D440 Two-Speed Anchor Drive
Drive Head – Anchor Drive, Rated Output Torque 35,000 Ft. LBS. ( Nm), Maximum System Pressure 5,000 PSI, 4″ Square Hex Output Shaft.
The D440 Series Drive Head utilizes a heavy-duty three-stage planetary gearbox and a Load-N-Lock shaft retention system for extreme duty situations. Proper bearing pre-load and shaft retention strength are vital in most applications, especially in pinion/bull gear applications. The Load-N-Lock system covers both of these needs. The drive head uses highly-efficient variable displacement piston motors for maximum speed and torque.
