ABSTRACT:
A self-contained amusement ride designed for use on a mobile unit can be folded into a compact assembly for highway transport. During operation of the ride, an angularly off-set undercarriage allows the front portion of the mobile unit to support the entire weight of the ride on the ground with essentially no weight on the rear wheels. A pivoted kingpin plate allows transport with adequate ground clearance and a retractable landing gear on the front end of the mobile unit provides for raising and lowering the mobile unit for connection and disconnection from a prime mover. Hydraulically assisted lockable supports tie the main sweep arms to the mobile unit during transit.
Pins with integral sliding hammers are provided to perform certain locking and pinning functions during assembly and disassembly of the ride. A single cylinder operates to pivot the top part of the main mast into and out of its support position and simultaneously raise and lower the lighting units on counterbalanced and spring biased linkages between the main mast and the unit masts. The ride incorporates three radially oriented units that rotate in one direction around the main mast, each radial unit carries four balanced seats that rotate in the opposite direction, around their unit masts. The folding, unfolding and locking of the seat sweeps is assisted by geometrically oriented and linked tie rods. The ride includes its own hydraulic operating circuit and set-up circuit.
