(VIDEO) Liebherr modernizes a 23-year-old duty cycle crawler crane

Liebherr in Hong Kong is modernizing Liebherr duty cycle cranes for China Geo-Engineering Corporation. One 23-year-old machine has been transformed and given an upgrade in the process. Liebherr Transform, the upgrade, modification, and overhaul service, has a custom solution for equipment needs and is available for crawler cranes (up to 400 tonnes), deep foundation equipment, and duty cycle crawler cranes.

Liebherr says that Transform provides solutions in response to the continuously growing demands of today's businesses. A range of upgrades, retrofits, overhauls, and service modifications breathe new life into existing machines. Using the latest technology and years of experience, Liebherr utilizes a combination of sustainable and smart technologies, ideal productivity, and cost-effectiveness.

China Geo-Engineering Corporation in Hong Kong has taken advantage of the Liebherr Transform service and ordered a complete overhaul of their 23-year-old  HS 873 HD Liebherr duty cycle crawler crane. This is just one in a series of their fleet of duty cycle crawler cranes to be overhauled at Liebherr in Hong Kong – all of which are over 20 years old.

The HS 873 HD was found to be structurally sound so China Geo-Engineering decided to incorporate an upgrade in the process. "We only needed modest investments for an overhaul to get the machine working again. Consequently, we decided to upgrade its engine, from 480 kW to 605 kW and installed a second slewing gear," explains German Leung, general manager of the foundations department at China Geo-Engineering Corporation. "Basically, all our machines – HS 873 HD, HS 883 HD, and HS 853 HD – are being sent to Liebherr one by one for overhaul so they will function like new."

The incorporated repair and maintenance workshop at Liebherr (HKG) Limited added to the convenience of the project as all work could be carried out in one location. All processes relating to the dismantling, reconditioning, and assembly of the machine were carried out by Liebherr's staff on site. The Liebherr team of experts takes care of the entire planning and implementation of Transform projects – from consultation to installation and technical support and service.

Companies are under pressure to increase volume and performance, widen scopes, or reduce emissions and costs. Liebherr Transform helps to lighten the load through a range of structural, electrical, mechanical, ergonomic, or digital modifications.
