◆ The “V-groove” design allows the bars to be bent around a side-bucket prole or separated to meet
different length requirements.
◆ No pre-heating or post-heating required when welding bars in place.
◆ Available with or without notched backing plate.
◆ No pre-heating or post-heating required when welding wear bars in place.
◆ Strategic placement of GK wear bars causes “rock box” protection or “dirt on dirt” protection.
◆ Provide protection on heavy earth moving machinery.
◆ Perfect for rock-box protection, impact areas and transfer points.
GK Chocky Bars
◆ Ideal for smaller areas requiring wear resistant material.
◆ The round shape of GK Wear Donuts virtually eliminates any chance of a weld cracking and provides
maximum protection while minimizing the effects of impact.
◆ GK Wear Donuts are perfect alternatives to expensive and labor intensive hard facing or the need to cut
wear strips from full sheet of wear plates.
◆ GK Wear Donuts also offers exible attachment options with the feasibility of internal and external
welding.

◆ GK Boomerangs are routinely used for making up protection packages on buckets, rock boxes, truck
bodies and screen decks.
◆ They are easy to install and can provide an easier option to cutting various plates to protect wearing
areas.
Roll Bars
◆ The curved radius provides maximum wear protection while diverting the ow of material.
◆ Their high, narrow prole makes them usable in tight spaces on screens and they are often installed in
impact areas to create deep material traps boxes.

◆ Ideal for smaller areas requiring wear resistant material.
◆ The round shape of GK Wear Buttons virtually eliminates any chance of a weld cracking and provides
maximum protection while minimizing the effects of impact.
◆ GK Wear Buttons are perfect alternatives to expensive and labor intensive hard facing or the need to cut
wear strips from full sheet of wear plates.
GK Wear Plates
◆ GK Wear Plates have a thicker prole, which allows for extended wear life in extreme applications.
◆ Ideal for chutes, hoppers, bins, liners, impact walls, rock boxes and a lot of other applications, GK Wear
Plates help to reduce down time and increase output.

Heel Shrouds
◆ Shrouds are cast of low alloy steel for excellent wear resistance
◆ Protection is given to the bottom and the side of the bucket with extra wear material concentrated in the
corner where it’s needed most.
◆ The inside corner is relieved to eliminate interference with the bucket structure.
◆ They can be spaced apart and still provide full protection due to ‘shadowing.’

Forming Instruction
For severe curves with radius less than 305mm, or inside
curves, it is advisable to notch the steel backing plate opposite
the "V" to assist forming (FIG D). Please note the chocky bar
may crack during bending. This is normal.
- Clean the surface to which chocky bar will be welded onto.
- Tack weld one end of the bar by 15mm min. length per weld
(FIG E).
- For outside curves: Hammer down the unwelded and with a
soft face hammer to bend the bar to match mating radius
(FIG F).
- For inside curves: Starting in the center, strike the bar with a
soft face hammer to bend the piece to match mating radius
(FIG G).
- Stitch weld as per the welding procedure.
Cutting Instruction
High pressure water jet cutting is recommended. Thermal
cutting using oxyacetylene torch, arc-air or plasma is not
recommended. Abrasive disc cutting is accepted for blocks
less than 25mm section thickness:
- Secure the block in a vice or clamp.
- Notch the backing plate (FIG A) and notch the white iron a
3mm deep opposite the notch in the backing plate (FIG B).
- Wrap the block with a rag and carefully hit using a soft face
hammer. The block should break cleanly at the notch.
Welding Instruction Ensure the surface which the block will be attached onto is as
at as possible and the area to be welded is clean.
- Clamp and tack weld the block into position.
- Stitch weld, laying 50mm max. length each run, alternating
ends or sides to minimize heat penetration. DO NOT deposit
weld within 2mm form the joint(FIG C).
- DO NOT WELD CONTINUOUSLY - Continuous welding may
cause warpage,delamination and cracking. Maximum
temperature allowed is 200℃.
- Using low hydrogen weld rods or gas covered cored wire.
