ABSTRACT:
A hydraulic shock absorber controller for a wheel crane having a suspension provided with hydraulic shock absorbers. The hydraulic shock absorber controller connects a line connected to the active chambers of the hydraulic shock absorbers and a line connected to the inert chambers of the same before the wheel crane starts running to enable the working fluid to flow rapidly from the compressed chamber to the expanding chamber of each hydraulic shock absorber so that the hydraulic shock absorbers are able to function properly for shock absorbing operation while the wheel crane is running.
