Soild and reliable
Wide range of use
Left Rotation Anchor Rod no longitudinal ribs resin bolt steel bolt, high strength,
reasonable structure, preload force, able to automatically adjust the direction of the force, increasing the
binding on the
rock, to achieve mechanization quick installation.
Left-handed anchor rods have been widely used in many industries, especially in:
coal mines, tunnel construction, bridge engineering, railway construction,road engineering, high altitude areas and so on.
All have been widely used.Played a decisive role in engineering construction.
Coal mine use
Do you know the funcatioanl characteristics
of left-handed anchors?
Technical characteristics of left-hand bolt
Anchor rod high strength, reasonable structure, preload force, ableto automatically adjust the direction of
increasing the binding on the rock, to achieve mechanization fastinstallation. Could end anchor。
the anchor and the whole extended anchor, mainly for high
pressure large Deformation mine roadway support high-strength,but also can be used for railway, hydropower and
other projects ofhigh strength, permanent roadway.
ADVANTAGES OF LEFT-HAND BOLT
(1) The structure is reasonable, and the full length of the anchor bolts is equal in strength, which solves
the shortcomnings of lowstrength of the anti-twist anchor bolt thread and flattening.
(2)40% higher load capacity than anti-twist anchors of the same specification
(3)The operation is simple and the price is low.lt is widely used in various roadway support in coal mine,
railway , hydropower andother projects.
BASIC CHARACTERISTICS OF LEFT-HANDED ANCHOR
China doal Machinery Manufacturing
The left-handed bolt structure is reasonable, and the full length of the bolt is equal. it solves the
shortcomings of ant-torsion anchorbolt threads and low strength of flat parts.
Lef-handed bolis, simple operation and low price, are widely used for roadway support in coal mines,
railways, hydropower and otherprojects.
Alloy drll it lt is made of high-quality ally by precision technology , with strong hardness and toughness,
and the penetration forcecan make the bolt drill into many types of surrounding rock.
Anchor body: The most important component in the assembly, which plays a major role in drilling and anchoing
Connecting sleeve: connect when the anchor rod needs to be lengthened.
Backing board: can withstand greater stress of surrounding rock.
Nut: can concentrate the surrounding rock stress on the backing plate.
