Lifting Bags Enable Safe Movement Of Heavy Loads

A range of industrial-grade lifting bags and controls has been introduced by Enerpac for lifting, pushing, pressing or moving loads safely and smoothly. Enerpac offers nine sizes of the low-clearance lifting bags, which use compressed air up to 116psi (8 bar) or water to achieve load capacities ranging from 3.1-67.2 ton (27-656kN). The lifting bags feature a high-friction surface to provide increased safety for applications in construction, earthmoving, engineering, manufacturing, mining and energy, quarrying, oil and gas, primary production, heavy transport and machinery, marine, maintenance, materials handling and safety sectors.

Enerpac lifting bags, which are Kevlar reinforced and 'centre target' marked for optimised safety in use, complement a range of high-pressure (700 bar) hydraulic lifting equipment engineered by Enerpac to pack more lifting power into a smaller space and make cylinder placement simpler and safer. The lifting bags are offered alongside Enerpac's system of plastic cribbing blocks and wedges, designed to optimise safety when stabilising heavy loads after they have been lifted.

Features of these lifting bags include: collapsed heights from 28-31mm for easy access under and around loads, with extended heights from 157-541mm; aggressive high-friction surface to prevent bags from slipping - they can be stacked up to two bags high for extended lifting capabilities; non-conducting rubber, which resists oil and most chemicals and has an operating range from 0-90C; 25 ton and larger sizes have integrated Nylon straps and heavy-duty reinforced lugs; industrial interchange air supply to deadman controller; and safety coupler inflation hoses that protect against accidental disconnections.

Tony Brooks, Enerpac's regional manager, Australia and New Zealand, said that advantages of lifting bags include easy access to restricted spaces, such as those around awkwardly shaped loads or loads in confined spaces, for example. The bags can also tolerate restricted surface pressure.

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.
