Abstract
A trailer for moving large oblong objects, which objects are normally oriented so that the longer length is oriented vertically, notably as in oil storage tanks located at well sites. The trailer comprises a load bed which tips into a vertical position adjacent the object. When the load bed is in the vertical position, the rear end of the load bed contacts the ground and lift plates attached to the rear end of the load bed extend along the ground. The trailer is then backed up against the object and the lift plates slide under the object. One or more arms are activated to clamp the object against the bed, allowing it to be lowered with the bed to a horizontal position for transport.

2 Normal oil field operations require that these tanks often be moved from oz~e location to another.
Present methods for transporting them are slow and hazardous for the personnel involved. A
load bed is raised to a vertical position adjacent to the tank and the tank is then secured to the load bed by chains or straps at the top and bottom. This involves climbing to the top of the tank, oftf~n some 30 feet in the air, to secure chains. Not only is the climb hazardous, but often the top of the tank is rusted from exposure to the elements and thereby weakened, making walking on the top dangerous as well.
In ;some areas safety authorities do not allow persons to climb on the tanks to secure chains, requiring instead that a picker truck accompany the trailer truck to raise a person safely to the top to secure the chains.
The; present procedure is time consuming as well as hazardous.

6 X111 hydraulically activated cylinders, beinb the load cylinder lU, the swinb cylinder 16, the starter lift cylinder 21 azld the final lift cylinders 22, are conventionally powered and controlled by hydraulic pumps and valves connected by hydraulic fluid lines, none of which are shown in the drawings.
Tn operation, the trailer is backed up t:o a tank 15 to be moved. Starter lift cylinder 21 is fully extended, raising the load bed C from the horizontal frame l, pivoting about load bed hinge 7.
7vhen final lift cylinders 23 are extended , raising the load bed 6 into the vertical position as shown in Figure 2. As the load bed 6 pivots about the load bed hinge 7, the rear end of the load E,ed 6 contacts the ground 25, and when the load bed 6 reaches the vertical position, the weight of the trailer rests on the rear end of the load bed 9 and the lift plates 8.
Depending on the suspension of the trailer, the wheels 4 may be raised off the ground 25. At this point, the txailer is backed against the tank 1.5. The lift, plates 8 slide along the ground 25 and under the tank 15.
Load cylinder 10 and swing cylinder 16 are activated to bring th.e Ioad clamp plate 13 into c:ontaet with the upper end of the tank 1 S, which thereby exerts a force on the tank 15 in the direction of the load bed 6, and holds t:~e tank in position against the load bed 6.
Final lift cylinders 23 are then retracte,cl., lowering the load bed (i and the tank 15 held by the load clamp plate 13, to rest on the fully extended starter lift cylinder 21.
Starter lift cylinder 2.1 is then retracted, lowering the load bed G to rest on the horizontal frame 1. As the load bed 6 pivots <iown about load bed hinge 7, the weight of the trailer is tr~,nsfcrrcd to the horizontal fra»~e 1, a,nd wheels 4 return to rest on the ground 25. The load bed 6 and tank 1 S are then secured to the horizontal frame by chains or other conventional xzz.eans prior to transport.
