Terex Gyro 4518 Telescopic Handler Service Repair Workshop Manual PDF VEHICLE/EQUIPMENT INTRODUCTION: The Terex Gyro 4518 telescopic handler is a close sibling to the Gyro 4020 within the Terex Gyro series of 360-degree rotating telehandlers. The 4518 designation indicated a machine with slightly higher lift capacity than the 4020, approximately 4500 kg lift capability, while offering slightly reduced but still substantial maximum boom height of approximately 18 meters. This model was configured for operations requiring higher individual lift capacity at moderate heights rather than maximum reach, making it particularly well-suited for material handling in construction supply yards, masonry installation, steel fabrication, and agricultural bulk material handling. Like all Terex Gyro series machines, the 4518 featured a full 360-degree rotating superstructure that placed the boom, cab, and counterweight on a continuously rotatable platform mounted atop a stationary or slow-moving chassis. This design paradigm eliminated the need to constantly reposition the vehicle chassis for multi-directional load placement, significantly reducing cycle times in pick-and-place applications and reducing ground disturbance on sensitive surfaces. The rotating superstructure concept was pioneered in the telehandler segment and represented a major innovation over conventional fixed-boom telehandler designs. The 4518 shared many component families with the 4020 but was tuned for different performance priorities: higher hydraulic flow to the lift circuit for faster cycle times with heavier loads, and a diesel engine calibrated for strong hydraulic power at lower RPM to maximize fuel efficiency during sustained lifting operations. The four-wheel drive chassis with selectable steering modes provided the machine with the agility needed for yard operations while the load moment indicator system ensured safe operating parameters were maintained regardless of boom angle, extension, or load weight. This manual provides complete factory-level service documentation for the Terex Gyro 4518.
