KESLA-chippers are shown more dashing than ever on the FinnMETKO exhibition in Jämsä 1.-3.9.2016. For display there are several chippers with multiple renewals. The most remarkable renewal is the new type of rotor, named KESLA logCUT. The new rotor improves the chip quality and even productivity.
The new logCUT rotors of KESLA are available for all three chipper size classes; C645-, C860 and C1060. Knives in the new rotor are straight-bladed. In the previous rotor model the knives were in spiral form or in the row. In this new rotor the knives are positioned whether in four segments (C860, C1060) or in spiral form, but in new way (C645). Amount of knives varies according to the rotor size between 6 and 10 knives. Knife-holders are fastened with bolts but the knives are actually friction-locked. This enables quick change of a knife and minimizes amount of knive-breakages e.g. when hitting stone. The open chip passages of the rotor transfer chips efficiently to blower. The passage construction is patented as well as the lower knife holder. Serviceability of the rotors is in top class due to big amount of changeable parts and for example small rotor’s knives can be sharpened several times and turned around.
- Chip quality with the new rotor is excellent, tells chipper contractor Tomas Backman who has been test using the new rotor since July in his single-axle tractor-powered KESLA C645S chipper.
Another test-user with truck version of KESLA C860, Kurt Häggman, agrees.
- Chip quality has been steadily excellent, he admits. - I have also noticed remarkable increase in productivity with the new rotor in my C860 chipper – from 180 cubic meters to 250 cubis meters. It can also be seen in the fuel comsumption per cubic meter.
Kesla brings to market its own electric control system for chippers
Kesla shows on the exhibition a new proCHIPPER chipper control system, developed by the company itself. It is based on the KESLA proC control system that company developed for cranes and loaders. Both the crane and chipper can be control by the proCHIPPER and it is available for both tractor-powered and truck-powered chippers. The system is used with a joystick or if necessary, through touchscreen, that is part of the control system. In the system there are three different chipping modes ready. The chipping modes can be adjusted and saved individually for four operators.
New chute and chute slewing for smaller chippers
KESLA C645-product family has now got a new chute option, proCHUTE, which widens the working area relevantly. Also the transport position of the chute is lower and its serviceability is good. Slewing of the chute has also got some updates. Benefits are better slewing torque and accuracy. The blower of the C645-model is now equipped with separate wearpart kit. The kit prolongs the lifetime of the blower itself.
KESLA-chipper range in full action
The KESLA-chippers C645S, C860 Hybrid, C860A and C1060A are in full action on the stand 952 on every exhibition day 10/11/13/15 hrs. On the Kesla main stand (numbers 60, 62 and 66) there is also the chipper KESLA C645T-II tandem axle tractor chipper and the new rotor models for display.
