Zero-Max Overhung Load Adaptors (OHLA®) provide load support to eliminate
premature hydraulic motor failure. OHLA’s provide a solid mounting surface while
sealing out dirt and contamination in harsh environments.
Zero-Max OHLA’s provide support for both radial and axial loads. Applications
include fan mounting, forestry shredders, recycling systems, cold planers for road
paving, industrial conveyor drives, and many others.

microprocessor-based module includes digital display of volts, amps,
frequency, k W, phase to phase amps,
load programming, 16 point load profile capacity and Modbus. It is supplied with a 32. 8 ft. connection cable,
and a 20 ft. cable set with connectors
is available as an option.
“When you talk to the rental compa-
nies, they’re using 20, 30 or 40 load
banks at a time,” said Prevoznik. “So
instead of having one technician run-
ning around manually flipping switch-
es on 40 load banks which is very
hard to do, takes extra time and a lot
of extra money, this Sigma Controller,
allows one or two techs to control 22
load banks or more.”
Each LPH150S load bank also incor-
porates a control panel that provides
functions for on/off, start, stop and reset
push buttons, a status on test indica-
tor and station select rotary switch.
Safety circuits include load circuit fus-
ing, wrong voltage protection, air-fail
and over-temperature protection.
The unit’s resistive elements are
what Prevoznik called a “new hybrid
design that’s a mixture of Avtron
Helidyne elements and industrial
heating elements that provide a lot of
capacity in a small package.
“The technology of the fans has
also been improved,” Prevoznik said.
“We’re using low noise, high velocity
muffin fans that give us enough cool-
ing for 150 kW of power while main-
taining a small dimensional footprint.”
The load bank cooling system and
controls are powered through stan-
dard 120 V single phase power, with
a detachable power cord supplied
with the unit.
The resistive elements and fans
are housed within an aluminized steel
enclosure with screened openings for
inlet and exhaust air. Casters at each
corner allow for easy maneuvering,
the company said. The enclosure also
includes heavy-duty lifting handles.
Designs for 400V, 50 Hz, traditional
manual control or custom units are
The LPH150 load bank is 37. 48
in. high, 21.75 in. wide and 31.85
in. deep and weighs approximately
200 lb. The load banks have gone
into regular production at Avtron’s
Cleveland, Ohio, facility. dp
Avtron’s new LPH150S load bank incorporates the company’s Sigma 2 Intelligent
Handheld Terminal (IHT) controller to provide the control interface for all the functions
within as many as 11 individual load banks.
