    The KEITH Running Floor II owner's manual contains more detailed information about the system and operation procedures. Direct any questions to KEITH Mfg. Co. or one of our international offices listed on the cover of this manual.

  • Page 4: Drive Unit Compatibility

    Chapter 2 TRAILER PREPARATIONS The trailer requires preparation before the system is installed. Planning ahead for the WALKING FLOOR installation requirements saves significant preparation time, especially when building a new trailer. 2.1 Drive unit compatibility ® There are two styles of Running Floor II drive units.

  • Page 5: Trailer Alignment

    Figure 3 1. AXLE FRAME 25031 2. LANDING GEAR FRAME Figure 4 25028 1. TAPERED FRAME RAIL NOTE: Manufacturers of frameless trailers may want to consider extending their axle rails far enough forward that a frameless drive unit can be installed (extend 2.87m for 255mm stroke, 2.77m for 150mm stroke).

  • Page 6: Bracing

    floor. If there are deviations exceeding 3mm, make corrections. Ensure that the last beam of the trailer at the rear door threshold is level with the cross members. Bracing Trailer bracing prevents warping. Figure 5 25032 1. AXLE FRAME 2. LANDING GEAR FRAME 3.

  • Page 7: Hydraulic Tubing Locations

    2.4 Hydraulic tubing locations Hydraulic pressure, generated by the tractor's wet kit, powers the drive unit. Tubing must connect the drive unit to the tractor. 1. Consider the location of the hydraulic tubing. Chapter 6 provides more information on this subject. A central location is preferable for the quick-couplers in front of the trailer.

  • Page 8: Cross-Members

    1. Compare the trailer cross-member height to the formed cross sills on the drive unit. They should be the same. If they differ, contact KEITH Mfg. Co. or one of our international offices. 2. Check cross-member flange width for proper bearing fit (Figures 9 and 10).
  • Page 9 The bearings are designed to fit flanges smaller than 62mm. If the surface is wider than 62mm standard bearings cannot mount on the top. The bearings can be specially milled to fit a 100mm maximum. Figure 9 25019 25mm x 25mm TUBE Figure 10 25042 1.

  • Page 10: Shimming

    2. Reposition cross-members if necessary. The rearmost cross-member should be mounted a minimum of 450mm inside the trailer doors. The foremost cross-member should be about 450mm away from the front wall. NOTE: Holes for the hydraulic tubing should be made through cross-members before they are mounted on a new trailer.

  • Page 11: Sub-Deck

    SUB-DECK The sub-deck is the structure directly above the cross-members and underneath the floor slats/planks. The sub-deck consists of square steel tubing or U-shaped aluminum profiles. The square tubing mounts on top of the cross-members. Plastic floor bearings connect to the tubing. 3.1 Baffle plate A baffle plate extends forward from the door threshold to prevent material from sifting through the floor when slats/planks are in the forward position.

  • Page 12: Square Tubing

    3.2 Square tubing The proper installation of the square tubing is critical for maintaining drive alignment, floor straightness and for optimal performance of the seal located between the floor slats/planks. Square tubing is usually applied before the drive unit is positioned, unless the drive unit is dropped from above.
  • Page 13 Start at the rear of the trailer. Lay the two outside tubes in the trailer and separate them with spacing jigs. Center the jigs so the tubes are the same distance from the side walls. Lay out the remaining tubes across the width of the trailer, spacing them with jigs.

  • Page 14: End Sub-Deck

    92.71mm Figure 18 25011 92.71mm Figure 19 25010 3.3 End sub-deck The unloading end of the sub-deck needs special attention because the area is fully exposed with the floor slats/planks in the forward position. There are five end sub-deck options: 1) Extended square tube.
  • Page 15 2) Solid steel bar. (25mm x 25mm) This method is recommended for hauling solid waste or other highly abrasive materials. The solid bars meet the square tubing on the last cross-member. 3) Solid aluminum bar. A solid aluminum bar will provide a strong structure at the end when the sub- deck is constructed with aluminum profiles.
  • Page 16 4) T-block. A plastic T-block provides a sliding surface and prevents material from going underneath slats/planks. T-blocks are not recommended for use with highly abrasive materials. 5) NO end sub-deck The absence of an end sub-deck is undesirable because it leaves no support for ends of slats/planks.

  • Page 17: Side Seal Support

    Option 1: Extended steel tubing This sub-deck is installed along with the installation of the rear sub- deck. Weld caps to the tube ends to prevent material from entering. Grind to give a smooth finish. Option 2: Solid steel bar 1.

  • Page 18: Drive Unit

    DRIVE UNIT Drive unit installation in a center frame trailer differs from an installation in a frameless trailer. Chapter 4 examines the two installations separately. 4.1 Center frame trailer 1. Decide on the location of the drive unit. The drive unit should be installed as close to the rear of the trailer as is practical. 2.
  • Page 19 Figure 20 25025 2. Align and level drive unit. Front to rear alignment Center the drive unit in the drive gap. The 25mm x 25mm tubing should extend 50mm past the formed cross sills at each end of the drive unit. The 50mm x 150mm cross -drive tubing should be parallel to trailer cross-members.
  • Page 20 25mm x 25mm Figure 21 25045 Height a. Place plastic bearings on 25mm x 25mm tube at sides and center of trailer at each end of drive area. b. Lay a straight edge from bearing to bearing across the drive. c.

