A STROKE DELIMBER THAT’S A STROKE OF GENIUS.

The new PD5500M delimber represents the best of both worlds: the design integrity of industry leading Pierce and Denharco stroke delimbers, plus the genius of new cutting edge processing technology.

Introducing wireless communication! Instead of transmitting information through a cable that can easily be damaged, send it right to the head wirelessly. The PD5500M has even more features to help you work safely and productively. Including a safe and simple cab-operated transport system. A hydraulic wedge locking system for added engagement between tunnel and carriage. Curtain-style hose hangers minimize hose damage. And, LED work lights illuminate your work zone.

Maximum value. Minimum waste. Premium design.
That’s the PD5500M.

INTRODUCING THE ZERO 5 MEASURING SYSTEM.

Thanks to its exclusive Zero 5 measuring system, the PD5500M offers superior measuring quality. Now you can get more value —and less waste—out of each log. That’s a smarter way to work, by any measure.

Pierce Z5 Measuring System

INCLUDES
• Danfoss Controller full-scale measuring system
• Durable 6.5” glare-resistant, color display
• Head controller
• Cab controller
• Suregrip control handles
• Photocells located in tunnel
• Solid state electrical components
• Wireless technology between cab and head

FEATURES
• Unobtrusive monitor size doesn’t get in the way of the work ahead
• Instantaneous boot up time
• Real-time length & diameter read-out
• ‘Stop-on-mark’ technology eliminates searching
• Real-time tail swing display
• Measuring is initiated by either ‘FIND-END’, butt plate or making a butt cut
• Built-in, protected photocells for ‘FIND-END’ measuring
• Programmable for 3 different operators
• Easily programmable bucking lists and button functionalities
• Service menus and real-time diagnostic troubleshooting, calibrations and settings
• Simple adjustments optimize efficiency in various working conditions
• Simple and intuitive navigation throughout system
• Production Monitoring: Measure stem count and production values
• Dust and submersion protection
• –40ºF – 158ºF rating

LENGTH PRESETS
Use presets to gain speed, consistency and production by allowing the measuring system to do all the thinking. Take advantage of up to 10 different lengths for 10 different species. Simply select LENGTH and the PD5500M goes to mark. And, if necessary, change length or species on the fly.

SOFT CLAMP
Delimb arm pressure adjusts in both directions based on stem diameter allowing for a cleaner log. In larger stems, the PD5500M recognizes the need for increased pressure and automatically supplies the delimb arms maximum pressure.

SCALE FACTOR
Calibrated scale factor allows for consistent and accurate results, regardless of species.

SAW TO SAW
Saw to saw measuring capability saves rehandling with the butt saw positioned behind hold arms.

WHY A PIERCE DELIMBER IS WORTH EVERY BUCK.

If you work in various wood species, sizes, and weights, a Pierce stroke delimber makes perfect sense. It’s more efficient than a processing head in big wood applications, has a longer life span and boosts productivity with multi-stem processing and optimizes log utilization. When you factor in the rehandling time you save plus the amount of abuse it can take, a Pierce delimber practically pays for itself.

*Includes: Top and butt saws, butt plate, transport positioning, hoist cylinders. Features and technical data may vary without notice.
