Vehicle for transport and placement of grave headstones

A two-wheeled trailer type vehicle for loading, transporting and placement of grave headstones by a single workman, comprising in combination:

• a trailer having a ladder type frame supporting a bed with upstanding sides, a single transverse axle carrying rotatable wheels at each end and a forwardly extending tongue structure including a tongue beam having means for attachment to a propelling vehicle and vertically adjustable means for supporting the tongue on an underlying surface;
• an outrigger structure having an elongate symmetrical outrigger support beam carried by the trailer frame to extend laterally therefrom, said outrigger support beam slidably carrying an outrigger beam having a vertically adjustable support foot structure at one end and means for adjustable lateral positioning of the outrigger beam in the outrigger support beam,
• crane mast support structure carried on the tongue beam forwardly of the trailer bed and comprising an upstanding crane mast connecting collar extending upwardly above the upstanding sides of the trailer bed and defining a channel for journaling a crane mast connecting portion;
• a crane mast connecting portion journaled in said crane mast connecting collar for rotary motion and carrying an upstanding crane mast carrying a crane boom and a hoist having a cable supported by the crane boom;
• and
• braking structure, communicating between the crane mast connecting collar and the trailer, including
• an annular brake rotor irrotatably supported on the crane mast connecting portion spacedly above the crane mast connecting collar,
• a brake mounting plate irrotatably supported by the trailer spacedly beneath the brake rotor, said brake mounting plate having at least one upstanding friction pad extending adjacent the brake rotor,
• a brake caliper supported by the brake mounting plate for adjustable vertical positioning spacedly above the brake rotor and having at least one depending brake pad extending adjacent the brake rotor, and
• threaded means communicating between the brake mounting plate and brake caliper to adjustably move the mounting plate and brake caliper into frictional contact with the brake rotor therebetween.

In a trailer type vehicle for loading, transporting and placement of heavy objects by a single workman, of the type having a frame supporting a bed with upstanding sides, opposed wheels for locomotion and a tongue structure, the improvement comprising in combination:

• an outrigger structure having a support beam carried by the trailer frame to extend laterally therefrom and slidably carry for adjustable extension therefrom an outrigger beam having an adjustably depending foot structure,
• a rotatable crane having a mast rotatably journaled in crane mast support structure carried by the trailer and supporting an outwardly extending boom and a hoist with cable operatively depending from the outer end of the boom, and
• braking structure communicating between the crane mast and the trailer frame to adjustably regulate torque required to rotate the crane in the crane support structure, said braking structure comprising
• an annular brake rotor irrotatably supported on the crane mast supported structure,
• a brake mounting plate irrotatably supported by the trailer structure spacedly beneath the brake rotor, said brake mounting plate having at least one upstanding friction pad extending adjacent the brake rotor,
• a brake caliper supported by the brake mounting plate for adjustable vertical positioning spacedly above the brake rotor and having at least one depending brake pad extending adjacent to the brake rotor, and
• screw means communicating between the brake mounting plate and brake caliper to adjustably move the brake mounting plate and brake caliper into frictional contact with the brake rotor therebetween.