  • Page 21: Frameless Trailer

    Slide the support tubes into position between 150mm x 50mm cross drives and trailer frame rails. Place the tubes where they will support the cross drives over a full stroke. The steel tubes can be shimmed to create a close drive to UHMW fit.
  • Page 22 2. Align and level drive unit. The ends of the formed cross sills should rest on the trailer side rails. Front to rear alignment Butt the tapered drive frame rails tight against the ends of the axle beams (Figures 24 and 25). A transfer plate may be placed between the two beams if a flat surface does not exist on either the drive frame or the axle beam.
  • Page 23 the 25mm x 25mm tube to the top of the drive shoe is critical. Raise or lower the drive unit accordingly.

  • Page 24: Painting

    Figure 27 25034 3. Weld the drive unit in place. Weld according to reference drawing C-10797A. Remember to connect 25mm x 25mm tubing to the drive unit's formed cross sill. 4. Weld bracing to side walls as shown in reference drawing C-10797A. 4.3 Painting The factory paints drive units with gray oxide primer.

  • Page 25: Flooring

    FLOORING After paint dries, the flooring can be installed. The slats/planks slide on plastic bearings. Hold-down bearings mounted at the rear end keep the slats/planks down. The aluminum floor slats/planks are bolted to shoes on the cross drives. 5.1 Slide bearings 1.

  • Page 26: Floor Slats/Planks

    If a wear plate is mounted on one end of the floor slat/plank, cut the surplus off at the opposite side. NOTE: KEITH Mfg. Co. normally performs steps 3-5. 3. Install drive-in wear bearing. See reference drawing D-50625. A. Place all slats/planks on their sides. The side opposite of the seal groove should be facing upward.
  • Page 27 J. Remove the punch tool from the jig and unclamp the jig from the slat/plank. K. If the bearing is not flush with the end of the slat/plank, pound it in the rest of the way using the mallet, until it is flush with the slat/plank. L.
  • Page 28 a. Place the bundle of floor slats/planks on four equally spaced sawhorses. The sawhorses must be strong enough to support the weight of the floor slats/planks. Remove the banding from the bundle. b. Inspect the ends of the floor slats/planks. De-burr the seal groove. Chamfer the outside edge of the floor slat/planks opposite the seal groove.

  • Page 30 Figure 34 Figure 35 d. Apply a 3mm diameter bead of SikaFlex 221 adhesive sealer into the exposed seal groove (Figure 36). The bead should be from the end of the seal to the end of the slat/plank. If using the polyethylene seal (blue) the bead should be 50mm long (Figure 37).
  • Page 31 Figure 37 50mm Figure 38...
  • Page 32 e. Pull the seal flush with the end of the slat/plank. Install the anchor screw (Figure 39). Do not tighten the anchor screw too tightly. Allow the adhesive to dry before finishing the installation of the slat/plank. Figure 39 f. Apply three additional beads of adhesive. The additional beads of adhesive should be 610mm long.
  • Page 33 The additional adhesive is recommended for saw dust and agricultural applications. The additional beads should be used on floor slats/planks #2185, #2188, #2190, and #2203. Complete steps “c”, “d”, and “e” on all the slats/planks in the bundle. Repeat steps “d” and “e” to the opposite end of all of the floor slats/planks. When using a splash seal, install it in the T-slot in the same manner.

  • Page 34: Side Seal

    Figure 42 25021 a. Align the rear end of all slats/planks 12mm from inside of doors and make sure that all cylinders are collapsed to the rear of the trailer. b. Drill holes in the slats/planks from underneath through the drive shoes. (Some holes may need to drilled from above if slats/planks are over frame rails.) c.
  • Page 35 For instructions regarding 6” (152.4mm) flooring, please contact KEITH Mfg. Co. or one of our international offices listed on the cover of this manual. 2. Split slat/plank if necessary. Rip floor slat/plank with a circular saw to fit side wall as closely as possible. This is another reason trailer alignment is critical.

  • Page 38: Front Shield

    When the floor slats/planks are in the rear position, the slide strip must still lie fully on top of the floor slats/planks. 2. Fabricate front shield. (KEITH Mfg. Co. supplies this in most cases.) Form the plate and attach angle steel for support. Rivet the plastic slide strip to the shield.

  • Page 39: Hydraulic Tubing

    HYDRAULIC TUBING Section 2.4 discusses the location of hydraulic tubing. IMPORTANT: All components and tubing must be kept absolutely clean to prevent dirt from entering the system. 1. Determine tube locations and lengths. Keep bends to a minimum. Make all bends with sweeping elbows to reduce heat build up.

  • Page 41: Miscellaneous

    MISCELLANEOUS 7.1 Trailer wires and lines Make sure that wires and lines cannot be damaged by moving parts. Mount them so they cannot rub against other parts. Check proper light and brake performance. 7.2 Caution decals Affix caution decals to the side of the trailer at the location of the drive unit. 7.3 Front guard A front guard should deny access to the underside of the front end of the slats/planks so they cannot shear anything entering from below.

  • Page 42: Trimming A Floor Slat/Plank (After Side Seals Are Installed)

    7.6 Trimming a floor slat/plank (After seal is installed) a. Cut the floor slat/plank to the required length. Do not damage the floor seal. The rear wear strips and front filler strips must be replaced if removed by shortening the floor slat/plank. If there are wear strips or filler strips installed on the slat/plank, it is recommended to cut off the opposite end.
  • Page 43 d. Weld on wear strips or filler strips. Shield the floor seal from weld splatter. Use a heat sink to prevent damage to the floor seal. e. Apply a 3mm diameter bead of SikaFlex 221 adhesive sealer into the exposed seal groove. The bead should be from the end of the seal to the end of the slat/plank.
  • Page 44 g. A 610mm long bead of adhesive sealer is required between the seal and the floor slat/plank (Figure 50). Pull the seal outward to apply the adhesive. Press the seal against the floor slat/plank after applying the adhesive. Allow the adhesive to dry before installing the floor slat/plank.
