Section 2 – Safety Considerations and Precautions

Before installing and operating the MHCP Primary Cleaner, it is important to review and understand the following
safety information.

There are set-up, maintenance and operational activities involving both stationary and operating conveyors. Each
case has a safety protocol.

2.1 Stationary Conveyors

The following activities are performed on stationary conveyors:

• Installation • Blade replacement • Repairs

• Tension adjustments • Cleaning

DANGER

DANGER

WARNING

WARNING

WARNING

!

!

!

!

!

It is imperative that Lockout/Tagout (LOTO)
regulations, be followed before undertaking the
preceding activities. Failure to use LOTO exposes
workers to uncontrolled behavior of the belt cleaner
caused by movement of the conveyor belt. Severe injury
or death can result.

Before working:

• Lockout/Tagout the conveyor power source

• Disengage any takeups

• Clear the conveyor belt or clamp securely in place

Use Personal Protective Equipment (PPE):

• Safety eyewear

• Hardhats

• Safety footwear

Close quarters, springs and heavy components create
a worksite that compromises a worker’s eyes, feet
andskull.

PPE must be worn to control the foreseeable hazards
associated with conveyor belt cleaners. Serious injuries
can be avoided.

2.2 Operating Conveyors

There are two routine tasks that must be performed while the conveyor is running:

• Inspection of the cleaning performance

• Dynamic troubleshooting

Every belt cleaner is an in-running nip hazard. Never
touch or prod an operating cleaner. Cleaner hazards
cause instantaneous amputation and entrapment.

Never adjust anything on an operating cleaner.
Unforseeable belt projections and tears can catch on
cleaners and cause violent movements of the cleaner
structure. Flailing hardware can cause serious injury
ordeath.

Belt cleaners can become projectile hazards. Stay as far
from the cleaner as practical and use safety eyewear and
headgear. Missiles can inflict serious injury.

3.1 Checklist

Section 3 – Pre-Installation Checks and Options

• Check that the cleaner size is correct for the beltline width

• Check the belt cleaner carton and make sure all the parts are included

• Review the “Tools Needed” list on the top of the installation instructions

• Check the conveyor site:

- Will the cleaner be installed on a chute

- Are there obstructions that may require cleaner location adjustments
(see 3.2 – Cleaner Location Adjustments)

- Is the install on an open head pulley requiring mounting structure

(see 3.3 – Optional Installation Accessories)

3.2 Cleaner Location Adjustments

Section 3 – Pre-Installation Checks and Options

In certain applications it is necessary to modify the location of the primary cleaner pole due to permanent
obstacles that obstruct the desired location. Relocating the pole location can be done easily and does not hinder the
performance of the cleaner as long as the “C” dimension is maintained.

NOTE: In the following example we will be lowering the pole location in the “Y” direction, but the same method
could also be applied in the “X” direction.

Conveyor situation:

Pulley Diameter: 900mm

X = 450mm

Y = 359mm

C = 575mm

1. Determine the given location dimensions and define the change needed. After laying out the given X & Y
dimensions, determine the distance of the modification required for adequate clearance of the pole and tensioning
system. (In the example we decide to lower the pole 50mm to clear the support structure).

2. Write down known dimensions. We can now determine two of the three required dimension which will allow us
to find the third. We know we cannot alter the “C” dimension, so this will remain the same. Also we are required to
lower the unit in the “Y” dimension 50mm, so we add 50mm to the given “Y” dimension.

X = ? mm

Y =359+50=409mm

C = 575mm

3. Determine final dimension. On a flat vertical surface,
using a level, draw one horizontal line and one vertical
line creating a right triangle (Fig 3a). Measure down from
the intersection the determined “Y” dimension and mark
(Fig 3b). With the tape measure starting at the modified
“Y” mark, swing the tape across the “X” line and mark at
the “C” dimension where it crosses the “X” line (Fig 3c).
Measure from the intersection to the “C” intersection and
this will be your new “X” dimension (Fig. 3d).

X = 403mm

Y = 409mm

C = 575mm

Section 4 – Installation Instructions

Physically lock out and tag the conveyor at the power source

before you begin cleaner installation.

1. Find the X, Y & C specifications. Measure the pulley diameter
(including the belt and the lagging) (Fig. 1).

Pulley Diameter _____

mm; X=_____mm; Y=_____mm; C=_____mm.

(Adjustments can be made to the X & Y coordinates to move away

from obstacles as long as the C dimension remains constant.)

CAUTION: Components may be heavy. Use safety-approved lifting procedures.

5. Install the mounting bases.

Bolt the mounting bases to the
chute with the bolts provided
(Fig. 5).

6. Install the blade cartridge.

Place the blade cartridge onto
the centre pole. Adjust the
extender poles until the holes
align with the holes in

the centre pole and lock the cartridge into place with the two bolts,
washers and nuts (Fig. 6). NOTE: Be sure at least 150mm of the extender

pole extends out of the mounting base on each side for tensioner
installation. Adjust the extender poles in the centre pole if more or less
length is needed.

Section 4 – Installation Instructions

2. Lay out the dimensions on the chute wall. Measure out the X dimension
horizontally from the centre of the pulley shaft and mark. (NOTE: It may be
easier to put a level on top of the pulley shaft, draw a horizontal line and then
measure down half the diameter of the shaft and make a line from the front of
the shaft. Now subtract half the pulley shaft diameter from the X coordinate
and measure on the line and make a mark.) Then measure down vertically the
Y dimension and mark. This is the correct position for the centre of the cleaner
pole (Fig. 2). Lay out and mark the same dimensions on the other side.

3. Mark and cut the mounting base holes. Using the
mounting base template provided in the instruction packet,
position the large pole hole of the template on the chute with
the hole notches aligned with the layout lines. Trace the pole
hole and mounting holes (Fig. 3). Each base can be mounted
in any position 360° around the pole as long as the pole’s
centre point does not change. Cut the holes on both sides of
the chute.

4. Assemble the extender poles to the centre pole. Insert the
extender poles through the chute holes and into the centre
pole and make sure the locating bolt holes align with the
centre pole holes (holes are offset to the lower half). Position
the centre pole with the welded nuts and locking bolts on
one side facing down and on the adjoining side facing away
from the head pulley (Fig. 4). Leave the locking bolts loose.
