There are longer cranes in the same series the 5000XL & 5000XXL each having 8.8m & 9.8m reach respectively. The crane shown here uses 2 x hydraulic cylinders for the extensions as opposed to chains, so less wearing parts. This particular crane was ordered with Hydraulic Servo valves these are cheaper than full electric but not as convenient to mount due to piping. Anyway a nice compact crane on its way for some hard work feeding a chipper, complete with Energy Grab .
