Potain is to launch the 10 tonne MRH 175 luffing jib tower crane at Conexpo next month and follows the launch of the eight tonne MRH 125 a year ago.
Maximum jib length is 55 metres, built up in five metre increments with a jib tip capacity of 1.5 tonnes or 2.7 tonnes with 50 metre jib. Fully luffing the jib from horixontal to almost 90 degrees takes less than two minutes and the maximum line speed is 215 m/min with the high performance 90HPL25 hoist.
Potain says the fixed counter jib and topless structure design helps speed erection and dismantling as well as making it more compact for transport requiring only four standard containers. No single crane component weighs more than 7.7 tonnes.
The MRH 175 has an out of service radius of 10.2 metres. Freestanding heights of up to 62.8 metres are available with the two metre K type tower sections and the crane is also compatible 1.6 metre K tower sections. Almost 1,000 metres of rope storage is available with the 90HPL25 winch.
Thibaut Le Besnerais, vice president of global products for tower cranes, said: “Hydraulic luffing topless cranes have a very strong future in our industry, and we have been pleased with the uptake over the past two years. Potain customers have seen the advantages these new cranes deliver and how they help them achieve a stronger return on investment on their projects. We have a strong technical training program to accompany our new MRH cranes, and the feedback from the market has been very positive.”
Manitowoc will also unveil the Potain Hup M 28-22 - complete with a new transport axle for the regional market at Conexpo.
