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.
