Hooklift semitrailer (roll-off tipper): The flexible concept for special applications (38 t concept)
Chassis: Steel frame weldment made of high-quality fine-grained steels/ 2 in. kingpin screwed underneath/ reinforced pneumatic running gear in heavy duty version, single-bladed pull rod in heavy version, wheelbase 1,810 mm/ 12 t BPW tilted roller bearing axles, axle thickness reinforced to 15 mm, disc brakes 430 mm/ automatic venting of the air bellows and lowering on the rear axle during container exchange/ single-wheel plastic mudguard/ rear lights mounted above underride guard
Body: VDL hooklift system (roll-off tipper) with 25 t lifting capacity/ container lengths up to 7.00 m/ hook height 1.57 m according to DIN 30 722 part 2, different versions and many optional equipment are available for selection/ version with wireless remote control and three double-acting control units: 1st function: pick-up or tip container, 2nd function: push container forwards or backwards resp., 3rd function: lock container hydraulically. The main functions of the roll-off tipper are controlled by sensors.
Operating principle: When picking-up or tipping the container, the air bellows of the trailer are being deflated by means of a pushbutton valve, the chassis lowers automatically and lies on the rear axle. A rear axle support or a support pulley are thus not necessary. The roll-off container pick-up angle is reduced due to the lowering process. Due to the improvement of the kinematics, the lifting capacity is increased.
