The Crusher Feed Basket is a weldment which sites over the feed opening, it directs material into the crusher feed opening and reduces spillage. The feed basket is made of ¼” mild steel with a 3/8” base plate. Windows with steel mesh inserts allow the operator to view the material level in the feed basket. The feed basket is typically removed for highway towing.
Feed Basket Overflow to Rear Discharge Conveyor RD
Overflow material is directed to the discharge conveyor.
Adjustable king pin support - Adjustable tubular supports reduce the amount of blocking required in the kingpin area during plant operation, which simplifies set up and tear down. The kingpin supports are lifted and pinned for towing to clear the semi-tractor.
Power hydraulic raise and lower - Six tube in tube style heavy duty run-on jacklegs, with 6" diameter x 18" stroke cylinders to lift the plant into the operating position. Each cylinder is independently controlled from a hydraulic valve for precise control and ease of leveling.
Electric Starters, Wiring and Controls - 6' x 6' x 20" electrical enclosure with structural support to set on grade during plant operation. The enclosure is connected to the plant with 15' electrical cable. The enclosure has a main inlet line surge arrestor, warning horn, lifting eyes and main circuit breaker with door interlocked disconnect linkage. All on-plant equipment is controlled by NEMA rated starters that are mounted in a separate remote control panel. Crusher motor is controlled by a digital solid state reduce voltage starter (soft-start). All push buttons, pilot lights and E-stop switches are heavy duty, 30mm, oil and dust tight devices, and includes an hour meter located inside the enclosure and a door mounted amp meter for crusher amperage.
