Thrustors turned by 90 can be mounted. In this case please ask for changed dimensions. M For thrustors acc. to DIN are different manufacturers of products available. Notes for following table: 1) The different operation factors such as sliding speed, surface pressure, thermal load, condition of the sliding surfaces, brake drum material and environmental conditions can influence the friction coefficient µ. They should thus be taken into consideration in addition to the guiding rules of DIN when dimensioning the brake. The data for braking torque are valid for dynamical braking at normal operating temperatures and sliding speeds up to 25 m/s or max. 60 m/s for sinter linings. The operating temperature for standard organic linings may not exceed 250 C and the thermal flow density should not be more than 400 W/cm². For sinter linings (optional) max 350 C and 800 W/cm² are recommended. The holding torque of statically closing brakes could be lower. 2) Without thrustor 3) Dimensions in mm, modifications reserved! 4) The design for brake discs B1 = 40 mm may also be used for discs with B1 = 42 mm Modifications reserved

8 PROTECT YOUR HOIST SYSTEM Reduction of maintenance costs and failures German specialist in brake + safety technology. Concerning hoists with safety brakes at the board disc of the rope drum significant loads in the hoist gearing may appear. As a result of different reaction times of service brakes on the motor shaft and safety brakes push-like gearing torques of 10 times the nominal torque can bet he effect. These push-like loads can be of negative influence on the bearing lifetime and consequently on the gearing lifetime. + + service brake drum-, disc or band brake TURBO Control system reduction of the reaction time of electro-hydraulically thrusters Safety brake Caliper type SCFH 4 Reaction times of service brakes and safety brakes at the board disc of the rope drum should be more or less equal. Using an electro-hydraulic thruster for the service brakes (brakes between motor and gearing) the application of the patented TURBO control system of RFT is recommended. This control system for electro-hydraulic thrusters allows dead times of about 150 ms. Reaction times to be realized by this are comparable to dead times for safety brakes at the board disc of the rope drum. As a result mentioned push-like top gearing torques cannot act in a range described above. The TURBO control system can be used in combination with any thruster. In addition the control system may be equipped with an uninterruptible power supply (USV) to realize equal reaction times in case of power off and an emergency load lowering.

9 Disc Brake Caliper SCFH Direct acting, hydraulic release. page 1 of 4 Operating Principle Spring applied braking force Hydraulic release Fail Safe (if power fails the brake applies) Arrangement Direct acting without linkages Fixed, not floating Notable Features High braking torque, direction of rotation independent Supplied ready assembled, with pre-tensioned braking springs Two identical halves, and can be mounted in any position Manual adjustment for brake wear. Air-gap adjustable in the range of 1 to 3 mm standard low wear sintered pads with µ = 0,4 Encapsulated hydraulic system. The hydraulic piston is fitted behind the spring-pack, away from the friction zone. As a result the hydraulic seals and fluid are not subjected to braking heat, and no cooling is required to achieve reliable long term sealing and operation. Modifications reserved

The service temperature of organic pads should not exceed 250 C, and sintered pads should not exceed 600 C.

11 Disc Brake Caliper SCFH Direct acting, hydraulic release. Determining the Brake Torque: page 3 of Nm Nm The effective brake torque of a complete brake caliper is calculated using the following formula TBr = µ Fan D1 The effective diameter D1 can be found using the formula below on this page. Alternatively, the effective braking torque can be taken from the displayed diagram. Combinations of multiple calipers are possible to get a wide range of contact force. Example: 4 x SCFH 3 => 960 kn contact force for s = 2 mm airgap 1 x SCFH-1-80 => 77 kn 1 x SCFH => 120 kn 2 x SCFH-1-80 => 154 kn 1 x SCFH => 240 kn 4 x SCFH-1-80 => 308 kn 2 x SCFH => 480 kn 2 x SCFH => 800 kn 4 x SCFH => 960 kn SCFH SCFH SCFH SCFH SCFH-1-80 SCFH-1-60 SCFH-1-50 SCFH-1-40 SCFH-1-30 SCFH Nm Nm Nm Nm Nm Nm Nm Nm Nm Nm Nm Nm Nm Nm Nm Nm Nm Special Design and combinations on request!
