P&H planetary transmissions are designed for the severe duty that is demanded for mining materials in harsh climates. These units provide longer periods between rebuild than parallel shaft or split power swing gearboxes. The P&H transmission is significantly larger and more robust than off-the-shelf planetary transmissions but is comparatively more compact than the parallel shaft swing gearboxes. Replacing parallel shaft swing gearboxes with planetary transmissions eliminates the need for swing timing. The replacement will also provide added deck space around the swing units for inspection and maintenance access.
