Company ProleGK INTL, headquartered in the CBD of Changsha, Hunan, with an ofce area of 13,000 square feet , is

a leading supplier of excellent wear solutions to ght against impact & abrasion challenges with a

48,000 square feet of manufacturing facility in the suburb. Established in 1984, we strive to deliver

superior customer service, on-time delivery and competitively-priced solutions for our customers all

over the world.

GK Wear SolutionsGK Wear Solutions is a combination of products, services, and metallurgical expertise to provide

superior wear protection for mining equipment and other industrial applications. Featuring chrome

white iron, high manganese and low alloy steel material, GK INTL always seeks to provide innovative

material to prolong wear life and reduce downtime.

ApplicationGK Wear Solutions have a variety of applications in buckets(excavator, loader, dragline, face

shovel),crusher spider arm guards, feed and discharge chutes, rock boxes, feeder grizzly bars,

shredder and grinding mills, sugar cane knife edges, adaptors/attachment protection, dredging

equipment, screen-feed distribution, hopper wear areas or any other equipment exposed to abrasive

wear. In addition, GK Wear Solutions can be custom-designed to your particular application. GK Wear

Solutions are designed to work in the ruggedest impact and abrasion environment to reduce down time,

maintenance cost and increase productivity.

Dimensions(in/mm)

◆ The “V-groove” design allows the bars to be bent around a side-bucket prole 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 Shaped Bars

◆ GK Shaped Bars are non-STD bars available in different shapes to suit your unique applications.

◆ GK Shaped Bars are perfect for prevention of gouging wear and thus allow the buckets or

machines to work far longer.

◆ No pre-heating or post-heating required when welding shaped bars in place.

◆ Easy to cut and shape over contoured surfaces.

◆ 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 prole 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 prole, 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 InstructionFor 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.
