URBAN SM110 with turntable and folding belt conveyor 4,1 m

The engine

The SM110 is driven by a 35 hp Briggs & Stratton VANGUARD engine with electric start, an oil level and fuel indicators and an hour meter. The fuel tank capacity is 15 litres. The engine´s output is transferred via V-belts to the oil filled gearbox which drives the blade rotors.

The frame

The SM100 frame with turntable is equipped with four foldable legs. The lower part of the frame is adapted for handling with a forklift - two large rectangular hollow profiles holes with internal dimensions of 190 × 90 mm (see technical drawing).

Thanks to its foldable legs, the SM110 can be used either as a stationary unit – by folding down the legs and placing the machine on the ground – or mounted on a trailer.

The frame is fitted with four screw holes for fixing the machine, or it can be fixed by straps. The overall dimensions of the floor plan are given in the technical drawing. Two suspension lugs at the top of the machine can also be used for handling.

The turntable

The branch logger is fixed to a 360° turntable to allow the branch logger to be rotated in eight lockable positions in 45° increments.

The inlet hopper

The hopper is long enough to provide safety and is equipped with a safety shut-off frame, which by pressing down stops the engine. The inlet hopper is oriented horizontally, which greatly facilitates insertion of long branches compared to the vertical or sloping hopper. Surface treatment of the whole machine is made with powder paint.

The folding belt conveyor

The conveyor is driven by V-belt drive. The slope of the conveyor is adjustable by means of a winch. The conveyor is folded and lifted to a vertical position during transport.  As an optional accessory, it is possible to mount a double bagging device with a support leg at the end of the conveyor. The bagging device is secured by four screws and it takes only a few minutes to fit it.

The overloading protection

A belt slip protects the device from overloading. If a too strong branch is inserted, the belt will be slipped and the engine stopped. If they do, the knife blades will usually be bite in the branch and can not be freely removed from the hopper. The supplied lever is used to release it. Release the branch by clockwise lever rotating. 

The chipping device

The working principle of branch loggers URBAN lies in two counter rotating shafts with knives. The rotating knives draw in the wood material into the feed hopper unassisted. The passage gap between the shafts is 110 mm. Each shaft has 3 fixed knives, made from high quality tool steel. It is possible to resharpen the knives repeatedly. After sharpening there is a pad to be put under the knives in order to keep the same gap between the knives (c. 0,1 mm). One single sharpening of knives is capable of producing from 150 to 800 solid meters of small logs, depending the level of contaminants (mud, nails, stones etc.). Each blade can be sharpened up about 4 mm, then it must be replaced with a new one.
