HiSpec Engineering has introduced a unique new Dump Trailer that uses the well proven push-off technology originally designed for the company’s Kompactor range of push-off trailers.
The new HiSpec Push-off PD20 Dump Trailer, which will be displayed for the first time in the UK at this year’s Royal Highland Show, has a heaped load volume of 14.5m3, giving it a carrying capacity of around 20 tonnes, depending on material.
Unlike conventional tipping dump trailers, the PD20 Dump Trailer is offloaded using a hydraulically operated moving floor type headboard that cleanly and efficiently clears the load from the body once the up and over tailgate has been raised. The moving headboard is based on the same mechanism that was developed for the larger Kompactor push-off trailer range and has a push-off capacity of 28,000kg.
This has the benefit that it enables the Dump Trailer to be safely used and offloaded on slopes or at an angle without any risk of the trailer tipping over, or in buildings and situations where there are height restrictions. Where necessary, it also makes it very easy to offload and spread a load while on the move. Once the trailer has been emptied and the tailgate closed, the operator can move off while the headboard is retracting, so avoiding the delay while a tipping trailer is lowered, and as a result turn around times are reduced.
For maximum durability, the floor of trailer body is constructed from 8mm thick Hardox steel, and 6mm Hardox steel is used for the body sides. By avoiding the need for a hydraulic tipping ram and hinge points, the centre of gravity is lower than for a conventional dump trailer. This not only makes the PD20 Dump Trailer very stable on the road, but the load height at just 2.39 metres is reduced and correspondingly it is also far easier to see into the trailer and the load from the tractor cab.
The trailer chassis of the PD20 Dump Trailer incorporates a hydraulically sprung drawbar fitted with a bolt-on swivel hitch. The running gear on the PD20 Dump Trailer comprises of a parabolic sprung tandem axle fitted with 127mm round commercial axles. These are fitted with 525/65 R20.5 173F tyres and 420×180 air/hydraulic brakes.
The standard specification also includes LED road lighting, four reversing lights, a strobe beacon and brackets for fitting an up and over sheet.
Joining the new PD20 push-off Dump Trailer on the HiSpec stand at the Highland will be the K36 Kompactor push-off trailer, while from their diet feeder product range there will be a T16 vertical auger feeder. From the extensive muck and slurry spreading product range there will be a 3000 TD-S tandem axle tanker fitted with a dribble bar, a single axle 1350 SA-S tanker plus a HiSpec dribble bar, in addition to a 1000 side spreader.
