ABSTRACT:
A trailer-mounted crane apparatus includes a trailer supported from a ground surface on at least two wheels. A hydraulically operated crane arm is mounted to the trailer and is extendable outwardly. A crane hydraulic power unit is mounted to the trailer and supplies pressurized hydraulic fluid to the crane arm. A vibrational sheet piling driver can be supported by the crane arm. A vibrational hydraulic power unit for supplying power to the driver is mounted on the trailer. A control panel for the crane hydraulic power unit and the vibrational driver hydraulic power unit, and an associated operator's seat, are also mounted on the trailer. The crane apparatus includes wide tires for reducing the surface pressure under the apparatus. This allows the apparatus to be transported across and used on delicate surfaces such as golf course greens and other groomed surfaces.
