Engineering Directional Boring Machine With Auto Anchoring / Auto
Loadin
1, GENERAL
DL200A horizontal directional drilling machine refers to an engineering machine
designed for the purpose of pipeline laying in case of no
eacavation of earth surface,and is widely applied for laying
pipelines for urban water supply,gas,natural gas,power and
petroleum etc.It is automatic,full-functional and fitted with shaft
set assembly,automatic anchorage baseboard,laege-tonnage hoist
etc.characterized by high rotation speed,high torque and pull-push
force,and high travelling speed,and compact structure ect.
1.1 Applicable Scope
It is applicable for crossing construction in non-hard rock areas
nationwide like soil,clay,sandy soil and weathered rock areas.its
ambient temparature is -10℃±45℃.pull-back pipe diameter
150mm-700-mm and maximum crosiing length about 300m(as the case may
be)
1.2 FEATURES
1.2.1 with the adopting of Cummins Series B 110KW engine especially
for engineering machine ,the machine has reliable power and can
provide 200KN pull-back force.200KN upsetting force,5900N.m torque
and maximum power among the drilling machines of same tonnage.
1.2.2 With the adoption of imported main hydraulic parts ,like
PERMCO EATON and PALL.the machine has reliable performance and
guaranteed quality.
1.2.3 Automatic replacement of drill pipe
The machine has automatic raplacement of drill pipe system,change
drill pipe very simply and quicky.
1.2.4Automatic anchorage devices
The machine is fitted with an automatic anchorage baseboard which
can operate the selector valve for automatic anchorage to ensure
raliable fixing of the machine and reduce labor strength.
1.2.5Rubber crawler
The machine is fitted with rubber crawler to protect the pavement
and minimize damage when it travels in urban area.protection area
and scenic spots.
1.2.6High-performance filter
Famous international PALL filter score is employed for this
machine,which has powerful waste removal and rosolution capacity
and can guarantee reliable operation of the drilling machine for a
long time.
