DESCRIPTION:

• This Manual provides information for the maintenance of the Model RT875E Series Grove Crane.
  The lift capacities are listed on the Load Chart in the cab.
• The crane incorporates an all welded parallel box construction steel frame, using planetary
  drive axles to provide four-wheel drive. Axle steering is accomplished utilizing hydraulic steer
  cylinders. The engine is mounted at the rear of the crane carrier and provides motive power through
  a six speed forward and reverse transmission.
• The carrier frame incorporates an integral fifth wheel, to which the rear axle is mounted, to
  provide axle oscillation. Axle oscillation lockout is automatic when the superstructure rotates
  from the travel position.
• The superstructure is capable of 360 degree rotation in either direction. All crane functions are
  controlled from the fully- enclosed cab mounted on the superstructure. The crane is equipped with a
  four-section, full power, sequenced and synchronized boom. Additional reach is obtained by
  utilizing an optional swingaway boom extension. Lifting is provided
  by a main hoist and an optional auxiliary hoist.
