Tandem Anchor

• patented

• slotted shell base removes the chance of severely twisted

shells with leaves buckled inward onto the thread

• the system incorporates both mechanical (expansion shell) &

resin anchorage

Other Rebar Product Variations

• coupled bolts

• notched bolts (for bending)

Tandem Anchor

Components

• #6 ( 3 / 4") or #7 ( 7 / 8") headed rebar

• expansion shell (usually D8)• support nut

• washer (2" or 21 / 4")

• for 13 / 8" or 11 / 2" drill holes

• Tandem Anchor Bolts are "POINT ANCHOR BOLTS" because

the full length of the bolt is placed under tension. Resin is

inserted into the drilled hole followed by the bolt. Rotation of

the bolt mixes the resin and causes the expansion shell to

expand and place the bolt in tension. This system incorporatesboth mechanical (expansion shell) and resin anchorage.






Two Piece Tandem Anchor

Components

• #6 ( 3 / 4") or #7 ( 7 / 8") rebar

• 5 / 8" or 3 / 4" headed smooth bar• coupling

• expansion shell (usually D8)

• support nut

• washer (2" or 21 / 4")

• Tandem Anchor Combos are "POINT ANCHORS". The primary

difference in this unit and the Tandem Anchor is the utilization

of two or more individual rods to create a single bolt. This is

necessary when the bolt, to be installed, is longer than the

coal seam is high and the bending of a single bolt is difficult

or impossible.

• In addition to improved mixing properties the

“posimix” device also tends to pump the plastic

skin of the chemical anchor to the back of the

hole which eliminates the ‘gloving’ effect.

• All DSI conventional chemical bolts can be

manufactured as “posimix” bolts and supplied to

suit either left or right hand bolt rotation.

• Recommended hole size is 31 to 38mm diameter.

• Corrosion protection may be provided by hot

dip galvanizing.

Posimix Resin Bolt System

General Features

• Manufacture of the “posimix” bolt is the

addition of a specially designed spring wire

attached to the up hole end of many of DSI

rock bolts.

• The “posimix” bolting system was designed

to assist in the installation of rock bolts with

chemical anchors in larger diameter holes

(31-38mm) by providing:

• substantially enhanced mixing of thechemical anchors,

• load transfer capabilities are maximised,

• the ability to be installed with a face jumbo

as well as hand held machines.

• The “posimix” device centralises the bolt

in the hole allowing an even distribution of

the chemical anchor around the bolt. It also

acts as an Archimedes screw pump forcing

the chemical towards the back of the hole,

assisting in mixing whilst consolidating the

anchor for improved load transfer properties.





Tension Jack/Pull Test Kit

30 Ton Capacity

General Information

• The pull test kit consists of two assemblies:

• a mechanical assembly which includes a claw, stand, nut, & spindle

• a hydraulic assembly which includes a hollow core ram, hand pump, gauge, & hose

• The gauge measures pressure, which is easily converted into tons of load

• Suitable for testing virtually all types of rock bolts and soil nails

• When testing Split Set™, Swellex™, or forged head bolts, the pull collar must be put onto the bolt

BEFORE installation of the bolt

• 30 ton units available for sale or rent

• Comes complete with wooden crate

• Pull test collars available upon request
