Abstract
An apparatus for increasing the vertical travel of auxiliary wheels mounted on an auxiliary axle includes a lever rotatably mounted on the auxiliary axle and a wheel mounting spindle secured to the lever spaced from its mounting on the auxiliary axle to displace the wheel from the axle. In a preferred form of the invention, the lever is mounted on the axle by being secured to the end of a second axle rotatably mounted within the hollow auxiliary axle. Apparatus is provided to cause rotation of the lever between a lowered position in which the auxiliary wheels can be moved into weight bearing position and a raised, increased clearance position. A lock is provided so the lever can be locked in position, at least when in lowered position. In some cases, the lever will be mounted to the axle in a manner to allow the auxiliary wheel to caster and thereby steer with the vehicle on which it is mounted.
