Diesel powered mine drilling rig, The KG726III, KG726HIII down the hole drill rig for
open use is an improved device in
compliance with national regulations on environmental protection.
Equipped with
the Yuchai engine(China Ⅲ), the drill
rig meets national standards for emissions and environment. The tramming motor of
plunger piston and four wheels drive
improve the working pressure and climbing capacity. The expanded pitch and lifting arm
hydraulic cylinder enable it to
meet the requirements of limiting position use. Meanwhile, the hydraulic system is
improved, thereby proving increased
system flow and rotary speed.
The hydraulic cylinder has been optimized, thus making it more reliable. The guide rail
is installed in an inclined way,
making operations and observations easier. The thickened profile is used for the
housing;
and the additional ring makes handling and lifting convenient.
The KG726HIII down the hole drill rig for open use is equipped with a dust collector,
thus making operation more
environment-friendly and reliable.
1, New type feeding system. Using oil cylinder chain pulley makes it having compact
structure, powerful braking and
operation stability;
2, Using famous single cylinder diesel engines as power, it has simple construction and
easy to handle.
3, Reliable hydraulic pump set. Having private hydraulic component increases its
reliability of system. Its oil cooling
system elimates the effection of hydraulic oil heating on system;
4, Professional maintenance team offers good after-sale service;
5, Used abroad and strong gradability.
