Precision and Premium Duty Linear Positioning Carriages

McDonough Carriages are designed with accuracy and ease of maintenance in mind with State-of-the-art features you will only find on a McDonough.

Sizes: 36", 42", and 48" openings. Precision Duty starts from 12,000 pounds and Premium Duty from 20,000 pounds.

Both Premium and Precision Duty Carriages share the same features, other than the Premium being a heavier Carriage.

Options available: Round way knees, 17 degree slant, UHMW cant kickers, Brownsville turner, chain turners, Tong Dog, rail, operators cabs, carriage drives, and setworks.

Advantages to owning a McDonough Carriage:
-Board Dog Carriages are preferred over Tong Dog Carriages because they dog the log faster and are superior to holding a smaller cant.
-Stepped Flat Ways on headblocks allow knee to ride on separate surface than log, to maintain accuracy.
-Flat Ways are split on headblocks creating a 21" front way for less costly and easier replacement.
-Headblock Ways are fully machined, 1.25" thick Kromite for longer wear.
-Knees, headblocks and frame are welded by certified welders and are vibratory stress relieved prior to machining for the most accurate finished product.
-Hydraulic hose is used for all air and hydraulic lines. These hoses have crimped fittings, not push lock, to prevent hoses from blowing off.
-All lubrication lines are steel, not plastic which will become brittle and crack over time.
-All wear strips used are made from Nylatron GSM, which provides better accuracy than UHMW.
-All cylinder ends have replaceable swivel bushings to eliminate binding and cylinder damage.
-Frame is fully boxed and gusseted for added strength, with access holes to critical areas.
-Knees are made from A572 steel, which allows McDonough to use thinner and lighter steel while gaining strength.
-Knee face plates are only 2.5" wide Kromite, to allow more accurate taper sawing.
-All board dogs in knee and Tong Dog are made from T-1 steel for long lasting wear and have 1/32" clearance for accuracy, replaceable by removing one bolt per tooth.
-The functions of dogging the log and cinching it back against the knee are done on round ways for “straight line” simplicity, which prevents binding a linkage style will cause. Long lasting orkot bearings in cinch function.
-16" diameter Vee Wheel and Flat Wheels are either long lasting polymer composite, or T-1 steel hardened to 320/360 Brinell.
-Tong Dog made from 1 1/4" T-1 steel (1.5" on Premium Duty Carriage) with keyed replaceable teeth.
