Abstract
A dump truck is provided with a mooring device for maintaining a dump body of the truck in a raised position when the truck is being serviced. The mooring device utilizes two tension members or cables and includes a load distribution mechanism so as to prevent one of the tension members from carrying a substantially greater tensile load than the other member.
Claims14
A mooring device for maintaining a dump body of a truck in a raised position, said truck having a chassis with said dump body being pivotally mounted on said chassis about a transverse pivot axis for movement between a lowered position and a raised position, said mooring device comprising:
- a pair of laterally spaced apart and generally parallel tension members, each tension member being attached between one of a first set of mooring points on said chassis and one of a second set of mooring points on said dump body and each tension member being capable of carrying a high tensile load sufficient to maintain said dump body in its raised position;
- and
- a load distribution mechanism containing one of said first and second sets of mooring points, said load distribution mechanism being constructed with a capacity to accommodate a sufficient amount of dimensional variation to ensure that the tension members are equally loaded when said mooring device is being employed so as to prevent one of said tension members from carrying a substantially greater tensile load than the other tension member.
A mooring device for maintaining a dump body of a truck in a raised position, said truck having a chassis with said dump body being pivotally mounted on said chassis about a transverse pivot axis for movement between a lowered position and a raised position, said mooring device comprising:
- a first tension member capable of carrying a high tensile load and having a first free end anchored to said chassis at a left-hand location;
- a second tension member capable of carrying a high tensile load and having a first free end anchored to said chassis at a right hand location spaced laterally apart from said left-hand location;
- and
- a load distribution mechanism affixed to said dump body, said load distribution mechanism being adapted to ensure that equal tensile loads are carried by each of said first and second tension members when said mooring device is being employed to maintain said dump body in its raised position so as to prevent one of said tension members from carrying a substantially greater tensile load than the other member.
A mooring device for maintaining a dump body of a truck in a raised position, said truck having a chassis with a rear axle housing, said dump body being pivotally mounted on said chassis about a transverse pivot axis for movement between a lowered position and a raised position, said mooring device comprising:
- a first bell crank and a second bell crank, each bell crank having an apex;
- a pair of brackets attached to the underside of said dump body at transversely spaced apart locations to the rear of said dump body pivot axis, each of said brackets being adapted to pivotally mount a respective one of said bellcranks at their apexes about a pivot axis that is parallel to the pivot axis of the other bellcrank;
- a first cable having one end connected to said axle housing and a second end connected to a first lever arm of said first bell crank, said lever arm being oriented in a lateral, outwardly extending direction;
- a second cable having one end connected to said axle housing and a second end connected to a first lever arm of said second bell crank, said first lever arm of said second bell crank being oriented in a lateral, outwardly extending direction;
- and
- a third cable interconnected between an upwardly extending lever arm of each of said first and second bell cranks whereby a tensile load on said mooring device is shared equally by said first and second cables.
