728x90 Safety361 09. Electrical Testing It is more likely that this will happen during electrical testing and fault finding, when conductors at dangerous voltages are often exposed. You can minimise this risk if testing is done while the equipment is isolated from any dangerous source of supply, although this is not always possible. Take care to prevent contact with any hazardous internally produced voltages. The most serious injuries.. 2022. 12. 13. 08. Electrical Installation Electrical installations consist as the connection system that has the mission to conduct and distribute the electric current, from the electric service to the last electrical installation outlet, in a edification or construction. Electrical installation describes the physical work involved in installing electrical systems into a building and a plant., etc as testing of electrical wiring and equ.. 2022. 12. 13. 07. Coring on Existing Drainage Sump. Constructing holes in precast concrete manhole sections for pipe connections can be achieved by several methods. Each requires careful consideration before making the investment in training and equipment. Whether you are building a new plant and trying to decide which production method to use or you have an existing plant and want to determine if your current method is the most efficient, it’s i.. 2022. 12. 13. 06. Cable Pulling, Installation and Banding Cable pulling works involve an individual pulling sheathed cables through walls, trays and ducts for electrical power systems. They will push, pull, and band these cables through given spaces, as well as joining them together. 케이블 풀링, 설치 공사는 혼자하기 어려운 작업입니다. 한팀을 이루어 작업을 진행하고, 풀링할 때에 구호를 넣어 구호에 맞춰 케이블을 끌어당기고 고정하기도 합니다. 케이블을 따라 근로자가 일 해야하기 때문에 작업조건이 좋지 않은 경우가 많습니다. 작업할 수 있는 공간확보를 하는 것이 무엇 보다도 중요하고 .. 2022. 12. 13. 05. Bolt Tightening and Torquing [General Information] Bolts may seem simple, but in reality the proper manufacturing of bolted joints requires careful study. Tightening the bolt puts the shank in tension, counteracted by compressive forces on the contact surfaces of the head and the nut, transferred from the parts. Inadequate preload is a common cause for bolted joint failure, which is why it’s so important to use the appropri.. 2022. 12. 11. 04. Backfilling Work ㅠㅁExcavation and backfilling of soil is a very important part of construction process, and care must be taken while excavation in safety perspective. Different soil layers may be encountered while excavation, dewatering may be needed sometimes. These points must be kept in mind to take necessary action during excavation and backfilling. 주유원이 굴삭기에 주유를 하고 주유호스를 정리하고 있었습니다. 굴삭기 운전원이 소변을 보고 돌아와서 주유가.. 2022. 12. 11. 03. Asphalt Works Asphalt paving works is a composite material commonly used to surface roads, parking lots, airports and other such places. It lays the asphalt flat and provides minor compaction before it is compacted by a roller. 아스팔트 공사하는 모습을 운전하시면서 종종 보셨을 거예요. 많은 건설장비가 투입되어 장비사고 위험이 높습니다. 사용 중인 도로라면 교통사고 위험은 더욱 높아지죠. 2019년에 아스팔트를 싣고 와서 트랙터에 쏟아주는 과정에서 덤프트럭이 전도되는 사고가 있었습니다. 다친 사람은 없었으나 덤프트럭은 주요 부붐 및 거더가 손상되는 사고.. 2022. 12. 11. 이전 1 ··· 42 43 44 45 46 47 48 ··· 52 다음 728x90
