Specially engineered 4-post VRC lifts odd
sized carts that carry fragile aircraft wing parts up 20' to a mezzanine. Carriage had to
accommodate a shallow floor pit and had to be built with asymmetrical bracing to provide
less than I" of deflection. Carriage measures 10' x 40' and is equipped with solid
steel guards to withstand impact of tow trucks and carts while they are backed into
position onto lift. VRC moves entire load (tow truck, cart and wing parts) 10 times per
day up to mezzanine.
Fully automated, high speed system designed
to catch large paper rolls that are discharged from a paper machine and transfer rolls
down to a shipping area. Solution had to meet high throughput, high frequency, heavy load
requirements (9000 lb. rolls. 30 rolls per hour. 24 hours per day. 350 days per year). VRC
is equipped with a cushioning device to catch paper rolls and a customized V-shaped
carriage that tilts to load and unload rolls. Lift is an integral part of the paper
production line, designed to run round the clock, With no downtime.
Company needed to assemble extremely large,
heavy fuel cell components and solve related vertical lifting problems. Pflow designed a
system that incorporates two vertical material handling devices. Lift #1, (shown above),
which incorporates a screw lift mechanism, lowers a 90,000 lb. piece below grade level.
Lift #2 lifts a 20,000 lb. piece, traverses the piece sideways and then lowers it on top
the 90,000 lb. piece. After the two elements are assembled together, Lift #1 then raises
the resulting 110,000 lb. load back to grade level for shipping.
30,000 lb. capacity, 4-post VRC custom
designed to raise a 24,000 lb. scrap charge bucket, mounted on a transfer car, to an
elevated runway track. Charge bucket is then moved horizontally on the runway track to any
one of three induction melting furnaces. Scrap load is then automatically discharged into
a furnace charge car. After load is discharged, charge bucket is returned to scrap make-up
area for reloading. System is operational 16 hours per day. During operation, a scrap load
is lifted and moved every 6 minutes.
