Mixer Drum Jumper

Mixer Drum Jumper

The Drum Jumper is a self-contained emergency power system used to prevent a load of concrete from hardening inside a mixer drum after a truck's main hydraulic system fails. Featuring a gasoline engine and a powerful hydraulic pump, this unit connects to the mixer's hydraulic motor to provide slow rotation (2.5-3 RPM), which is sufficient for mixing in retardants or for discharging the load. This portability and emergency function make it an essential piece of equipment for any ready-mix fleet to prevent catastrophic drum hardening and costly repairs.
