Type Plate The type plated is fitted on the drive station. Type: XXXXX Model: XXXX JEMA AGRO A/S Sahl, DK-8850 Bjerringbro tlf. +45 86 68 16 55 År: XXXX www.jema.as Construction The chain elevator type CFG 20/CFG 40 is made up of standard elements, which can be combined and easily integrated into all grain conveyor systems. It is characterized by a large capacity and compact dimensions. Both elevators work efficiently in all positions and compared to their capacity (output), they both have low power consumption. The chain elevator is made of galvanized steel, which makes it perfectly suited for outdoor use. It is furthermore fitted with a high quality roller chain with bolted rubber flights. The chain elevator can be combined for both vertical and horizontal transport by using side augers in troughs. These are driven from the elevator bottom shaft, so both elevator and side auger are driven by the same motor, alternatively the side auger can by driven separately by a directly connected gear motor.

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. This equipment is not included as standard. Assemble the elevator in two parts, top and bottom section: • The bottom part consists of the elevator boot, 2.5 m extension with inspection door (the assembly of the chain is made through this door) and elevator extensions corresponding to half the height of the elevator. • The top section consists of the elevator head and the remaining number of extensions, and must be assembled with the chain - remember that the overlapping plate must be facing downward. • The elevator extensions with inspection doors must be fitted at the elevator base plate, and the end with inspection door in the return channel must be facing downward. Assemble the top- and bottom section, once the individual sections have been assembled.
Sealing All the joints must be sealed with a sealing compound in order to avoid dust and moisture nui- sance. The sealer must be applied at the flanges inside the holes. After sealing the joints must be bolted together. Silicone...

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.
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 motor stand, and then fit the large pulley on the drive station shaft and tighten it with a screw (remember the Woodruf wedge). • Offset the motor in the slotted holes of the support, until the pulley sheaves are parallel. Tighten the motor bolts. • Move the motor stand towards the conveyor by loosening the tension bolt, and fit the pulleys. Tighten the pulleys with the tension bolt and the clip bolt. • Finally fit the external pulley guard. The belt tensioning is correct when the belt deflection is 10-15 mm (see drawing). 10-15mm Important! The belt needs retightening after the first 24 hours, and then according to the maintenance schedule. NOTE! Do no use tools to force the pulleys onto the sheaves.
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). The elevator must be constantly secured during the fitting – see section “Height attachment”.
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
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. Check the chain length (loosen the tensions bolts on the elevator head). If the chain needs shortening, it can be disassembled with a thin chisel. Assemble the chain – use only new clips in the connector links. Tighten the chains with the bolts on the elevator heads with a few mm play at the lower sprocket. Tension bolts...
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).
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. Assemble the chain with the chain connector, when the elevator top and bottom part have been fitted (see drawing). Important! Remember to fit all inspection doors after assembly.
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. Potential equalization...
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. 45°, and 90° between the wires (see below drawings). Max 2000 45° Max 4000 90° Pos.

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. If this is possible, the fault is either caused by low adjustment of the relay or lack of motor capacity. Check if the motor is correctly connected by the electrician. If the elevator is still not able to start without being emptied of material, check whether the return tube (downward passage) on the conveyor is filled with material in the first section (open the inspection door). In this case the fault is due to blockage of the elevator drain (drain tubes too small or insufficient slope) or caused by stops further along in the transport system.
Maintenance Please see the maintenance summary and the attached supplier documentation for cleaning- and maintenance intervals. Warning! • During cleaning and maintenance work, the electric supply for the chain elevator must be disconnected and secured against accidental reconnection. • 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.
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. Rubber slats Defective or worn rubber slats must be replaced. See the maintenance summary.
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 seal- ing of the bearing, which will result in leaks and subsequent overheating of the bearing. Check the amount of grease per grease gun stroke. Elevator head Lubricate the 2 bearings in the elevator head with 3.0 g grease as described in the maintenance summary. Elevator boot Check, and if necessary, change the two bearings in the elevator boot after 8000 hrs of opera- tion. Leaks Any leaks must be repaired immediately. Nose and vibrations Stop the chain elevator immediately and identify the problem.
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. If the chain elevator is disassembled at the premises, start by removing the motor. For elevators with pulley drive, the pulley must be removed first, then the motor, the large pulley sheave and finally the guard. The easiest way to remove the chain is to dismantle the connector joint at the bottom of the elevator and then pull out the chain through the bottom inspection door. Screw off the motor stand and the elevator head. Finally remove all extensions. The chain elevator contains various materials that can be reused. All metal parts should be delivered to a recycle industry.
