Practical Ways fo Cut HH [| iia a Costs in Carqo anaing = — a argo Handling F aci FOr HE new Grace line ships operate T on such a _ short schedule at ‘Seattle, that exceptional dispatch is neeessary. The ships arrive Satur- day 3:00 p.m. and sail Monday 10:00 a.m. The problem of the manage- ment* was to handle incoming and outgoing cargo to the two story shed in the Bell street terminal, in the fastest and most economical manner. The tidal range at Seattle required © that the equipment should be able to work into and out of side ports, a maximum of 16 feet below dock level and a rise of 8 feet above dock level. A partial plan of the Bell street terminal is shown in the illustration on page 32. This terminal includes an apron 20 feet wide with a railroad track. This track had to be available for car movements when the ships were not working the side ports. A survey and report by J. R. West, chief engineer of the port commis- sion, was adopted by the commission on Oct. 25. This report required moving two Barlow marine elevators ' that were installed on this pier in 1914 to the new locations to match up- with No. 1 and No. 38 side ports. It also meant the installation of Bar- low adjustable cargo platforms in the face -of the dock, so designed and built that they would enter the side ports at any stage of the tide and not have grades or ramps to work over, enabling the movement of cargo, al- ways on the level, to and from the ship by electric trucks, or by the tractor and trailer method of hand- ling. 30 Conducted by H.E.STOCKER race Line By H. E. Stocker To handle the valuable refrigerator cargo into No. 2 and 838 side ports, required the installation of a special Barlow marine elevator of the port- able type, which would work 16 feet below and 8 feet above dock and which could be moved away from the face of the dock and used for high piling in the sheds when the ships were not in port. The elevator manufacturers were instructed to have the _ elevators ready for operation at the time of the arrival of the first vessel, Dec. 18. This necessitated foundation work, sometimes at night to take advantage of the low tides, and it meant keep- ing traffic open both on the first and second floors and not interfering with the normal operation of the pier. This work was carried out as planned, and all -equipment was tested and in operation prior to the arrival ef the vessel. Within twenty minutes after ‘the Sanra Rosa made fast to the pier, cargo was being discharged; the opera- tion continued successfully and with- out interference, the work completed and the ship loaded according to sched- ule. This vessel arrived Sunday after- noon at 3:00 p.m. At. 12) o clock Monday night, the gangs were cut from six to three and the work car- ried on in No. 1 and No. 8 side ports and the after No. 6 hatch. Loading was completed well before sailing time, which was Tuesday, at 10:00 a.m. In working the cargo, the discharg- MARINE REVIEW—March, 1933 oy LY AAV!) as. w, ities at Seattle Stea mers ing was generally from ship to second story of the pier, via the elevators. The outgoing cargo from both second and first stories of the pier is handled in the same manner. On the first trip, there were dis- charged from the side ports about 420 tons of cargo and loaded througii the side ports over 570 tons. A very good showing for a new ship at a new dock and worked for the first time. The rise and fall of the vessel due to tide and load meant that the side ports were from 9 feet above dock to 8 feet below dock during this period and on Monday, Dee. 19, accompanied by the high tide there was a 35 to 40 mile wind—yet there was no slow- down in the loading. At one time the side port was 5 feet above the upper deck of the pier. The tractor, with two or three trail- ers came on to the large, fast movy- ing, inner platform of the elevator, and was raised or lowered until this platform matched up with the adjust- able outer platform, spanning the open face of the dock. When the load moved directly across and into the port, the speed of the platform is such that there is no slow-down or lost time. The width and length of the platforms, approximately 10 x 30 feet are such that two tractor trains can pass easily, giving a relay move- ment, one going and one coming. The elevator equipment was always ahead of the loading crew. It is the practice on this pier, when there are heavy loads to handle to and from motor trucks, to back
