Abstract
A system for leveling a personnel carrying platform mounted on the end of an elongated vehicle mounted boom. A pendulum controlled hydraulic valve controls the application of fluid pressure to a pair of cylinders equipped on their ends with a series of links extending along a drum connected to the platform mounting pin. When the platform deviates from a level position, one of the cylinders is retracted to turn the platform mounting pin in a direction to correct the deviation. An interlock valve disables the platform leveling system unless the boom is being moved. A manual override valve allows the platform to be tilted for storage or other reasons.
