Harrington Hoist, a supplier of electric and air-powered hoists and trolleys, will display its newly-released NER/ER electric chain hoist. The ‘quiet’ hoist has new motor, load brake and inverter components. It uses a nickel-plated load chain to lift from 0.11–18t.
The product features upper and lower limit switches designed for low headroom. The models are not only offered in standard single speed, but alternatively can be purchased with under-the-cover variable frequency drives functioning at dual speed. Depending on the model, the product can have up to six pocket load sheaves.
Count per hour meters, which record running time between servicing works, are standard on both the NER and ER models and contribute towards the UL-approved standards of safety and maintenance. The failsafe maintenance-free brake uses Smart Brake Technology and has a 10-year warranty.
Harrington says its hoists are ‘environmentally friendly’ as they are not fabricated using harmful materials, plus they are energy-efficient.
Harrington Hoist will also show the UBC Universal Beam Clamp, released in January to complement Harrington’s range of electric and air powered hoists and trolleys. It will be available in capacities ranging from 1–10t.
The clamp features a built-in suspension pin to be used in environments with low headroom and an opening jaw that can be adjusted for different tapered and flat-flanged beams. An optional suspender is available as an add-on feature, and can be used for oversized hooks and perpendicular mounting.
Harrington designed the clamp for use as a hoist anchor point in temporary overhead lifting and vertical rigging operations, but it can also be used as a below-the-hook lifting device. Another potential application is to use it to hold and position beams during construction.
The beam clamps have been designed to comply with standards of the American Society of Mechanical Engineers (ASME), a not-for-profit engineering standards organisation.
Specifications fulfill the criteria for ASME BTH-1 structural, mechanical and electrical components, and ASME B30.20 applying to marking, construction and use of the clamps. They also comply with portions of ASME B30.16, with a design factor minimum of 5:1 for meeting additional requirements.
