The HS420 is designed with your future in mind. A heavy-duty high-quality hydraulic proportional carriage, it is built with the ability to convert linear positioning at a later date. Perfect for start up operations working within tight budgets, it also adds value if sold used, allowing potential buyers to easily get the exact style of carriage desired – even converting to a simple air set if required.
Several options are available to meet your requirements for layout, production, log and cant turning, and maintenance.
Other Hydraulic Setwork Carriages
- Built from heavy-duty, thick-wall structural steel components, precision welded and finished — Rigid, accurate
- Horizontal or Tilt Frame – Meets customer needs, easily integrated into existing systems
- Two to five headblocks set at customer specified spacing – Meets customer needs for log lengths and mixes
- Larger/heavier than the 360 and 380 Series – Longer life, less maintenance, higher production
- Heavy-duty fabricated 3/4” bunks utilize long lasting 5/8” alloy steel wear plates – can be replaced to extend overall carriage life
- Knees are precision fabricated from 1” solid steel bases and two 1/2” side plates – longer lasting, more durable
- Knees attach to bunks with a wrap-around mount for stability – extremely accurate lumber, high durability, less maintenance
- Adjustable, replaceable synthetic wear strips on the top, bottom, and sides of knee mounts – maintains perfect fit, easy maintenance, long life
- Adjustable rack and pinion knee positioning – Precise, eliminates excessive maintenance of chain drives
- 1” Thick T1 alloy steel tong-dogs are center mounted within the knees – Increased accuracy comes from exceptional positioning and security.
