    7.  
  7. Loading at serving height possible


Key components

Drive unit
comprising motor, gearbox, traction sheave (chain sprocket, rope drum) and failsafe brake
Motors
most service lifts use three-phase motors; lifts running at higher speed may also use direct current motors
Gearbox
Cylindrical, worm or planetary gear
Brake system
Drum brake, disk brake
Control system
mostly microprocessor controls 

Safety devices

Device for locking landing doors:
Safety devices which prevent a landing door from being opened if the lift car is not at that landing
     
  • Tower bolts
    •  
  • Hook bolts

Safety gear: 
Safety device to guard against free fall of the lift car; actuated by an overspeed governor
     
  1. Instantaneous safety gear
    2.  
  2. Progressive safety gear

Overspeed governor:
Tripping mechanism for safety gear (actuated by centrifugal force) 

Ascending car overspeed protection:
not required

Buffers
Devices limiting the travel of lift car and counterweight
     
  • Energy-accumulating shock absorbers
    •  
  • Energy-dissipating shock absorbers

Special features

Safety gear, overspeed governor and buffers are only required if the lift pit is accessible.
