D. ROLLER SCREED ASSEMBLY

2. Description

The WRS 5200 Ride-On Roller Screed is made up of truss sections (Figure 4) which vary in length from 3 to 9 feet. These truss sections support the 6 inch tubing (strike tube) which runs along the front of the machine. This strike tube comes in four different lengths, 8, 14, 16 and 18 feet. By coordinating the truss section and strike tube lengths, various roller screed lengths can be assembled.

Table 2 shows the different combination of truss sections and strike tube lengths to get the desired roller screed length. Dimensions are in feet

PAGE 16 — WRS 5200 RIDE-ON ROLLER SCREED — PARTS MANUAL — REV. #2 (08/09/02)

WRS-5200 — ASSEMBLY INSTRUCTIONS

It is important in the assembly of the roller screed to keep truss sections on the appropriate side. To help with this, each truss section is stamped with a letter and a number. This stamping is located on the top pipe of each section.

For example, L14, would represent left or the power unit end and combine this section (9 feet) with the end section (5 feet), gives you 14 feet. This is the strike tube length. The stamping on the 9 foot truss section would be L14. Examples of the assembly for different screed lengths are shown in Appendix C.

2. Assembly of the Roller Screed

To begin with, bolt together truss sections that match the length of the strike tubes desired. Find the length of roller screed wanted in the Appendix C and match the strike tubes and truss sections. Use 1-1/2” long bolts where 2 joints come together and 1-3/4” long bolts where 3 joints meet. Don’t bolt truss sections from other strike tube lengths together yet.

As an example, the assembly of a 44’ roller screed is shown. First check the Appendix C and find the length of screed wanted. Lay the parts as shown in the drawing out in the assembly area. Assemble the truss sections to match the strike tube lengths. For this screed, the strike tube lengths are 14’, 16’ and 14’. The following Figures, 4, 5 and 6, are the truss sections assembled to match the strike tubes.

Task 1. Assemble right, left and middle truss sections. See Figures 5, 6, and 7.

Figure 5. Right Section 14 Feet

Figure 6. Middle Section 16 Feet

WRS-5200 — ASSEMBLY INSTRUCTIONS

Figure 8. Strike Tube Mount

Task 3.

Take the middle bracket and insert the splined shaft of it into the other end of the strike tube as shown in Figure 9. Slide the middle bracket pins into the section just made.

Figure 7. Left Section 14 Feet

Task 2.

Once the assemblies mentioned above are finished, start on one end, take the strike tube and insert it into the 1-3/8 bearing mounted on the outer plate as shown in Figure 8. The 1-5/8 nut and jam nut should be turned in until they are against the strike tube hub.

Figure 9. Middle Bracket Mount

PAGE 18 — WRS 5200 RIDE-ON ROLLER SCREED — PARTS MANUAL — REV. #2 (08/09/02)

WRS-5200 — ASSEMBLY INSTRUCTIONS

Task 4.

If another middle bracket is not required, go to the next paragraph. Two middle brackets are required for three strike tubes, one for two strike tubes. If another middle bracket is required, insert the middle strike tube into the splined shaft of the middle bracket mentioned above. Assemble the truss sections and middle bracket using the ½ X 1-3/4 bolts. Working your way across, take the next middle bracket and insert the splined shaft into the middle strike tube as shown in Figure 9 & 10.

Figure 10. Middle Section

Task 5

Now go to the other end of the roller screed, take the strike tube there and insert it into the second middle bracket’s splined shaft. As you pull the last 14’ section (Figure 7) into place, insert the end of the strike tube into the bearing as you did in Figure 7. Use ½ x 1-3/4 bolts to bolt the two truss sections and the middle bracket together.

Task 6.

Once the truss sections are together, string the four long hydraulic hoses through the middle of the trusses. Two male and two female quick connects are required at the other end, one male and female of the 5/8” hose and the same for the ½” hose.

Task 7.

Put the tarps on the appropriate section. The section of the tarp where two nylon straps are close together should fit over a truss joint. All tarps were made to full length per section.

The tarp for the right section (13’11”) will have two places for the truss joint. It will have a 4 foot section (which for this set-up will be folded back under the next section of tarp) and a 6 and 3 foot section

The middle tarp (16’) has a place for the truss joint right in the middle.

The left tarp (13’5”) has one truss joint located 4 foot in from the end. For this set-up, the 4 foot section will be folded back under the 9 foot.

The buckles on the tarp should be on the back side (strike tube is on front side) and the tarp drain hole on the bottom when finished.

Task 8.

Two more items need to be added on the outside of the tarps. These are the 50 foot electric cord and the pump lever cable. Before buckling the tarp, put the cable and cord behind enough buckles to hold them in place.

Task 9.

Adjust the 1-5/8” nuts on the strike tubes next to the outer plates so the other end of the strike tube next to the middle bracket is spaced from 1/16 to 1/8.”

WRS 5200 RIDE-ON ROLLER SCREED — PARTS MANUAL— REV. 1# (08/09/02) — PAGE 19

WRS-5200 — ASSEMBLY INSTRUCTIONS

Task 10.

Place the power unit on the appropriate end and the roller screed is ready to use.

D. HANDLING

1. Moving the Machine

WARNING!

DO NOT ATTEMPT TO LIFT THE SCREED FROM THE MIDDLE SECTIONS.

Your Whiteman roller screed was designed to be moved and handled in several ways. Casters that can be lowered are provided to move the machine on and off forms and for moving short distances. When using the casters and moving short distances, the power unit may be left on the roller screed.

⇒

When lifting the roller screed to load for transporting or other purposes, the power unit should be taken off.

⇒

Care should be taken to lift the machine correctly. With a fork lift, one end at a time can be lifted onto the transport. Lifting straps should be placed around the top pipe in the 5’ end sections. Figure 10 illustrates the recommended lifting points.

⇒

Care should These lifting positions are the same for both ends. Attach a lifting strap to one of these points. The safety snap pins in the top turnbuckles of the truss sections are not designed to carry the weight of the machine during lifting. The top of the truss sections should always be kept in compression. Lifting with straps or forks from center sections may damage the machine or bend these pins. Figure 11 shows lifting points A & B. Lifting point “B” can be used with any screed length while lifting point “A” should only be used for screed lengths longer than 32 feet.

If lifting the roller screed is planned for transporting or other reasons, some precautions should be followed.

WARNING!

NEVER TRANSPORT SCREED WITH THE POWER UNIT ON THE MACHINE
