WHAT’S NEW FOR THE PASSENGER Mains improvements for

Improved from 50 lux to 100 lux at 1 m above floor level. Feel safer with better lighting.

Mains improvements for

On car roof or side panels: Assistance to entrapped passenger in car is easier and safer both for mechanics and passengers.

5 lux for 1 hour duration. In case of entrapment, passengers don’t stay in the dark. Reduces risk of fire inside the car. Non-contact light curtain mechanism. No more Photocell based mechanism. Reduces risk of passenger being struck while entering or exiting the car.

For glass shafts: Reduce risk of injury in case of shaft glass break and fall into the shaft. Reduce risk of injury & falling into shaft during an emergency rescue when the elevator is not at a landing operation. 7

Guide rail for instance. Better comfort and ride quality. Company Proprietary & Confidential

OTIS SOLUTION FOR COMPLIANCE Impacts of new standards on

Impacts of new standards on

.

2 examples: - Common button on inspection control station - Deterrent device

If the distance between the wall & the interior of the balustrade handrail is r, instead of a 700 mm balustrade for a distance lower than 500 mm.

.

. From September 1 st 2016, one year in advance.

OTIS’ major asset is the allowing to avoid the opening at top of shaft.8

SHAFT : GENERAL REQUIREMENT Height between floors The rule for no more than 11m between floors is unchanged, except for Fire Fighting lifts which must have not more than 7m between floors. Ventilation Due to different rules for ventilation found within the Building Regulations in each European country, it is not possible for the standard to give guidance on this. Therefore the ventilation of this building space should be treated as any other and becomes the responsibility of the building designer. However, the manufacturer should specify the heat output of the equipment to be dealt with.


SHAFT : GENERAL REQUIREMENT Where there are accessible spaces under the pit a safety gear must be provide on the counterweight. It is no longer permissible to use a “solid pier” as a means of protection.

Where the pit is more than 2.5m deep, the access to the pit must be by a door at pit floor level. It is not acceptable for an engineer to climb down a ladder more than 2.5m without some means of fall protection. This will have an enormous effect on the design of the building.


SHAFT : STRENGTH 

All glass used in the well must be laminated. The previous requirement was only where the glass was considered as accessible, but now it is anywhere in the well.



There are new requirements for strength of walls, doors and pit floor.

This should withstand loads from guides, equipment mounted on the guides and “push through” forces caused by building shrinkage . This will lead to now guide rail fixing calculations and new forces to the pit floor. Company Proprietary & Confidential

EN115 : ANGLE OF INCLINATION 5.2.2 ANGLE OF INCLINATION The angle of inclination  of the escalator shall not exceed 30° , but for rises not exceeding 6m and a nominal speed not exceeding 0.50mps the angle of inclination is permitted to be increased up to 35° (see  in the Figure 2 below) The angle of inclination of Moving walks shall not exceed 12°.


EN115 : SUPPORTING STRUCTURE Clause 5.2.5 : Supporting structure shall be designed to support dead weight of the escalator or moving walk plus rated load of 5000 N/m 2. It shall be calculated in accordance with EN 1993-1-1. Note : Load Carrying area = (nominal width z1 (see figure below) of the escalator or moving walk) x (distance / 1 between the support) (see figure 2). Based on the rated load, the maximum calculated or measured deflection shall not exceed 1/750 of the distance/ 1 between the supports.


EN115 : HANDLING CAPACITY H.1 Maximum capacity For traffic flow planning, the maximum number of persons that can be carried by an escalator or moving walk in 1 h is given in Table H.1:

27/100 Company Proprietary & Confidential

EN115 : CLEAR HEIGHT NEED A.2.1 Clear height of 2,30 m shall also be applied to the unrestricted area.


EN115 : USE OF BOLLARDS - SAFETY I.1 Use of shopping trolleys and baggage carts on escalators: The use of both shopping trolleys and baggage carts on escalators is unsafe and shall not be permitted. The principle reasons why the use of these products is considered to be unsafe are foreseeable misuse, overloading and width restriction.

To prevent the people from carrying the Wheel chair and trolleys on Escalators or Moving walks we can have bollards in front of the entrance side of these units as shown in the attached picture.
