# Mechanical Plant Sections
8.31
These Sections, in Hong Kong and Kowloon, each under a Section Manager of Technical Superintendent Grade are now divided into three Sub-Sections.
8.32 The Heavy Plant and Steam Sub-Sections are responsible for the installation and maintenance of generators, pumps, steam boilers, swimming pool filtration plants, oil fuel systems, autoclaves, sterilizers, compressors and mobile plant such as road rollers.
8.33
The General Engineering Sub-Sections, which include the Machine and Fitting Shops (responsible for milling, turning and grinding components of machinery), are responsible for the maintenance and repair of small engines and gardening equipment, hydraulic systems of vehicles other than braking systems, laundry and dental equipment, school equipment, printing and post office machinery, the upkeep of air compressors and the installation and maintenance of masts and aerials.
8.34 The Parking Meter Overhaul Workshop, Instrument Repair and Engraving Section in Hong Kong form the third Sub-Section. At the end of last year certain changes were made in respect of the responsibilities of the then Parking Meter Section. The outdoor Depots became the responsibility of the Transport Department with effect from 1st April 1974 and that Department also assumed responsibility for fault calls, minor adjustments and repairs to meters and their removal and re-instatement. The Overhaul Workshop continued to complete the overhaul of meters, major repairs, reconditioning of casings, dump chutes and collection trolleys and conversions to new charge rates. The Instrument Repair and Engraving Shops continue with the repair of instruments and engraving work of all types respectively.
# PLANT OPERATION SUB-DIVISION
8.35
This Sub-Division is responsible for the operation and maintenance of major plant and consists of six Sections Incineration Plants and Abattoirs, Air Conditioning Plants, Hong Kong International Airport Services, Hong Kong City Hall, Lion Rock Tunnel and Hospital Services. The majority of these plants are required to provide a 24-hour year-round service.
# Incineration Plants, Abattoirs and Compost Plant
8.36 Three of the four lines of the Kennedy Town Incineration Plant were in almost continuous operation throughout the year and there were no major breakdowns. A rise in the consumption of oil, used to assist in burning, was experienced in the first quarter due to very wet refuse. During the year refuse was analysed to re-determine the paper, plastic and moisture content. A seven-day shut-down of the plant was necessary to enable work in connection with the new Fifth Line to be carried out. The opportunity was taken then to carry out furnace refractory repairs.
8.37 All Lines of the Lai Chi Kok Incineration Plant 'A' were in operation most of the year, but during the second quarter lines operated on reduced load to enable refractory repairs to be carried out. Staff were posted to the Lai Chi Kok Incineration Plant 'B' during the period under review to assist in the commissioning of the new Plant including the burning of refuse trials.
