Elevator Progressive Safety Gear Type With 0.63 M/S Or Less
Elevator
Safety Gear working principle is: by security clamp lever to drive
speed limiter, wire rope by tension wheel speed limiter wire rope
and the friction wheel speed limiter, makes the speed limiter wheel
speed consistent with the car to run faster.
When the running speed of the car (safety clamp, safety clamp
lever, speed limiter wire rope, speed limiter wheel) is greater
than or equal to 115% of the rated speed, the speed limiter acts,
and the brake rope block presses the speed limiter wire rope to
stop running, and drives the safety clamp lever to make the safety
clamp action.
Safety clamp is divided into the instantaneous type pliers and
progressive safety gear, instantaneous safety gear type with 0.63
m/s or less elevator, progressive safety gear used for 0.63 m/s of
the elevator
This SN-SG-LSG10 type safety clamp is a progressive safety Gear,
and its main parameters are shown below

FAQ
1. Are the elevator wire ropes durable?
The elevator wire rope has special provisions and requirements.
Configuration is not only for wire rope and rated load, but also
considered the size of the traction, as a result, the tensile
strength of wire rope is greater than the weight of the lift. The
safety factor is equipped with more than four wire rope. So it
won’t break at the same time.
2. Is it dangerous for power failure suddenly during the elevator
running?
If it occurs, the elevator will automatically stop due to the
electrical and mechanical safety device. In case of power
failure,elevator brakes will automatically taken. In addition, the
power supply departments such as planned outage, prior notice are
also operating.
3. Will us be hurt when it closed suddenly?
In the closing process, if people touch the hall door, the door of
elevator will automatically restart without any danger. With anti
clamping switch, once the gate touched, this switching action make
the elevator unable to be closed and even reopened. In addition,
closing force is also available here.
4. How the elevator running?
Elevators are operated with a counterweight wire rope through the
(tractor) traction drive, making ups and downs on the guide rail.
5. Is the escalator installation complicated?
We believe the functions of an escalator are not necessarily
proportional to the operation complexity. Therefore, escalators
designed by us apply an integrated structure, so that the equipment
is more precise and more efficient and allows easier and more
convenient commissioning.
6. Do you have any cerifications?
Yes, we do with ISO9001 / CCC / CE Certificates for u.
