DETAILED DESCRIPTION
A trailer as shown in the drawings comprises a main frame generally indicated at 10 carried on ground wheels 11 including an axle 12 attached to the frame by suitable suspension arrangement (not shown). The main frame includes a pair of longitudinal beams 13, 14 and a main transverse rear beam 15. The main frame is covered by a main decking 16 on which an 20 object to be transported is located.
At the transverse beam 15 is mounted a support frame 17 having a pair of depending side struts 18 and 19 and a horizontal bottom rail 20. The frame 17 as shown includes a top rail 21 but this may comprise simply a part of the beam 15. The rail 21 includes a pair of rearwardly extending lugs 22 25 and 23, each at a respective end of the rail 21 that is at a respective side of CA 0221618~ 1997-09-17 the trailer. The frame 17 is supported relative to the main longitudinal beams 13 and 14 by braces 23.
The pivotal deck portion 25 comprises a pair of main longitudinal beams 26 and 27 and a pair of cross beams 28 and 29 forming a rigid rectangular structure. On top of the beams 26 and 27 is provided a decking 28 which in the raised position shown in Figure 1 is coplanar with the decking 16 for supporting the object.
At a forward end of each of the beams 26 is provided a respective lug 31, 32 which cooperates with a respective one of the lugs 22, 23 and is 10 connected thereto by a pivot pin 33 allowing pivotal movement of the deck portion 25 about a horizontal axis 34 defined by the pins 33. The deck portion 25 can therefore move to the second position shown in Figure 2 in which it is inclined downwardly and rearwardly from the edge of the trailer defined by the rail 21 with a chamfered end 35 of the beams 26 and 27 in engagement with 15 the ground.
An actuating mechanism for effecting a movement between the first and second positions is generally indicated at 40. The actuating mechanism comprises a strut 41, a linear actuator 42 in the form of a hydraulic cylinder, a hinge rod 43 and a stop member 44.
As shown in Figure 3, two such actuating mechanisms are shown each at a respective side of the deck portion. In some lighter structures, a single actuating mechanism may be used. However it is generally preferred that two such actuating mechanisms are used as shown in Figure 3 since this provides symmetrical movement and reduces the possibility of twist of the deck CA 0221618~ 1997-09-17 portion as it raised in a situation where the load is unevenly balanced. As the actuating mechanisms are identical, only one will be described in detail.
The strut 41 has a first end 50 pivotally connected to the rail 20 by a lug 51 mounted on a rearwardly facing surface of the rail 20. A pin 52 connects the end 50 to a lug 51 for pivotal movement about an axis 53 below the axis 34.
A second end 54 of the strut 41 is connected to the deck portion at a lùg 55 by a pin 56 defining an axis 57 spaced outwardly from the axis 34.
The strut 4i is divided into a first strut portion 60 and a second 10 strut portion 61. The strut portion 60 extends from the end 50 to the hinge rod 43. The second strut portion 61 extends from the end 54 to the hinge rod 43. Both the first and second portions are mounted on the hinge rod for pivotal movement relative thereto about an axis 64 of the hinge rod. Thus the strut 41 is substantially straight in the first position of Figure 1 and is folded 15 about the axis 64 in the second position of Figure 2.
Movement between these positions is effected by the cylinder 42.
The cylinder 42 is attached to a lug 63 on the beam 28. A piston rod 64 of the cylinder 32 has a rod coupling 65 attached to the hinge pin 43 for actuating movement of the hinge pin forwardly and rearwardly to provide the 20 straightening and folding action of the strut.
In the embodiment shown, the hinge pin 43 extends across the full width of the deck portion so as to interconnect the two actuating mechanisms, but this is not necessary. In the embodiment shown, the coupling 65 of the cylinder 42 is connected to the hinge pin but again this is not necessary. It is25 possible for the coupling of the cylinder to be attached directly to one or other CA 0221618~ 1997-09-17 of the strut portions but it is preferred that the coupling be at or adjacent the hinge pin in order to provide the best mechanical advantage. The strut portion 61 is significantly shorter than the strut portion 60. In this way the cylinder acts in a direction substantially parallel to the undersurface of the decking of5 the deck portion. Also the length of the second strut portion 61 is such that its end 66 at the hinge pin 43 does not project below the end 35 of the beam 26 at the ground so as to avoid interfering with the movement to the ground.
The stop 44 comprises a body which extends downwardly from the undersurface of the beam 26. The body defines a shoulder 67 for engaging 10 a top surface 68 of the second strut portion 61 when in the first position asshown in Figure 1. The stop body further includes a portion 70 which extends beyond the shoulder 44 having a surface 72 over which a side of the strut portion 61 slides when moving to the first position. The portion 70 includes a hole 73 for receiving a pin 74 as shown in Figure 1. The pin 74 extends 15 through the hole 73 generally parallel to the shoulder 67 so as to lock the strut portion 61 in position on the stop member. The locking action prevents upper movement of the strut portion 61 by the shoulder 67 and prevents downward movement of the strut portion 61 by the pin 74. This stop member acts to prevent any possibility of the strut moving out of the first position of Figure 1 20 even in event of failure of the cylinder 42.
In the first raised position of Figure 1, the strut 41 is slightly over center so that the application of weight to the decking of the deck portion tends to push the hinge pin upwardly thus pressing the strut portion 61 against the shoulder 67.
