Abstract: A universal boat tower system includes an adjustment system having raceways formed in tower uprights and crossbars for receiving extensions from adapters to affix the adapters and the tower system to boat consoles and other equipment.

Abstract: The present invention relates to an aerial ladder truck to allow the height of a rear end of an extensible ladder, which is a connection end thereof connected at the rear of a bed of the truck, to be freely adjusted so that articles may be loaded in a space below the extensible ladder and above the truck bed.

Abstract: A mobile ladder support assembly provides stable lateral and rear support, and transportability for operation of a ladder. A lateral support bar restricts lateral tilting by the assembly. A pair of height adjustable rear support bars restrict backwards tilting by the assembly. A pair of caster wheels transport the assembly and the ladder. The wheels ride a pivot bar that rotates in a first direction for a stationary position. When the pivot bar is manipulated towards the second direction, the pair of wheels drop to a mobile position. Springs at the ends of the pivot bar create tension that maintains the pivot bar in the first position. Tabs selectively engage a notches to retain the wheels in the stationary position, or release the wheels to the mobile position. The free rotation and swivel of the wheels creates a center of mass that drop the wheels to the mobile position.

Abstract: A support device for a ladder. The support device comprises a first support frame coupled with the base portion and a second support frame coupled with the base portion. Each of the first and support frames comprise a top portion and a pair of elongate stiles. The first support frame and the second support frame are each pivotable relative to the base portion between a stored position and an extended position. In the extended position, the first support frame top portion is releasably connected to the second support frame top portion. The support device also comprises a tether arrangement operative to disconnect the first support frame from the second support frame such that the first and second support frames may be pivoted to the stored position.

Abstract: A portable support system for a work platform is provided which is particularly adapted for use on and around boats in order to provide safe access to the superstructure of the boat.

Abstract: A ladder support device for securing a ladder to a vehicle is described having a hitch tube suitable for being received by a receiver hitch of a vehicle. A pair of side plates are attached to the hitch tube wherein each side plate of the side plates comprises a pivot void and an upper void wherein each pivot void is arranged to align with a first hollow ladder rung of a ladder and each upper void is arranged to align with a second hollow ladder rung of the ladder. A first rod is provided which is adapted for inserting in each pivot void and the first hollow ladder rung with the first hollow ladder rung between the side plates. A second rod is provided adapted for inserting in each upper void and the second hollow ladder rung.
