plus years of experience in swarf handling and swarf crushing. All these abilities have been used
to design a product with high reliability and long service life. We are convinced that your expe-
riences will confirm your choice of ARBOGA-DARENTH Swarf Conveyors.
Length of life and reliability can, as with any machine tool, be prolonged with correct installation
and correct maintenance. It pays off to follow our advice for maintenance.
This maintenance manual consists of instructions and spare parts list for your new ARBOGA-
DARENTH Hinged Steel Belt Conveyor. It also contains greasing instructions, spare parts list
and a simple schedule for trouble-shooting.
ARBOGA-DARENTH Swarf Conveyors are normally used in all machine tools on the market
as well as in swarf handling systems which ARBOGA-DARENTH designs, sells and installs.
All Conveyors which leave our works are checked and do not need any additional maintenance

Safety regulations
•Electrical installations have to be done by qualified personnel only.
•At connection of voltage feed as well as at service and maintenance work on the conveyor
the circuit breaker must be off.
•Test the emergency stop at installation and always when maintenance and service have been
done.
•The conveyor must not be operated with the covers removed.
•The data sheet from the coolant supplier must be studied as parts from coolant can cause
allergic reactions.
WARNING!
The floor around the conveyor might get slippery from coolant getting outside the machine.

Operation
ARBOGA Hinged Steel Belt Conveyors are designed to handle a variation of material in
different shapes and forms. They can convey short, long or curley swarf, dry as well as wet.
They can also convey parts. Ask ARBOGA-DARENTH!
The conveyor consists of the following main components:
Conveyor frame
Precision hinged steel belt
Drive system
Accessories (standard or customized)
The frame is designed to cover the chain wheels and its components for increased reliability. The
material is conveyed on the upper side of the belt, with a minimum of power, to your scrap bin.
To get a clean area around the conveyor it is equipped with a top plate. Optional the frame can
be welded waterproof.
Flights or cleats can be welded at regular intervals onto the belt in order to increase the capacity
of the conveyor. The belt is endless driven by a gear motor placed directly onto the shaft.
Examples of installations where the ARBOGA hinged belt conveyors are in sucessful use:
Incorporated into machine tools to convey swarf from the machine into a scrap bin (as well as
for conveying parts).
In channels below floor level connecting several or a line of machines for automatic swarf
removal.
In press lines to remove press scrap from the machine area.
I swarf handling systems
Installation
Shorter conveyors will be delivered completely assembled, ready to install and to use. Longer
conveyors will be delivered in sections.
The conveyor or the conveying pieces can be handled by a crane.
When frame junctions are used assure that the wheel path (the frame) is in level on both sides.
The belt side wings must overlap so that the rear part of the front side wing is conducted inside
the front part of the rear side wing.
The conveyors shall be placed on a plane ground. They need not to be fastened, but it is an ad-
vantage to securely fasten the conveyors with expansion bolts, if it is possible. No dynamic
forces are being transmitted from the conveyor.
The lubrication directions from the gear manufacturer have to be followed (see enclosure).

6
Maintenance instruction
After approx. 3 months operation in one shift, the conveyor shall be checked.
The following items shall be special attended.
1) Belt tension.
2) The chain and its position in the frame.
3) The rollers.
It can be necessary to retighten the belt. The frame and the chain should be checked for eventual
excessive wear. The rollers should be easy to move and should run freely. If necessary, the
rollers should be greased.
The belt must be in the middle of the frame to avoid unnecessary wear. When tightening the belt,
check that it will come in the middle of the frame, otherwise the shaft will not be in a straight
angle to the conveying direction. The belt must then be tightened (untightened) with the
tightening device, so that the belt will come into its correct position.
The conveyor must be checked in intervals. Damaged parts must immediately be replaced,
otherwise the function of the conveyor will be disturbed and even other parts can be damaged,
e.g. the belt and the frame.
Belt tightening
Proceed as follows by tightening the belt:
1. Loosen the screws (16) on the bearing plate (8) and the motor plate (5).
2. Tighten or untighten with the tightening screws (17).
3. Tighten the belt so much that it is possible to press it down about 5-10 mm just before the tail
end.
4. If it is not enough to tighten the belt with the tightening device, it is necessary to take away 2
hinges (see belt disassembly).
5. After the tightening of the belt, the screws mentioned in item 1 above shall be fastened.
NB! We recommend to take extra care in checking the belting and to follow the procedure above
when tightening. If the belt is tightened too hard or too loose, both conditions can cause
problems in operation and damage the belt and the conveyor itself.

7
Belt disassembly
Disassembly of the hinged belt can be done for two reasons:
•To replace damaged parts.
•Cleaning and maintenance of the conveyor trough.
Hinged belt
The belt is to be disassembled in the following order:
1. Loosen the screws (16) on the bearing plate (8) and the motor plate (5).
2. Untighten the belt by loosening the tightening screws (17). The screws to be totally un-
tightened.
3. Remove the motor (4 screws).
4. Remove the bearing plate and the motor plate.
5. Locate the drive shaft (10) so that the belt shaft (34) will be positioned in the middle of he
slot of the frame.
6. Remove the screw (35) from the belt shaft.
7. Pull out the belt shaft through the slot in the frame.
8. Unlink the chain links (33) and the side wings (30, 31), separate the belt and pull it out of the
frame. NB! We recommend to secure the belt so that it is not rolling back into the frame.
9. If you wish to exchange one belt plate, just exchange the damaged one.
10. Assembly takes place in the reverse order.
When you change the complete belt, please note that the side wings on the plate come in the
correct position. The wings must overlap in the conveying direction, i.e. to avoid jamming and
destruction of the wings. It is recommendable to note the position of the wings on the old belt for
correct mounting of the new belt. You can also find the correct position in the drawing in this
manual.
It is possible to pull out and mount the belt with the motor.
When disassembling the belt as per above, run the motor forwards.
When mounting a new belt, put it over the drive shaft and run the motor in reverse.
Cleaning and maintenance of this conveyor shall be conducted due to existing conditions.

8
Lubrication
Gear
The gear manufacturer's specifications are to be followed (see enclosure).
NB! Some gears are delivered without oil. It is in these cases fully marked on the gear.
The manufacturer's specification is valid.
Drive
The drive shaft bearings are to be greased every 6th month.
Pulley wheel shaft bearing
When pulley wheel shaft bearings are used the shaft bearings are to be greased every 6th month.
It is to recommend to grease the bearings additionally, when the conveyor is placed outdoors.
Bearing grease of good quality is to be used.
Trouble-shooting
Problem
Cause
Measures
The belt runs irregular.
The belt not tightened.
Tighten the belt.
Excessive wear on frame.
The belt uneven.
Adjust the tightening screws.
The belt jammed.
The belt not tightened or
scrap pieces block the con-
veyor.
Tighten the belt. If any for-
eign parts can have entered
into the conveyor, it is neces-
sary to disassemble the con-
veyor for inspection of belt
and frame.
The belt ”squeaks”.
The belt too tight.
Release tension by adjusting
the tightening screws.
