Side Mounted Log Thumper
The most expensive and sophisticated scanning an optimizing equipment is useless if you cannot hold the log steady through the manufacturing process. There is no more stable and efficient platform for scanning and processing timber than an ASM Sharp Chan System. Accurate lumber is valuable lumber, pure and simple.
ASM has invested over a million dollars in precision CNC manufacturing equipment so that we can produce the most accurate and consistent sharp chain possible. While others may try to reduce costs by outsourcing their machining work, we know the only way to get the job done right is to do it yourself.
ASM manufactures sharp chain systems for new installations and also retrofit installations. Our retrofit kits are available to fit almost every brand of sharp chain system. By retro fitting your old sharp chain system with an ASM system you can increase recovery, reduce maintenance and down time, and take advantage of ASM's extensive replacement parts inventory. ASM can ship most replacement chain on the save day it is ordered.
ASM is known world wide for our high quality durable and accurate sharp chain. It's no accident that ASM has more sharp chain systems running than anyone else. ASM Sharp chain is precision made, economical to operate and backed up by a rock solid warranty and service program.
Three chain widths to choose from, 2 1/2", 3", and 3 1/4".
Investment cast, high strength alloy Dog Links are heat-treated and precision machined. ASM's machining procedure includes the critical connector link mounting surface area. Each Dog Link is equipped with two vertical spikes, which can be refurbished using common welding and grinding techniques.
ASM's vertical spike design allows the log to be impaled onto the log with less force. Less impact force at the loading area allows the log to be removed easier, and with less fiber damage after it's been processed.
Connector links are precision machined from a billet of high strength heat-treated alloy. ASM's multi-step machining procedure finishes out all the mating surfacesof the connector link. A precise fit between the connector link and the dog link is essential for distributing lateral forces along several sections of chain. High lateral forces are imposed on the chain while passing through the chipping and cutting area.
Sharp Chain Track:
The sharp chain rides on a wear resistant bar. This wear bar is machined and keyed on the bottom to mate with the supporting track. A center guide bar mounts into a central grove, which is machined in the top of the wear bar. Once the final installation and alignment is complete, the wear bar and the center guide bar can be replaced easily without realigning the entire support track.
ASM wear bars and guide bars are manufactured in 12-foot long sections. Longer sections minimize connecting joints to provide a smoother, stronger guide system. Longer replaceable sections also help to simplify installation.
Sharp Chain Sprockets:
ASM's large-scale CNC machining capabilities allow us to manufacture our sharp chain sprockets with fully machine referenced running surfaces. Machining the sprocket as a complete unit produces a smoother running, better mating, chain and sprocket system.
Chain Guide Anvils:
Every ASM sharp chain system comes complete with one pair of Side Guide Anvils. These Side Guide Anvils provide extra lateral support in the chipping and sawing area. ASM Anvils are fully adjustable and do not require the use of shims.
Precision Sharp Chain Lube System:
The ASM Series 513 high pressure chain lube system meters out the precise amount of lubricating oil needed to ensure maximum chain life without wasting oil. Approximately one gallon of lube oil per hour is applied at critical points on the Sharp Chain System. The lube system is activated* on timed intervals, which are synchronized to the chain running speed and operating time. The lube system applies oil only when chain is actually moving, thus conserving lube oil and eliminating unnecessary clean up.
* Lube oil pump- is activated by the customers PLC system.
Sharp Chain Chipper/Canter
The ASM Series 650 Canter is an extremely precise and solidly built machine packed with many built in values. Our low maintenance, high strength design is easy to maintain and economical to operate.
ASM's exclusive shear pin style arbor bearing mount, provides a rock solid support platform. The ASM design will not allow the chip head and arbor assembly to move forward or backward. This design makes adjustments of the lead-in a breeze, with no possibility of loosing the horizontal reverence point.
Canter head arbors are machined from aircraft quality high strength alloy shafting.
Arbor bearings are oversized tapered roller bearings.
Round way mounting clamps and linear bearings are machined and keyed to match the main support frame and the canter box. This eliminates the need for realignment during maintenance.
The main support base is constructed from W12 X 50# steel beam, fully welded to form a super strong ladder style frame.
The canter boxes are constructed from 1-1/4" and 1-1/2" steel plate, which creates an extra rigid arbor support system that can stand up to years of use and abuse.
To increase positioning accuracy and eliminate backlash, each linear position cylinder is mounted using precision machined and keyed trunnion and rod end mounts. Also, the spherical rod end connecting pins are anchored using precision locking ring assemblies.
Canter head guards and chip chutes are fabricated using super durable T-1 alloy plate for years of durability.
Our Log Charging System is designed to be fast, simple and tough. It features a closed-loop feedback system that produces an extremely quick yet smooth loading action. This not only reduces process times, it also minimizes stress to the mechanical and structural components. To further enhance durability, we've overbuilt it with a variety of heavy duty features including a thick-walled mechanical tubing frame, oversized roller bearings, and turn rolls fabricated from schedule 160 pipe. It can be installed with almost any type of sharp chain system.
