The first two Potain Hup self-erecting cranes in Australia have been delivered to Active Crane Hire of New South Wales and immediately put to work on a residential development project in the Sydney suburb of Ryde.
The cranes are assisting in the construction of a seven-storey apartment building and were chosen for their compact footprints and versatile configuration options, which make them ideal for such urban, low-rise construction projects.
Active Crane Hire managing director Hermann Buchberger said the design of the Hup 32-27, and particularly its flexible mast system, would enable the company to use the crane in a variety of scenarios on the job site.
The crane features an adjustable two-section mast with a third section within the second. This allows the third mast section to be telescoped out, boosting its working height to 27 metres.
“Unlike most cranes used for low-rise construction, the Hup 32-27 has a 27 metre working height, meaning it fits above the local tree line, which tends to be around 21 metres,” he explained. “It’s also compact enough that if we need to install it underneath a tower crane on an existing site, we can do that. This eliminates the need to rearrange cranes on site.”
The Hup 32-37 has a maximum capacity of 4 tonnes, and can lift 1 tonne at its jib end of 32 metres. It has a rear-slewing radius of only 2.25 metres, enabling it to be positioned closer to buildings.
Despite being taller than the Igo 36, one of its predecessor models, the Hup 32-27 occupies the same footprint, making it ideal for space-restricted job sites. Its two footprint options, 4 metre x 4 metre or 3.5 metre x 4.42 metre, and an innovative unfolding movement mean the crane can set up in even the most congested spaces.
The Hup 32-27 debuted in mid-2016 and has already begun popping up on job sites around the world. The goal of the Hup design is to deliver improved versatility and agility to customers, which helps them increase their return on investment. In particular, the crane’s wide variety of configurations and ease of erection help achieve this.
Three raised positions of the luffing jib, at 10, 20 or 30 degrees, in addition to horizontal, provide unprecedented options for a self-erecting crane. To maximise operator efficiency, the crane has a new radio remote control with a large colour screen and easy-to-use navigation (via jog dial). New Smart Set Up software displays unique and simple on-screen, step-by-step information during erection.
“The Hup fills a gap between large self-erecting cranes and small tower cranes. It is small and flexible enough to handle construction work for four-storey to seven-storey developments,” Hermann Buchberger explained. “It’s more user-friendly than the alternatives and the commissioning is faster, which saves us time and money.”
Active Crane Hire is a Potain business partner, based in Somersby, NSW. It is one of the largest tower crane rental companies in Australia, with a fleet of both top-slewing tower cranes and self-erecting cranes.
