Manitowoc unveiled a new city crane at Intermat. The GCK3045, developed in partnership with Kobelco and to be sold under the Grove brand, is a six-wheeled crane designed to be maneuverable in tight urban sites while maintaining functionality.
Since dimensions are vital to the GCK3045’s success as a city crane, the designers kept its parameters compact so that the Grove can pass through industrial doors. It's 9.1 m (29.8 ft) long, 3 m (9.8 ft) high, and 2.6 m (8.5 ft) wide. The outriggers can be set to five different positions and also can be extended to different lengths on each side of the crane.
Lifting capabilities are no less important than dimensions, and the GCK3045 comes with the longest full-power boom in class, at 35 m (115 ft), and a capacity of 45 t (50 ton). An optional twist jib, so called because the operator twists it into place before bolting it, adds up to 10.2 m (33.5 ft) to the boom. Setup is a one-person job and can be done within the vehicles’ width.
One operator can manage the crane, and the single-person cab has a graphic display as well as hoist and rear cameras to enable the operator to see areas out of view. Air-conditioning, a PA system, and night lighting are standard. No additional counterweight is required, as the engine is used as balance in the superstructure.
A maximum tip height of 46.5 m (152.6 ft) is available from the boom, and the hook block stows automatically for travel. Once the GCK3045 is on the road, the steering system adjusts the rear-wheel steering, detects the first axle steering angle, and adjusts to minimize tire wear. Off-highway, crab, and cramp, or tight, steering settings are available.
Power comes from a Hino six-cylinder diesel developing 330 kW (443 hp). Power is sent through hydraulic pumps to the hydrostatic transmission, which also allows for efficient braking using retardation. The top speed is 85 km/h (53 mph).
