HBM Helps Del's Tail Lifts Meet New Regulations

Del Equipment has utilised HBM's data acquisition and analysis equipment to ensure its range of tail lifts meets the UNECE Whole Vehicle Type Approval regulations ahead of implementation. Del designs and manufactures 30 main variants of tail and bin lifts, all of which need to gain component approval. To achieve this, Del had to statically test the complete range of rear under-run protective devices that forms part of the tail-lift configuration.

'We had to ensure that our under-run bars met the strength requirements of the regulations and so we needed accurate force-measurement equipment,' said Amir Tabatabai, mechanical-design engineer at Del. Tests were conducted at Del's factory at Witney in Oxfordshire using an in-house developed rig fitted with a hydraulic ram that could easily slide to different positions for testing alternative points on the tail-lift construction if necessary. Forces were measured using an HBM U10M transducer with TEDS (Transducer Electronic Data Sheet) connected to a QuantumX MX840 for data capture, while the analysis was carried out using HBM's Catman Easy software.

HBM's engineers visited Del to see at first-hand what the company was trying to achieve and to get a better idea of its requirements. As a result of co-ordinating with Del, HBM was able to recommend the best equipment for the job, in this case the U10M force transducer because it substantially reduces cross-talk between bending moments and lateral forces through its integrated, patented compensating circuit.

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.
