PERMON s.r.o. VKP 95-1 – OPERATION MANUAL PAGE 3
Preface
This operation and maintenance manual provides the drawings, parts lists and
suggested procedures necessary for the operations, care and maintenance of the
VKP 95-1. It is extremely important that all the suggested safety precautions, as well
as user’s safety rules, be followed. PERMON is not responsible for damage to
equipment or personnel injury due to misuse of the equipment or disregard for safety
procedures.
Principles of Operation
The VKP series of downhole hammer drills are designed for efficient operation with
minimum air requirements in a wide range of air pressures. These hammers are
recommended for blasthole drilling in quarries and open pit mines as well as water
well and construction drilling applications. The downhole drilling method has proven
to be economically effective in a wide range of rock types ranging from
unconsolidated limestones to the hardest granite and quartz formations. Since the
hammer force is applied directly to the drill bit, power transmission losses as are
common in conventional top hole hammers are prevented.
These hammers can be used on any rig having an adequate rotational mechanism
and an appropriate compressed air supply.
