SElECtiOn anD appliCatiOn i Cosdeos Appropriate components must be suited to the machine size (gross vehicle vehicle weight) and intended application (underoot conditions, machine speeds, travel distances and maneuverability requirements). Additionally, components that provide balanced wear rates and lower operating/maintenance costs will help to enhance the liecycle value o the equipment. Seecg tc Shoes • Single Grouser Shoes provide good penetration and traction. • Double Grouser Grouser Shoes oer less turning resistance or greater maneuverability. • Triple Grouser Shoes Shoes oer the lowest penetration and resistance and best maneuverability. maneuverability. • Special Use Shoes, Shoes, such as fat, fat, sel-cleaning, and rubber/polyethylene-bonded, are available in some sizes. • Extreme Service Shoes provide longer wear in high-impact and abrasive conditions.
Me those tcs ls To help your customers gain the best perormance rom your machines, encourage them to: • Minimize high high operating speeds in nonproductive situations. • Adjust the track or correct tension in the working environment. • Make daily visual visual inspections o the equipment. • Keep the undercarriage undercarriage clean o mud and debris. debris.
