At just 74cm wide, this Battery Powered Dumper can access standard single doorways and negotiate to tightest of spaces.
The 'scissor lift' high tip mechanism is ultra strong and can handle the largest of loads to quickly and safely discharge materials to a skip or commercial vehicle.
Quick recharge of the battery pack takes just 5-6 hours and it can run all day (8 hours) on a single charge.
The low gross weight and wheeled drive makes this a fast travel machine, with minimal ground impact. Transport is easy as it can load into the back of a medium sized panel van using a pair of aluminium ramps.