CA 0221618~ 1997-09-17 Movement to the second position is effected by actuating outward movement of the cylinder thus pushing the hinge pin outwardly and folding the strut until the end 35 engages the ground. Reverse movement from the second incline position of Figure 2 is effected simply by pulling the cylinder inwardly5 thus pulling the hinge pin inwardly. This action has significant mechanical advantage thus allowing the deck portion to lift significant loads.
Since various modifications can be made in my invention as herein above described, and many apparently widely different embodiments of same made within the spirit and scope of the claims without departing from such 10 spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.

DETAILED DESCRIPTION
A trailer as shown in the drawings comprises a main frame generally indicated at 10 carried on ground wheels 11 including an axle 12 attached to the frame by suitable suspension arrangement (not shown). The main frame includes a pair of longitudinal beams 13, 14 and a main transverse rear beam 15. The main frame is covered by a main decking 16 on which an 20 object to be transported is located.
At the transverse beam 15 is mounted a support frame 17 having a pair of depending side struts 18 and 19 and a horizontal bottom rail 20. The frame 17 as shown includes a top rail 21 but this may comprise simply a part of the beam 15. The rail 21 includes a pair of rearwardly extending lugs 22 25 and 23, each at a respective end of the rail 21 that is at a respective side of CA 0221618~ 1997-09-17 the trailer. The frame 17 is supported relative to the main longitudinal beams 13 and 14 by braces 23.
The pivotal deck portion 25 comprises a pair of main longitudinal beams 26 and 27 and a pair of cross beams 28 and 29 forming a rigid rectangular structure. On top of the beams 26 and 27 is provided a decking 28 which in the raised position shown in Figure 1 is coplanar with the decking 16 for supporting the object.
At a forward end of each of the beams 26 is provided a respective lug 31, 32 which cooperates with a respective one of the lugs 22, 23 and is 10 connected thereto by a pivot pin 33 allowing pivotal movement of the deck portion 25 about a horizontal axis 34 defined by the pins 33. The deck portion 25 can therefore move to the second position shown in Figure 2 in which it is inclined downwardly and rearwardly from the edge of the trailer defined by the rail 21 with a chamfered end 35 of the beams 26 and 27 in engagement with 15 the ground.
An actuating mechanism for effecting a movement between the first and second positions is generally indicated at 40. The actuating mechanism comprises a strut 41, a linear actuator 42 in the form of a hydraulic cylinder, a hinge rod 43 and a stop member 44.
As shown in Figure 3, two such actuating mechanisms are shown each at a respective side of the deck portion. In some lighter structures, a single actuating mechanism may be used. However it is generally preferred that two such actuating mechanisms are used as shown in Figure 3 since this provides symmetrical movement and reduces the possibility of twist of the deck CA 0221618~ 1997-09-17 portion as it raised in a situation where the load is unevenly balanced. As the actuating mechanisms are identical, only one will be described in detail.
The strut 41 has a first end 50 pivotally connected to the rail 20 by a lug 51 mounted on a rearwardly facing surface of the rail 20. A pin 52 connects the end 50 to a lug 51 for pivotal movement about an axis 53 below the axis 34.
A second end 54 of the strut 41 is connected to the deck portion at a lùg 55 by a pin 56 defining an axis 57 spaced outwardly from the axis 34.
The strut 4i is divided into a first strut portion 60 and a second 10 strut portion 61. The strut portion 60 extends from the end 50 to the hinge rod 43. The second strut portion 61 extends from the end 54 to the hinge rod 43. Both the first and second portions are mounted on the hinge rod for pivotal movement relative thereto about an axis 64 of the hinge rod. Thus the strut 41 is substantially straight in the first position of Figure 1 and is folded 15 about the axis 64 in the second position of Figure 2.
Movement between these positions is effected by the cylinder 42.
The cylinder 42 is attached to a lug 63 on the beam 28. A piston rod 64 of the cylinder 32 has a rod coupling 65 attached to the hinge pin 43 for actuating movement of the hinge pin forwardly and rearwardly to provide the 20 straightening and folding action of the strut.
In the embodiment shown, the hinge pin 43 extends across the full width of the deck portion so as to interconnect the two actuating mechanisms, but this is not necessary. In the embodiment shown, the coupling 65 of the cylinder 42 is connected to the hinge pin but again this is not necessary.

Also the length of the second strut portion 61 is such that its end 66 at the hinge pin 43 does not project below the end 35 of the beam 26 at the ground so as to avoid interfering with the movement to the ground.
The stop 44 comprises a body which extends downwardly from the undersurface of the beam 26. The body defines a shoulder 67 for engaging 10 a top surface 68 of the second strut portion 61 when in the first position asshown in Figure 1. The stop body further includes a portion 70 which extends beyond the shoulder 44 having a surface 72 over which a side of the strut portion 61 slides when moving to the first position. The portion 70 includes a hole 73 for receiving a pin 74 as shown in Figure 1. The pin 74 extends 15 through the hole 73 generally parallel to the shoulder 67 so as to lock the strut portion 61 in position on the stop member. The locking action prevents upper movement of the strut portion 61 by the shoulder 67 and prevents downward movement of the strut portion 61 by the pin 74. This stop member acts to prevent any possibility of the strut moving out of the first position of Figure 1 20 even in event of failure of the cylinder 42.
In the first raised position of Figure 1, the strut 41 is slightly over center so that the application of weight to the decking of the deck portion tends to push the hinge pin upwardly thus pressing the strut portion 61 against the shoulder 67.
CA 0221618~ 1997-09-17 Movement to the second position is effected by actuating outward movement of the cylinder thus pushing the hinge pin outwardly and folding the strut until the end 35 engages the ground.
