Power is provided to the south bascule leaf by means of a <br />submarine cable. Backup power is provided by a generator located off-site. The power supply is 240 Volts AC. <br />Mech/Elect (06/01/2021) There are no arc flash labels on the cabinet. The cabinet is very dusty. <br />Four cabinet sections of the MCC don¿t have door handles/locks to close the cabinet doors. <br />Some components of the power system are old and may soon be phased out by the manufacturer. The components still function <br />normally. <br />(5/8/2023) Condition still present. <br />Double traffic gates are located at near end of the bridge, an advance gate and a traffic gate closer to the center of the span. Each <br />gate has three flashing red lights mounted along the length of the gate arm. The gate arms are actuated by an electric motor and <br />stopped with a brake. There is also a ringing bell on each traffic gate. <br />Mech/Elect (06/01/2021) South Gates: Lever arm and main axle bearings are worn. The brake adjustment of the down stop is loose. <br />North Gates: There is a noticeable failing bearing noise (either motor bearing or gear reducer bearing). Drive machinery needs <br />lubrication--axle bearings, lever arm bearings, and gears. Brake pads are not contacting the brake drums for up and down position- <br />-adjust the limit switches for proper brake pad operation. Gate enclosure is damaged and door hinges are broken. <br />(5/8/2023) Condition still present. <br />Two sets of single traffic gates are located near the north end of the bridge and at Piers 3 and 7, south of the bascule span. Each <br />gate has two flashing red lights mounted along the length of the gate arm. The gate arms are actuated by an electric motor. <br />There is an alarm bell on each traffic gate. <br />There are 2 double flashing signal lights each side of the bascule span. One is mounted on the cantilever arm and one on steel <br />signal pole. <br />Mech/Elect (06/01/2021) The splices for the arm lights are not spliced/sealed properly and are exposed to wet conditions. One light <br />on the south traffic gate arm was not lit. One light on the north gate was not lit. <br />(5/8/2023) Condition still present. <br />The bridge house is a reinforced concrete structure located on the west side of Pier 12. The bridge house contains the control <br />panels and circuitry and provides access to the north bascule pit. <br />The bridge house is a reinforced concrete structure located on the west side of Pier 12. The bridge house contains the control <br />panels and circuitry and provides access to the north bascule pit. <br />(5/8/2023) There are multiple ceiling light coveres in the control house that are missing.
