SCRAPER SYSTEMS Hog Slat Inc. Newton Grove, NC USA February 2022 2 Basic Layout and Dimension Requirements: Figure 1 - Pit Layout Figure 2
SCRAPER SYSTEMS Hog Slat Inc. Newton Grove, NC USA February 2022 3 Scraper Clearances Approximately 3” clearance is required between the end of the scraper and the pit wall. System Recommendations Number of Pits Maximum Cable Length 4 600ft 3 800ft 2 1000ft 1 1200ft The drive unit and corner wheel assemblies of the pit scraper system must be protected from freezing. Corner wheels, steel cable and metal parts may seize due to freezing. Avoid and remove any obstruction to the cable system, corner wheel assemblies and scrapers. It is not recommended to use the scraper system in an open pit with animals present. Hog Slat is not liable for injury to animals.
SCRAPER SYSTEMS Hog Slat Inc. Newton Grove, NC USA February 2022 4 Construction of the Pit To ensure satisfactory operation of the scraper system, the depth of the pit must be 8” minimum below the slat floor. Recommended depth of the pit is 12”. Interior walls of the pit must be free of any voids or protrusions which could cause the scraper to bind during operation. Pit bottom must be concrete. For retrofitting into existing pits, all cracks, voids and seams must be repaired with suitable concrete patch repair materials. Marking Gutters Find and mark center line of each gutter with a chalk line. On two-gutter systems, mark the crossovers also as the lines will intersect each other showing the location where the corner wheel assemblies are to be installed. Install Power Unit and Corner Wheels According to your system layout design plan (see Figure 1), place the power unit and corner wheel assemblies in their approximate locations. Before fastening these units in place, be sure to align them properly so that the cable will be in the center of the pit. The corner wheels should be installed on the opposite end of the building from the power unit. On single-gutter units the corner wheel can be mounted horizontally or vertically. Install the non-adjustable corner wheels on the same end as the power unit. Locate the corner wheels as shown on the drawing. See Figure 1. The power unit can be installed in several positions according to your gutter width and building design. Position the cable drive cable pulley in line with the cable and secure the power unit to the floor or wall with adjustable brackets. Normally, two wraps of the cable is sufficient to pull the blades. Always use stainless steel cable. Remove gearbox vent plug before operating system. The power unit and corner wheel assemblies should be secured to the floor and /or walls with lag bolts and cement anchors. Increasing or decreasing cable tension can be achieved by adjusting the power unit adjustment bolt.
SCRAPER SYSTEMS Hog Slat Inc. Newton Grove, NC USA February 2022 5 Install Scrapers Install the scraper(s) in the gutter. On single-gutter installations, position the scraper in the end opposite the power unit and as close to the corner wheel as possible. If two scrapers are used, position one in each gutter and at opposite ends of the gutter. One should be at the corner wheel and the other at the dump point near the power unit. The blades are designed to remove an adequate amount of manure without overloading the system. (Part failures due to overloading the system are not considered “defective” under warranty) The scraper blade is designed to move manure to a dump point. If the scraper does not move freely though the pit area and more clearance is needed, cut an equal amount off each end of the scraper. Leave it long enough to clean the pit floor. Install the Stainless Steel Cable Use only 5/16” -7x19 stainless steel cable in the system. Hog Slat part # 617276 Feed the cable though the power unit and corner wheels. Attach the cable to the cable bracket on the scraper blade leaving 3-4” from the point where you want the blade to stop. Pull excess cable between the blade and the power unit though the power unit. Thread the cable through the scraper system as shown in Figure 1. No cable clamps or connectors can pass through the corner wheels or power unit drive pulley. Cable Adjustment Remove the cable clamps and the cable from the scraper. Pull the cable snug and lap the cable ends one on top of the other on the cable bracket and install two cable clamps (do not tighten the clamps). Use a come-a-long or suitable cable-tightening device to tighten cables (do not over tighten the cableapproximately 200# tension is all that is necessary on the cable). Tighten the cable clamps. Turn the power unit by hand to pull the blade up to the discharge point. Go over to opposite pit and to the opposite end of the building and position the second scraper at the point at which the blade will stop in reverse. Cut a piece of cable approximately 12” long to lay over top of continuous cable going across the scraper. Attach to cable scraper with clamps and tighten. To figure required cable lengths, add the combined lengths of all pits, plus the return side of a single or odd pit if used, plus the total length of all crossovers, plus a minimum of 5 ft. to lace the power unit. It is best to overestimate the lengths as spliced cable cannot be used to go through the power unit or corner wheels. After the cable is connected to the scrapers and run through the power unit, test the unit to see if it will pull the scrapers.
SCRAPER SYSTEMS Hog Slat Inc. Newton Grove, NC USA February 2022 6 Since cable cannot be spliced and run through the power unit, replacement is costly. It pays to treat them carefully. Here are some precautions: A. Don’t overly stress cable by trying to pull large loads. The cable has enough strength to pull most any load the unit will develop, but overly stressing will cause other parts to deteriorate or fail. (As mentioned before, this situation is not covered under warranty. B. On installations where cables go through a passage under the floor or behind a wall, be sure cable does not drag over sharp edges. Use PVC pipe or any other smooth object to go through passages or walls for cable routing. Testing Turn on the unit to see if it will pull the scraper under a no-load condition. If it will not, you must determine how much slack you have and perhaps shorten the cable at the scraper blade connection. If you do not need more tension to get the scraper to operate, adjust the adjustment on the power unit bracket or corner wheels at this time. Tighten only enough to make the scraper move in both directions. After the unit has run a few days, it may be necessary to adjust cable tension again, but only take up enough slack to keep the pulley from slipping. Too much tension can damage the cable and equipment. If you have the adjustment fully taken up, you will need to loosen up and re-tighten the cable at the scraper. Then tighten the tension again. Only tighten it enough to get it to pull the load of manure with the frequency you have chosen for your cleaning schedule. The cable should be tight enough to pull a normal load. Maintenance Periodically (8 weeks or between pig transition): Check all bolts on the power unit, including the floor mounting bolts. Check all cable clamps. Check cable tension. Clean and inspect scraper blades for excessive wear and damage. Check gearbox oil level. Use SAE 90 gear oil.
SCRAPER SYSTEMS Hog Slat Inc. Newton Grove, NC USA February 2022 7 Trouble shooting Power unit will not run: Check fuse or circuit breaker. Have electrician check components in the control panel to make sure all components operate. Check for loose wires. Check for loose belt. Cable slipping: Adjust the cable tension. Wiring Instructions Note: Scraper is to be wired in accordance with all local, state and national wiring codes. All wiring sizes and fuse capacities are to be sized according to national electrical code specifications or other applicable regulations. The recommended switch for the Hog Slat Scraper Systems is a “Maintained” Forward-Off-Reverse 20 amp either 1-Phase of 3-Phase switch depending on electrical supply. “Maintained” means motor or Scraper System stays turned on until operator physically turns system off. Caution Scraper System should never be left unattended during operation. Serious physical injury or system damage could result from a Scraper System being unattended. Check and make sure the motor voltage corresponds to the supply voltage. 1-Phase 4-Wire Motor Connection The connection diagram below is for a typical connection of a 1-phase 4 wire motor.
