Cat improves feller-buncher; introduces new thinning sawhead |
|
Caterpillar
Forest Products has upgraded the hydraulic system and made other
enhancements to improve performance of the 173 hp Prentice 2470, the
190 hp Prentice 2570 and the 220 hp Prentice 2670 wheel feller
bunchers.
 The company also recently made enhancements to the Prentice SH-50
bunching saw and is introducing the Prentice SC-57, a new center post
saw. Together the upgraded carrier and sawheads greatly improve the
productivity and reliability of the Prentice feller buncher system.
The
saw pump flow capacity in the feller bunchers has been increased,
resulting in a 15% improvement in saw recovery time on the Prentice
2570 and a 6% improvement in the Prentice 2670. Multi-functioning, an
advantage of Prentice wheel feller bunchers, has been enhanced with
improvements to the front control valve.
Simultaneous lift-tilt and
lift-steer functions are over 60% faster than major competitive
machines. Additional adjustments provide better acceleration and faster
ground speed. Operators will notice more power on hills, wet ground and
rough terrain.
Hydraulic hoses have been improved to protect them
from damage and reduce wear. Hoses are longer and made of an
abrasion-resistant material designed to withstand abuse. Extreme-duty
rubber tube covers provide additional protection to the lift arm hoses.
The covers reduce downtime by deflecting impact to the hoses and
preventing friction damage from debris between the hoses.
In
addition, the hydraulic return hose that crosses the center section of
the carrier has been changed to a smaller diameter and is wrapped in a
plastic coil. The smaller hose lasts longer because it is more flexible
and better protected.
To make getting in and out of the cab easier,
the rubber belt step has been replaced with a rigid, fixed step. Other
enhancements include button head bolts to prevent wear on hoses and
expander pins for cab mounts to reduce cab noise.
The Cummins QSB 6.7L Tier III-compliant engine powers Prentice wheel feller bunchers.
