OPTIONAL ACCESSORIES FOR GREENCO CYLINDERS
AUTOMATIC TENSIONER (T)
By keeping constant tension on the cable, the automatic tensioner increases both seal and cable life. To insure that cables will be tensioned properly under any circumstances, we strongly recommend an Automatic Tensioner. The Automatic Tensioner eliminates manual adjustment except for initial installation. After adjusting Tensioner nut, the cables will remain tight and the unit will automatically compensate for cable stretch. Tensioner is mounted at position 4 on the head.
Does not increase cylinder length • No additional air supply needed.
REED SWITCH (R)
IMPORTANT NOTE: For END STROKE SENSING, Reed switch package will increase mounting dimensions by 1-5/8" on Cable-Trol ® Models 07 & 10 and by 2" on all other Cable-Trols and Model 15 Trac-Trol ®.
DESCRIPTION OF A REED SWITCH CYLINDER
DESCRIPTION Greenco’s Reed Switch Cylinder consists of a hermetically sealed glass capsule containing two cantilevered ferromagnetic blades. The blades come together and close the electrical circuit whenever the magnet, mounted on the piston, passes under the response area of the switch. An integral arc suppressing resistor-capacitor circuit protects blade contacts from voltage spikes, thereby extending cycle life. The lead wires are shielded to protect against sending or receiving induced currents as false signals. The shield may be “drained” using un-insulated third wire. An ohmmeter is recommended to test the switch function. DO NOT USE an incandescent light bulb as high in-rush may damage the switch. Be sure to connect the reed switch to the power source through a load. Direct connection of the switch may cause damage to the internal elements of the switch. To prevent electric shock, always shut off power supply before handling electric wire leads. The comprehensive design of the cylinder barrel thickness and mass of magnet, coupled with low profile switch provides sensitivity, dependability, repeatability and desired response time. PROXIMITY and GO® switches also available. Contact factory for additional information.

SHEAVE BRACKET ASSEMBLY
Special applications such as remote location or turning corners may require one or more additional sheave bracket assemblies. They are furnished complete, ready for mounting.
Dimensions in inches.
CABLE ATTACHMENTS FOR CABLE-TROL
Certain applications may require special accessories as indicated. Where standard trolleys will not carry load properly our optional cable end accessories are offered.
These can be ordered on new units or can be field installed since they utilize a “manual swage” and are available in Models 15 through 50.
STUD SOCKET ASSEMBLY
CLEVIS SOCKET ASSEMBLY
EYE SOCKET ASSEMBLY
"H” TROLLEY STYLE
THE “H” TROLLEY IS STANDARD ON MODEL 50.
THE “H” IS OPTIONAL ON MODELS 15, 20, 20P, 25, 25P, 32 AND 40
LINEAR BEARINGS FOR THE TRAC-TROL ® TROLLEY
The Trac-trol® trolley contains four independent linear bearings for maximum load bearing capabilities. Each standard bearing contains a set of continuously re-circulating precision steel balls for low friction and superior wear resistance. The load is actually being rolled freely along the two hardened steel guide rods. Optional stainless steel guide rods and self lubricating polymeric linear bearings are also available (consult factory.)
20C REPAIR KIT
The 20C repair kit consists of two cable subassemblies and all the seals for any one model of Cable-Trol ® or Trac-Trol ® cylinder. When ordering you must specify the complete model number and serial number of the unit the repair kit is to be used on.
