Accessibility Improvement of Existing Lift

48. Scope of NL EN 81-82
This European Standard provides rules on how to apply EN to existing lifts to improve their accessibility for persons including persons with disability.

50. Scope of NL EN 81-31 This European Standard covers:
accessible goods only lifts;
With rated speed not exceeding 1m/s
With rated load exceeding 300 kg; and
Not intended to move persons.

51. Types of Accessible Goods only Lifts
Type A, where the intended use is bound to the following two simultaneous conditions:
Maximum rated speed: 0,30 m/s;
Maximum travelling height: 12 m;
Type B, where one of the conditions mentioned above is not fulfilled.

52. Some important information
Automatic power operated doors shall not be used.
Type A could be platform and not necessary enclosed cabin

53. NL EN81-22
Inclined Lifts

54. NL EN81-22
Safety rules for the construction and installation of permanently installed new electric lifts,
with traction or positive drive, serving defined landings levels,
having a vehicle designed to convey passengers or passengers and loads, suspended by ropes or chains and travelling in a vertical plan along guide rails that are inclined at an angle of between 15° and 75° in relation to the horizontal.

55. NL EN 81-22 Limitation Due to State of Art
Inclination: a variation in inclination is permitted for the travel path;
travel path: confined within the vertical plane;
Maximum capacity of the car: 7500 kg (100 passengers);
maximum rated speed (v): 4 m/s.

56. EN81-22: Requirement
Same principle of part 20 with the differences due to inclination, such as:
Formula, for the clear distance needed in the headroom: 0.035V2 Sin∝
