Adjustable stops for rolloff truck
A system for optimizing the load position for a container loaded onto a rolloff truck which has two side rails is effected by means of a number of pockets on each side rail. Removable stop assemblies are inserted into a corresponding pocket on each side rail. The container is then pulled up by means of a cable winch, until the container fits against the stops located on each rail. Sufficient tension is maintained on the cable so that the container cannot slide or otherwise move off the selected position, in which the load is equally distributed between the front and rear wheels.
What is claimed is:
1. An adjustable stop system for a rolloff truck, the rolloff truck comprising two frame rails, the system comprising: (a) a multiplicity of pockets, each in the form of ahollow parallelepiped, affixed in each of the frame rails; (b) a removable stop assembly insertable in the pocket on each frame rail; (c) means for retaining a container against the stop assemblies, so that the container may be disposed on the rollofftruck in one of a number of different positions.
2. The adjustable stop system of claim 1 wherein each stop further comprises: a. a lower body which extends within one of the pockets; b. a forward flange and a rear flange that prevent the adjustable stop from falling through the pocket; c.a semi-circular cutout formed above the forward flange, and which mates with a roller affixed to a front of the container.
3. The adjustable stop system of claim 2 wherein the pockets are affixed to the frame rail by welding.
4. The adjustable stop system of claim 3 wherein each pocket is affixed to the frame rail so that said pocket does not extend either above or below said frame rail.
5. The adjustable stop system of claim 1 wherein the pockets are affixed to the frame rail by welding.
6. The adjustable stop system of claim 5 wherein each pocket is affixed to the frame rail so that said pocket does not extend either above or below said frame rail.
7. The adjustable stop system of claim 1 wherein each pocket is affixed to the frame rail so that said pocket does not extend either above or below said frame rail.
8. An adjustable stop system for loading a container onto a rolloff truck which comprises a left and a right frame rail, each of the same length, spaced apart, and disposed longitudinally on the truck, the system comprising: a) a multiplicityof pockets affixed in pairs on the frame rails, one of each pair on the left rail and the other on the right rail, and each one of a pair located at about the same distance from a back end of the corresponding rail; b) a removable stop assemblyinsertable into each of the pockets; c) means for drawing the container longitudinally onto the rails and against a pair of the stop assemblies inserted into a pair of the stop pockets; and d) means for retaining the container against the stopassemblies, so that the container may be securely disposed on the rolloff truck rails at one of a number of different positions.
9. The adjustable stop system of claim 8 wherein each stop further comprises: (a) a lower body which extends within one of the pockets; (b) a forward flange and a rear flange that prevent the adjustable stop from falling through the pocket; and (c) a semi-circular cutout formed above the forward flange, and which mates with a roller affixed to a front of the container.
10. The adjustable stop system of claim 9 wherein the pockets are affixed to the frame rail by welding.
11. A method for loading a container onto a rolloff truck which comprises a left and a right frame rail, each of the same length, spaced apart, and disposed longitudinally on the truck, the method comprising: a) affixing multiplicity of pocketsin pairs on the frame rails, one of each pair on the left rail and the other on the right rail, and each one of the pair located at about the same distance from a back end of the corresponding rail; b) inserting a pair of removable stop assemblies intoone or more pairs of pockets; c) drawing the container longitudinally onto the rails and against the pair of the stop assemblies; and d) leaving the container drawn against the stop assemblies while transporting the container, so that the container issecurely disposed on the rolloff truck rails at one of a number of different positions.
12. The method of claim 11 wherein each stop further comprises: (a) a lower body which extends within one of the pockets; (b) a forward flange and a rear flange that prevent the adjustable stop from falling through the pocket; and (c) asemi-circular cutout formed above the forward flange, and which mates with a roller affixed to a front of the container.
13. The method of claim 12, further comprising affixing the pockets to the frame rail by welding.
14. An adjustable stop system for loading a container onto a rolloff truck which comprises a left and a right frame rail, each of the same length, spaced apart, and disposed longitudinally on the truck, the system comprising: e) a multiplicityof pockets inserted in pairs into the frame rails, one of each pair on the left rail and the other on the right rail, and each one of a pair located at about the same distance from a back end of the corresponding rail; f) a removable stop assemblyinsertable into each of the pockets; g) means for drawing the container longitudinally onto the rails and against a pair of the stop assemblies inserted into a pair of the stop pockets; and h) means for retaining the container against the stopassemblies, so that the container may be disposed on the rolloff truck rails at one of a number of different positions.
15. The adjustable stop system of claim 14 wherein each stop further comprises: (a) a lower body which extends within one of the pockets; (b) a forward flange and a rear flange that prevent the adjustable stop from falling through the pocket; and (c) a semi-circular cutout formed above the forward flange, and which mates with a roller affixed to a front of the container.
16. The adjustable stop system of claim 15 wherein the pockets are affixed to the frame rail by welding.
