Parker's unique Nichols™ 700 Series two-speed motor utilizes two separate power elements on a common shaft. An integral series/parallel valve shifts between high torque, low speed (parallel) operation and high speed, low torque (series) mode in a ratio of 2:1. The use of two power elements eliminates the inefficiencies of traditional, single power element designs. Maximum dynamic side load at key 2000 lb.
Features/Benefits:
• High efficiency, high flow two-speed motor
• Intermittent pressure to 3500 psi
• Torque to 7800 lb-in
• Dynamic side load up to 2000 lb. at the key
• Shaft 1.25 inch nominal
• Two separate power elements on a common shaft for a 2:1 speed ratio
• An integral series/parallel valve that shifts between high torque, low speed (parallel) operation and high speed, low torque (series) modes
• Delivers twice the torque and half the speed in the parallel mode
• Delivers twice the speed and half the torque in series mode
• A selector valve that can be open or closed center
• A selector valve that may be actuated by an external pilot or optional solenoid valve.
• An open center selector valve that can be shifted “on the fly” while the motor shaft is rotating under load
• A selector valve that is spring loaded to return to its pilot-pressure-off position
• A normal mode of operation that is field changeable and can be selected as series or parallel
• Pilot pressure requirement of 300 psi higher than motor case or outlet pressure and may be as high as typical hydraulic system operating pressure
• Designed and manufactured in Greeneville, TN USA
