Among many notable recent successes, Hoist & Winch Ltd has come to the assistance of a large UK plant rental company with a very specific request. The company wanted a bespoke electric-powered winch lifting system to raise and lower large vinyl-type sheets in a purpose-built ‘wet area’. With no challenge too demanding, Hoist & Winch stepped up to the task.

At the heart of the Hoist & Winch system are four floor-mounted Yale RPE 400V three-phase winches offering 150kg swl (safe working load) and 20 Pfaff roof-mounted diverter pulleys coupled to four 12m long tubular spreader beams. Each winch raises and lowers one of the 12 m long spreader beams which attach to the vinyl sheet via load-bearing karabiner clips. Each vinyl sheet weighs approximately 60kg.

The customer can operate all four winches individually via their own wall-mounted, low-voltage pendant controls, allowing the lifting of a single vinyl sheet as required at any time. The innovative winch system raises the vinyl sheets safely and in a level position. This capability permits easy drying of the vinyl sheets after pressure washing, a process that removes any unwanted residual substances from the most recent hire job.

Each winch sits in purpose-manufactured mounting frames secured to the floor using four Hilti expansion anchors. The frame design allows orientation of the winch rope pay out at 90° to the first diverter pulley.

The room in which the washing, lifting, drying and lowering of vinyl sheets takes place is a purpose-built and enclosed ‘wet area’ with a cambered floor and drainage around the perimeter to support the removal of excess water during cleaning. Hoist & Winch Ltd provided PVC weather covers for the winch control panels to ensure safety at all times.

Ultimately, the system designed by Hoist & Winch Ltd significantly improves the whole operation to facilitate a quicker and far less labour-intensive turnaround of the vinyl sheets during busy periods of hire.

The scope of supply for Hoist & Winch Ltd included all pre-installation survey work to ensure correct the alignment and positioning of each winch, diverter pulley and all associated equipment, including top and bottom hook geared limit switches. The company also provided installation (using electric scissor lifts for working at height) over a seven-day period and subsequent commissioning. Further responsibilities included all wiring and load testing of the whole system. Once complete, Hoist & Winch Ltd issued a LOLER (Lifting Operations and Lifting Equipment Regulations) ‘Thorough Examination’ report.

To ensure smooth handover, Hoist & Winch Ltd undertook comprehensive operator training covering: overview of the winch units and main components; operating controls and features; periodic checks and lubrication; annual inspection, service and certification requirements; and practical operation by each operator.

Hoist & Winch Ltd Director Andy Allen says: “This project set out a number of important stipulations to which we had to respond comprehensively and efficiently. A successful outcome that meets with the project’s ambitions, delivered on-time and on-budget, is our primary aim. Once again our professional and experienced team of engineers here at Hoist & Winch Ltd came up with a safe, reliable, high-performance solution to the satisfaction of our valued customer.”

 When it comes to lighting, lumens and candela are the two metrics that are often confused. In this article, we’ll explain the differences and how this will help you select the perfect light for the job.

Lumens: Total Light Output

Lumens are the most common unit for measuring all the visible light from a given light source. Imagine the bare bulb or LED from a light inside the center of a large sphere. When all the light is measured inside the sphere it gives you the total lumen value of that light source. If the goal is to light a large area, lumens is the crucial metric for selecting the correct light.

Candela: Peak Beam Intensity

Candela is the standard unit for measuring peak beam intensity. Let’s imagine the large sphere from the previous example. Now, instead of the light being projected evenly over the entire surface inside the sphere, focus all that available light onto a specific section. This gives you the candela rating. If you need to project light in one direction or over a long distance, then candela is the crucial metric for selecting the correct light.

For example, sporting arenas use very high-lumen lights to bathe the playing field with a complete blanket of even lighting with no focused “hot spots.” The opposite end of the spectrum would be a police cruiser spotlight with a very high candela rating to pinpoint a suspect or a distant dark corner.

Choosing the Right Light for You

If you need even light distribution in an area, you should primarily consider lumens. On the other hand, if you require a focused, directional light source, then candela becomes a more critical factor. The ideal situation would be to combine both lighting styles into a single product. These types of lights are referred to as dual-light products. A spotlight features a tight, focused beam for distant illumination (candela) and a soft flood light to illuminate the area directly around you (lumens).

