Introduction
Introduction
General The Martin®HD QB1™ Cleaner combines effective removal of carryback
with a long-lasting, one-piece blade. To introduce product back into the
product flow, the Martin®HD QB1™ Cleaner is installed on the face of the
head pulley. On a dual-cleaner system, a Secondary Cleaner is installed
immediately following the Pre-Cleaner to remove stubborn material left on
the conveyor belt. If a Pre-Cleaner cannot be used because of space
limitations, Secondary Cleaners can be installed alone. Multiple Pre-Cleaners
and/or Secondary Cleaners may be required to clean the belt. If the material-
handling process or product could be affected by contamination from the use
of these belt cleaners, the user is responsible for taking the necessary steps to
prevent contamination. Consult Martin Engineering or a representative for
alternate belt cleaners or belt cleaner locations to use where contamination
may be an issue.
Installations
without chutework
These procedures were written for equipment that is being installed on
enclosed pulley chutework. If the pulley is not enclosed, the equipment should
be installed using the best available field resources and methods to ensure that
the critical dimensions are followed for proper installation.
Belt cleaner
inspection access
If the belt cleaner is installed on enclosed pulley chutework, at least one
Martin®Inspection Door should be installed. Martin®Inspection Doors are
available from Martin Engineering or a representative.
Belt cleaner blades Martin®HD QB1™ Cleaner Blades are available in five different materials
(see Table I for specifications). Only standard (orange) Martin®HD QB1™
Cleaner Blades are made of materials that meet Mine Safety and Health
Administration (MSHA) requirements under “Interim Fire and Toxicity
Criteria for Products Taken Into Underground Mines,” March 22, 1977
(MSHA acceptance number MSHA-IC-95/1, MSHA-IC-95/7).

Introduction

Martin Engineering M4101-01/19 4Martin®HD QB1™ Cleaner
Before Installing Belt Cleaner
IMPORTANT
The delivery service is responsible for damage occurring in
transit. Martin Engineering CANNOT enter claims for
damages. Contact your transportation agent for more
information.
1. Inspect shipping container for damage. Report damage to delivery service
immediately and fill out delivery service’s claim form. Keep any damaged
goods subject to examination.
2. Remove belt cleaner assembly from shipping container.
3. If anything is missing contact Martin Engineering or a representative.
DANGER
!
Before installing, servicing, or adjusting the belt cleaner, turn
off and lockout / tagout / blockout / testout all energy sources
to the conveyor and conveyor accessories according to ANSI
standards. Failure to do so could result in serious injury or
death.
4. Turn off and lockout / tagout / blockout / testout energy source according
to ANSI standards (see “References”).
DANGER
!
If this equipment will be installed in an enclosed area, test the
gas level or dust content before using a cutting torch or
welding. Using a torch or welding in an area with gas or dust
may cause an explosion resulting in serious injury or death.
Follow local confined space procedures.
5. If using a cutting torch or welding, test atmosphere for gas level or dust
content. Cover conveyor belt with fire retardant cover.
IMPORTANT
Center the belt cleaner blades to clean an area narrower than
the conveyor belt width. This allows for side-to-side movement
of the belt and prevents damage to the belt edge.
NOTE
The chute wall that the tensioner will be located on is referred
to as the “operator side.” The other side of the chute is
referred to as the “far side.” (If installing dual tensioners, side
that is most accessible is “operator side.”)

Figure 2. Chute Width Requirements
IMPORTANT
Inside chute width must be a minimum of belt width plus
5 inches to insure there is adequate space to install cleaner and
tensioner. If chute width is too narrow either the tensioner will
need to be spaced off of the chute wall or the mainframe can
be cut down. The mainframe can only be cut down if the blade
is belt width minus 6 or 8 inches.
6. Inspect belt cleaner mounting area for possible obstructions that could
interfere with proper mounting. Refer to following guidelines:
a. The cleaner can be mounted anywhere on the arc from +30 degrees to
-30 degrees from a center line parallel to the belt line as long as:
(1) The blade is not in the direct flow of discharging material causing
premature blade wear.
(2) The diameter of the pulley is big enough that the blade does not
trap or hold material between the inside of the blade and the belt.
(3) There is at least the equivalent of a 45 degree angle between the
blade and belt to prevent material buildup in this space.
b. Lack of service is the main cause of poor belt cleaning performance.
Follow CEMA guidelines for access:
(1) Clearance for service outside the chute must be at least equal to the
belt width.
(2) Cleaners must have service platforms. CEMA recommends
cleaners be mounted at least 24 in. (600 mm) above the work
platform.
(3) If the belt width is 54 in. (1400 mm) or larger consider access
doors on both sides of the chute.
c. Refer to “Installing Belt Cleaner and Tensioner” and “Part Numbers”
sections of this manual for specific mounting and cleaner dimensions.
