TR110 Branch Logger
   
 
 
 
 

The TR110 Branch logger is mounted on the rear three-point hitch on the tractor. The drive is provided via a PTO shaft with an overload clutch set to a torque of 1600 Nm, which stops chipping if too strong a branch is inserted. The overload clutch protects the tractor and branch logger against overload.

The cutting knives feed the branch itself when the machine is running. Logs then fall into a bag mounted on a double bags-filling device. After filling the first bag there is no need to interrupt work due to a full bag, because you can just flip the flap and the logs fall into the second empty bag.

During the filling of the second bag, the operator can replace the full bag with an empty one. During the continuous input branches can be filled in one bag in 10 seconds, so performance is highly dependent on the operator, especially on the speed of operation when the bags are being changed.

The branch logger is equipped with a hinge for connecting a trailer with a maximum weight of 2000kg, which could be filled with full bags.
 
 
 

The maximum-diameter branches or small trees can only be inserted one at a time. If the branches are thinner, you can also put more of them in at a time. The minimum recommended tractor power is 50hp. Optimum performance is 70hp of tractor power. A tractor with this power can work at lower speed (about 1300 RPM min).

The size of the tractor must be proportionate to the weight of the branch logger, which is 650 kg. Alternatively, the tractor must be balanced at the front. PTO is included and works at a 1000 rpm speed (it can also work at 540/rpm, but at low speeds the feeding of branch does not work as well). Drive of branch logger is through the gearbox with oil filling. The surface is painted with a powder coating.

The hopper of the branch logger consists of fixed and hinged parts. The tipping hopper ensures the narrow width of the machine in the transport position. The width of machine does not exceed the width of tractor, which is important for a ride in the forest through the trees. The hopper is extended in the working position thanks to tilting of the tilting hopper.  The extended hopper ensures a better flow of branches and operator safety. The hopper is oriented horizontally, which greatly facilitates the insertion of long branches, compared with a vertical or oblique hopper.

The branch logger is raised by the tractor hydraulics The optimum working height is when the lower edge of bags-filling device is 80 cm from the ground. The chains are used to ensure machine stays in this position. These chains are supplied with the branch logger. The alternative solution is putting the branch logger on two special stances which are also delivered with the branch logger.

The chipper device operates on the principle of two shafts with knives which are rotating in opposite directions. Pitch diameter of knives is 224 mm and the through gap between the shafts is 120 mm. The chipper knives are inserted into grooves in the shafts. Each knife is attached by four screws.
The knives are made from tool steel and can be re-sharpened. The knife is supported by a pad after each sharpening.  There must be a small gap (maximum 0.3 mm) between knives. The knife can be ground down to about 4 mm. Knives  can produce more than 1000  bags on one sharpening. It depends on quantity of impurities (clay, stones, etc).  Welmac UK are the sole importers for the UK and Ireland.
 
 
 

 

The trailer can connect to the classic hinge or to the ball hinge with diameter 50mm.
