Liebherr launches HS 8300 HD hybrid crawler crane

Liebherr improves the duty cycle of its 300-tonne-class HS 8300 HD crawler crane with what it calls a Pactronic hybrid drive. The system stores excess energy by charging hydraulic accumulators and regenerates it during high-demand effort to expand the machine's capability and reduce fuel consumption. The system allows the 972-hp diesel engine to achieve hoisting power of 1,073 hp and system power comparable to a conventional 1,676-hp drive system.

• Reduced fuel consumption
• Reduced noise
• Increased hoisting and lowering power
• Boom length: 224 ft. 5 in.
• Hydraulic free-fall winches: 50 tonnes of line pull
