1.1 General Introduction

Before installing and operating the H-Type®

Primary Cleaner with V-Tips, 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

Section 2 – Safety Considerations and Precautions

DANGER

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.

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

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

- Are there obstructions that may require cleaner location adjustments

3.1 Checklist

In certain applications it is necessary to modify the location of the precleaner 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 = 301mm

Y = 478mm

C = 565mm

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 = ?"

Y = 478 + 50 + 528mm

C = 565mm

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 = 201mm

Y = 528mm

C = 565mm

NOTE: Observing the cleaner when it is running and performing properly will help to detect problems or

when adjustments are needed later.

6.1 Pre-Op Checklist

Section 6 – Pre-Operation Checklist and Testing

Section 7 – Maintenance

Flexco belt cleaners are designed to operate with minimum maintenance. However, to maintain superior

performance some service is required. When the cleaner is installed a regular maintenance program should be set

up. This program will ensure that the cleaner operates at optimal efficiency and problems can be identified and

fixed before the cleaner stops working.

All safety procedures for inspection of equipment (stationary or operating) must be observed. The H-Type®

Primary Cleaner operates at the discharge end of the conveyor and is in direct contact with the moving belt. Only

visual observations can be made while the belt is running. Service tasks can be done only with the conveyor stopped

and by observing the correct lockout/tagout procedures.

7.1 New Installation Inspection

After the new cleaner has run for a few days a visual inspection should be made to ensure the cleaner is

performing properly. Make adjustments as needed.

7.2 Routine Visual Inspection (every 2-4 weeks)

A visual inspection of the cleaner and belt can determine:

   •Ifthespringlengthisthecorrectlengthforoptimaltensioning.

   •Ifthebeltlookscleanorifthereareareasthataredirty.

   •Ifasnubpulleyisused,acheckshouldbemadeformaterialbuilduponthepulley.

If any of the above conditions exist, a determination should be made on when the conveyor can be

stopped for cleaner maintenance.

7.3 Routine Physical Inspection (every 6-8 weeks)

When the conveyor is not in operation and properly locked and tagged out a physical inspection of the

cleaner to perform the following tasks:

•Cleanmaterialbuildupoffthecleanerbladeandpole.

•Closelyinspectthebladeforwearandanydamage.Replaceifneeded.

1. Remove the tension. Loosen the adjusting nuts on the mounting

bracket/J-bolt assembly to remove tension from the arm (Fig. 1). This

releases the tension of the blade on the belt.

2. Remove the worn tips. Remove the nuts on each tip and remove the

tips from the cushion (Fig. 2). Clean all fugitive material from the pole.

NOTE: If tips are hard to remove use a screwdriver or hammer to

loosen it and then remove.

Physically lock out and tag the conveyor at the power source

before you begin cleaner installation.

4. Reset the correct blade tension. Loosen the J bolt jam nut and

turn the tensioner adjusting nut until the coil is 125mm long.

Measure the length of the white line on the spring (Fig. 4).

Complete on both sides of cleaner, if required. NOTE: e given

spring length measurement is a starting point only. Actual length

for correct cleaner blade tensioning may vary by cleaner width.

Test run the cleaner. Run the conveyor for at least 15 minutes

and inspect the cleaning performance. Check the spring length

for proper tensioning. Make adjustments as necessary.

3. Install the new tips. Locate each tip onto each suspension arm,

then install the hardware to fasten the tip to the suspension

arm (Fig. 3).
