Air legs of P1, P2 and P3 are intended for giving of pneumatic figurative perforators of the software and FRIDAY types on a face and their maintenance at a certain height.Three standard sizes allow to choose the necessary support in strict accordance with conditions of performance of work.
Fastening of pneumatic support to the perforator provides fast and reliable accession and a detachment without application of a special purpose tool. Simple and rugged construction of a product guarantees smooth operation and cuts operational costs to a minimum.
Pneumatic supports represent the steel cylinder, in which are placed the piston with the rod which is put forward under the influence of squeezed (to 0,5 MPas), of air. On the lower end of a rod the fixing pointed emphasis providing stability of an air leg during the operation of the jackhammer is located. On the upper end of the cylinder of an air leg there is a device for fixing of the jackhammer and its installation at any angle of an inclination irrespective of the provision of an air leg.
Kind of an air leg - the telescopic device in the telescope jackhammer. For decrease in vibration and increase of a drilling rate the telescopic device rigidly connects to the jackhammer body so that the axis of a rod matched a longitudinal axle of the drill stem.
