Bark gets sorted with EQM

EQM Industrial has once again proven it looks at the big picture when it comes to recommending the most appropriate equipment to be used for optimal performance.

Anthony Bloxham from EQM says they were recently posed a question on what would be the most suitable gearbox for a conveyor that would operate outside in pretty harsh environmental conditions. 

“The customer wanted something that would last a long time withstanding harsh weather conditions and continue to work all day, everyday, if required.” 

The client was a landscape supply business that handles many different grades of bark. 

The business wanted to increase production and decided to look for a new conveyor system that would separate the bark from the cadmium in each specific grade. 

They initially looked offshore but turned their attention to EQM because if there was a breakdown, they could quickly source replacement parts or equipment. 

When others would have suggested a conventional worm gearbox, EQM stepped it up and suggested the STM OM series of Bevel Helical Gearboxes, which comes with a cast-iron gearbox housing and hardened steel gears instead of an aluminium housing and brass gears as alternative. 

“It’s more designed for rugged and heavy duty loads and can withstand pretty hard weather.” 

In fact this exciting range of STM Bevel Helical Gearboxes is second to none, with a broad and full range of sizes and ratios, a variety of mounting options and the ability to transmit torques up to 11,000nm. 

“Each drive needed to deliver power and efficiency, have a high service factor to be long lasting and require minimal maintenance.”
As standard, and due to the harsh conditions, EQM also recommended and fitted Challenge triple seal spherical bearings to all the drive and tail drums. 

A simple alteration to strengthen EQM’s standard C-Channel and TR series designs provided all the bark processor needed to achieve his requirements. 

The client also found that with EQM they got more than they actually bargained for in the way of service and support.
“At the end of the project we gave them a full maintenance schedule including information for ordering replacement parts and suggestions on how often to lubricate the equipment.”

Contact EQM today to make your processing line productive with the right gear drive and simple innovative conveyor designs to suit your needs.

Verbal or written assurances for Health and Safety compliance not enough

Recently the news media communicated, somewhat inaccurately, the notion that the soon to be amended Health and Safety legislation was contemplating the incorporation of Manslaughter charges in cases where employees had died in or around a company’s environment. This communication was very quickly rebuffed, but what became abundantly clear is that the new Health and Safety legislation is designed to catch senior business leader’s attention. 

Directors and companies are liable for fines up to $600,000 if it is proved they could have or should have done more to prevent serious injury. In addition if a company, and or its leader/s, are found to be negligent in their duties and an employee was critically injured then a jail term of up to five years may be incurred. 

Recent well-publicised events where loss of life, or serious injury eventuated, has resulted in some stiff penalties being enacted under the new legislation. For senior leaders having verbal or written assurances that their organisation is complying with the requisite Health and Safety standard is not going to be enough. It is imperative that organisations have visible proof that their Health and Safety policy is alive and well in the organisation, but more importantly is being adopted, embraced and managed by all levels of the organisation, not just the shop floor. Being independently certified to a standard that is globally recognised is a solution that many companies are moving towards. 

It provides business leaders with an independent verification that the company is on top of it its game and is putting its best foot forward to minimise or mitigate risks that might result in a serious or fatal injury being sustained. New Zealand’s leading Management System Certification body, Telarc, has recently noticed a significant increase in enquiries to evaluate and audit New Zealand businesses against an internationally recognised Health and Safety standard such as AS/NZS 4801. The belief in the market is that because of the new Health and Safety legislation organisations need to have in place a management system with international recognition to minimise the potential for transgressions and or subsequent legal action. 

As organisations look at ways to mitigate risks and protect themselves and staff, it makes sense that preventing injury or death is smarter than possibly facing a time consuming, expensive and potentially crippling legal action. More and more New Zealand organisations are looking closely at their social and corporate responsibilities to not only protect workers but to identify and actively manage and minimise risk. It is a fact that certification reduces risk considerably and provides comfort and peace of mind at all levels that the organisation is doing everything in its power to protect their employees and business.

Modular filtration covers large range of applications

Egmont Air has a new modular range of dust collection systems for filtering fine dust particles and powders.

