Machine Screw comDRIVEs
About Machine Screw ComDRIVEs
Joyce Machine Screw ComDRIVEs combine a machine screw jack, motor and gear reducer into a single compact unit. Motorized ComDRIVEs are available in 2-ton through 30-ton capacities with travel speeds up to 35.1 inches per minute. ComDRIVEs with single lead screws (CD) are self-locking; those with double lead screws (DCD) may require a brake to hold position.
- ComDRIVEs can power an entire jacking system
- Reduce the number of components that must be specified
- Simplify designs
- Reduce installation costs with only a single plate needed to mount the jack body
- Reduce the number of couplings and shafts required in multi-jack systems
- Standard 230/460 volt, 3-phase, 60 hertz motor included
- Custom finishes available
Parts list and exploded views are included in the O&M Manual. A serial number is attached to the product housing.
Jack Material Notes:
- Ductile iron jack housing
- Lifting screw, cold drawn steel (CDS)
- Input shaft (worm), CDS
- Aluminum bronze traveling nut (KFTN)
- 230/460 Volt, 3 phase, 60-hertz motor is standard

Important Note: *Not self-locking, may lower under load. Brake motors or external locking systems are recommended.
DCD: Double lead screw.
(For 25:1 ratio, contact Joyce/Dayton.)
K=Keyed for Non Rotation
* Standard trunnion mounts available on 2-ton through 20-ton jacks.
Rise is travel expressed in inches and not the actual screw length. When companion jacks are ordered with the ComDRIVE®, their screws are lengthened to match the ComDRIVE®.

Motor for Systems and Direct Drives
- All standard motors are 3-phase, 208-230/460 VAC or 230/460 VAC. Other motor options are available. Specify the appropriate motor size from the chart on the right.
- Refer to the "Additional Options" chart on the preceding page as needed.
- Brake motors (M2) are recommended for jacks that are not self-locking, and jacks with double lead screws.
- If the motor frequency will be varied to provide a "soft" start an inverter duty motor may be required.
