300T Beam Girder Launcher Cursed Bridge Construction Crane for Sale
300T Beam Girder 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. The Beam Launching Machine has big difference from the general cranes.
Current collector replacement
300T Beam Girder Launcher Cursed Bridge Construction Cranes are devices that place precast beams on precast pier. Overhead cranes belong to the crane category because their main function is to lift the beam, then transport it to that location and then lower it.
300T Beam Girder Launcher Cursed Bridge Construction Crane is very different from bridge erection machine. The required conditions are harsh and there is movement in the beam or longitudinally. Bridge construction machines are divided into highway bridges, traditional railway bridges and passenger railway bridges.
300T Beam Girder Launcher Cursed Bridge Construction Crane usually consist of three main parts: mechanical, electrical and metal structures. The external image of the viaduct is a single-span slab bridge supported by two ends supported on two parallel overhead rails. Double girder bridge cranes are widely used in indoor and outdoor industrial and mining enterprises, iron and steel chemical industry, railway transportation, port terminals and logistics turnover departments.
Once the double beam bridge crane is powered off, sparks may be generated in the power transmission duct, which may damage the current collector in the equipment. If the problem needs to be improved, on the one hand, the chamfer of the current collector brush can be appropriately increased and smoothed; at the same time, the spring strength and elasticity between the two opposite brushes of the current collector can be increased to ensure that the spring can recover freely.
On the other hand, try to deepen and strengthen the spring seat in the current collector to ensure that the recovery spring of the brush is not prone to threading during operation. On the other hand, make sure that the connection blocks of the two parts of the security slide line are chamfered to ensure a smooth transition for the current collector. At the same time, in order to ensure the normal use of the security sliding line, the operation, maintenance and maintenance of the equipment must be standardized to reduce the possibility of failure.
The bridge crane is a lifting equipment designed for bridge construction. This device is more convenient than other lifting equipment, easy to install and disassemble, has high economic value, and is often used for the mobility of municipal engineering.
The bridge crane can only be used after the operators have been trained and qualified. During the operation, it is necessary to strictly standardize its own behavior and operate in accordance with the operation requirements. Check the equipment regularly to make sure everything is normal before continuing.
When using the bridge crane, we must pay attention to the following points:
1. Make sure that the personnel used are professionally trained and skilled in operation;
2. Regularly maintain equipment, replace parts, and add lubricants;
3. No matter what the problem, all problems must be checked until the problem is completely resolved;
During the operation of the bridge crane, regular inspections are performed and an inspection report is written.
In order to ensure the safe operation of the bridging machine, some routine security checks are required during the operation of the bridging machine. The inspection items and points are as follows:
(1) Lifting height limiter, stroke limit switch and interlocking mechanism have normal performance and reliable security.
(2) The main components meet the security requirements: the opening increase is less than 15% of the original size and the torsional deformation is less than 10%; the wear of the hook bushing is less than 50% of the original size, and the wear of the hook mandrel is less than 5%, without flaking, burrs, Weld repair.
Hooks and pulleys have no obvious defects. The diameter of the steel wire surface wear and corrosion is less than 40% of the wire diameter. The broken wire is less than 10% of the number of twist buses. No breakage, no obvious thinning, no core detachment, dead corner distortion and extrusion deformation. , Annealing, burning phenomenon. The two ends of the steel wire rope are connected. The clamps, clamps and clamps are well connected without looseness. The clamps are not less than 2 and the number of clamps is not less than 3.
There is no crack in the reel, and there is no looseness in connection and fixing; wall wear is less than 20% of the original wall thickness; security coil is not less than 2 turns, and the diameter ratio of the reel to the wire rope meets the requirements. The balance is fixed, and the wire rope should meet the requirements. The brake has no cracks, no looseness, no severe wear, and the dimensions on both sides of the brake gap are the same. It has sufficient braking force, and the brake belt wear is less than 50% of the original thickness.
