Overhead Double Beam Bridge Girder Erecting Concrete Launcher Crane for Railway
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.
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.
