  • the prime mover comprises a braking device 7 with a first brake lever 8 and a second brake lever 9, at each of which a brake shoe is arranged.
  • the brake levers 8.9 are hinged at the bottom of the bearing block 5 and above a rod 10 out.
  • the rod 10 is centered on a arranged with the bracket 5 connected holder 11.
  • to Operation of the brake shoes is ever brake lever 8,9 a Compression spring 12,13 provided.
  • To ventilate the brake shoes is each brake lever 8.9 provided a magnet which is opposite to the Compression spring works.
  • the magnets are on a frame 14th arranged, which is connected to the bearing block 5.
  • a contact protection 15 covers the ropes between the Traction sheave 3 and the guide roller 4 from. Another, not shown touch protection covers on the Rear of the engine 1, the ropes between the Traction sheave 3 and the machine console 6 from.
  • a fan 16 is provided for cooling the drive unit 1.
  • One Terminal box 17 serves as an interface for cables the power supply and as an interface for Control lines.
  • a manual drive 18 provided with the motor shaft 2.1 without tools is detachable.
  • a cover plate 19 of the bearing block 5 has an opening 20 through which the hand drive 18th with the motor shaft 2.1 can be coupled.
  • the manual drive 18 is drivable by means of a handwheel 18.1.
  • the elevator car is manually moved depending on the load Upward or down to the next Stop moved and the passengers evacuated.
  • Actuate the handwheel 18.1 and simultaneously ventilate the Brake shoes by means of a Bremslmodalhebels 21 is the Motor shaft 2.1 moves manually, with the elevator car is lowered or lifted.
  • the brake release lever 21 is made from a yoke 22 with a first claw 23 and one Lever rod 24 with a second claw 25, wherein the yoke 22 is articulated at a pivot point 26 of the rod 24.
  • Fig. 2 shows the manual drive 18 with handwheel 18.1 of the Drive machine side ago.
  • a slot 28 is arranged at the end of a hollow shaft 27 of the Handwheel 18.1 .
  • the Hollow shaft 27 is on an extension 29 a Screw axis 30 attachable, wherein a bolt 31 of the Extension 29 fits into the slot 28, causing the Rotary movement of the handwheel 18.1 on the worm shaft 30th is transmitted.
  • a arranged on a housing 32 pin 33 serves as a torque arm.
  • a hub 34 with groove 35 is pushed onto the motor shaft 2.1.
  • Handles 36 facilitate the attachment of the manual drive 18 to the Drive machine 1 and the removal of the manual drive 18th from the prime mover 1.
  • Fig. 3 shows details of the manual drive 18.
  • Die Worm shaft 30 drives a worm wheel 37 into which an extension 38 of the hub 34 is inserted.
  • the Extension 38 of the hub 34 and the worm shaft 30 are mounted on both sides in the housing 32.
  • a first shuttering 39 with the handles 36 and a second casing 40th close the housing 32.
  • the hub 34 passed through the opening 20 and on the shaft end of the Motor shaft 2.1 pushed.
  • the groove 35 of the hub 34 fits a wedge of the motor shaft, not shown, 2.1. through the groove / wedge connection, the rotational movement of the hub 34th transmitted to the motor shaft 2.1.
  • Worm shaft 30 and Worm wheel 37 form a transmission with drive-side Handwheel 18.1 and the output side serving as a clutch Hub 34.
  • Fig. 4 shows an interior view of the end cover 19, the the bearing block 5 concludes.
  • the end cover 19 is used as contact protection for the shaft end of the motor shaft 2.1 while allowing easy installation of the Hand drive 19.