Cartridge filtration technology can provide a guaranteed clean-air discharge for micron-sized particles. Different media options such as fire-retardant, PTFE and anti-static cartridges mean they filter units can be specified for a large range of applications including; hot smoke and fume, oily smokes and dust particles, volatile powder and solvents, etc. 

In a recent project for fine volatile powder, an antistatic media was used to reduce possibility of static charge, as well as many other safety features, such as vertical-discharge explosion relief panels and Atex non-return valves for maximum protection. 

The Filter system captures the fine particulate at the source to prevent the powder from dispersing into the operators breathing zone or around the factory. This has provided a clean and safe workshop while ensuring that the operators breathing zone is protected.

The system is also very easy to maintain, with quick-release bins for collecting the residue powders and a fully automatic filter-cleaning system which provides continual cleaning of filters to maintain optimum filtering efficiency, filter condition and discharge air quality.

Egmont Air can also specify systems with an eco-power saving device which controls fan speed and energy savings when various outlets are switched off. “A small 20 percent reduction in airflow will provide a large 50 percent power consumption saving – this is something that provides immediate payback to lean-conscious manufacturing facilities.”

Egmont Air, specialists in dust and fume extraction provide solutions for all dust and fume extraction applications including technical on-site evaluation of hazardous area and chemical processing situations. A full range of filters, bag-houses, dust collectors, fans, modular duct and flex is available in NZ.

Innovation in hand protection

The hand is vital to our day to day life, carrying out 70 percent of our total motor abilities and providing us with exceptional mobility and agility. Innovation in the design of protective gloves has resulted in a range of solutions for industry specific hazards. 

One of the most common requests that we receive at Lynn River is for a glove that can stand the rigours of manufacturing, construction or engineering environments while providing excellent dexterity, grip and providing a barrier to a range of fluids. 

Until recently this challenging brief usually involved a degree of compromise on at least one of the variables of comfort, grip, durability or liquid resistance. That is until the R&D team at Showa put their thinking caps on and solved the problem. Innovations in the manufacturing process have led to the development of gloves such as the Showa 377 and 477 that answer this challenging brief in full and without compromise. 

The Showa 377 starts with a glove liner created on Showa’s legendary “Ergo Fit” formers that mimic the natural curvature of the human hand which in turn leads to a reduction in hand fatigue. Next the ultra-thin sky blue Nitrile coating is applied over the full surface of the liner to provide an impermeable surface making it ideal for working in damp or greasy environments. This nitrile coating has the advantage of providing protection against a wide range of chemical substances. Finally, the black nitrile foam over dip ensures excellent grip is achieved for the wearer even in oily applications. These gloves are both thin and tough allowing precision work to be carried out even in the most demanding of conditions. 

Not to be outdone, the geniuses in the R&D team then went one extra step further and created the Showa 477. This version follows similar design properties as the Showa 377 model but has been created using a thermal liner for extra protection from the elements. 

To find out more about these innovations, contact your local safety distributor or call Lynn River’s Customer Services team on 0800 10 45 68.

Extending chain life

Power transmission and conveyor chain are the two common chain drives found in industry, and although their purpose is different, what is common with chain drives is that they wear. The phrase “stretch” is frequently used when referring to the level of elongation of a chain.

The reality of chain elongation is each chain link consists of a collection of surfaces which slide against each other as the chain articulates, such as wrapping around a sprocket. Plain bearing surfaces provide high load carrying capacity for small shaft dimensions in comparison to rolling bearings, but also have lower speeds due to higher friction with sliding surfaces rather than rolling.

On a typical roller chain, a pair of bearing surfaces can be found at every pin on both the inner and outer plates, and the wear of these surfaces determine elongation. The allowable elongation of chain depends on the application, however less than 2% increase in length for transmission chain is common. Although this may seem insignificant, this elongation will cause the chain to start riding up on the sprocket teeth and in more extreme cases can ‘jump off’. Once a chain begins to elongate, the level of wear will begin to accelerate on both the chain and sprockets till catastrophic failure or replacement.

