TekoS-350mm

Extended and retracted

Functional description

The hydraulic buffer protects the rescue service against foot injuries.

In its the normal state the three-part telescopic apron is retracted. Therefore no touch-down or grinding noises occur when the car reaches or leaves the lowest landing.
The total height is only 350mm. If passengers have to be released, the apron is unlocked with a triangular key directly on the apron.
To avoid accidents when releasing passengers, the landing door has to be opened just for a few centimetres. Therefore every apron is equipped with three triangular locks for left, right or centrally closing doors. To extend the apron only one lock has to be used.

Intended use

Locking in extended state

The three-part telescopic apron prevents the inadvertent fall of persons into the lift shaft beneath the car.

In the extended state the telescopic apron locks itself. According to EN81-21 the apron can only be reset manually from the shaft pit.

Prevention of foot injuries

The triangular locks are connected by a rod on the backside. So if the apron is unlocked by the rescue service, the extension process is damped to avoid foot injuries.

Triangular locking device

Safety advice

The safety label has to be placed where it can be seen if the landing door is opened only a few centimetres.
Locks with internal return spring.

An adhesive label in the machine room and on the apron informs the rescue service about the retracted apron.

Switch supervision

Table: door width

A switch supervises the retracted state. The apron automatically locks into its normal position when pushing it upwards.

Advice: Cabin door locking

Advice: Collision prevention

The manufacturer categorically recommends an additional cabin door locking device, if the client does not provide for equivalent safety measures, in order to prevent the endangerment of locked in persons when they release themselves. E.g. in case of revolving doors due to the construction it is often not possible to release oneself even when there is no cabin door locking device.

When going down, a directional switch has to prevent that the lift can be moved with the control of inspection operation and the lift return control in the area, where an apron, which is not retracted, may collide with the pit floor.

Scope of delivery 2

Warning notices for landing doors, necessary for all landing doors.
Not necessary with cabin door locking device.

The manufacturer categorically recommends an additional cabin door locking device, if the client does not provide for equivalent safety measures, in order to prevent the endangerment of locked in persons when they release themselves.
According to the manufacturer’s prototype certificate this residual risk can be covered alternatively by affixing warning notices to every landing door, when a cabin door locking device is not possible due to technical reasons. The responsibility for the choice of the safety measure which guarantees sufficient safety in each case is incumbent on the user.

When planning, we recommend to consult the respective technical inspection agency.

Included in delivery:
• 1 pc. yellow adhesive label 80x120mm
• 1 pc. plastic sign
• 1 pc. tapping screw

The yellow adhesive label must be affixed completely to the door frame in the shaft, directly above the respective locking device.
As in many cases there is no smooth surface, a solid plastic sign is generally provided.

Safety labels foreign countries

If the apron is used in non-German speaking countries, the saftey label to be glued on apron have to be ordered seperately for the respective national language.
