Buy or hire the AT 4019/27 if...
A tipping, low-bed car transporter from German builder Bockmann, rated to carry a car or light plant up to around 2 tonnes. The tipping bed and integral winch let one person load a non-runner without a separate ramp, which is what puts it in vehicle recovery and plant fleets rather than ordinary car trailers.

The largest Ifor Williams tipper. A 3.6m by 1.95m body is chosen for bulky, lighter loads - green waste, clearance and bark - where volume runs out before weight does, and it is a staple of plant and tool hire fleets. Formerly sold as the TT126.
