Overhead Double Beam Bridge Girder Erecting Concrete Launcher Crane for Railway

Product Description

Overhead Double Beam Bridge Girder Erecting Concrete Launcher Crane merges an adaptation of a wide range of work, excellent performance, convenient operation, safety structure into a single whole. It has the steel structure of rail type precast beam hoisting rack equipment. This product can be used not only in plain construction, but also to meet the construction of mountain highway slope, small radius curved bridge, skew bridge and tunnel bridge requirements.

Maintenance

Overhead Double Beam Bridge Girder Erecting Concrete Launcher Crane is widely used in factories, warehouses, storage yards and other occasions to adjust the lifting capacity of goods. According to the type of main beam, it can be divided into box beam and steel beam.
Overhead Double Beam Bridge Girder Erecting Concrete Launcher Crane has good rigidity, light weight, low wheel pressure, and simple and reasonable mechanism design. It can meet the needs of various working conditions, making the work more efficient and reliable.
Overhead Double Beam Bridge Girder Erecting Concrete Launcher Crane is economical. This product is made of rolled steel and wire rope hoist, suitable for light load and ultra short span.

Failure of the electrical or hydraulic system can lead to failures in security unloading. Therefore, check from the circuit and liquid path. The purpose of the circuit test is to check whether the torque limiter and limit switch can also transmit the electrical signal to the unloading solenoid valve while providing the panel indicator alarm signal. If so, the offload circuit will be connected for security. Uninstall, otherwise, security uninstall will fail.
Before the torque limiter provides the electric signal to the unloading solenoid valve, the unloading solenoid valve is in a normally closed state, that is, the unloading circuit is disconnected. Once the torque limiter provides an electric signal to it, the unloading solenoid valve is energized to achieve commutation and connect the unloading circuit. .
For this reason, the pipeline on the logic valve side (T1 port) was disconnected, and then it was found that when the torque limiter did not issue a command, the overload unloading solenoid valve Y1 was de-energized, the solenoid valve was not energized, reversed, and there was no pressure. The oil flows out. When the machine enters an overload state, the valve is energized and the hydraulic oil immediately flows out of the pipeline. This means that the torque limiter sends logic commands to the normal program and the unloading solenoid valve works normally. In the same manner, when the limit switch for controlling the overload unloading and the overload unloading solenoid valve Y2 are checked, the operation is also normal, thereby eliminating the possibility of a circuit failure.

Parts Of Crane

Precautions

• Check and maintain the new crane before installation, check whether the parts are defective, whether the main mechanism is intact, whether the surface anticorrosion of the equipment is recorded, and provide installation suggestions.
• Pay attention to the break-in period of the new crane. The break-in period is an important part to ensure the normal operation of the crane, reduce the failure rate and extend the service life. Therefore, full attention should be paid to the use and maintenance of the bridge crane during the break-in period.
• The bridge crane is maintained by professionals, and is supervised and inspected by the installation and maintenance unit. Strictly follow the "cross-operation method" (ie cleaning, tightening, lubrication, adjustment, anti-corrosion).
• Regular professional medical examinations of the bridge crane. Perform maintenance and repairs of the bridge crane multiple times within the specified time, such as cleaning, lubrication, adjustment, disassembly, maintenance, etc.
• The bridging machine and the drivers involved in the installation work, bridging machine, welder, signal line, etc. are special operators. After the physical examination, they were confirmed to be healthy.
• Before lifting, inspect and accept the crane according to the design requirements of the construction plan.
• Various hoisting and hoisting protection measures should be formulated according to the materials, scaffolds and lifting rings in the hazardous work area, which fully meet the plan requirements.
• Prior to lifting and lifting operations, the technology should be disclosed, including component weight, lifting process and precautions.
• When lifting at a high altitude or the driver cannot see the job site or signal, a signal carrier should be provided.
• Kits and tools and other accessories placed in the kit should be used with the lifter and lifting height. Don't throw objects.
• The installation and acceptance of bridge cranes, reassembled lifting machinery should be tested in accordance with regulations, including static load, dynamic load tests, and sensitivity and reliability tests of various devices. Make sure it meets the requirements before use.
