Tilting saw
A tilting saw (also firewood tilting saw, tilting circular saw , tilting circular saw ) is a special circular saw for cutting firewood .
The saw blade , which is arranged at right angles to the V- or U-shaped rocker, rotates in a protective device. In the right part there is a slot into which the saw blade dips. The rocker is located in the lower area of the frame and must be guided against the saw blade with light pressure. The blade protection device opens and closes in parallel with the rocking movement. The pieces of wood or logs are placed on the rocker on the left, sawn off accordingly and fall down on the right.
safety
In order to prevent the rocker from sticking to the saw blade by itself, a spring pulls the rocker back to its original position after the operator has released it. Newer saws usually have an electronic brake switch with zero voltage release .
The saw blade cover was missing on older tilting saws. The saw blade was freely accessible. Such tilting saws should no longer be used or should be retrofitted with a protective device due to the high risk of accidentally getting into the freely running saw blade.
A further development of the tilting saw is the revolver saw or drum saw , in which the pieces of wood are inserted into a rotating drum with several compartments and a vertical or inclined shaft, slide down to a stop plate and then (as with a sausage cutting machine with a side stop ) automatically to a preset length are cut and are guided again and again by the drum to the cutting blade.
drive
Most often, an electric motor is used as the drive source. With inexpensive do-it-yourself tilting saws with a circular saw blade diameter of max. 500 mm, a 230 V motor is used, for semi-professional and professional use only 400 V three-phase motors are used, which either drive the circular saw shaft directly or drive the circular saw shaft via a V-belt . There are models with PTO drive for use directly in the forest . Combination devices with an electric motor and PTO drive as well as gasoline-powered tilting circular saws are also available.
