9 MAY 2022 WorldWide Drilling Resource® OZ Lifting Launches Spark-Resistant Range OZ Lifting introduced two spark-resistant products - a chain hoist and push beam trolley - both available from a complete capacity range of 0.5, 1, 2, 3, 5, 10 tons to cover most likely applications. The Minnesota-based manufacturer targeted the products at applications where gas or dust particles could create a spark. Markets include gas and oil, mining, wastewater, and others where an explosive atmosphere exists. As with other manual chain hoists in OZ’s catalog, 10-, 15-, 20-, and 30-foot heights of lift are offered as standard, with custom lengths available on request. All chain hoists and push beam trolleys are painted white, but distributors and end users could recolor them to suit protocols at specific facilities. Key features of the hoists include a unique hand wheel design; minimal load lifting effort; fully enclosed gearing; stainless steel or copper components; and suitability to lifting and pulling applications. The push beam trolleys boast precision ball bearing, copperplated trolley wheels and lifting bale; copper-riveted identification tags; antidrop plate; and compatibility with most I-, S-, and W-beams. “The products go hand in hand,” said Steve Napieralski, president at OZ Lifting. “We saw a need in the market for spark-resistant manual chain hoists, and if you are going to offer them, you typically will be hanging the equipment from a trolley that also needs to be spark resistant. However, the products can work independently of each other.” For a link to this website, visit this page at: worldwidedrillingresource.com Environmental Monitoring by Thomas Kwader, Ph.D., P.G. Owner, Qwater Well Developer and WorldWide Drilling Resource® Hydrogeologist Conserving Groundwater - We Must All Do Our Part We all have a good understanding of the water cycle, which involves rain falling on the porous land surface, which then helps recharge the shallow aquifers below. Those aquifers provide water to our wells for irrigation, drinking water, and other potable uses. Groundwater levels tend to fall or drop when we pump groundwater out of the aquifer faster than it is recharged - primarily by rainfall. There isn’t much we can do to increase rainfall rates, but we can minimize surface runoff rates by allowing more water to soak into the soil and less to travel downhill along impermeable surfaces such as roofs, concrete, and asphalt surfaces. Groundwater recharge can be increased by retaining runoff on permeable surfaces such as grassy surfaces and retention ponds with permeable bottoms which can aid in groundwater recharge. Agricultural irrigation and high-density housing (i.e., ¼-acre or less lots) with irrigation wells can cause extreme lowering of shallow groundwater tables which, in turn, can affect deeper aquifer recharge rates. Over time, these diminished recharge rates can cause regional groundwater declines. The lowering of groundwater levels can also cause drying-up of wetlands, lakes, springs, and even cause land subsidence and increase sinkhole activity. To prevent these effects from lowering groundwater levels, we should minimize the use of groundwater in sensitive areas and use best practices for agricultural irrigation, as well as encouraging the capture and retainment of rainfall and runoff rather than draining excess surface water to streams and rivers, and allow more recharge to the surface aquifers located in upland areas.
