(a)
Car travel.
New gravity elevators shall not have a car travel
					 in excess of four stories, or 60 feet.

					 landing.
(e)
Counterbalancing.
When two cars of gravity elevators are so
					 arranged as to counterbalance each other, the hoisting cables shall be properly
					 secured to the car beams. The use of mechanisms on the car beams of such
					 elevators for car adjustment to various floor levels is prohibited.
(f)
Latches.
Latches shall

					 gravity elevators shall be provided as required by §
											7.281 (relating to elevator

					 control the speed of the car during ascent or descent. Such brakes shall also
					 function to automatically hold the car immovable and secure at any landing at
					 which it is standing.
(i)
Speed governors.
When the car travel of gravity elevators is
					 over two stories, or 30 feet, a centrifugal speed governor shall be provided
					 which will control the speed of the car in its descent.
(j)
Car safeties.
The cars
					 of gravity elevators shall be fitted with substantial car safeties.
(k)
Cable or rope locks.
Gravity elevators shall be provided with a cable or rope lock which, when
					 locked, will prevent the car from being operated from any other floor or
					 landing.
(l)
Gates.
The gates for new gravity elevators shall be of the
					 semi- automatic type, except that at terminal landings they may be of the full
					 automatic type. Existing gates shall be replaced by new equipment if the
					 Department so requires.
