Marland Clutch

Marland has been producing overrunning clutches since 1931. Primary Marland products are backstops, clutches and clutch couplings utilizing either the principle of cylindrical rollers on inclined cam planes for low speed applications or sprag technology for high speed requirements.

CEBMAG Backstops
Automatic freewheeling allows emergency torque through reverse direction. Unit acts as a releasable torque absorbing backstop clutch to gently release great loads, such as a cement kiln.

• Completely Enclosed
• Long Service Life
• Continuously Self Lubricated
• Two Brakes

HB Clutches
Automatic freewheel clutch mounted on hydrodynamic brake. Allows brake to work only when lowering loads from draw works cable reel.

• Uniform Load Distribution
• No Loose Parts
• No Backlash
• Long Service Life
• Superior Roller Design

CECON Clutches
CECON Clutches (CECON = Completely Enclosed for Continuous Operation)

Marland One-Way CECON Clutches are designed for applications where one or more of the following conditions exist:

• Shaft speeds exceed the permissible maximum for standard clutches, clutch couplings or backstops.
• Uninterrupted, continuous operation is required
• Operation under extremely wet, dusty, abrasive or other adverse atmospheric conditions; or on unprotected outdoor applications; or subject to high ambient temperature.
• Shaft axis is not horizontal, as on cement kiln drives.
• Lubrication maintenance must be provided on a no "down-time" basis.

Features and Benefits

Disconnect Feature:
Both CEUS and CEUHS CECONS are available with a disconnect feature that provides physical separation of the input and output shafts. This allows maintenance to be performed on the non-energized driver while the disconnect CECON is locked out in the disconnect position. This feature complies with OSHA requirements.

Other features include:

• View port which allows visual confirmation of disconnect/connect status
• Full-speed testing of isolated equipment prior to reconnection
• Direct replacement for existing CEUS and CEUHS units
• Operates in Adverse Atmospheres
• Reduced Downtime
• Long Service Life
• Minimum Maintenance
• High Speeds
• Continuous Operation
• Operates in Adverse Atmospheres
• Reduced Downtime
• Long Service Life

Applications

• Dual Drives
• Creep/Inching Drives
• Turning Gear Drives
• Energy Recovery Systems
• Emergency Drives Kilns
• High Speed Backstops
• Barring Mills
