The press was designed around the MAXRail
combined bearing linear system MX63 LM76,
because of its’ intrinsic strength and cantilever
load capacity. There is enormous strength in all
the moment directions of all of the rail bearing
combinations and this allows for reliable function
and ease of design and manufacturing. LM76
Linear Motion was very helpful in supplying specifications, packaging and shipping these
heavy steel rails all the way up to northern Alberta." 

The press functions by pressing in one direction- that is the upper
clamps which come in contact with the inside radius of the strands in
the truss, and a support mechanism that contains the plywood bulkheads
that supply the shape and frame of the trusses.  The bulkhead supports,
work in submission to the clamp jaws.  As the trusses are pressed, the
bulkhead supports resist motion and thus create a clamping action
between the clamping jaws pushing down and the bulkheads moving
down in resistance.

Last year I received a call from Alberta Machine's Jerome
Cupido. He informed me that he was designing a totally automated
system for his customer and that it would be employed in making roof
truss sections for Vancouver's 2010 Olympic Richmond Skate Oval
Facility. This was a time sensitive system and everything had to work on schedule. We decided that LM76's MAX rail Combined Bearing would
take the huge moment forces developed by this system. Our MX63
bearings are capable of 40,000#'s of radial force. As you can see, this novel approach is very successful. Moreover, the entire system was supplied on time and on budget. For more on Alberta Machine, one
of the most innovative design/build companies we have had the
pleasure of working with,please call: Alberta Machine
