Kesla launches a new generation of Z-cranes as the 22-series. The new Z-cranes are available in the 12-, 14- and 17-tonne-metre classes. Their design is based on strength, speed, stability, outreach and easy maintenance. New operating valve for the electrically controlled cranes The design of the new cranes set out to increase speed and usability. To achieve this, Kesla has, for example, chosen to use an electric valve with a higher throughput volume than the previously used. The lines to the transfer and extension cylinders have been enlarged, enabling higher crane motion speeds and improved manoeuvrability. - “We have designed the most efficient and durable Z-crane on the market,” says Ari Pirhonen, Business Director. The valve is controlled by Kesla’s electric proC control system available in a variety of control options ranging from mini joysticks to a 4-lever and 2-pedal option. New valves are also available for mechanical control The transfer boom of the new Z-cranes is almost completely redesigned. The need for change was partly due to practical reasons: larger lines require more space. The new structure includes, for example, a modified extension cylinder design, different size casings and larger pins. Despite an increase of up to 30 cm in the useful outreach, the changes have been implemented with hardly any increase in weight.
