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 135 diameter augers have an inclination of

incl.60, incl.90, incl.125, available in lengths of 2.0m, 1.25m, 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, 1.25m, 1.0m and 0.5m.

A third combination is possible by using a 55° bend, which makes it possible to change from vertical position to 55°, e.g.

above a silo roof.

The chain elevator consists of:

• Elevatorhead

• Elevatorboot

• 2.5mextensionswithinspectiondoor

• Chainwithrubberslats

• Extensionsfrom0.125mto2.5m.

• Outlet

• Motor

Additional inlet piece is available.
