34 June 2018 powered haulage continued Engineering controls are designed to minimize the impact of hazards that cannot be eliminated or substituted. For mobile equipment, engineering controls can take the form of active control, such as interlocks that prevent or stop the machine from start- ing or running until a designated choice is made by the operator. Other examples in- clude ignition switches and the seat belt switches. These are considered active con- trols because they can stop machine opera- tion until a designated action is taken. Engineering controls have advantages and disadvantages, Hill explained. "One of the advantages is that it does require the operator to use the seat belt to operate the machine," Hill said. "On the other hand, some devices can be complex." Administrative controls promote the use of seat belts by influencing the behavior of the equipment operator or mine man- agement and require action by at least one individual. An example is a warning light that reminds the operator to fasten the seat belt prior to operation. Warning devices, such as warning lights on the exterior of the cab or high-visibility seat belt covers, are other examples of devices that can indicate to mine management whether the operator is wearing the seat belt. "These are consid- ered passive systems because they promote the use of seat beats by influencing the be- havior of equipment operators and mine management," Hill said. "The disadvantage of this type of control is that it is ineffective for those equipment operators who refuse to wear their seat belts." Despite the efforts of awareness cam- paigns and training programs and work- place policies, a certain percentage of U.S. Tsubaki Power Transmission LLC is a leading manufacturer and supplier of state-of-the-art power transmission and mo- tion control products and is a global leader in roller and conveyor chain production. U.S. Tsubaki is the largest global subsidiary of Japan's Tsubakimoto Chain Co., which was founded in 1917. Today, Tsubaki's products are marketed in more than 70 countries. U.S. Tsubaki's corporate headquarters and main distribution warehouse are just outside of Chicago in Wheeling, IL, and it has full manufacturing facilities in Holyoke, MA, and Sandusky, OH.

The TSUBAKI name is synonymous with excellence in quality, dependability and cus- tomer service. An intense focus on research and development, along with constant mod- ernization of its production facilities are among the key components in Tsubaki's ability to successfully meet the ever-chang- ing needs of the marketplace. Leveraging its vast, international network of corporate and industrial resources, U.S. Tsubaki offers cus- tomers the finest power transmission prod- ucts in the world as it strives to be the "best value" supplier in the industry. Tsubaki's global presence affords the company unprecedented opportunities to market advanced new products and technol- ogies, and to utilize the intellectual assets of what it characterizes as "some of the bright- est minds in business and engineering from around the world." This strength, combined with its continuous improvement of quality and processes, has U.S. Tsubaki poised for lasting growth now, and well into the future. U.S. Tsubaki's industrial group is cur- rently comprised of four business units: the Roller Chain Division, Engineering Chain Division, Power Transmission Components Division (which includes Sprockets) and the KabelSchlepp Cable & Hose Carrier Division. The Roller Chain Division provides some of the most versatile products on the market. Tsubaki innovations have yielded popular problem solvers such as selflube Lambda® series chain, corrosion resistant Neptune® chain, fatigue resistant Super Chains, and rugged Energy Series™ oil field chains. At- tachment chains used for conveying a vari- ety of products are also available in a range of configurations. U.S. Tsubaki's Engineering Chain Divi- sion starts with high-performance base ma- terials to ensure increased wear life. They offer heavy-duty chains designed specifically to meet the demanding needs of a vast array of industries—all designed to prolong wear life under rigorous operating conditions. U.S. Tsubaki sprockets are built from top- grade, heat-treated carbon steel to offer long wear life, resist abrasion, and withstand heavy shock loads. Alloy and stainless steel sprock- ets are also available for extra corrosion resis- tance and food-grade applications. Precision manufacturing at their ISO-certified facilities ensures that every U.S. Tsubaki sprocket stands up to critical design specifications and meets the highest quality standards. Power Transmission Components prod- ucts include all Tsubakimoto products other than chain and sprockets. A partial listing consists of belts, cam clutches, actuators, dampers, overload protection and reducers. The Cable & Hose Carrier Division sup- plies steel, high-grade stainless steel, solid plastic cable carriers and hybrid cable car- riers with aluminum stays and plastic side- bands, in standard sizes or tailor-made to an individual customer's exact size and applica- tion requirements.
