Heavy Duty Highspeed Railway 500T Gantry Girder Beam Launcher Crane

Product Description

In addition to the standard bridge operation, the bridge erection machine can also meet the requirements of first and last span erection, curve erection, variable span erection, span continuous beam, combination beam, continuous steel structure, etc. Existing bridge erection, simple support span continuous erection and other working conditions.It has the advantages of simple erection, fixed point hoisting, good lifting stability, high operating efficiency, safety and reliability, easy to adjust span and easy to operate.

Beam Launcher Crane Wire Rope Maintenance

Heavy Duty Highspeed Railway 500T Gantry Girder Beam Launcher Crane is an important mechanical equipment for the construction of the girder. The design of the wire rope is a key part of the bridge erecting machine. Therefore, the maintenance of the wire rope of the bridge erecting machine must not be ignored. To maintain the wire rope, special attention must be paid to the rust prevention of the wire rope in daily maintenance and repair.
First, to do regular oiling is essential for oiling steel wire ropes that are often in motion. New wire rope hemp cores generally contain 12% to 15% grease, while discarded wire ropes only contain 2.4% of grease at the point of greatest loss. At the rope end of the same wire rope, it still contains 12.7% to 14.5% Of grease.
Second, if a new wire rope is changed, care must be taken to prevent knotting and entanglement to prevent unnecessary accidents during use.
Third, we must pay special attention to the replacement of steel wire ropes. Wire ropes are wearing parts. If they are found to be severely worn and broken during use, they must be replaced in a timely manner. Because the wire rope of the bridge crane bears the important function of lifting weight, the maintenance of the wire rope of the bridge crane must be put first.

Inverter installation

Because the inverter of Heavy Duty Highspeed Railway 500T Gantry Girder Beam Launcher Crane belongs to precise power power electronic products, the quality of its on-site installation process also affects the normal operation of the inverter. The correct installation of digital oil painting can ensure the safe and trouble-free operation of the inverter. The inverter requires higher installation environment. In general, the operating temperature range of the inverter is low temperature -10 ℃, and the high temperature does not exceed 50 ℃; the installation altitude of the inverter should be less than 1000m, and the capacity should be reduced if it exceeds this requirement.

The inverter cannot be installed in the place where frequent vibration occurs. For occasions with large vibration impact, anti-vibration measures such as adding rubber pads should be adopted; the bridge crane cannot be installed near the source of electromagnetic interference; Air-contaminated environment; ca n’t be installed in humid environment. Sealed cabinet structure should be adopted as much as possible, and the inverter should be well ventilated to ensure that the control cabinet has sufficient cooling air volume. The typical loss is generally 3% of the inverter power. Calculate the allowable temperature rise in the cabinet.
The installation process requirements of the bridge frequency inverter are as follows:
1. Make sure that all equipment in the control cabinet is well grounded. You should use a short, thick ground wire to connect to the public ground. Its grounding resistance should be less than 4 ohms. In addition, the control equipment (such as PLC or PID controller) connected to the inverter must share the same ground.
2. When using shielded wires or twisted pairs to connect the control circuit, make sure that the unshielded place is as short as possible, and cable bushings should be used when conditions permit.
3. When using shielded and armored cables for motor wiring, ground the shield at both ends.
4. If the inverter is operating in a noise-sensitive environment, RFI filters can be used to reduce conducted and radiated interference from the inverter. In order to achieve the effect, there should be good electrical conductivity between the bridge crane filter and the mounting metal plate.