The Original Dual Light

Nightstick, a provider of professional LED products for industrial environments, firefighting, and law enforcement worldwide, created the original dual-light product in 2007. Often imitated but never equaled, Nightstick dual light products are the gold standard by which all others are measured. Visit Nightstick.com to find the perfect dual light for your job site.

If you are even asking yourself the question “should I be worried about explosive atmospheres (ATEX)” then the answer is most probably “yes”. The Dangerous Substances and Explosive Atmospheres Regulations (DSEAR) require employers to control the risks to safety from fire, explosions and substances corrosive to metals. This entails compliance with BS EN 1127 (Explosive atmospheres - explosion prevention and protection), which in turn requires that any electrical equipment used is intrinsically safe and complies with BS EN IEC 60079.

It is generally understood that equipment for use in more obvious hazardous locations such as flour mills, coal mines, petrochemical plants and fuel transfer facilities, needs to be certified “intrinsically safe”. In other words, incapable of igniting an explosive atmosphere. However, hazardous locations also include water treatment plants, tunnels and underground passageways or any location where a build-up of naturally occurring flammable material (such as methane or dust) could occur.

Most people are familiar with the definitions of ATEX ‘Zones’ and if not, a quick web search will bring them up. Put simply, Zone 0 means an explosive atmosphere is very likely and Zone 2 means it is unlikely, with Zone 1 being the “grey area” in between. It is easy enough to identify from its markings whether a particular piece of equipment is suitable for a particular Zone, e.g. Ex ia for Zone 0, Ex ib for Zone 1 and Ex ic for Zone 2. However, the onus is very much on the plant operator to ensure which parts of their plant are in which Zones.

As if the issue of Zones wasn’t difficult enough, there is also the consideration of which gases are likely to be encountered. For example, equipment marked as Group IIB must not be used in Zones with hydrogen or acetylene likely to be present. Those gases would require at least Group IIC certification.

Then there is also consideration of the equipment’s temperature classification, which specifies the maximum surface temperature that could arise due to a fault when operating within the specified ambient temperature range. For example, equipment coded T2 (>300C) could potentially get hot enough to ignite gasoline! However, a coding of T4 (>135C) is generally considered acceptable, being safe for all gases apart from Carbon Disulfide, which requires T6 (>85C).

Test Products International (TPI) believes it has greatly simplified things however, with the triple certification of the TPI 9080Ex Smart Vibration Analyser. The TPI 9080Ex is IECEx/ATEX certified for Zone 1 and North American approved for Class 1, Zone 1 and is hence certified for use in hazardous locations, with ANY gas types, ANYWHERE in the world.

The TPI 9080Ex offers on-meter analysis for detection of machine faults such as unbalance, misalignment, looseness and bearing wear. With full colour OLED display and Bluetooth communications, the TPI 9080Ex features colour coded alarms and zoomable on-screen vibration frequency plots with cursor readout. It can store lists (routes) of up to 1000 machines, each with up to 10 measurement points, with full waveform and frequency spectrum (FFT) capture.

The included free-to-use VibTrend PC-based trending and reporting software features high-end benefits such as automatic email notification of alarms and report generation to implement a full CBM strategy.  Routes and readings can easily be transferred to/from the TPI 9080Ex via Bluetooth using a smart phone or tablet running the free TPI Cloud Bridge App. This allows service personnel to be sent routes and return readings, no matter where they are in the world. 

In-line with TPI’s philosophy of being the value leader, the TPI 9080Ex has a list price of only £3,500.

A leading oil and gas Company needed thermal insulation for a tank at one of its lubricant plants. The upper surface of the tank, which reaches a temperature of 110 °C (230 °F), serves as a walkway for operators. This creates a high risk of employees receiving contact burns from the hot substrate. Additionally, some pitting corrosion had occurred. Finding a solution that would lower the surface temperature to prevent burns and halt further corrosion was crucial. 

Unprotected tank’s upper surface, operating at high temperatures. 

What was the Issue? 

