5.2.5.3.2 Below each landing dooi’ sill the wall of the well shall comply with the following requirements:
a) it shall form a vertical surface which is directly connected to the landing door sill, whose height is at least half the unlocking zone plus 50 mm and whose width is at least the clear opening of the car access plus 25 mm on both sides;
b) this surface shall be continuous and be composed of smooth and hard elements, such as metal sheets, and shall be capable of withstanding a force of 300 N applied at a right angle to the wall at any point, being evenly distributed over an area of 5 cm2 in round or square section, it shall resist:
1) without permanent deformation;
2) without elastic deformation greater than 15 mm;
C) any projections shall not exceed 5 mm. Projections exceeding 2 mm shall be chamfered at ieast 75° to the horizontal;
d) furthermore, it shall be either
1) connected to the lintel of the next door; or
2) extended downwards using a hard smooth chamfer whose angle to the horizontal plane shall be at least 60°. The projection to this chamfer on the horizontal plane shall not be less than 20 mm,
5.2.5.4 Protection of any spaces located below the well
If accessible spaces do exist below the well, the base of the pit shall be designed for an imposed load of at least 5000 N/rn’, and the counterweight or the balancing weight shall be equipped with safety gear.
5.2.5.5 Protection in the well
5.2.5.5.1 The travelling area of the counterweight or the balancing weight shall be guarded by means of a screen, which comply with the following:
a) If this screen is perforate. EN ISO 13857:2008, 4.2.4.1 shall be respected:
b) this screen shall extend from the lowest point of the counterweight resting on Its fully compressed buffer(s) or balancing weight In Its lowest position to a minimum height of 2.0 m from the pit floor.
C) In no case shall it be more than 0,30 m from the pit floor to the lowest part of the screen. For buffers travelling with the counterweight, see 5.8.1.1;
d) the width shall be at least equal to that of the counterweight or balancing weight;
e) if the gap between the counterweight)balancing weight guide rails and the well wall exceeds 0,30 m then this area shall also be guarded in accordance with b) and C);
f) the screen may have slot(s) with the minimum width necessary to permit free passage of compensation means or for the purpose of visual inspection;
g) the screen shall have sufficient rigidity to ensure that when a force of 300 N being evenly distributed over an area of 5 cm2 in round or square section is applied at right angles at any point of the screen, it shall not deflect to cause the counterweight or balancing weight to collide with it:
h) the car and its associated components shall be at a distance of at least 50 mm from the counterweight or balancing weight (if there is one) and its associated components.
5.2.5.5.2 Where the well contains several lifts there shall be a partition between the moving parts of different lifts.
If this partition is perforate, EN ISO 13857:2008. 4.2.4.1 shall be respected.
The partition shall have sufficient rigidity to ensure that when a force of 300 N being evenly distributed over an area of 5 cm2 in round or square section, is applied at right angles at any point of the partition, it shall not deflect to cause the moving parts to collide with it.
5.2.5.5.2.1 This partition shall extend from within 0,30 m from the pit floor to a height of 2,50 m above the floor of the lowest landing.
The width shall be sufficient as to prevent access from one pit to another.
Where the conditions of not giving access to a hazardous zone according to 5.2.3.3 d) are met then such a partition screen shall not be provided below the lowest point of travel of the car.BS/EN 81-20-2014 pdf download.
