Cat® trailer-mount knuckleboom loaders feature hydraulic systems that provides smooth performance and fuel efficiency. High swing torque, swing speed and lift capacity reduce cycle times and lower cost per ton. The heavy-duty booms and structures provide reliable operation and reduce service costs. Spacious work stations, excellent visibility, and ergonomic controls reduce operator fatigue, resulting in a more productive shift. A wide range of machine sizes with optional factory installed hydraulic packages are available to increase loader utilization. Options include bar slasher, circle saw slasher, delimber, carrier and grapple saw.

Factory installed hydraulic packages increase job site performance and versatility

BENEFITS AND FEATURES

Cat knuckleboom loader hydraulic systems are designed to satisfy the productivity demands of loggers. The 529 is equipped with a simple open-center hydraulic system with a triple section gear pump supplying the flow. This system is time tested and provides good performance and provides many different types of option packages, such as carrier hydraulics for millyard mobility. The 529 features a unique “flow-on-demand” hydraulic system for the subframe hydraulic components like the stabilizers, slasher or delimber. This system directs flow and pressure to the subframe systems only when required for activating a function. This results in improved hydraulic efficiency, reduced heat and lower overall system horsepower demand when compared to a standard open-center system.

Hydraulic Packages

A complete factory installed timber merchandising system

BENEFITS AND FEATURES

The Delimber/Slasher (DS) package is a complete factory installed timber merchandising system consisting of a knuckleboom loader and grapple, trailer with trailer-mounted delimber and an optional ground saw slasher and is available with all delimbing capable loaders - the 529, 559B, 569 and 579. The structural design on these loaders is proven to provide long life in punishing, pull-through delimbing applications. A three-knife CTR 320 is standard on the package, or a four-knife CTR 426 pull-through delimber is available as an option. These delimbers are designed to allow quick, easy loading of trees and produce clean, delimbed stems in a flash. These delimbers also have central lubrication banks and ground-level oil fill for quick, easy service. An automatic chain tensioner simplifies maintenance and extends bar and chain life. The standard delimbing trailer is built with structural reinforcing in critical areas for durability. This trailer features a roll-up gear for transport and a swing down delimbing foot for operation. The optional delimbing trailer features a hydraulically adjustable landing gear that is adjustable from in cab controls. This feature allows the operator to quickly position the loader in a proper operating position, providing more production capability. Knuckleboom Loader grapples are available in a wide variety of rotator types, jaw sizes and jaw configurations to suit a variety of material handling applications. The CTR 107 Slasher is optional for the DS package. A load-sensing saw feed system delivers smooth, fast cutting cycles. This slasher is available in multiple bunk styles and can be customized for specific log-lengths.
