The delivery service is responsible for damage occurring in transit. CHANG 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 H&Z VB Series electric vibrators from shipping container/pallet.
3. If anything is missing contact Martin Engineering or a representative.

Turn off and lock out/tag out all energy sources to conveyor/ loading systems to mounting structure.
4. Before installing H&Z VB Series electric vibrators , turn off and lock out/tag out all energy sources to conveyor/loading systems to mounting structure according to ANSIstandards (see “References”).

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.

Installing H&Z VB Series electric vibrators
IMPORTANT
Read entire section before beginning work. This manual provides instructions for installations onto steel bins and hoppers only. For other installations, call Martin Engineering or a representative.

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.

Never weld structure with vibrator mounted and wired.
Welding may cause damage to motor windings and bearings.
IMPORTANT
The object of H&Z VB Series electric vibrators 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
c. Weld mounting plate onto structure.
Installation

3. If using mounting plate and channel assembly to mount vibrator onto structure , do the following:
a. Locate channel so that vibrator can be positioned.
b. Extend channel at least 3/4 the length of sloped wall. Cut off end(s) of channel if necessary to fit on structure.
c. Skip-weld channel in place: Weld 3 in. (76 mm), then skip 2 in.
(51 mm). Repeat for entire perimeter of channel. Do not weld last 1 in.(25 mm) of either end of channel or any corner.
d. Install vibrator onto mounting plate.
Figure 2. Mounting Plate and Channel Assembly

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, H&Z VB Series electric vibrators 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.)
