YT28 Rock Drill&Pneumatic Rock Drills-YT28&Air Leg Rock
Drill-YT28-Production Description .
◊ It is a new type of efficient drilling equipment. It is widely
used in tunnel heading and blasting holes drilling in mining. It is
also indispensable equipments in metallurgy, coal mining, railway
construction, transportation projects, water conservancy and
national defense building.--
◊ YT28 air-leg rock drill has wide applications. It is applied to
drilling holes horizontally or with inclination on rocks with
middle and high hardness (f=8-18),and drilling boreholes which are
perpendicular to the rock face of roof. The diameter of the
blasting holes is usually 34-42 mm, and the depth of the effective
and economical holes can be 5m. This machine can also work with
different air legs - FT160BDshort leg, FT160BC long leg, or FT160S
double legs, to fit in different sizes of tunnels. Besides, it can
also work when connected to bore jacklegs or drilling lathes.
◊ YT28 uses supporting oiler of FY200B, which has a shell made of
polycreosotester, allowing for observing and controlling the volume
of oil to ensure good lubricating effect
handle and maintain.
◊ Low noise, small vibration, energy-saving and efficient, highly
interchangeable parts with long service life reliable performance.
◊ Different from similar products particularly in its high
efficiency, strong flushing and powerful torque.
Operation & Maintenance:
Besides observance of the general safety precautions for rock
drilling operations, the following points should be attended to:
◊--The Rifle nut and the piston are left-hand threaded. Cautions
should be taken during assembling and Disassembling.
◊-Before connecting the drill to the air and water supplies, check
carefully if the wire clips are entirely and correctly set in the
respective semicircular grooves of the back-head. Check frequently
the wear on the clips and timely replace the worn-out or broken one
to avoid the scooting out of the swivel or the connector when the
air or water is on
◊-Before operation, fill the line oiler with lubrication oil to the
required level. The drill should not work without lubrication
oil(recommended lube oil N46 and N22, Chinese National Standard
◊ After operation, first turn off the water, run the drill lightly
for a few seconds, blow out the residual water, drops to prevent
the parts from being corroded.
