PANORAMA

Simple demolition job with complicationsFrance
Simple demolition job with complications

Productivity was key for an excavator operating on a complex demolition project in Lyon, France, where work goes on throughout the night. The excavaotr chosen for the job was a Hitachi ZX350LC-3 which is working in Lyon Part Dieu, in the district of La Villette, France, where it is demolishing a six-story building. Much of the work needs to take place during hours of darkness, as the site is close to tramlines and there is heavy road traffic in the area.

The project is being undertaken by EBM, part of the Vinci Group, which specialises in public works.

The company selected the ZX350LC-3 for its versatility, in that it can be equipped for either demolition or earthmoving. The Zaxis medium excavator has a 21 m demolition arm and its hydraulic system works with biolubricants, which are less damaging to the environment.

The excavator was supplied by Teramat, the Hitachi dealer which serves the Rhone Alps region

Crawler and all-terrain cranes helped build parking structureUSA
Crawler and all-terrain cranes helped build parking structure

A Manitowoc 2250 crawler crane and a Grove GMK6250L all-terrain crane helped construct a two-storey underground parking structure at a mixed-use apartment complex in Bloomington, USA

The cranes were rented from Vic’s Crane and Heavy Haul by Hanson Structural Precast, the precast subcontractor working for general contractor Frana Companies. The two cranes lifted and placed the precast concrete wall panels and flooring sections. The heaviest load, a 18 m (60 ft) “double T” floor section, weighed 29,500 kg (65,000 lbs). The load-bearing walls each weighed 17,236 kg (38,000 lbs).

Tim Harty, vice president of Vic’s Crane and Heavy Haul, said “The 2250 was a great fit for our jobsite. Between the sandy ground and space constraints of the below-grade site, we only had a small runway of space to assemble the crane. The crane had to be 105 ft (32 m) from where we placed the concrete sections. As a result, we needed a crane with ample reach and capacity.”

The all-terrain crane placed the precast wall sections directly from the trucks and into position as load-bearing walls. With the perimeter walls complete, the Manitowoc 2250 crawler crane was used to place the heavier flooring slabs and the interior walls. To ensure the trucks could access the jobsite while keeping the crane on steady ground, the 2250 was assembled with Series 3 counterweights and 64 m (210 ft) of main boom.
