How to solve the problem of unloading failure of tower crane from two aspects of circuit and hydraulic circuit

When the tower crane is overloaded or overthrown, the failure of the electrical system or hydraulic system can lead to the failure of the unloading. How to check the circuit and liquid circuit to solve the problem.

MCR295 H20 CATALOGUE MANU

1. Check the circuit

The purpose of circuit detection is to check whether the torque limiter and limit switch can also transmit the electrical signal to the unloading solenoid valve when providing the alarm signal to the panel indicator light. If so, the unloading circuit will be connected to realize safe unloading; otherwise, the safe unloading will fail.

2. Check the liquid route

Check the liquid path, first check the pipe layout, no error, and finally focus on the logic valve, the logic valve is suspected that the one-way valve spring is hard or the valve diameter is small, so that the unloading oil path back pressure is large, resulting in unblocked unloading oil path, unloading difficult. Therefore, when the pressure of an or bn port corresponding to the action is measured under the alarm state.

MCR295 H20 CATALOGUE MANU

It is found that the pressure is about 1MPa, while the pilot pressure of the main valve is only about 0.6mpa, which proves that the doubt is correct. It is the large back pressure in the logic valve that causes the unloading difficulty.
