Installation & Startup


install

Installation and setup should not be complicated. Thats why we strive to make it as simple as possible. Prior to shipment, we quality check every order, custom crate (if applicable) and attach specific installation manuals in case you have any questions. Typically, our basic products come crated ready for use, however our more sophisticated products require minimal on-site support. For those that require the on-site support, we schedule a time for the units to be installed and one of our service technicians will install and set it up so that you are up and running in no time.

  • Flexible Gravity Conveyors

    Most NestaFlex® gravity conveyors are packaged to protect the unit during normal shipping, storage and handling (Some special conveyors are shipped fully assembled and rolled onto the trailer. Make sure to remove blocks, unlock brakes on casters and carefully roll conveyors off the trailer). Before the unit is unpacked, inspect the packaging for any signs of shipping damage. If possible, record any suspected shipping damage with a camera. Report anything missing or any damage in writing to the shipper and your FMH Conveyors representative.

    1. Uncrate and inspect the NestaFlex gravity conveyor.
    2. Unlock any locking casters, remove any ties securing the conveyor to the pallet and carefully roll the conveyor off the pallet.
    3. If you have an extended length gravity conveyor that was shipped in multiple cartons, assembly is required before using the conveyor. Instructions are included with the conveyor sections for assembly.   This will involve either making a hardware connection at a special bracket or assembling shafts, skates, and spacers to merge the unfinished ends. This is important to the integrity and proper function of the conveyors. If this connection is not completed, sections of the conveyor will be unsupported and void the warranty.
    4. To move the conveyor, unlock the locking casters and carefully push the conveyor into the desired location, being careful not to place hands at pinch point locations, such as near the side link assemblies.
    5. Lock all locking casters once the conveyor has been moved to the desired location. This is especially important in areas where the floors are sloped.
    6. If you have two or more gravity conveyors and are using them together, simply push the conveyors together in the desired orientation and engage the Couplers (hooks) onto the Coupler Receiver or axle of the next conveyor.
    7. Conveyors with a Carton Stop at the end of Discharge is shipped in the down position. To engage the stop, rotate the stop to its up position. Slide the stop down to engage on the upper axle.
    8. All conveyor heights are fixed on the NestaFlex gravity 376FL and 376PL to provide the best gravity slope condition and should not need to be adjusted. For all other NestaFlex gravity products, heights are adjustable with hand knobs.
    9. To expand or contract the conveyor, unlock the locking casters and grasp the conveyor by the handles located on the side of the legs. Pull or push on the handles to expand or contract the conveyor. Be sure to lock locking casters after the conveyor is in the desired position.
  • Flexible Powered Conveyors
    1. Unpack the BestFlex Power Conveyor and inspect for possible damage that may have occurred during shipping. Pay particular attention to the wiring to ensure that no wires are pulled loose or damaged in any way. If you find any damage, contact the factory before applying power to the conveyor.
    2. Make sure all Start/Stop push-buttons are in the STOP position (there will be one at each end of the conveyor.)
    3. Roll the unit into position. If applicable, use the connect hooks to attach the Best/Flex to a rigid conveyor.
    4. Plug the power cord into a 115VAC grounded
    5. Release all Start/Stop push-buttons (a single Start/Stop push-button that has the Stop button depressed will prevent the conveyor from running.) There may be a stand-alone motor motor controller mounted near the middle of the unit. If this is the case, make sure its switch is in the “On” position. All switches must be in the “Start”, “Run”, or “On” position.
    6. Adjust the speed of the conveyor to suit the application. Adjust the speed by turning the potentiometer. Depending on the unit configuration, the potentiometer will either be located on the main power enclosure or the motor controller mounted near the middle of the conveyor.
    7. Begin placing packages on the conveyor. They will travel to the last available zone and stop until packages are removed from the discharge end.
  • Rigid Belt Drive-Out Conveyors
    1. Upon arrival all conveyors will be secured with wood blocks mounted to the trailer floor.
    2. All wood blocks must be removed prior to moving the conveyors.
    3. Warning: Conveyors must not be picked up utilizing forks on the rear of the unit. Failure to adhere to this warning may cause damage to the main electrical panel on the back of the unit, or the electrical connections coming into this panel. This damage will not be covered under warranty.
    4. To unload, the unit may be either manually pushed from the front of the conveyor, or by utilizing a lifting strap placed around the rear frame of the conveyor and attached to a forklift. If using the strap method, make sure that the strap does not come in contact with any electrical wiring under the conveyor.
    5. The steering actuator on the front axle of the conveyor has been disconnected for ease of movement. When using either unloading method, someone must manually steer the front of the unit to prevent damage to the front control panel.

    Installation should only be performed by FMH Conveyors Installers or qualified personnel, and must be completed in accordance with all applicable codes and regulations.

    Belt Installation and Tracking

    Unroll the belt, PVC coating side up, around the tail pulley and over the idler rollers. Run belt over the snub roller and around the drive roll. Align the seam near the center of the conveyor frame.
    Pull the belt together to engage the lacing and install the pin.

    There are two permanent marks in the center of the belt width approximately 20 feet back from the lacing and 10 feet apart. Find these marks and take an exact measurement between them. Add .375” (3/8”) to the measurement. Example(measured 119 9/16” + 3/8” = 119 15/16). For proper tension, adjust the tail pulley so the distance between the two marks is equal to the sum of the measured dimension and 3/8”. To insure the tail pulley is square, be sure both tail pulley blocks are equal distance from the rear of the conveyor frame. After tracking the belt, check the dimension between the marks to make sure proper tension is still in the belt. If the dimension has changed, adjust accordingly and recheck for proper tracking.
    With the belt installed, begin the tracking procedure. The drive roll should be parallel to the snub roller. The snub roller should be locked into place. All idler rollers are square to the frame.

    Start the belt. Watch to see which side the belt wants to run to and also how quickly it does so. Shut off the conveyor. Begin belt tracking by adjusting the first idler from the tail. Loosen the bolts on the idler bracket and angle the roller to correct the belt travel. The roller will steer the belt toward the uphill side of the roller (Uphill refers to the belt travel direction). If further correction is necessary, proceed to adjust the first idler from the front, then the two in the center of the conveyor, in that order. If adjusting the idlers cannot solve the tracking problem, the tail pulley may have to be adjusted slightly.
    Adjusting the idler rollers will solve most all of the belt tracking problems. The belt should run straight and on the center of the slider bed. Practice and experience will speed up the belt tracking process.
