Fault automobile crane outrigger four kinds of lists
To clarify the reasons for failure and with the correct diagnosis method, the exclusion of such vehicles and other types of automobile  Hoist equipment  crane outrigger failures are important.
 the common faults are: 1.  lift hoist  work, chassis sinking; 2 outrigger seat automatic whereabouts; 3 Turn power switch legs, the legs move very slow; 4 open legs power switch, leg does not move. Of which the first two fault universal.
