February 5, 2007—R+W America developed the EZV series of adjustable length line shafting, which uses the same jack system for various platform sizes in lifting applications.

Manufactured from high strength precision aluminum tubes that exhibit a high degree of straightness and lateral rigidity, these shafting systems can span lengths of up to 15 feet without an intermediate support bearing.

On each end is a set of precision machined curved jaws with a pretensioned elastomer insert loaded between them. The coupling ends are removable so that only one additional component is required in order to adapt to an alternate bore diameter.

One of two lengths of the tubing telescopes into the other, which uses a high strength keyless clamping collar to lock them together. An additional close fitting shoulder on the end of the smaller tube helps to support its own weight against the inside wall of the larger tube. As the tubing is cut to length in order to meet customer requirements, the available range of length varies, growing larger as the overall length dimension increases. In addition, length requirements can be input on the R+W website for immediate calculation of possible ranges.

These line shafting systems offer four different choices for the shore hardness of the elastomer insert and are made in sizes to accommodate a torque range from 10-2150 Nm (88.5-19,027 in.-lbs.)Bores are available with or without keyways and in English and metric sizes for a range of 5-80mm (0.25-3.125").
