These include the Kesla proC electric control system for top-seat and the Kesla 2124ZT Z-boomed crane.
Electric controls are now available for top-seat equipped cranes. Electric control systems have become more and more popular in cranes due to their smooth and easy use. In Nordic countries, mounting of electric controls is not a big problem as a well-insulated, comfortable cabin is preferred due to weather circumstances. In many countries where the top-seat is a preferred option, the electric system is more vulnerable for weather-related problems (especially moisture).
The system Kesla presents is built on Parker’s L90LS valve. The valve is controlled with the Kesla proC control system. The system and the joysticks are fully weatherproofed. The system allows the user to make several adjustments and even to save the settings for up to six persons. Controlling of a crane is easy and smooth.
The Kesla proC system also has a feature called “Motion Balance”. It enables moving the crane in case of too low hydraulic flow. The first official crane deliveries with the Kesla proC top-seat will take place in the beginning of 2019. The system will be available for most models in the Kesla 21 series. By 2019, the new weather shelter for the top-seat should be available.
Kesla also presented the 2124ZT crane at Interforst. It is a big, Z-boomed crane with double extension, an outreach of 9,7 m (31.8 ft) and lifting torque of 219 kNm. This strong crane is suitable for timber loading. Z-cranes have increased in popularity due to their practical transport position. The crane is also available with single extension (outreach 8,2 m / 26.9 ft). It can be equipped with the Kesla Vision and Vision XL cabin or with top-seat. Source
