Compact Wheel End Ideal For Commercial Vehicles

Components manufacturer SAF-Holland has designed SAF 60 One, a compact wheel end targeted at commercial vehicle manufacturers, fleets and freight transport companies. For commercial vehicles, less weight means a useful load gain and less diesel consumption. SAF-Holland, which supplies axles and air suspension systems as original equipment for semi-trailers and trailers, believes that, with today's chassis, weight-saving potential is practically exhausted, for example, through wall-thickness reduction in the axle tube or the lightweight construction of suspension systems.

One area where further weight reductions are possible is wheel ends. The 120mm and the 0mm offsets have been standard in the commercial vehicle industry for many years. SAF-Holland said both the 120mm and the 0mm have very different strengths, but one common weakness: their respective advantages are not interchangeable, or at least have not been to date. To make weight reductions possible, the company has designed SAF 60 One, a compact wheel end with a new wheel offset of 60mm. This is said to allow a weight reduction of up to 204kg for a tri-axle and make it possible to have standard wheels for axles with disc or drum brakes as well as for tractors and trailers.

This offers potential for vehicle manufacturers and, in particular, for fleets and freight transport companies. SAF 60 One means instead of 120mm and 0mm offsets, there will in future be only one wheel end with a 60mm offset. This can be equipped with disc or drum brakes and have steel or aluminium rims. Moreover, it can be used for the tractor and for the trailer. SAF 60 One has been designed for axle loads of nine to 10 ton.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