Minimising chain elongation can be achieved by the following:

  • Improved lubrication.
  • Reducing chain tension.
  • Larger sprocket sizes to reduce the angle of flex.
  • Replacing sprockets when the chain is replaced.
  • Increasing the contact area between pins and bushings (multiple strands, larger chain size).
  • Increased hardness of the pins and the bushings.

Limiting the level of wear is one of the key maintenance tasks for chain in order to achieve better service life, and the proper lubrication of the chain plays a key role in maintaining a suitably designed chain drive.

Chain lubricant
Selecting oil with suitable viscosity for the application is important to ensure that it reaches the required surfaces within the chain. If the oil is too thick, it may not be able to reach the chains internal surfaces while an oil with too low a viscosity or lacking in performance may not provide sufficient wear protection.

SKF offers two ranges of oil to cover the requirements of most industrial chain applications for medium temperatures and high load/temperature, and a range of food grade chain oil range specifically developed for food and beverage applications where high temperature, high humidity and low temperatures are critical factors to consider in the selection of the correct oil. The whole range of food grade chain oil is NSF, H1 approved, therefore fit for the food and beverage industries.

Automatic lubrication
In situations where the chain needs frequent lubrication, or where the chain cannot be accessed safely or easily, a SKF SYSTEM 24 lubricators may be suitable to ensure the correct quantity of lubricant is delivered over a set time period and reduce oil consumption.

Conveying chains require continual lubrication to reduce high levels of friction that can result in chain wear, high energy consumption and unplanned production stops. In most plants, lubrication is applied manually – a task that requires the chains to continue running while production is stopped. In these cases, an SKF Oil Projection System can direct specific amounts of oil to only the pin locations to reduce unnecessary oil consumption, increase chain life and eliminate manual lubrication requirements.

SKF has documented success with oven conveyor chain lubrication where significant improvements in the operation were gained while reducing the risks of contamination and safety hazards.

Washdown and cleaning routines hard on motors

High pressure washing and strong cleaning agents do a good job keeping food and beverage processing equipment clean and hygienic. However, electricity and fluids do not get along very well. In particular washdown and cleaning routines can be very hard on motors and mechanical equipment. 

To hold up in these wet and demanding environments, John Brooks is the NZ distributor for a range of Tema Stainless Steel motors starting at 0.18KW and up through to 7.5KW. 

  • Tema Stainless Steel motors and gearboxes are designed and manufactured to operate in extreme conditions. Rated to IP67 they can withstand conditions with high ambient temperatures, high humidity, water and steam. 
  • All motors are supplied with a one-metre cable and are tested underwater as part of the standard testing. 
  • While stainless steel motors and gearboxes have a higher capital cost than traditionally used cast iron or aluminium units they can result in significant cost savings over their life cycle. 
  • Cast iron and aluminium units regularly fail when subjected to water, steam, chemical cleaning and outdoor use, especially in coastal areas. Add in the lost downtime to the replacement cost and stainless steel motors & gearboxes become a viable option with their long service life. 
  • Standard IEC metric frame with B5, B14 flanges. We can even supply Tema motors with flanges to suit SEW gearboxes making retrofitting your existing plant a simple procedure. 


All Tema motors have received CSA Approval and have been certified under USA Premium Efficiency and MEPS. 

Contact John Brooks’ sales staff to survey your motor and gearbox requirements and a recommendation as to the correct motor and gearbox for the job.

Norbar promises torque wrench calibration of the highest international standard

Let’s talk Torque Tools and the importance of regular service, repair and calibration. Whilst the standard recommendation for recalibration is every 12 months, there are always exceptions to the rule. For example, did you know, any wrench subject to an overload of 25% or more above the nominal maximum value should be recalibrated or risk inaccurate readings? Additionally those who fail to wind their torque wrench back to the lowest setting after every use risk spring memory loss (Hysteresis) which can negatively impact the tool’s performance and reliability.

Needless to say, the importance of having a sound management plan for torque wrench calibration cannot be underestimated. And who better to guide you on your way than Norbar Torque Tools,“the name you know”.
