It is recommended that this potential problem be reviewed with the belt supplier prior to installation. Approved a901 will be published periodically. All elevator bolts used for join- ing the belt or securing handholds or steps to the belt shall be installed and maintained so that the heads do not project beyond the inner surface of the belt see Table 4.
Each safety stop shall be tested individu- ally. Steps or platforms shall be not less than 12 in. No ladder passage through a floor or platform is required.
A time delay switch may be required as part of an electronic device installation to permit passage of asne steps. The overlap of the belt at the splice shall be not less than 3 ft 0.
Corners of gates shall be rounded. Search the history z90.1 over billion web pages on the Internet. Head shaft, couplings, collars, and keys Vibration or misalignment in drive Be ready to pull rope in case of a misstep.

Head-pulley lagging shall be changed in conjunction with belt replacement. After the manlift has been stopped by an automatic 9a0.1 stop, it shall be necessary to reset the electrical control circuit manually. Safety switches on movable hoods The breaking strength of the manlift belt shall be not less than 30, lb N minimum tensile strength for belts with ft 30 m of travel or less; 44, lb N minimum tensile strength for belts with to ft 31 to 46 m of travel; and.
Skipping when mounting step check drive train The SI units have been directly softly converted from the Customary units. Top pulley and lagging If located in buildings to which the public has access, manlifts shall be located in an enclosure protected by self-closing, spring-locked doors.
