PMH-H Series
Gantry Style Mold Handlers
General
PMH-H series mold
handlers/manipulators are designed for use on both
flask and flaskless molds. Designed as rugged and
highly effective devices, the PMH-H will provide
years of trouble free service.
Clamping
Clamping is
accomplished through the use of a large diameter
ball screw assembly. The assembly is designed for
40,000 plus hours of continuous usage (4.5 years
constant). Given normal usage of these units, this
will provide up to ten years of service without
replacement based on expected life.
The ball screw
assembly is totally enclosed in a heavy wall steel
housing protected by two seal sets ensuring no
penetration from dust particles.
Driven by a 2-HP,
480-Volt, 3-Phase motor through a high reduction
gearbox, the PMH-H clamping is consistent,
controllable, and does not suffer bleed-back as do
hydraulically clamped systems. This no-bleed-back
feature makes for a safer mold-handling environment,
instilling confidence in the workers who use
it.

Rolling
The PMH-H series is
designed to handle rated capacity off-center loaded
by approximately 10% (nearly double that of others).
This, coupled with high strength steel gripping
pads, ensures that you can roll even the toughest of
jobs with ease. Rolling power comes from a 1-HP,
480-Volt, 3-Phase drive coupled with a triple
reduction gearbox to deliver up to 80,000-inch lbs.
of torque (6,666-ft. lbs.) Single side powered
rolling reduces duplication of parts, which lowers
cost and maintenance concerns.
Leveling
The
PMH-H is leveled using a heavy-duty sprocket/chain
rack and pinion combination in conjunction with a
1-HP, 480-Volt, 3-Phase gearhead motor. Leveling can
be accomplished manually by the operator or
automatically using a mercury leveling switch.
The auto-leveling
feature ensures that the operator can clamp a mold
single-handedly. This also makes locating the
clamping jaws on the mold less critical.
Maintenance
The
PMH-H is powered completely using electrical drives.
This eliminates messy leaks, high maintenance, and
inconsistent delivery of hydraulic based systems. As
always, this piece of Palmer equipment is designed
to require a minimum of maintenance; yet, when
maintenance is required, it is easy to perform.
All spare parts are
off-the-shelf available either through the Palmer
Spare Parts department or from a high quality
industrial supplier.
