Abstract
ABSTRACT
A side tipping bulk carrying vehicle, the body 1 having a hinge 6 at one side and hydraulic rams 2 on the other side. The rams 2 are two stage, the first stage being single acting and the second stage being double acting. The body is supported on feet 13 so that the hinge 6 and rams 2 do not take the load in the rest position.

SIDE TIPPER SUPPORT SYSTEM
This inv0ntion relates to a side tipper support system for bulk carrying vehicles, more par~icularly to a bulk trailer or semi-trailer in which the trailer body is tilted 5 sideways to discharge the bulk material, the trailer body preferably being a doorless side-tipping body.
The vehicle system as described herein is suitable for handling many types of loose bulk materia!s including sand, coil, min~ral ores and rocks, in any ~0 situation where the material can be unloaded by tipping sideways from the vehicle.
The vehicle may vary from small trailers. body trucks or serni-trailers through to rail cars or heavy off-road vehiclcs as us~d on mining sites.

FIG. 1 shows an end eleYa~ion from the front of the vshicle, the rest position shown in full lines, a partial tip in dash lines, and a full tip in dotted lines.

The body 1 is of simple one piece construction being of high strength and light weight. This type of construction makes the body suitable for construction from 15 lightweight materials such as aluminiurn as well as steal, plastics and composites. A major weight and cost saving is achieved by the elimin~tion of ~he door, hinges and associated hydraulio mechanism which would otherwise be required.
20 The one piece construction and rounded shape of the body makes it rigid enough to be self supporting when loaded thus aliowing the use of a lighter ohassis section than would normally be possible. A further advantage of the ~
self-supporting body is that the hoists 2 for tipping can be mounted cxt~rnally on , ~ the end of the body eliminating the neod for hoist towers protruding into the load 25 space. Another major advantage of th~ rounded shape 14 of the body is the tipping action. By building a straight side slope 1~ into the tipping side of the body, and then rot~ting it, the required tipping an~le 3 can be achieved to discharge the material over the side of the body. The side slope 1~ extends from adjacent the hinge 6 upwardly and outwardly toward the top of the body, 3 0 and the rounded shape 14 ~xtends fr~m the hinge 6, across the body and up tothe top of the body on the opposite side to the side slope 1~. The shape a!so produces a tumbling action in ~he discharge material which rolls out progressively frorn the top of the load instead of sliding. This action almost eliminates wear of ~he body shell.

The chassis beam on each side of the vehicle has been designed for use with U1e semi-trailer use of the invention. it consists of two high tensile ~langes 4supported by a corrugated web section 5. The web section provides for ease of construction with the corrugations holding the beam square during welding and S the completed beam being strong and flexibl~.
The hinge 6 fitted to the body is mounted on a spring loaded ver~ical slide 7. As shown in FIG. 2 therQ can be three hinges along the side of the body. The sliding action of the hinge aliows the load to be lifted off the hinge when the 10 body is resting on the chassis and reapplied to the hinge only during tipping.
The hinge action acting only as a loca~ing device while travelling. The body hasfeet 13 on each side which engage the flanges 4 of the b~arns, thus supporting the loaa ~nd this takes the load off the hinges and the hydraulic rams 2 in the rest or transport position.
The hydraulic system uses a single spool, double actingt power bcyond valve system which ?~llows trailers to bc operated in road train configuration with only one oil supply line running the full length of the road train. If oil pressure is not required a~ one trailer it is passed on through the valve to the next, and so on. At 20 the rear trailer a loop of hose is connected to return the oil supply to the tank via a single retum line whieh runs back the full length of the trailers. This line also returns used oil from each trailer when the hoists are operated.
When a control valve is operated, usually by remote air or electric control, the oil 25 is diverted to the hoists of that trailer. The first stage of the hoists is single acting and simply lifts the body, the second sta~e is double ac~ing and comes into action at position 8 before the body reaches balance point. The counter balance valve fitted to the retuM port of the control valve works with the second stage.This valve prevents oil exiting the return stage of the hoist unless there is 30 positive pressure in the lift stage. The system preverlts the hoist from extending out of control once the loaded passes balance point.
The body once ernptied is retrieved by reversing the control valve which then applies pressure to the return side of the hoists. Once the second side is fully35 retracted the body is again over balance point and will return under its own weight.

For side tipping semi-trailers the skid pla~e 9 tends to lift away from the quick release turntable 10 on the opposite side to the tipping side when tipping resultin~ in damage to the king pin and turntable jaws. To ove~ome this pr~blem a permansntly mounted ball-race turntable may be used, or if a ~uick release facility is required a unique locking system has been designed to relieve the lif~ing load on the turntable. This device consists of an arrangement 11 rnounted to the turntable base which enga~es a semi circular -~ attachment 12 welded under the skid plate locking down the side subject to 1 û lifting thus preventing damage to the king pin or jau~s. The hook has sufficient clearance to freely engage when the tumtable is coupled and track~ around the upper attachment when sl~wing.
By fitting hinges on both sides of the symmetrical body and mounting slightly 1~ larger hoists. centrally tipping to either side can b~ achieved simply by disengaging the hinge pins on the side to be lifted.
Although one form of the invention has been desoribed in some detail it is to bereaiised that the inventlon is not to be limited thereto but can inolude various20 modifications falling within the spirit and scope of the invention.
