500T Beam Launcher Crane Bridge Construction Crane 30 - 55m Span 50m Max Lifting Height

500T Beam Girder Erection Launcher Cursed Bridge Construction Crane

Product Description

500T Beam Girder Erection Launcher Cursed Bridge Construction Crane is suitable for the construction of bridge for roads, railways and other bridge erection construction site. Its main function is to lift the prefabricated beams, then transported onto the prefabricated pier. Beam Girder Erection Launcher Cursed Bridge Construction Crane has big difference from the general cranes.

Product Advantages

• Strong rigidity;
• Lighter weight;
• Structural design is scientific and reasonable;
• Small installation space;
• High flexibility;
• Unique walking structure features;
• Low investment cost;
• Extensive application range.

Components

500T Beam Girder Erection Launcher Cursed Bridge Construction Crane is a large lifting machine for building bridges. Its structure is composed of a main beam, an upper beam and a front frame, a crane crane, a supporting traverse wheel set and track system, a supporting wheel mechanism, a front hydraulic lifting mechanism, and a rear drive. It is composed of parts such as devices, beams, flat cars, and electrical systems. Different parts have different functions.
Beam: Adopt "A" cross section. Pins are assembled according to the number. Hoisting cranes: There are a total of two cranes. The hoisting mechanism is composed of a hoist, a pulley block and a spreader. Lifting the concrete beam completes the vertical and horizontal operation of the concrete beam and controls the installation of the concrete beam in place. Front and rear support traverse wheel sets and track system: Use the support traverse wheel sets to adjust the direction of the bridge machine's through hole to meet the requirements of curved bridges. Supporting wheel mechanism: A mechanism that realizes the longitudinal movement of the main beam of the bridge erecting machine. Rear drive device: It acts as a rear support and also plays the role of rear drive to drive the bridge via. Beam transport: Equipped with 2 sets of beam transport flat cars, the driving speed is controlled by variable frequency speed regulation to ensure the electrical system: the source of power for each mechanism, through various corresponding protections, to make the main circuit and control circuit operate safely.

The supporting part of the 500T Beam Girder Erection Launcher Cursed Bridge Construction Crane is composed of a main rod and a rotating arm composed of a screw, a jack nut and a vertical rod. The rotating arm can be rotated 360 degrees on the main rod, and a travel switch is provided at the end of the arm to prevent accidents caused by lifting errors caused by operating errors or button failure. Operate the button starter to realize the motor's forward and reverse rotation. The wire rope can be wound and released, and it can be lifted by the pulley of the support part, and the object can be lowered to complete the lifting operation.
