(a) Temporary use permitted. Passenger or freight elevators being installed in buildings or other structures for permanent use may be used before completion of the building or other structure during construction to carry persons or material, or both, provided such elevators conform to the following requirements:
(b) Hoistway enclosures. The hoistway of any such elevator shall be enclosed with its permanent enclosure and permanent doors or such hoistway shall be enclosed with either solid or openwork material, except for access openings, as follows:
(1) Openwork enclosures shall be either wire
mesh of at least No. 18 U.S. gage steel or expanded metal of at least No. 18
U.S. gage. The openings of such openwork material shall reject a one-half inch
diameter ball. Such enclosures shall be provided with unperforated kick plates
installed at every floor level above the lowest floor. Where a counterweight is
provided such openwork enclosure shall be covered on the counterweight side
with wire mesh of not less than No. 18 U.S. gage steel with openings that will
reject a one-half inch diameter ball. Such mesh covering shall extend the full
width of the counterweight plus one foot on each side.
(2) Solid enclosures shall consist of
partitions of exterior grade plywood at least three-eighths inch thick or of
other material of equivalent strength.
(3) Every such enclosure shall be so
supported and braced that when subjected to a horizontal pressure of 100 pounds
applied at any point the resulting deflection shall not exceed one inch and
shall not reduce the running clearance to less than one inch.
(c) Hoistway doors. Where permanent hoistway doors are not in place, temporary hoistway doors shall be provided as follows:
(1) Every floor landing
opening in a hoistway enclosure shall be provided with a solid door extending
across the full width of the opening and not less than 78 inches in height. The
clearance between the bottom of any such door and the floor shall be not less
than one inch nor more than two inches. Each such door shall be provided with a
vision panel of not more than 80 square inches in area. Every such vision panel
shall be covered with wire mesh of No. 18 U.S. gage steel with openings which
will reject a one-half inch diameter ball. Each such hoistway door shall be
provided with a lock or latch which is openable from the hoistway side only and
inaccessible from the landing side.
(2) If the hoistway door at the lowest
terminal landing is locked automatically when closed with the car at the
landing, such door shall be provided with a means to unlock it from the landing
side to permit access to the car. Such means shall be accessible only to
designated persons.
(3) Where such
hoistway doors are of the vertical sliding type, they shall be of a type that
requires counterweights. Provisions shall be made for the containment of the
counterweights if their means of suspension should fail.
(d) Elevator car. Except where permanent elevator cars are used, temporary elevator cars used in permanent hoistways shall be constructed to conform to the following requirements:
(1) Frame. The frame of every such car shall
consist of a safety plank and vertical stiles gusseted to a crosshead
constructed of steel channels. Such frame shall be designed and constructed to
carry safely all the loads intended to be imposed thereon. Steel diagonal
bracing shall be provided to support the four corners of the car
platform.
(2) Platform. The
platform of every such car shall consist of a channel steel or aluminum frame
and steel or aluminum stringers assembled as a unit and secured to the safety
plank. Platform flooring shall be constructed of steel or aluminum plate or of
wood. If wood is used, it shall be of structural grade lumber not less than two
inches thick and shall be protected on the underside by steel sheeting of at
least No. 26 U.S. steel. Such flooring shall be securely fastened to the car
platform.
(3) Car enclosures. Such
temporary elevator cars shall be enclosed on the top and on all sides except
those sides used as entrance and exit openings. Such enclosures shall consist
of planking at least two inches thick, laid tight, or of other material of
equivalent strength. The top of every such elevator car shall have an emergency
exit opening in the enclosure of not less than 400 square inches in area with
the least dimension at least 16 inches. Such emergency exit openings shall be
provided with hinged hatch covers.
(4) Car doors or gates.
(i) Each such car shall be provided with a
car door or gate on the landing side. Such door or gate shall be at least six
feet in height and shall be of construction equivalent in strength to that of
the car enclosure.
(ii) Every
opening in such car door or gate shall be of such size and shape as to reject a
three-inch diameter ball.
(iii)
Every such car door or gate shall be equipped with an approved electric contact
so arranged that the car cannot be operated unless the door or gate is within
two inches of full closure. Such electric contact shall not be readily
accessible from within the car.
(iv) Such car doors or gates shall be of the
horizontally or counterweighted vertically sliding type. Where a horizontal
gate is used, such gate may be arranged to swing inward when fully
collapsed.
(5) Car
controls. The car controls of such elevators shall be so arranged that such
cars can be operated or controlled only from within the cars.
(e) Elevator operators. Such elevator cars shall be operated only by competent, trained, designated persons.
(f) Testing. Prior to the initial use of any temporary elevator installed in a permanent hoistway, such elevator shall be tested by a designated person. Such testing shall be in accordance with the following requirements:
(1) The car of such elevator shall be loaded
to its rated capacity and operated at its rated speed to the upper and lower
limits of its travel at least twice in order to test the operation of the upper
and lower auomatic limit devices as well as the operation of the hoisting
machine brake at various levels of the hoistway.
(2) With the rated load in place, the car
safeties shall be actuated by tripping the governor by hand while the car is
traveling downward at rated speed.
(3) Such test shall be repeated with no load
at least once every month while the elevator is in use by operating at a slow
speed and tripping the governor by hand.
(4) A written report of each test shall be
made and signed by the designated person making such tests. Such reports shall
include the dates, test loads and speeds involved as well as the test results.
Such written reports shall be kept in a log book on the job site available for
examination by the commissioner.
