INTERODUCTION OF

LEFT ROTATION ANCHOR ROD

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.

APPLICATION SCOPE OF LEFT-HANDED ANCHOR

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.

Technical characteristics of left-hand bolt

Anchor rod high strength, reasonable structure, preload force, ableto automatically adjust the direction of the force, 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.

ONE

ADVANTAGES OF LEFT-HAND BOLT

China Coal Machinery Manufacturing

PRODUCT ADVANTAGES

(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.

TWO

BASIC CHARACTERISTICS OF LEFT-HANDED ANCHOR

China doal Machinery Manufacturing

REASONABLE STRUCTURE

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.

THREE

ADVANTAGES OF LEFT-HAND BOLT

China Coal Machinery Manufacturing

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.
