URBAN SMH110 with conveyor 2,6 m

The engine

The SMH 110 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 road trailer

The SMH110 is mounted on a highway use braked single axle trailer with road lighting kit and number plate holder. There is a one pull-out wheel in front of the trailer and adjustable leg at the back side of trailer. The machine is connected to a vehicle with a 50 mm diameter tow ball. The total weight of the trailer with logger is 1300 kg.. The centre of gravity of the machine is slightly before the axle. The driving license of group „B“ is sufficient for combination of vehicles of up to 3 500 kg (the total towing weight is 2 200 kg). 

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 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 lifted to a vertical position during transport.  As an optional accessory, it is possible to mount a slide with length 1m or double bagging device with a support leg at the end of the conveyor or . 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.
