Tadano HK70

The Tadano HK 70 is a high-performance 70-ton truck-mounted crane, built by integrating the superstructure of the ATF65G onto a commercial 4- or 5-axle carrier chassis. This configuration allows for efficient road mobility and reliable crane operation. The crane was notably co-developed in collaboration with Mammoet, the world’s largest crane rental company, which took delivery of 25 units in late 2009—15 units on 4-axle and 10 units on 5-axle trucks—marking the crane’s introduction in the UK.

At the heart of the crane is a 5-section telescopic boom with a working range of 11.0 m to 44.0 m, made of high-tensile steel and telescopable under partial load. For greater flexibility, the HK 70 can be fitted with a boom extension of 9.0 m or 16.0 m, which is manually offsettable at 0°, 20°, and 40°, bringing the total reach to approximately 60.0 m.

The crane is powered by a Mercedes-Benz OM904LA 4-cylinder diesel engine (Euromot IIIA / EPA Tier 3), producing 90 kW (122 hp) at 2200 rpm, with a torque of 470 Nm. The engine drives a three-circuit hydraulic system with axial piston and gear pumps, enabling simultaneous, independent crane functions. Hydraulic outriggers provide a maximum spread of 6.5 m longitudinally and 6.3 m transversely, ensuring solid stability during lifting.

The slewing system delivers 360° continuous rotation at up to 2 rpm, while the main hoist offers a maximum line pull of 44 kN and speeds up to 130 m/min. The main winch includes a spring-loaded hydraulic multiple-disc brake and “Super-Stop” rope management system. The derrick system uses a differential cylinder with built-in brake and holding valve for controlled boom elevation.

Control is through two electronic joystick levers, giving the operator smooth, responsive multi-function operation. The crane’s counterweight totals approx. 15.2 t, hydraulically installed and removable from the superstructure cab.

The superstructure cab is ergonomically designed, featuring panoramic safety glazing, tiltable operator seat, air conditioning, and an engine-independent heater with preheat capability. Electrical systems operate on a 24V circuit with two batteries.

Safety features include a Load Moment Device (LMD), hoist and swing limiters, working area limiter, winch drum rotation indicator, hydraulic safety valves, and anti-drop systems. Optional equipment includes additional boom extensions, hook blocks, auxiliary winches, custom paint, and Tadano’s ‘Lift Adjuster’ system.

With its mix of road-friendly transport, crane-grade lifting, and smart control, the Tadano HK 70 is ideal for a range of applications, including regional construction, urban infrastructure, and utility work where mobility and performance must go hand-in-hand.
