The chassis of the JOSKIN Trans-KTP 9, 11 and 15 T tipping trailers is 900 mm wide and can therefore be fitted with wide wheels. It is made up of 250 x 100 x 6 mm profile tubes on models 9/45 and 11/45, and of 300 x 100 x 8 mm profile tubes on model 15/45. The driving comfort provided by the whole carriage is ensured by the hitching suspension with cross-springs.
The Trans-KTP 9, 11 and 15 T are fitted with an open drawbar that, given its structure, ensures a very good weight/resistance ratio. Its wide fixing points (same width as the chassis) further improve the manoeuvrability. This solution offers a straight pull/push line and a large vertical clearance at the eyelet, thereby largely absorbing shocks.
The telescopic tipping ram is mounted on a double oscillating frame fitted with greased bearings and integrated in the chassis at a more forward position. This system compensates the torsions due to the tipping strains and effectively protects the ram and body from distortions. The body tipping is also ensured by the two robust hinges including bolted axis with large diameter. The back- and upwards position of the hinges increases the unloading height.
Standard mounted, a safety valve, which is directly placed on the tipping ram, prevents the body from unexpectedly falling down (e.g. when hydraulic hoses break).
Tapered, Light and Strong Body
The bodies of the JOSKIN Trans-KTP construction trailers are made fully of high tensile steel of the HARDOX 450 type, which has very interesting tensile properties, as it takes its initial shape back after deformation. Compared to traditional steel, its tensile limit is indeed 4 to 5 times higher. All bodies, including the doors, are manufactured with 2 steel sheets, without any linking cross-weld. Thanks to this manufacturing process, the empty weight of these tipping trailers is significantly lower and therefore allows transportation of higher payloads, without compromising on sturdiness.
The tapered shape of the body makes sure the contents of the trailer flow out freely.
This unmatched property is further reinforced by the successive folds aiming at smoothing off the edges of the body.
For models 9, 11 and 15 T, two hydraulic pumps with a 55 l capacity are available (PR660: 53 l/min at 1,000 rpm and PR980 : 70 l/min at 1,000 rpm). They can optionally be fitted with a electric or hydraulic control.
