SPYDERCRANES™ by FURUKAWA UNIC can be equipped with Automatic Accellerator Control System, which provides control of all four crane operations and the outrigger. When the lever for each function is engaged the axle is moved, idling the engine (slow speed) or raising the axle (high speed). Inclining the lever increases the engine speed: releasing it idles the engine. One hand controls operations that require two hands with other cranes.
(This feature is only available on side controled cranes)
