Conditions of use
JEMA AGRO A/S chain elevators T20/T40 have been constructed for transport of grain, granular materials and
seed mix.
• The chain elevators T20/T40 must only be used for the product(s) specified in the contract.
• The electrical connections must be done by a qualified electrician.
• The chain elevators T20/T40 must be potential adjusted in accordance with the current local regulations
• The chain elevators have been thoroughly controlled regarding maintenance, and a checklist has been drawn up
containing regular cleaning- and maintenance intervals. If these intervals are not observed, the JEMA AGRO
conditions for a trouble-free operation cease to exist and the warranty will be invalid.
• During installation, maintenance or repair the electric supply to the chain elevators must be disconnected
and secured against accidental reconnection.
• The user manual must be kept / be available in close proximity to the chain elevator T20/T40

Delivery
The chain elevator is disassembled for shipment. Standard packing (pallet/wooden boxes,
grid boxes, etc.) Regarding the actual transport there are no specific requirements apart
from normal consideration.
The shipment includes the parts stated in the order confirmation.
Please read this manual carefully before installation and use.
Storage
There are no precautions regarding long-time storage.
After delivery the components must be kept in a suitable, dry storage area before
installation.
Noise level
A noise level test was conducted for the chain elevator. The level has been measured in a
distance of 1 m from the conveyor surface and at a height of 1.6 m from the floor level.
During the test the chain elevator was running unloaded, which is the operational state of
maximum noise level.
The measured noise level is not higher than 70 dB

Type Plate
The type plated is fitted on the drive station.
Construction
The chain elevator type T20/T40 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.
The side auger in trough is available for both left and right elevator. The augers are Ø135 or Ø180.
135 diameter augers have an inclination of S60, S90, S125, available in lengths of 2.0m, 1.25m, 1.0m, and 0.5m.
180 diameter augers have an inclination of S160 available in lengths of 2.0m, 1.0m, and 0.5m
Another combination of vertical and horizontal transport can be obtained by using a 90° bend. The inlet trough is fitted
horizontally and attached with a 90° bend to the vertical part of the elevator. The inlet troughs are available in lengths of
2.0m, 1.0m and 0.5m.
The chain elevator consists of:
• Elevator head
• Elevator boot
• 2.5m extensions with inspection door
• Extensions from 0.125m to 2.5m
• Chain with rubber slats
• Motor
• Possibly side augers
• Possibly inlet for extensions (retun side)
