The full load capacity shall not exceed 750 lbs.(12)Speed. The contract speed shall not exceed 25 feet per minute.(13)Travel. The total travel of lifts serving more than one floor shall not exceed 25'.(14)Control Operation. The car shall be operated from the landing opening only by key-operated continuous pressure switch.(15)Guide Rails. Steel guides shall be used on all installations.(16)Car Safety. Cars suspended by ropes or chains of the winding drum type shall be provided with a car safety located within the car frame.

The electric system shall be so interlocked that due to electrical power failure, the car platform will remain in the position to the power failure and will move only on the resumption of power when the operating key switch is activated to start operation.(19)Hydraulic Valves. An overload relief valve shall be installed in the hydraulic circuit to prevent operation of the platform if loaded above rated capacity.(20)Mechanical Stops. Mechanical stops shall be installed to prevent lifting platform from traveling above the predetermined level.(21)Hydraulic Piping and Connections. Flexible hose and fittings may be installed between the check valve or control valve and cylinder if they comply with the following requirements: Steel wire reinforced rubber covered hose shall have a bursting strength of ten times working pressure and the hose must be replaced at least once every six years.(22)Ropes and Chains. Car platforms suspended by ropes or chains shall have not less than 2" steel ropes or equivalent number of steel roller or multiple link steel chains. Rope or chain fastenings may be thimbles and clamps or other approved type of fastening.(23)Safety Factor. Suspension of car platforms by ropes or chains shall be at least six.(24)Slack - Rope - Chain. A slack rope or slack chain switch shall be installed in connection with all machinery of the winding drum type which will automatically shut off the power and apply the brake and stop the machinery, if the load carrying platform is obstructed in its descent.(25)Voltage. The maximum system or circuit potential permitted in the hoistway or landing operating devices shall not exceed 240 volts.(26)Riders. All persons are prohibited from riding on a casket lift.(27)Signs. A sign shall be provided on the car in a conspicuous location with letters at least one inch reading CAPACITY 750 POUNDS.

The owner or his agent in a building in which a lift is installed or altered shall arrange for an inspection with the authorized division of state, city or town inspection department of not less than one year.(30)Plans. No casket lift shall be installed or altered until plans and specifications of such installations or proposed alterations shall have been filed by the owner of the premises where the lift is to be installed or altered with the inspector or manufacturer, and a certificate of approval of requirements shall have been issued by him.(31)Fees.
