. If the insulator on the equipment is damaged, or the shell is hit or the short circuit occurs, then the short-circuit protection device of the total power supply will react quickly and cut off the power to protect the safety of the equipment;
• The total power supply will also be protected from voltage loss. After the power supply of the system is interrupted, it can automatically disconnect the total power supply circuit; The power will not be energized until the power is restored manually.

Working Process

• The Girder Beam Launcher Construction Site Use Bridge Erection Crane longitudinal movement to do all the preparatory work, requires a position, not allowed to stop halfway.
• The Girder Beam Launcher Construction Site Use Bridge Erection Crane longitudinal running track on both sides of the height requirements of the corresponding level, keep stable. The lateral running tracks of the front, middle and rear legs should be horizontal and the spacing should be strictly controlled. The three tracks should be parallel.
• When installing concrete beams of inclined Bridges, the walking wheels of the front, middle and rear supporting legs of the bridge erection machine should be positioned, and the left and right wheels should be staggered before and after. The spacing can be calculated according to the oblique Angle, so that the supporting legs can run on the same transverse track (please contact the manufacturer for details).
• When the Girder Beam Launcher Construction Site Use Bridge Erection Crane is carrying the concrete beam longitudinally, the leg position of the front leg is required to be tenaciously fixed with the hand hoist (5t) and the transverse track to enhance the stability.
• When installing the bridge with up and down longitudinal slope, the vertical displacement of the bridge erecting machine should be prevented from sliding. For example: use triangle iron block in front and rear of the wheel for protection, especially the middle leg is very close to the beam end, pay attention to the control when shifting.
• The Girder Beam Launcher Construction Site Use Bridge Erection Crane after assembly must carry on the crane retry crane operation, can also be used after the concrete beam test crane, the bridge machine again run in place to start the installation.
• The Girder Beam Launcher Construction Site Use Bridge Erection Crane installation, often pay attention to the safety inspection, each installation of a hole must be a comprehensive safety inspection, found the problem to stop the work and timely processing before continuing the operation. Mechanical and electrical belt failure is not allowed to work.
