Pierre Du Plessis, Sales and Marketing Development Manager for Allison Transmission in South Africa, said, "Allison is proud to be the exclusive supplier of the entire range of Bell's articulated dump trucks. Allison 2000, 3000 and 4000 series gearboxes Super durable and superior in Bell truck applications, it is ideal for extreme conditions of extreme use." Bell's partnership with Allison began in the 1970s. The company was founded in 1954 as an agricultural solutions provider with Allison transmissions on its tractors. Today, the company is equipped with Allison transmissions in its full range of articulated dump trucks and tractors. “Our mines, quarrying, construction and agricultural machinery users have long relied on the reliability, smooth shifting and low fuel consumption provided by Bell vehicles and equipment, which is also attributed to the Allison transmission,†Bell Equipment Tristan du Pisanie, product manager of the company's articulated dump trucks, said, "Efficient and advanced gearboxes help us provide our customers with industry-leading solutions, always at the forefront of technology, focusing on reducing operating costs and enhancing the user experience." Based on the 3000 Series product platform, the 3400ORS gearbox is designed for Bell's 30-tonne heavy-duty trucks, offering unparalleled durability and increased value in the vehicle's lifecycle. The gearbox uses xFE high-efficiency fuel-saving technology to optimize the speed ratio, making the torque converter more locked, extending the running time of the gearbox in the high gear and low engine speed, thus significantly reducing fuel consumption. The Allison transmission increases productivity by increasing the acceleration of the articulated dump truck, increasing the average speed and increasing the average number of runs per day. In addition, the Torque Converter with Continuous Power TechnologyTM combines with a high-powered engine to improve vehicle performance and vehicle handling for industry-leading load capacity. Bell vehicles also feature DynActiveTM dynamic shifting, which adjusts shift points based on vehicle weight and road grade to further optimize fuel economy.
Couplings are used to connect two joints of TUBING coupling or CASING pipe together.
Couplings are short length of heavy wall pipe with the same threads on each end.
The steel coupling is mainly used to connect oil pipes in pil drilling.
This product can be used to connect the shafts of units that are
manufactured separately.
It can fit the misalignment of the shafts or introduce mechanical flexibility.
The pipe coupling is capable of reducing the transmission of shock losds from one shaft to another.
It can also introduce protecyion against overloads.
The steel coupling can be used to alter vibration characteristics of
rotating units.
Pipe coupling is also used to connect drilling par and driven part.
