  • Page 28: Assembly

    Assembly Please check the foundation and the transport direction (location of inlet and outlet), before starting the assembly. It is important to read these instructions carefully before starting the assembly. Check that there is sufficient space available. Attention! Before starting the assembly work, check that the required safety equipment is at disposal, e.g. work gloves, safety footwear, helmet, safety glasses and a lifeline, if necessary.

  • Page 29: Sealing

    AGRO Sealing All the joints must be sealed with a sealing compound in order to avoid dust and moisture nuisance. The sealer must be applied at the flanges inside the holes. After sealing the joints must be bolted together. Silicone | 29 www.jema.as...

  • Page 35: Fitting Of Gear Motor

    AGRO Gear motor assembly Fit the motor and gear on the drive shaft (see below drawing). The engine can be fitted in parallel or traversely on the machine. Important! The breather on the gear must always be fitted in the top position. TF63B gear 2,2 - 3,0 kW TF90B gear 4,0 - 5,5 kW For maintenance of motor and gear: please see the attached supplier documentation.

  • Page 36: Fitting Of Motor And Pulley Kit

    Fitting the motor and pulley drive • Start by screwing on the motor stand and then fit the internal pulley guard. • Fit the small pulley on the motor shaft and tighten with a screw. • Fit the motor loosely on the stand with 4 bolts without tightening it, screw the clip bolt and tension bolt on the mo- tor stand, and then fit the large pulley on the drive station shaft and tighten it with a screw (remember the Woodruf wedge).

  • Page 37: Elevator Extensions

    AGRO Elevator extensions Fit the elevator extensions with inspection doors to the elevator boot /pivot inlet in a way that provides sufficient space for later assembly of the chain, as this has to be done through the extension/inlet trough opening/access door. Fit the extensions as shown on the drawing (if available).

  • Page 38: Elevator Chain

    Elevator chain The conveyor chain is equipped with rubber slats, and the chain must be fitted in the elevator, before the elevator head with extension is hoisted (see drawing). When the elevator top section with the chain has been lowered into the bottom part, assemble the chain with the enclosed belt lacers.
  • Page 39 AGRO If this is not possible, due to lack of space, insert the chain through the elevator head outle t (see drawing below), insert the complete chain down the channel. Then insert half of the chain into the return channel, so the chain is evenly distributed in both channels. Block the chain with a rope or wire, and pull one end of the chain around the bottom sprocket and lift it up to the inspection door.
  • Page 40 Important! When fitting and tightening the chain on machines with inclinations, always keep the same distance between the slats (pos. A), and always fit one slat for each four chain links(as on drawings below). 40 | www.jema.as...

  • Page 41: Assembly Of Elevator

    AGRO Elevator assembly Always use correct and approved SWL-lifting equipment for the elevator assembly. Read the section “Upon receipt” before starting the assembly work. Before lifting the elevator, the chain must be locked, e.g. with a rope or wire. Unlock the chain before assembly.

  • Page 42: Potential Equalization

    Potential equalization The potential equalization must be carried out according to the current regulations. A label on the elevator head indicates the correct point of the potential equalization. The equalization is important to secure that the machine is metallically connected. The label indicates the potential equalization point for the chain elevator.

  • Page 43: Height Attachment

    AGRO Attachment In order to obtain the maximum stability, it is important to stabilize the elevator vertical position. There must be a distance of maximum 2.0 m from the elevator head to the top attachment, and 4 m between the following fixation points. The angle between the wires and the elevator must be max.

  • Page 44: Support Of Increasing Elevator

    Support of increasing elevator It´s important that the elevator is fixed to ensure stabillity. Max. distance between the support points is 5 meters. Max 5000 44 | www.jema.as...

  • Page 45: Upstart

    AGRO Starting up Before starting to work with the chain elevator, please check that: • All inspection doors are fitted • No work is carried out on/near the machine. • The motor rotation direction is correct. • All bolts are correctly fitted and tightened. • The chain is correctly fitted and adjusted. • The attachment and stability of the chain elevator is correct. • Check after start that no joints are leaking. • If fitted, check for correct tension of the pulley. Elevator stops – faultfinding In case of stops, check first whether the elevator is able to start again, when the relay has cooled.

  • Page 46: Maintenance

    After repair and maintenance the inspection doors and shields must be refitted before the work is continued. Always use original parts only In case that original parts are not used, the warranty becomes void, and JEMA AGRO A/S can no longer be held liable for the EU Declaration of conformity. Gear motor Check the gear as described in the attached supplier documentation.

  • Page 47: Elevator Chain

    AGRO Elevator chain Check that the chain tension is correct. Tighten the belt by using the 12 mm bolts on the top of the elevator head. See drawing for correct procedure. IMPORTANT! When tightening the chain, Max 30° loosen the torque arm. See inspection intervals in the maintenance summary.

  • Page 48: Lubrication Of Bearings

    Lubrication of bearings Important! Always keep the lubrication intervals as stated in the maintenance schedule. It is extremely important to use the correct amount of grease, as too much will damage the sealing of the bearing, which will result in leaks and subsequent overheating of the bearing. Check the amount of grease per grease gun stroke.

  • Page 49: Disposal

    AGRO Disposal The methods of disposal must comply with the current local regulations Warning! The electric supply to the motor must be disconnected during the disassembly. Disassemble the elevator on the floor, if space allows, following the reverse order of the assembly procedure.
