Tower Crane

Used in the construction industry, tower cranes fixed to the ground or on rails provide the best combination of height and lifting capacity. A full range of gearboxes developed by us for tower cranes are used for traveling applications, slewing, hoisting and luffing. Dedicated shaft-mounted solutions are available for rail-mounted cranes. Planetary gearboxes for slewing are usually supplied with an integral pinion designed for lifetime service. A helical gear unit complete with a 2-speed shift gear, one speed for working phase with load and the other one for fast climbing and descent without load, is a specific solution for high tower cranes, where operation speed is a must. Our shaft-mounted POSIPLAN is a highly appreciated ultra-compact solution, as well as being lightweight compared to similar equipment, and can be positioned strategically on the tower crane. All POSIPLAN input supports are designed using dedicated bearings for input high speed (up to 3500 rpm intermittent) as opposed to tapered roller bearings.
