Accesories possibilities for the Africa SL130s and Africa SL160s

We do manufacture the sawmill according to your own requirements. Following you will find the possibilities for the Africa SL130s and Africa SL160s models:

 

 

How much confort?

In our V cockpit all the functions are ergonomically placed surrounding the operator. It is also availble with an air conditioned cabin so the operator has a calm free of sawdust working place. If required adjustable in height, with a leather chair, joystick, computerized positioning. Most of the hydraulic functions can be electrically driven. The electric box is easily reachable from the operators place

Special wheels for transport

In order to change the working place in difficult terrain we offer to our customers a plug in wheel set for the 7 m cutting length. 4 tons capacitie on each wheel. Easy to mount or dismount. To be transported you need a tractor or caterpillar


Pre-cutter

With a circular blade the precutter cleans the bark on the side where the sawblade cuts into the wood. Because of this the life of the sawblade is extended. Because the different trees we have different barks (talking about their thickness) and this is why at our pre-cutter you can easily adjust the deepnes of the cut. It also has a system tha protects the precutter from being damaged due to misuse.

Sawdust collector

Normally the sawdust falls along the machine. Under windy conditions, it makes life to the workers imposible. The sawdust collector, collects the sawdust and can be emptied at any desired place as for example a container. At stationary sawmills this is solved by using a vacuum system

Computerized positioning

Exact positioning of the sawblade. A digital computerized positioning system (SPS) grants you a fast and easy positioning of the sawblade with tolerances of +/- 0,2mm. Simple and easy to be used, different cutting programs.

Water spray

For strongly resinous wood, it may happen that for the blade you need water, so the sawdust does not glues on the blade. Previously, every sawmiller added manualy water to the sawblade by themselves. We solve the problem with a  installed tank system at the sawhead. When needed just open the tap. A second method is the water from the container via a pump through a nozzle to spray the band saw blade evenly and sparingly with water.

Log lifters

They lift the log and place it on top of the sawbed. It consist of several arms. Its power is up to 4,8 t



Squaring arms (Standard)

They avoid the log from falling done while being loaded and they help you for getting an cutten wood at an exact 90° angle. They are adjustable. The small wheel on the top helps you to turn bigger logs. Combining the squaring arms with the computerized positioning avoids to cut them off. Should the sawblade be under the height of the squaring arms, the sawhead will not move forward.


Roller drum

Moves the log on top of the sawmill backwards and forwards so you can position it in the best possible way in order to be clamped by as much as possible toe boards with clamps. One cilinder raises the roller drum and an hidraulic engine, moves the log in both directions. By using more of this roller drum you can move the cutten products up to the end of the sawmill.


Log clamp turner

They turn the log into the desired position. They do not damage the wood and they are fast. You can also turn a whole bunch of boards with it and because of this they make your life easyer by doing the double cut and at the same time increasing the output of your mill. They also fasten and clamp the log at the exact 90° angle. They also help to displace the cutten boards into our lateral board removing system. Recommended are two log clamp turners. It makes sense to have also the smaller turner of the Bavaria serie, so you can turn smaller logs easier. Chain turner are also available on request.

Clamping system

The toe boards with clamps level the log so that the center of the log is parallel to the sawing table. They also clamp the log (Adjustable height clamps) and pull it against the sawing table. This is very important feature for long timber that can twist while being cut. Approximately 50% of the logs that are being cut, have such a lot of internal tension that they twist. At the Africa we do not only use stainless steel on the sawing table to avoid any staings while cutting Oak and Larch, we also use stainless steel on the top of the toe boards with clamps just to be sure.

Unloading arms

By turning the logs, the bark and boards fall above the squaring arms. The unloading arms are lifted creating an angle and the main products roll down the receiving arms.


Lateral arms beside the mill (Receiving arms)

The boards are received from the unloading arms. As receiving arms we have three options. Option 1: The wood rolls on this arm and falls on the floor, from where is has to be picked up. From there the boards can be placed on a conveyor. Option 2: The cut wood is received by the lateral atrms beside the mill, by lifting them up the boards will be stopped by a holder. From there it can be removed by hand or by fork lift. Option 3: The cut wood is received by the lateral arms beside the mill and once they are lifted the boards fall directly on to a conveyor.
