Strengthened undercarriage for higher durability even in heavy-duty applications.

Higher durability with special reinforcement and stressrelieved welding.

The boom-end rigidity through the use of a thick single plate and increased boomend bushing thickness also contribute increasing durability.

Reinforced arm-end boss and arm cylinder mounting bracket provides higher durability.
Protection plate with 5-square bars also enhances reliability in heavy duty operation.

The R-bucket is made of wear resisting steel, and reshaped with side shrouds, cutting-edge shrouds, and large bucket teeth for enhanced durability.
Easily replaceable lateral wear plates help reduce downtime.
The limestone bucket has similar features except number of side shrouds and size of tooth.

The reinforced travel motor cover with square bars and reinforced travel guard protect travel motor from damage by stone projectiles.

Rigid structure of side frame withstands frequent shock caused by rock hitting.

Track under cover protects travel pipings and hoses.

On the R-specification machine, full track guards are provided standard. Full track guards protect track links and lower rollers from damage and deformation. Moreover, they also keep out stones, preventing overload to the undercarriage to reduce wear and damage.
