Civil and industrial contractor Perico Renato Construzioni Edili has used a Genie ZX 135/70 boom lift to perform maintenance works on a disused water tower located in Novagli di Montichiari in Brescia, Italy.
The project saw Perico carry out the safety works to the tower’s concrete roof structure to prevent debris from its slabs falling off after suffering years of weather damage.
The company, which was contracted by environmental services and heating company A2A, selected the Genie ZX 135/70 for the job with input from specialists at rental company Elevo – Kiloutou. The model features a working height of 43.1m (141 ft), an outreach of just over 18m (59ft) and a maximum up and over height of more than 23m (75ft). Equipped with a 280kg (600lb) capacity basket, the ZX 135/70 has a turret capable of rotating a full 360° continuous rotation turret, four-wheel drive and steering.
Prior to starting the maintenance works, Perico undertook surveys of the aqueduct and used drone video recordings and photographs as part of its risk assessment and planning procedure. It also carried out an evaluation of the site’s terrain and built two 20-tonne reinforced concrete stalls over an area of 128m2 (1,377sqft) to ensure the Genie boom could reach every point of the water tower.
Renato Poloni, Perico Renato’s surveyor, said, “We had to start with the design of both the method of securing the cap and, in collaboration with Elevo’s technicians, the planialtimetric positioning of the platform, paying close attention to all safety aspects, such as accessibility to the workplace, suspended power lines, adjacent geometric impediments, soil bearing capacity, underground installations, etc. etc.”
He continues, “We then proceeded with the design, manufacturing and installation of a safety net coupled with an anti-debris net, both with a diameter of 15m (49ft 2.5in) and weighing more than 60kg (132lb). This was laid out, pulled up to the edges of the “hat” and then integrated with a one-meter wide band, sewn with special rope, along the entire perimeter.”
The maintenance works took two days complete with a total of five technicians, one in the basket and four on the top of the structure, working at a height of 40 m (131 ft). The group of technicians, which included A2A personnel and rigging and safety professionals.
