Concrete 300T Launcher Crane A3 - A5 Work Duty Bridge Girder Erection Beam

Concrete 300T Bridge Girder Erection Beam Launcher Crane To Move Girder

Product Description

Concrete 300T Bridge Girder Erection Beam Launcher Crane is a new kind of equipment. In the bridge erection machine, it is more universal, and especially suitable for large tonnage, large span and double deck concrete box girder. In addition, the structure performance of the bridge erection machine is more stable, more convenient to use.

The stress level and deformation of the main girder of the Concrete 300T Bridge Girder Erection Beam Launcher Crane vary with the location of the section. At the same time, due to the action of moving load, the stress level and deformation of the main girder also change at the same position under different working conditions, that is, the theoretical optimal section parameters and dimensions of each section or section of the main girder change. Considering the actual working conditions and manufacturing process, the main beam (excluding the guide beam) shall be of equal height, and the top chord shall be laid with the track of hoisting crane, and the profile height and width of each section shall be the same (that is, the section shall be made of the same steel section and combination). The front supporting leg is provided with a walking mechanism and a hanging device, and the upper part of the middle supporting leg is equipped with a main beam longitudinal drive mechanism. When passing through the hole, the lower chord operates in relation to the front supporting leg and the middle supporting leg, so the profile height and width of each section of the lower chord are the same (that is, the section should use the same steel section and combination).

In the Concrete 300T Bridge Girder Erection Beam Launcher Crane, due to the different stresses in different parts of the main beam, when the profile height and width of each section of the main beam need to be the same, it can be strengthened in the part with a larger stress level.

Structure

The use of Concrete 300T Bridge Girder Erection Beam Launcher Crane depends on the site and work requirements. General Concrete 300T Bridge Girder Erection Beam Launcher Crane generally consists of four components: metal structure, lifting mechanism, operating mechanism and electrical system.
Generally speaking, the metal structure part of the Concrete 300T Bridge Girder Erection Beam Launcher Crane includes the bridge frame, trolley frame, control room, supporting leg, floor beam, saddle and ladder platform, and these metal parts constitute a rough framework of the bridge erection machine. In addition to the lifting mechanism, the trolley frame of the bridge erecting machine also has the running mechanism part of the trolley, which is the key to realize the lifting process of the bridge erecting machine. And the bridge machine's truck running mechanism is mostly on the ground, using four or more wheel mechanism to drive.
The electrical system of the Concrete 300T Bridge Girder Erection Beam Launcher Crane covers all the electrical control equipment on the bridge erecting machine and its work line.

Parts Of Crane

Regular Maintenance

• The working performance and service life of each mechanism of the lubricating bridge erecting machine largely depend on lubrication. When lubrication, mechanical and electrical products maintenance, lubrication refer to their own instructions, go big car, heavy girder truck should be injected once a week grease. Attention should be paid to the broken wire of the wire rope. If there is broken wire, broken stock or abrasion reaches the scrap standard, the new rope should be replaced in time.
• Spreader spreader must be inspected regularly.
• The bridge machine pulley block is mainly to check the rope groove wear, whether there is a crack wheel edge and whether there is no pulley stuck in the shaft.
• The wheel regularly check the rim and tread, when the rim wear or crack reaches 10% thickness should be replaced with a new wheel.
• Bridge machine brake should be checked once per shift. Brake should be accurate, pin shaft must not be stuck. The brake shoe should fit the brake wheel correctly and the shoe clearance should be equal when the brake is released.
