A flanged link cross tube (,) for use in pivotal connections of beams (,) that locates weld roots (,) to the outer mating surface of beam (,) and flange (,). As the beams (,) rotate about a pivot connection, high torque loading occurs along the common plane (Z) between adjacent beams (,). Locating weld roots (,) on the outer mating surface of beams (,) and flanges (,) reduces loading on weld roots (,) and extends the useful life of a scissors lift (,).

Flanged cross tubes for use in scissors linkages

A trailer personnel lift (,) with a level-sensing system (,). The level-sensing system (,) provides information to a level-indicator display (,) that indicates which outriggers (,) of the trailer personnel lift (,) need to be lowered. Upon lowering of the designated outriggers (,), the signal for the outrigger (,) changes so as to indicate that the outrigger (,) no longer needs lowering. The outriggers (,) are capable of locking into at least three positions, a first position (,A) in which the outrigger (,) extends substantially horizontal to the surface upon which the personnel lift (,) is to be located, a second position (,A) in which the outrigger (,) extends substantially vertically from the base, and a third position (,A) that is intermediate of the first and second positions, the third position being selected so that the outriggers (,) may be stabilized in the third position (,A) on an upward slope.

Trailer personnel lift with a level sensor and manually set outriggers

A scissors lift (20) including an engine compartment (22) having an engine (24) therein. An engine mount (25) which permits rotation of the engine (24) outward about two pivot axes and out of the engine compartment (22) so that items on the back side of the engine such as the oil filter, alternator, or starter can be accessed. The engine (24) begins in a first position, is rotated about a first axis (68) to a second position, and is rotated outward about a second axis (70) to a third position.

Dual pivot swing-out engine tray

A trailer personnel lift (20) with a level-sensing system (69). The level-sensing system (69) provides information to a level-indicator display (72) that indicates which outriggers (34) of the trailer personnel lift (20) need to be lowered. Upon lowering of the designated outriggers (34), the signal for the outrigger (34) changes so as to indicate that the outrigger (34) no longer needs lowering. The outriggers (34) are capable of locking into at least three positions, a first position (40A) in which the outrigger (34) extends substantially horizontal to the surface upon which the personnel lift (20) is to be located, a second position (48A) in which the outrigger (34) extends substantially vertically from the base, and a third position (46A) that is intermediate of the first and second positions, the third position being selected so that the outriggers (34) may be stabilized in the third position (46A) on an upward slope.

A transport device, or hand truck (10), having a load carrying surface (26) that is mounted to move up and down along the hand truck (10). The level of the load carrying surface (26) is changed by the amount of air within a pneumatic cylinder (40). The amount of air in the pneumatic cylinder (40) is determined by a pneumatic adjustment subsystem (42) and the load on the load carrying surface (26). Preferably, the pneumatic adjustment subsystem (42) is set so that the top item located on the load carrying surface (26) is always at waist level. The pneumatic adjustment system (42) permits the pneumatic cylinder (40) to be offset an incremental amount respective to items of identical weight and height being removed from or placed upon the load carrying surface (26). Thus, as items are removed from the load carrying surface (26), the load carrying surface indexes upward so that the top item is readily available at waist level.
