2 Drum raes RT / E / S acc. to DIN RT-, E- and S-drum braes share the following features: Function of brae Type Spring actuated Lifting by thruster Torque adjustable rae closes with power failure by pre-stressed spring (Fail-Safe-Principle) Spring tube component and thruster are mounted to the nee lever. Special features Design according to DIN 15435, therefore guaranteed interchangeability Synchro-lifting-mechanism at type RT or adjusting bolts at type E and S as well as on brae shoes In connection with an automatic wear adjustment (AVN) the lifting gap remains constant across the entire abrasion range Enclosed spring tube eeps spring from damage and contamination rae torque adjustable, brae torque scale in Nm-segments for coefficient of friction µ = 0,3 and 0,4 Options and accessories (selection): Automatic wear adjustment (AVN) rae lining riveted and/or bonded Different brands of brae lining and different coefficient of friction are available Greaseable bearings Stainless steel pull rods Special construction for horizontal or suspended mounting with support Monitoring devises (limit switches) for: rae (open/closed), remaining lift, lining wear, temperature etc. Manual lifting rae types differ as follows: Single bar brae shoe lever, steel, narrow construction RT and E Twin bar brae shoe lever, steel, broad construction S Synchro-lifting-mechanism to simultaneously lift brae shoes, type RT Adjusting bolts to evenly lift brae shoes, types E und S (recommended if brae drum axis centerline does not match the centerline between base plate mounting holes)

34 Optional Equipment for Drum raes The following function and adjustment description inform about standard optional equipment: 1. Automatic wear adjustment to compensate lining wear in this case the necessary reserve stroe of the thruster is warranted. To automatically chec the lining wear, option 5. motoring lining wear is recommended. 2. Hand lifting lever for drum diameter 400 or smaller to open the brae during power failure or maintenance 3. Hand lifting lever for drum diameter 400 or larger to open the brae during power failure or maintenance 4. rae position control One limit switch each can be used to monitor the following brae positions: closed opened adjust brae (chec) remaining stroe is marginal 5. Monitoring lining wear y lining wear of approximately 50% the limit switch triggers a signal. The trigger position is adjustable. 6. rae retarder To slow down brae torque application during remaining last third of closing stroe. The adventage of a adjustable damping compared to a lowering valve is such, that the time delay is initiated shortly before brae drum and shoe contact and the dead time is not as noticeable as with valve. Further special design, prone brae position, left hand construction, different lifting technics as shown convers etc. on request

35 Drum raes Automatic Compensator Unit Adjusting the automatic compensator unit The adjustment explained below may only be executed when the brae drum is cold D Caution: The readjustment unit is used for compensation of lining wear. However its compensating capacity per breaing cycle is limited. Therefore an additional manual wear compensation carried out by maintenance personnel is required according to the specific application. The readjustment taes place without paying attention to the remaining brae lining thicness! 1. Close the brae: - Turn adjustment screw counter-clocwise in the brae lever until guide hole (4) is exposed. - Push driving pin (3) down in guide hole (4) as far as possible. 2. Lift brae lever several times fully and close again, driving pin (3) is now in correct position. 3. Turn adjustment screw (1) clocwise in brae lever down until there is a small gap of approximately 0,2 mm between adjustment screw and driving pin(3), tighten loc nut (2)

A linch pin secures the hand lever and spacer. The spacer should be permanently attached to the bolt. Remove the linch pin by pulling the spring tensioned ring up and pull the pin out. Slip the hole of the hand lever over the bolt, insert the linch pin in the bolt hole and secure it by pushing the ring down. y pulling up the hand-lever the bolt of the lever will catch the nee-lever pulling it up and thus opens the brae. Secure the hand-lever manually in position as long as the brae stays open. The design of the lever-arrangement is made to avoid an accidental opening of the brae. ATTENTION: After finishing the emergency or service procedure remove and eep the hand lever on a secure place before re-starting the brae

37 Drum raes rae Hand Lever above Size 400V nee lever in opened position nee lever in closed position hand lever in unoperated position spring tube hand lever The hand-lever is used to open the brae manually in case of an emergency or to service the unit. A swiveling device is permanent mounted to the spring tube. For the manual brae opening the hand lever is to be pushed into the matching hole of the swiveling device. y pulling up the hand-lever the roller of the lever will catch the nee-lever pulling it up and thus opens the brae. If the hand-lever is turned up to the limit stop the brae will be loced in that opened position! ATTENTION: After finishing the emergency or service procedure remove and eep the hand lever on a secure place before re-starting the brae

Electrical connection The group of limit switches is factory wired to the switch box (if not requested otherwise). The switch positions of the limit switches are factory adjusted and sealed with paint. To mae the electrical connection, disconnect the electrical current. Use authorized personnel only and obey local codes. Limit switch S4 and S6 will be connected to terminal 21/22 (brea contact) and to terminal 13/14 (mae contact). If limit switch S5 is in the closed position the brae shaft drive must be OFF and loced. 2. Adjustment of limit switch All roller levers are adjustable with a 10 angle catch. The levers are positioned correctly (factory set) if the axis is parallel to the limit switch axis, without being triggered by the trigger bloc. Each trigger bloc is custom-made for each brae size and stroe of thruster and not interchangeable with other blocs even when they are looing similar. The trip lever must move down, when limit switch S6 is used as an adjustment indicator. This should be granted by checing the all around thruster situation. The signal point of the switch can be changed by modifying the trigger bloc. 3. Maintenance The limit switches require no special maintenance. With rough conditions, we recommend routine maintenance as follows: chec actuators of limit switch, shafts and rollers, for easy operation remove all dirt, snow or ice etc. eep cams and roller shafts clean and lubricate slightly chec sealings of cables or conduit connections

Electrical connection angle position in pos. : "OFF" standard position: 2 clics out of center The limit switch is factory wired to the switch box (if not requested otherwise). The switch position of the limit switch is factory adjusted to the dimension as shown on the setch above, and sealed with paint. To mae the electrical connection, disconnect the electrical current. Use authorized personnel only and obey local codes. Connect the limit switch to terminal 21/22 (brea contact) and to terminal 13/14 (mae contact). 2. Adjustment of limit switch The roller lever is adjustable with a 10 angle catch. The lever is positioned correctly (factory set) at an angle of 20 to the limit switch axis without touching the trigger disc - as shown on the setch above. The switch signal point is factory adjusted so that, if the brae pad wears to a thicness about 5mm a signal will be given. To change the signal point the distance between roller and trigger disc is to be changed. Loosen the screw and move the trigger disc as necessary. Tighten the screw and chec for movement. Mae sure that there is sufficient brae pad left for the new setting of the signal point. 3. Maintenance The limit switch requires no special maintenance. With rough conditions, we recommend routine maintenance as follows: chec actuator of limit switch, shaft and roller, for easy operation remove all dirt, snow or ice etc. eep cam and roller shaft clean and lubricate slightly chec sealing of cable or conduit connection
