Product Description

Powered by a water-cooled 8-cylinder DaimlerChrysler diesel engine OM 502 LA, the AC140 delivers a potent 390 kW (530 HP) at 1800 rpm and a maximum torque of 2400 Nm at 1300 rpm. This engine’s performance is certified in compliance with EURO MOT 3a, Tier 3, and CARB standards, underscoring the crane’s commitment to environmental responsibility alongside power. Fuel efficiency is also a key feature, with a substantial fuel tank capacity of 500 liters.

Transmission is handled by a ZF AS-Tronic electronically automated system, providing 16 forward and 2 reverse speeds, integrated with a retarder and cruise control for enhanced driving comfort and safety. The crane’s mobility is further supported by its axles—2, 3, 4, and 5 are driven, and 1, 2, 4, and 5 are steered, featuring transverse and longitudinal differential lockout control.

For on-site maneuverability and stability, the AC140 boasts a hydro-pneumatic suspension on all axles, lockable hydraulically for precise operations. The steering system is adept, offering speed-dependent rear axle steering through a dual-circuit semiblock mechanical system with hydraulic booster, optimizing maneuverability and driving stability.

Safety and operational efficiency are prioritized with the state-of-the-art Demag IC-1 crane control system, featuring touchscreen functionality for intuitive control over the crane’s functions. This advanced system enables the operator to perform multiple tasks with precision and ease, ensuring both safety and productivity on the job site.

The AC140’s cabin is designed with operator comfort in mind, featuring a wide array of amenities including pneumatically sprung and heated seats, safety glass, electric windows, and comprehensive climate control, making it an ideal choice for prolonged operations in varying conditions.
