Dear Sirs,
The question you should be asking is who is doing the maintenance and how often is this equipment checked? Are the maintenance personnel trainned?
Are there records of this being done?
How is the Kinetic energy of the doors measured? (By guess and by golly?)
There is more to the subject than you may realize contact me and maybe we can open a discussion.
I have developed a kinetic energy calculator the measures the speed of the closing doors and calculates the mass of the doors from the impulse of the doors to derive kinteic energy. These formula were put forth by Sir Issac Newton. So, again I ask, how often is this checked, and by whom? If some one holds a spring that looks like a fish scale on the door and purports that this is how the kinetic energy (energy that hits granny when the door slams on her) they are not only fooling you but themselves as well.
The amount of kinetic energy is a code related issue in ASME A17.1
This is enforcable in states that adopt it and also enforcable as an OSHA issue in Section 5 A 1. The general duty clause.
Below is what is stated in this code.
2.13.4.2.1 Kinetic Energy
(a) Where the hoistway door and the car door/gate are closed in such a manner that stopping either one manually will stop both, the kinetic energy of the closing door system shall be based upon the sum of the hoistway and the car door weights, as well as all parts rigidly connected thereto, including the rotational inertia effects of the door operator and the connecting transmission to the door panels.
(b) Where a reopening device conforming to 2.13.5 is used, the closing door system shall conform to the following requirements:
(1) The kinetic energy computed for the actual closing speed at any point in the Code zone distance defined by 2.13.4.2.2 shall not exceed 23 J (17 ft-lbf).
(2) The kinetic energy computed for the average closing speed as determined in accordance with 2.13.4.2.2 shall not exceed 10 J (7.37 ft-lbf).
(c) Where a reopening device is not used, or has been rendered inoperative (see 2.13.5), the closing door system shall conform to the following requirements:
(1) The kinetic energy computed for the actual closing speed at any point in the Code zone distance defined by 2.13.4.2.2 shall not exceed 8 J (6 ft-lbf).
(2) The kinetic energy computed for the average closing speed within the Code zone distance (see 2.13.4.2.2), or in any exposed opening width, including the last increment of door travel, shall not exceed 3.5 J (2.5 ft-lbf).
2.13.4.2.2 Door Travel in the Code Zone Distance
(a) For all side sliding doors using single or multiple speed panels, the Code zone distance shall be taken as the horizontal distance from a point 50 mm (2 in.) away from the open jamb to a point 50 mm (2 in.) away from the opposite jamb.
(b) For all center-opening sliding doors using single or multiple speed panels, the Code zone distance shall be taken as the horizontal distance from a point 25 mm (1 in.) away from the open jamb to a point 25 mm (1 in.) from the center meeting point of the doors.
(c) The average closing speed shall be determined by measuring the time required for the leading edge of the door to travel the Code zone distance.
2.13.4.2.3 Door Force. The force necessary to prevent closing of the hoistway door (or the car door or gate if power operated) from rest shall not exceed 135 N (30 lbf) (see 2.13.3.1). This force shall be measured on the leading edge of the door with the door at any point between one-third and two-thirds of its travel
