Introduction

General Martin®Electric Vibrators (M Series) are designed and manufactured to

ensure the best performance and reliability in severe-duty applications. The

vibrator motor has a recommended operational ambient temperature and

mounting surface temperature range of -22 to 104°F (-30 to 40°C). If

operating the motor in environments beyond these temperatures, call Martin

Engineering, as the vibrator may require rating reduction, more frequent

lubrication, or lubrication substitution.

The vibrators in this manual may be referred to by their model numbers or

part numbers. Table VI in the “Part Numbers” section provides model

numbers and part numbers together with frame size. The following letter

designations are used throughout this manual:

• MM (Martin®Vibrator bolt pattern).

• MC (Cougar®Vibrator bolt pattern)

• MI (Invicta Vibrator bolt pattern)

•MV(Vimarc

®Vibrator bolt pattern)

• MU (Uras®Vibrator bolt pattern)

•MB(Bosch

Safety All safety rules defined in the above documents and all owner/employer safety

rules must be strictly followed when working on the vibrator.

Materials required In addition to metric hand tools, the following materials are required to install

this equipment:

• Rigid beam or mounting plate.

•Martin

mounting hardware, and Martin®BBAC Safety Cable Kit.)

Introduction

Martin Engineering M3910-04/19 2Martin®Electric Vibrators

Storage Store vibrator in an ambient temperature not less than 41°F (5°C) with a

relative humidity not more than 60%. If the vibrator has been stored for 2 or

more years, remove bearings, wash them, and repack them with new grease

(see “Maintenance”).

Before Installing Vibrator

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/pallet 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 vibrator from shipping container/pallet.

3. If anything is missing contact Martin Engineering or a representative.

WARNING

Turn off and lockout / tagout / blockout / testout all energy

sources to conveyor/loading systems to mounting structure.

4. Before installing vibrator, turn off and lockout / tagout / blockout / testout

all energy sources to conveyor/loading systems to mounting structure

according to ANSI standards (see “References”).

WARNING

If equipment will be installed in an enclosed area, gas level or

dust content must be tested before using a cutting torch or

welding. Using a cutting torch or welding in an area with gas

or dust may cause an explosion.

5. If using a cutting torch or welding, test atmosphere for gas level or dust

content.

6. Mounting surface must be strong and flat, 0.01 in. (0.25 mm) across

vibrator feet. (This will minimize internal stress to vibrator casting when

tightening mount bolts. Welding in the area of the mounting surface could

affect its flatness.)

7. Make sure mounting surface is free of paint and debris and foot of

vibrator is clean.

Before Installation

Installing Vibrator

IMPORTANT

Read entire section before beginning work.

CAUTION

If installation instructions are not followed, structure and

vibrator can be damaged. Abusing or handling vibrator

carelessly will accelerate wear and shorten bearing life.

Mounting vibrator

onto structure

1. See Figure 1. Locate vibrator in lower 1/4 to 1/3 of structure slope length.

If second vibrator is required, mount 180° from first vibrator and halfway

up slope.

Figure 1. Locating Vibrator on Hoppers

CAUTION

Never weld structure with vibrator mounted and wired.

Welding may cause damage to motor windings and bearings.

IMPORTANT

The object of rotary vibration on bins, hoppers, and chutes is

to transmit vibration through the wall into the product

contained inside. If structure is not made rigid, vibrator may

draw high amperage and move material less efficiently.

Make sure structure is free of paint before mounting vibrator.

2. If using customer-supplied mounting plate to mount vibrator onto

structure, do the following:

a. Make sure plate is at least the size of vibrator base.

b. Locate plate so that vibrator can be positioned as shown in Figure 1.

c. Weld mounting plate onto structure.

3. If using MartinW-beam Mount (or equivalent) to mount vibrator onto

structure (see Figure 2), do the following:

Installation

Martin Engineering M3910-04/19 5Martin®Electric Vibrators

a. Make sure mount plate is positioned on channel so that vibrator shaft

is always 90° to the length of the channel.

b. Locate beam so that vibrator can be positioned as shown in Figure 1.

c. Extend beam at least 3/4 the length of sloped wall. Cut off end(s) of

beam if necessary to fit on structure.

d. Skip-weld beam in place: Weld 3 in. (76 mm), then skip 2 in. (51 mm).

Repeat for entire perimeter of beam. Do not weld last 1 in. (25 mm) of

either end of beam or any corner.

e. Install vibrator onto W-beam mount.

Figure 2. W-beam Mount

CAUTION

Never weld structure with vibrator mounted and wired.

Welding may cause damage to motor windings and bearings.

Use only new Grade 5 bolts and lock nuts to install vibrator.

Old fasteners can break and cause damage to vibrator or

structure.

Do not use split lock washers to install vibrator onto mount.

Damage to vibrator could result.

Tighten mounting bolts in sequence shown in Figure 3. If not

tightened in order, vibrator casting could be damaged.

4. Before installing vibrator onto mount, apply thread sealing compound to

all bolts.

5. Install vibrator onto mount with new lock nuts, compression washers, and

bolts according to Table I. Tighten bolts in order given in Figure 3 to avoid

damaging vibrator casting. (Contact fastener manufacturer for specific

information regarding bolt torque.)
