Description
EP700 Planetary Slewing Drives
EP700 slewing drives combine planetary reduction with a flange-mounted slew support and output options intended for rotating structures. Typical duties include excavator upper structures, cranes, wind-energy yaw systems, turntables, and other machines that need controlled low-speed rotation under high overturning and shock loads.
Published Family Data
The official series summary lists an overall output-torque range of approximately 1,000–80,000 N·m and ratios from about 3.3 to 3,000 depending on construction. The representative table below uses the published excavator/crane model values.
| Type | Max Torque N·m Excavator / Crane | Ratio Range | Max Input rpm |
|---|---|---|---|
| EP700L1A | 1,000 / 1,200 | 3.38–7.2 | 2,000 |
| EP701L1A | 1,800 / 2,400 | 3.38–7.2 | 2,000 |
| EP703L2A | 2,500 / 3,500 | 12–44 | 3,000 |
| EP705L2A/B | 5,000 / 6,500 | 12–44 | 3,000 |
| EP706L2B | 7,500 / 10,000 | 13–44 | 3,000 |
| EP707L2B | 9,000 / 15,000 | 13–43 | 3,000 |
| EP709L2B | 12,000 / 20,000 | 14–47 | 3,000 |
| EP710L2B | 18,000 / 30,000 | 14–45 | 2,500 |
| EP711L2B | 20,000 / 35,000 | 14–45 | 2,000 |
| EP713L3B | 40,000 / 55,000 | 50–300 | 2,000 |
| EP715L3B | 70,000 / 80,000 | 52–320 | 2,000 |
Output Options
Published output arrangements include splined shafts or an integral pinion, supported by heavy-duty bearings. Electric AC/DC brake options and hydraulic motor valve or parking-brake options can be configured around the application.
Slew-Duty Checks
| Variable | Selection Question |
|---|---|
| Rotating inertia | What mass and radius must be accelerated and stopped? |
| External gear | What pinion module, tooth count, and center distance are required? |
| Holding duty | Is a service or parking brake required? |
| Wind or slope load | What external resisting torque acts on the structure? |
| Cycle profile | How often does the drive start, reverse, index, or hold? |
| Mounting | What flange, pilot, shaft, and bearing loads must be carried? |
FAQ
Can EP700 use electric motors?
The published family supports IEC electric motors as well as hydraulic motor options, subject to the selected construction.
Is an integral pinion available?
Yes, the public series description lists splined output or an integral pinion as output choices.
Why is holding torque important?
Slew systems may see wind, slope, inertia, or suspended-load effects while stopped. Brake and static torque requirements should be defined separately from running torque.
Can I replace an existing slew drive by model name only?
A model cross-reference helps, but the pinion, flange, center distance, mounting, brake, motor, and load data still need confirmation.
Data Note: EP700 torque, ratio, model, brake, motor, and output information is sourced from the official Ever-Power slew-drive product page. Values are family data, not a blanket rating for every configuration.
