CRAWLER SHOES / TRACK PADS


Bradken has extensive experience in delivering top quality crawler shoes for electric rope shovel and hydraulic excavators to the mining industry. Our products offer superior component life over alternative suppliers whilst also achieving competitive pricing. This enables Bradken to be the preferred choice when it comes to undercarriage components.

HYDRAULIC EXCAVATORS




The Evolution range of quenched and tempered crawler shoes was developed by Bradken to overcome the shortfalls in traditional designs for the Caterpillar® hydraulic excavator platforms. 
Evolution crawler shoes have thickened pin lugs and feature Bradken's patented 'continuous roller path'. This roller path design enhancement improves the contact pressure distribution between the roller and the shoe. As a result, the roller is supported at all times.


Features Benefits
Continuous roller path, improving contact pressure distribution
between the roller and shoe.

Reduced metal flow on shoe roller path, increasing the service life of mating components.
Simplified nut/bolt pin retention system allowing for ease of installation, removal and maintenance. Safer and faster installation, resulting in less downtime.

Manufactured from induction hardened NiCrMo cast steel. Able to handle high impact loads with increased wear resistance.



The Opti-Trak range of crawler shoes developed by Bradken for Caterpillar®, Hitachi® and Komatsu® platforms, offers significant advantages over traditional shoe designs. Most traditional shoes are case hardened, bu the base metal is softer underneath meaning wear rates increase over time.

Bradken's Opti-Trak shoes are through hardened to give excellent wear resistance and uniform wear rates all the way through the metal section.
The roller path is supported by Bradken's patented 'Pillar of Strength' to prevent crushing of the worn shoe later in its service life. Other areas of high wear and those subjected to significant impact strikes have been strengthened to provide greater structural integrity.

Opti-Trak crawler shoes are interchangeable with the existing OEM components.

Features  Benefits
 Through hardened to provide excellent wear resistance and uniform wear rates all the way through the metal section. Increase service life.
Roller path supported by Bradken's patented 'Pillar of Strength' to provide
greater structural integrity.
Increased operational performance and shoe life.
Connecting pins manufactured from induction hardened 4340 grade steel.  Reduced pin failures and unexpected machine downtime.
 OEM interchangeability.  Easily integrated as replacement parts into OEM tracks.

ELECTRIC ROPE SHOVELS



Bradken developed the Ovation range of crawler shoes and undercarriage components to provide improved performance for Caterpillar® rope shovel users. 

The Ovation shoe range has alternative materials and optional shoe lengths for the various mining conditions. 
Ovation 79” and 84" length crawler shoes for heavy duty, hard rock conditions are manufactured from BKC400 material providing excellent wear resistance and uniform wear rates. Bradken’s patented “Pillar of Strength” provides roller path reinforcement and improves the crawler shoe’s ability to transfer machine loads to the ground. 

Ovation 125” and 140” length crawler shoes for high flotation applications are designed specifically for mining operations where low ground bearing pressure is required. The shoes are manufactured from BKCS30 material providing excellent impact resistance combined with the superior wear rate properties of the induction hardened surfaces. Safety and ease of pin removal on site has been enhanced with the addition of pockets specifically designed to facilitate the use of hydraulic cylinders to push the pins out of the bores.
