 fishplate
5.2 Function of the safety gear
Upon tripping the overspeed governor both levers  synchronised by the actuating shaft are turned
by 15°.
In doing so the safety gear roller  moved by the lever makes contact with the rail surface.
The safety gear roller is pressed into the wedge-shaped gap between rail and roller guide . Owing
to the wedge effect of the roller guide the full floating beared safety gear is moved until the brake
shoe  rests against the rail .
The disc spring transmits the braking force to the internal housing. To adapt to different widths of
guide blades distance plates of various thickness  are placed under the disc.
The spring pressure is preset and secured by a safety plate  and a led-sealing to prevent
unauthorized adjustment.
In the braking process the brake shoe fixed on the bracket cuts into the rail surface. The braking
effect is caused by metal cutting in the rail surface, friction and spring tensioning work.
Moving the lift car upwards releases the brakes and lever and the safety gear rollers return to neutral
position.
The safety gear is ready for action again.
IMPORTANT
The safety gear transmits the braking force to the car. This braking force must be taken into account
in the construction of the interface between safety gear and car.

6. Assembly
6.1 Assembly of the safety gear at the lift car
The safety gear is fixed to the lift car with four screws of type M12 and bushes.
Pay attention to the full floating bearing the safety gear as this is the key to the safety gear sliding
into braking position after being tripped by the overspeed governor.
WARNING
When the safety gear is in neutral position it can be adjusted using the adjustment mechanism.
The following points must be observed:
The rail running guide must cover the brake shoes completely. The air gap between the rail running
surface and the brake shoe must be adjusted to 2 mm.
The safety gear must be installed so that the spring mounted brake shoe is parallel to the rail and in
direction of travel.

WARNING
Ensure that the mounting screws in the long slots of the external housing have enough play in both
directions in neutral positions.
Correct position of the safety gear
During assembly the safety gear on the car take care for the correct position of the safety gear.
Firstly there is an advice on the type plate of the safety gear, secondly the following characteristics of
the safety gear roller is only given if the safety gear is mounted correctly:
By pulling the lever upwards the gap between safety gear roller and rail gets smaller until the safety
gear roller rests against the rail.
WARNING
Incorrect installation of the braking device causes a functional disorder of the safety gear.
Linkage of the braking units
Both safety gear units are linked with an actuating shaft.
The actuating shaft is fixed to the lever of the safety gear with attachment screws or spring type
straight pins. The actuating shaft is connected by mean of two square-type tubes  20x20 mm.

Progressive safety gear SG Manual
SG braking downwards  Commissioning
www.slc
-liftco.com Doc. 300.000.123 I Version 02.2019 Page 13
7. Commissioning
7.1 Functional check
WARNING
Before commissioning the safety gear
make sure that the overspeed governor works correctly, that the safety gear is attached to the
overspeed governor and that the produced tractive force is two times the force required for
engaging the safety gear.
the guide rail must be cleaned of dirt. Most suitable for cleaning is cold solvent.
Before commissioning the lift car
the lift car must be braked statically:
by turning the actuating shaft until both safety gear rollers contact the guide rail as well as letting
the car down slowly. It has to be checked if both safety gear rollers move to their working
position.
the lift car must be braked with low speed.
It has to be checked if both safety gear rollers move to their working position.
For checking the braking force it is possible to trip the safety gear with rated speed or overspeed.
By pulling out from braking position the lever of the safety gear roller turns back into neutral position.
WARNING
The safety gear may be operated only in combination with an overspeed governor.
7.2 Commissioning at the lift
Braking the car in down direction with 125% of payload decelerations of the car must be between
0,2g and 1g (9,81m/s2).
7.3 Acceptance test or commissioning of the lift
IMPORTANT
Engagement test downwards
Tests before commissioning the lift according to EN81-20:2014-11, chapter 6.3
(EN81-1/2:1998+A3:2009, Annexe D) resp. periodic tests according to EN81-20:2014-11, Annexe C
(EN81-1/2:1998+A3:2009, Annexe E).
7.4 Check after braking
After every braking the safety gear has to be rechecked by a qualified person.
There is to be checked visually whether any changes or dirtying at the braking elements has
occurred.
The following points have to be rechecked:
excessive wear of the brake shoes
deformations
smooth running
The rubbed-off particles have to be removed and the braking marks grinded down.
Braking again on a re-grinded braking track is not causing an essential change of the braking force.
DANGER
For guide rail lubrication oil products approved in the type examination certificate shall be used only.
Use machine oil of viscosity class ISO 68-150 without extreme pressure additive. See mineral oils
without additive (for example lubricant C according to DIN 51517, Part 1.)
Oils for hydraulic aggregates, gears and motors are not suitable for this use.
