Potain has launched the MRH 175 tower crane, a new hydraulic luffing jib crane that will make its debut at CONEXPO 2020. The MRH 175 is the latest release in Potain’s line of hydraulic luffing jib cranes, a product line the company has continuously developed since unveiling the MRH 125 a year ago.

The maximum capacity of the MRH 175 is 10 t, and the maximum jib length is 55 m. The tip capacity is 1.5 t when working with the full 55m jib, or 2.7 t if fitted with 50 m of jib. The maximum line speed is 215 m/min when working with the high-performance 90HPL25 hoist. The crane’s design, with its fixed counter jib and topless structure, facilitates its trademark fast erection and dismantling, as well as making it more compact for transport, needing only four standard containers. The elements weigh under 7.7 t, and there is a single counter-jib/jib foot package. The topless design also reduces the space needed on sites where multiple cranes overfly the job site, and the hydraulic design eliminates wire rope installation. It also means a smaller assist crane is needed for erection as there is no cathead to assemble.

Potain’s hydraulic luffing design features a shorter counter-jib and out-of-service radius than rope-luffing alternatives. This frees up valuable space on job sites, with the MRH 175 delivering an out-of-service radius of 10.2 m, regardless of jib length. Freestanding heights of up to 62.8 m are available with the 2m K-mast sections, and the crane is also compatible with 1.6m K-mast sections. On the hoisting drum, up to 956 m of rope is available with the 90HPL25 winch, allowing users to choose either 478 m in a two-fall configuration with a 5t maximum capacity or 239 m in a four-fall configuration with a 10t maximum capacity. Luffing the crane from the horizontal to vertical takes less than two minutes.

The MRH 175 is one of two Potain cranes that will be on display at the Manitowoc booth during the show, where the company plans to showcase the latest in lifting technology for two of the busiest sectors in the built environment: high-rise construction and homebuilding.
The other crane on show will be the Hup M 28-22 that was introduced in 2019 and is making its North American debut, with a new transport axle for the regional market. The Hup M 28-22 is the third model from the Hup self-erecting crane range and the first to prioritize mobility. The double-steering axle gives the model better job site accessibility and enables it to travel at speeds of up to 80 km/h. The Hup M 28-22 measures 11.6 m when folded, making it the most compact crane in its category, enabling it to easily move from site to site and to be manoeuvred into narrow, restricted spaces at the job site. The crane has a 28m jib and features 16 configurations, which enables it to be adapted for a range of applications.
