Main problem is that the crane is not moving from left to right and vice-versa.

Possible causes:

1. Not enough turning power from the hydraulic crane swing motor which leads to low pressure on the hydraulic system.
2. Leaks on the hydraulic accumulator like damaged shaft, damaged oil seal, o-rings, etc.
3. Others such as defective hose/pipe and fittings, clogged manifold valves, clogged hydraulic filter, defective solenoid valve, etc.

Note:
Pressure is around 1200-1500 PSI when the directional valve is engaged.
Hydraulic oil level is at minimum to normal
