Product Teaser

POWER & ACCURACY THAT’S RIGHT ON THE MONEY, EVERY TIME.


Built strong to handle big timber, other processing tools just don’t measure up to the superior design of Denharco delimbers. Measuring from a lineal steel boom assures you of precision accuracy – and greater efficiency – time after time. Our delimbers shine in large diameter timber, heavy limb applications, irregular logs, multi-stem processing and multiple sorting requirements, guaranteeing that you get the most value out of every stem.

When it comes to working in challenging forest conditions, it pays to have the right equipment for the job. And of course North American made, as is all Pierce & Denharco equipment. Got a tough job? These delimbers can hack it!

THIS PRODUCT LINE FEATURES THESE TECHNOLOGIES :

Finite
Element Analysis

Finite Element Analysis (FEA), combined with computer-aided motion analysis software, allows our design team to eliminate structural “hotspots” where structural strength is critical to the long-term integrity of the product. Learn more.

What does ‘DM 4550’ mean anyway?



.404 vs. 11H?

.404 vs. 11H

.404 BENEFITS:
.404 top saw cuts faster and smoother.

.404 saw systems are more economical in initial purchase cost than 11H.

Auto-tensioning and saw safeties.


11H BENEFITS:
11H saw bars are more robust, resilient and longer lasting than .404. 11H requires less chain sharpening than .404.

Auto-tensioning and saw safeties.

The DM4550’s powerful winch drive system equipped with a variable displacement drive motor provides this Denharco delimber the ability to optimize power and speed according to your momentary needs. The quiet and easy to maintain cable drive system with auto tensioning assures operating precision while minimizing downtime for manual adjustments, and its heavy duty construction makes it comfortable and quiet, no matter the conditions of the stand. Its robust 12”x12” monoboom is made of a special alloy and offers and impressive delimbing reach of over 45’ as well as feed speed of 12 ft/sec.

The DM4550 is equipped with the Intellitec Measuring System which optimizes your production, meeting and exceeding the production expectations of the most demanding forestry expert…you!

TRANSPORT HEIGHT MATRIX








The DT4550 telescopic delimber combines all the heavy duty elements of our flagship DM4550 within a telescopic delimber featuring processing speed of 16 ft/sec and minimum tail-swing for tight landings and work areas. This makes the DT4550, suited for 20-21 metric ton machines, ideal for handing stems in confined spaces.

The DT4550 can be equipped with either topping knives or top saw, as well as 2 available butt saw options, allowing you to configure the delimber to suit your job perfectly. The DT4550 is equipped with our Intellitec Measuring System which is designed to automate the operator’s actions while optimizing your production.

The DMC4150 is designed to suit an entry level processing application, yet without the sacrifice of quality and toughness.

The DMC4150 offers a myriad of saw options to suit virtually all processing applications, a winch drive system that comes equipped with our variable displacement drive motor designed to optimize power and speed according to your momentary demands, and a shorter monoboom allows for operational stability while mounted on the smaller, less expensive 20-21 metric ton carrier class.

The DMC4150 utilizes our controller electrical system for more simplified electrical demands.
