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.

Description

SIDE TIPPER SUPPORT SYSTEM
This invention relates to a side tipper support system for bulk carrying vehicles, more particularly to a bulk trailer or semi-trailer in which the trailer body is tilted 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 materials including sand, coil, mineral ores and rocks, in any situation where the material can be unloaded by tipping sideways from the vehicle.
The vehicle may vary from small trailers, body trucks or semi-trailers through to rail cars or heavy off-road vehicles as used on mining sites.
For the purpose of this description the system is referred to generally as being fitted to a semi-trailer, but can be applied to trailed vehicles, such as in what are commonly termed 'road trains'.
Description of the Prior Art
U.K. Patent 2106049 shows a tipping vehicle in which the body may be tipped in any one of three directions with releasable latch means to allow the desired tipping.
SU1230887 shows a tipping and lifting arrangement where the bin can be lifted from the vehicle and placed on the ground, or can be moved sideways from the vehicle and then tipped to empty.
Brief Statement of the Invention
There is provided according to the invention a side tipper support system for a side tipping bulk transport vehicle, said system comprising a chassis for the vehicle, a bulk carrying body on the chassis, said body being pivoted by pivot means to one side of the chassis, hydraulic means acting between the body and the chassis on the other side of the chassis, and support means between said body and said chassis in the transport position.
Brief Description of the Drawings
FIG. 1 shows an end elevation from the front of the vehicle, the rest position shown in full lines, a partial tip in dash lines, and a full tip in dotted lines. FIG. 1 (a) shows a section of the chassis beam in plan and FIG. 2 shows a side elevation of the vehicle.
Description of the Preferred Embodiment
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 lightweight materials such as aluminium as well as steel, plastics and composites. A major weight and cost saving is achieved by the elimination of the door, hinges and associated hydraulic mechanism which would otherwise be required.
The one piece construction and rounded shape of the body makes it rigid enough to be self-supporting when loaded thus allowing the use of a lighter chassis section than would normally be possible. A further advantage of the self-supporting body is that the hoists 2 for tipping can be mounted externally on the end of the body eliminating the need for hoist towers protruding into the load space. Another major advantage of the rounded shape 14 of the body is the tipping action. By building a straight side slope 15 into the tipping side of the body, and then rotating it, the required tipping angle 3 can be achieved to discharge the material over the side of the body. The side slope 15 extends from adjacent the hinge 6 upwardly and outwardly toward the top of the body, and the rounded shape 14 extends from the hinge 6, across the body and up to the top of the body on the opposite side to the side slope 15. The shape also produces a tumbling action in the discharge material which rolls out progressively from the top of the load instead of sliding. This action almost eliminates wear of the body shell. The chassis beam on each side of the vehicle has been designed for use with the semi-trailer use of the invention. It consists of two high tensile flanges 4 supported by a corrugated web section 5. The web section provides for ease of construction with the corrugations holding the beam square during welding and the completed beam being strong and flexible.
The hinge 6 fitted to the body is mounted on a spring loaded vertical slide 7. As shown in FIG. 2 there can be three hinges along the side of the body. The sliding action of the hinge allows the load to be lifted off the hinge when the body is resting on the chassis and reapplied to the hinge only during tipping. The hinge action acting only as a locating device while travelling. The body has feet 13 on each side which engage the flanges 4 of the beams, thus supporting the load and 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 acting, power beyond valve system which allows trailers to be 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 at one trailer it is passed on through the valve to the next, and so on. At the rear trailer a loop of hose is connected to return the oil supply to the tank via a single return line which 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 is diverted to the hoists of that trailer. The first stage of the hoists is single acting and simply lifts the body, the second stage is double acting and comes into action at position 8 before the body reaches balance point. The counter balance valve fitted to the return port of the control valve works with the second stage. This valve prevents oil exiting the return stage of the hoist unless there is positive pressure in the lift stage. The system prevents the hoist from extending out of control once the loaded passes balance point.
The body once emptied is retrieved by reversing the control valve which then applies pressure to the return side of the hoists. Once the second side is fully retracted the body is again over balance point and will return under its own weight. For side tipping semi-trailers the skid plate 9 tends to lift away from the quick release turntable 10 on the opposite side to the tipping side when tipping resulting in damage to the king pin and turntable jaws. To overcome this 5. problem a permanently mounted ball-race turntable may be used, or if a quick release facility is required a unique locking system has been designed to relieve the- lifting load on the turntable. This device consists of an arrangement 11' mounted to the turntable base which engages a semi-circular attachment 12 welded under the skid plate locking down the side subject to 0 lifting thus preventing damage to the king pin or jaws. The hook has sufficient clearance to freely engage when the turntable is coupled and tracks around the upper attachment when slewing.
By fitting hinges on both sides of the symmetrical body and mounting slightly 5 larger hoists centrally tipping to either side can be achieved simply by disengaging the hinge pins on the side to be lifted.
AlthoughOne form of the invention has been described in some detail it is to be realised that .the invention is not to be limited thereto but can include various 0 modifications falling within the spirit and scope of the invention.
