5Why Does CLARK Use I-Channel?
6Why Does CLARK Use I-Channel? Shear Center
Location
7- Nested I-Channel
- Better arrangement of cylinders, chains and
hosing to maximize view window width. - Interlocking rails will not separate if roller
fails. - Can use wider sections without penalty. Stiffer
upright design makes for less deflection and
twisting. - Better connection of tie-bars to rail sections.
8- Nested I-Channel
- Allows use of external side thrust rollers
- Prevents inner rail from spreading rails with
side loads. - Less carriage twisting from side loads.
- Prevents carriage rollers from riding at edge of
flange. - Increased stiffness
- Better resistance to twisting
- Less deflection due to loads
- Longer fatigue life, less wear
9- Silent Staging-Raising
- Cushioning on primary and secondary cylinders
when raising, just prior to full extension. - Oil is trapped and forced to bleed out slowly.
- No clanging during lifting.
- Avoid product damage.
- Longer component life.

OIL
11- Silent Staging-Lowering
- Cushioning on secondary cylinder when lowering,
just prior to full retraction. - Oil is trapped and forced to bleed out slowly,
providing cushioning effect. - No clanging during lowering.
- Avoid product damage.
- Longer component life.
- Not needed on primary cylinder since forks hit
the ground.
12- Silent Staging-Secondary Cylinder- Lowering
Trapped Oil
13- Internally Vented Cylinders
- Seals designed to seep from high pressure to low
pressure. - Keeps fluid on top for cushioning.
- Caution Could run dry if wrong seal used.
- If excessive oil leaks past piston and is trapped
on top side of piston, it will bleed back to
pressure side via one-way valve. - External return to tank not needed.
14- Sealed Canted Rollers
- Roller face in full contact with rail flange.
- Increased contact area, reduces flange stress and
bending. - Radius of roller fits neatly in radius of rail.
- Reduces side-to-side free play.
- Eliminates need for slides or side thrust
rollers. - Reduces rattle.
15- Shimable Rollers
- Can install shims behind roller to adjust
clearance. - Removes free play if wear occurs.
- Oversized Rollers
- Can install oversized rollers to account for
flange face wear. - Retains tight fit.
- Extends life of rail sections.
Shim
16- Negative Drop rails
- Allow rail rollers to be serviced without
removing upright from truck or dismantling
upright. - Lift cylinders are disconnected and rails
lowered to expose rollers for replacement or
shimming. - Minimizes time required to service upright.
17- Large View Window
- Nesting allows space for cylinders, hoses and
chain. - Maintains excellent view window even with 4-hose
internal. - Hoses and chains are over the top of the primary
cylinder for max vision window. - Lift chains share load, side-loading no problem
18 19- Carriage Features
- Six load rollers.
- External and/or internal side-thrust rollers.
- Heavy-duty fork bar sections.
- HSLA steel fork-bars and roller brackets.
20- Six Load Rollers
- Outermost rollers take load when in carrying
position. - Maximum spacing lowers load when load is highest
- Bouncing while traveling.
- Ground level pick-up.
- Innermost rollers take load when upright extended
past free-lift. - Not as much bouncing when upright is extended.
- Allows for competitive lowered heights.
21 22- Side-Thrust Rollers
- Carriages have internal side- thrust rollers,
external or both. - More effective control of carriage under off-set
loading conditions. - Mounted on eccentric shaft that adjusts and locks
into place.
23- Heavy-Duty Fork Bars and Load Roller Brackets
- Made from HSLA steel.
- Massive section size.
- Better impact strength.
- Holds up better in demanding operations.
24Fuel SystemsEPA 2004--EPA 2007
25- EPA 2004 Spark Ignited Engines
- Low Emissions of unburned Hydrocarbons, Oxides of
Nitrogen and Carbon Monoxide - Must meet requirements both new and throughout
3500 hours of use, cannot degrade out of
specification - System must be tamper-proof so that mechanics
cannot readjust and destroy fuel settings

- Similar to 2004 levels of HC Nox, Co during
steady state running. - Must meet requirements during transient
conditions, (acceleration, deceleration, sudden
load applied). - System must be tamper-proof so that mechanics
cannot readjust and destroy fuel settings - Technology not much different from 2004 to 2007
- Venturi systems (Impco, Woodward, Aisan) will
shorten response times to get back to stoich - Major development is in testing to certify.