The high temperature of the tank causes a hazard for the employees walking upon it. According to the guidance set forth by the Occupational Safety and Health Administration (OSHA), the maximum temperature for exposed surfaces that an employee could come into contact with is 60 °C (140 °F), in line with ASTM C1055. Workers must be protected from exposed heated surfaces, so it was crucial to lower the surface temperature of this tank to eliminate this hazard. 

In addition to its high temperature, the metal tank surface had been experiencing pitting corrosion, necessitating pit filling and a protective coating that would prevent it from corroding further. 

Why was Belzona Chosen? 

Having previously used various Belzona products, this Customer had confidence in their Distributors’ recommendation that Belzona 5871 was the optimal solution.  

As well as offering thermal insulation to protect employees from contact-burn injuries, this product only needs two coats, enabling quick turnaround times. It also has excellent corrosion resistance which was essential as the tank top had been experiencing pitting corrosion. 

Protected from high temperatures with Belzona 5871. 

How was the Solution Applied? 

The surface was prepared by vapour blasting the substrate to meet SSPC-SP10 (Near-White Metal) standards and was then degreased. Additionally, some corrosion on the top of the tank required pit filling with Belzona 1121 (Super XL-Metal) ahead of the coating being applied. 

With the surface prepared, the first coat of Belzona 5871 was then applied using a short-bristled brush. This product expands, reducing the number of layers which are needed, the first coat was applied at the target thickness of 1000 µm (39 mil) wet film thickness, which results in 3000 µm (118 mil) dry film thickness. The second coat was then applied using the same method six hours later. The tank was back to full service just 12 hours after the final coat was applied.

Surface preparation before application 

   Tank top after one coat of Belzona 5871 

What was the Result of the Application? 

This application successfully offered thermal insulation protection for a Fortune 500 oil and gas Company. Following the application of two coats of Belzona 5871, the previously dangerous temperature of 110 °C (230 °F) has been successfully lowered to a safe level—below 60 °C (140 °F).

This case study shows how Belzona 5871 offers thermal insulation and creates long-lasting safety and durability. The solution not only mitigated the risk of contact burns but also introduced a valuable layer of protection against corrosion.

The fact that Hart Door Systems has built a reputation for quality and longevity of its wide range of industrial doors, the importance of door maintenance should not be understated says Keith Fisher, Hart’s National Operations Manager.

Servicing industrial doors not only improves their reliability and operational functionality but servicing is also a requirement under Health, Safety and Welfare Regulations  which protect people who come into contact with the doors. Indeed failure to maintain industrial doors could put the user in breach of Government legislation incurring liability in the case of an incident involving an industrial door which is non-compliant.

As essential support for our clients Hart has comprehensive Service & Maintenance assistance as a specialist department which delivers a range of repair and scheduled maintenance options for its customers to further extend the life of their doors.

Given the very wide variety of industrial classifications we supply doors and shutters to, the emphasis has to be on designing servicing and maintenance packages which are tailored to match the specific needs of our clients’ businesses and the arising usage patterns of the various doors/shutters.

A preventative Servicing and Maintenance Agreement ensures Hart’s servicing is carried out correctly and at the precise frequency thus complying with Regulations. Typically during a Hart servicing visit all mechanical and electrical elements are checked for missing parts, general wear and tear and Compliance issues.

Mechanical checks include inspecting parts such as drive chain tension, alignment and lubrication, bearing wear and tear, motor oil levels and fabric tension and electrical checks include limit settings, cable connections and safety devices.

Hart also has a legal responsibility to ensure doors are left in safe working order after servicing. Again the issues are wide ranging such as measuring the closing forces of automatic doors where safe contact is the main strategy to prevent hazards.

The closing force of a door ensures correct force limitation under EN 12978 which prevents injury and crushing. Testing should always be carried out with an annually calibrated instrument according to DIN 18650, EN 12453 or EN 12445.

On completion of a Hart service visit, a paperless electronic copy of the engineer’s report will be issued which may include additional recommendations necessary to ensure the doors are safe and compliant to relevant legislation due to changing ‘shop floor’ circumstances.

The sophistication of door systems such as Hart’s Speedor range or its Typhoon shutter range has changed significantly over the years to cater for changing needs by its customers across the globe and indeed by changing climate. To ensure hard working doors in busy industrial environments continue to make a significant daily contribution to efficiency and safety, planned maintenance is essential.
