The 18RH-II is the second smallest roller head in the Kesla range.
It has the hydraulics and power of large heads packed into a small and light, thinning-friendly package. The second generation of the 18RH series was launched in 2014 and it has now been further improved. Originally the head was equipped with two delimbing knives as standard, and one rear knife being available as an option. Today the 18RH-II head comes standard with three knives. The new frame structure with the rear delimbing knife as standard is more durable and being able to process larger trees.
The 18RH-II’s maximum sawing diameter is 50 cm (19.7 in) and delimbing diameter is 33 cm (13 in), which makes it an ideal head for thinning and for short rotation plantations. The head can be installed on 10 ton wheeled harvesters or excavators. For excavator use, Kesla offers Xtender boom options, which ease up the use of the head with an excavator. The 18RH-II has been designed for a good power-to-weight ratio.
The harvester head range was upgraded two years ago, with the 27RH-II, 28RH-II and 30RH-II models being changed. Last autumn Kesla launched the 29RH-II head, which is a sister model to the 30RH-II. Unlike the 30RH-II with 4 delimbing knives and optional 2WD or 3WD feed, the new 29RH-II has 3 delimbing knives and 2WD feed. The compact design, large diameter feed rollers and a robust construction make the head an ideal tool for felling and processing crooked and branched hardwoods. The head is also available with an integrated top saw.
The 29RH-II is an ideal head for 20-30 ton tracked harvesters or excavators as well as for the heaviest rubber wheelers. It has a maximum sawing diameter of 78 cm (30.7 in) and delimbing diameter of 48 cm (18.9 in). Source
