URBAN SMV70 with conveyor 2,1 m

« »

The Branch Logger URBAN SMV70 is powered by a 10 hp (optionally 14 hp) Briggs & Stratton VANGUARD engine. The power is transmitted from the engine by the V-belts on an oil-filled gearbox which drives the logger. The SMV70 features an offroad chassis with independent pivoting axles.

UP TO DIAMETER 80 MM

Part of the machine is: tow hitch with tow ball ISO50, operators manual including declaration of conformity.

The engine

The SM70 is driven by a four stroke 10 hp Briggs & Straton VANGUARD engine, with pull cord or optional electric starter. The engine´s output is transferred via V-belts to the oil filled gearbox which drives the blade rotors. The fuel tank capacity is 4 litres. Upon request, a logger can be equipped by hour meter.

The chassis

The logger has off road chassis that is able to overcome larger terrain inequalities thanks independent pivoting axles. There is a one pull-out wheel in front of the trailer and adjustable leg at the back side of trailer. The centre of gravity of the machine is slightly before the axle. Connects to a vehicle with a 50 mm dia. tow ball. It is possible to attach a small trailer to a classical hinge or to 50 mm diameter tow ball. The SMV70 is not intended for a highway use.

The belt conveyor

It is used a 2,1 m long belt conveyor driven by V-belt. The conveyor slope is adjustable by a winch. The conveyor is lifted to the vertical position during transport. It is possible to install on the end of conveyor following accessories: the 0,8 m slide or a double bagging device with a support leg. The bagger is attached by four screws and assembly takes only a few minutes.

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 Overload protection

If you put too large branch in the chipping-device, V-belts slip shortly and the engine stops. This is the way how to protect the branch logger against overload. When this situation happens, it´s usually impossible to take the branch outside of the chipping-device, because knives are jammed in the branch. In this situation, make sure the engine can not start itself, put away the small round cover of V-belts and turn over with the sheave clockwise until the branch is out of the chipping device. Then, please put the cover back on the place.

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 70 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 100 to 500 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.

The tow hitch

The Branch loggers attached behind the tractor can tow a trailer with a regular tow hitch or a tow ball ISO 50. The maximal weight of trailer is 2000 kg.
