Overheating is a common issue encountered within hydraulic equipment. And we know from experience that the overheating situation will shut down the exact wrong piece of your equipment at exactly the wrong time. We specialize in putting you, your business and your equipment back to work ASAP via rapid response deployment of our team of certified hydraulic repair technicians.

Whenever you encounter overheating issues within your hydraulic system, keep in mind that there are two ways to solve the problem. The first thing to do is to shut down the machinery and take a moment to think through the issue and eliminate the immediate threat of permanent damage to your equipment. You then must be able to restart the equipment with either a lower heat producing load or improved dissipation of heat. Maybe you can self-help this.

First thing to do is to inspect the fluid level of the reservoir. When it is low than the recommended level, refill it to reach the right level since hydraulic system eliminate heat through the reservoir. Make sure there are no accumulation of dirt that is blocking the airflow. Then, investigate the core of the heat exchanger and make sure there's no obstruction since its ability to remove the heat is reliant on the flow rate, hydraulic temperature and the cooling air or water that is flowing within the exchanger. You may also need to replace the cooling circuit parts if it is not working well.

Check how heat exchange perform by using an infrared thermometer as long as you know the actual flow rate of the hydraulic fluid in the exchanger. Check also the temperature of the oil that is coming in and out the exchanger and substitute the values applying a formula provided by a certified hydraulic company. A decreasing pressure will result to heat production. If internal leakage is present in any of the system parts, it will boost the heat load on the system, causing it to heat up excessively. There are multiple rationale behind this occurrence which includes a leaky cylinder draining a high-pressure fluid over its piston seal to a relief valve that was not properly adjusted.

Consequently, you need to change any of the heat generating parts that is worn out, and there are instances when a professional technician is required to figure out the component that is inflicting the issue. Regardless of the cause behind an overheating hydraulic system, it is imperative to turn it off immediately to get to the bottom of cause and mend it. Persisting to run it at inappropriate temperature is unsafe and will surely damage your equipment. It's important to be proactive when you notice an overheating system. Find the cause right away in order to address the problem.

Or, simply trust the professionals like use here at ETS. We’ll simplify your life, make sure your equipment is repaired in the shortest time possible, and put you and your equipment back in business.

ETS - Aerial Lift  - Boston, MA

Accidents are common with poorly maintained aerial lifts. Lift accidents are caused by faulty outrigger, wobbly guardrails, hydraulic leaks, defective brakes, and a host of other failures. Lift-related accident risk is mitigated dramatically via professional aerial lift routine maintenance service. Here are just a few documented accidents associated with poorly maintained lift equipment:

  • Tip-over incidents usually happen when the operator erroneously position the lift. It also takes place when you hit into an immovable object or the machine malfunctions. Ensure that you position the equipment on level ground far from divots, avoid other objects and make sure the equipment is working properly.
  • Fall accidents usually happen when a worker bend too much over the guardrail. Most of the time it is due to wrong distance estimation when reaching the next window or cable. To resolve this common incident, operator must be aware of the risk when operating an air lift at excessive heights. Always ascertain to move the aerial platform at the right position. Regular maintenance is required to ascertain your equipment can be properly maneuvered.
  • Electrocutions take place when operators run across an overhead cable or power line. Before turning on your engine, check your surrounding for any obstructions above you. Lower the lift when running beneath wires and avoid moving to hazardous areas. Assume all cable wires live.

Moreover, read the manual for your equipment’s horizontal and vertical reach limits. Stay within this limit for safety.

When it’s time for you and your business to bring your lift operations to a documented safe state, seek aerial lift testing services from the Boston-area professionals who’ve been doing this for decades now. Contact ETS Inspection and Testing Services, and let’s get it done!

ANSI Standard for Aerial Lift Safety Check

Joseph Coupal - Tuesday, March 31, 2020
ETS Inspection and Services, Boston, MA

The American National Standards Institute defines the mandatory aerial lift maintenance and repair standards that all lift equipment companies must adhere to. Companies must remain ANSI compliant not only for the purpose of ensuring safety operations but to prevent costly penalties and legal implications as well.

The A92.6 ANSI policy serves as a reference that influences manufacturing and design, rebuilding and reconditioning of all aerial equipment. The guidelines impact not only those who own the equipment, but certainly those who operate, inspect, maintain, and repair the lift equipment.

The annual and frequency inspection directives are listed in the guiding principles and the guidance and emphasis is clear that only certified technicians are to perform these activities. The personnel must be trained and certified in the care of the exact or models of similar function and capability. The inspection must take place at least every 90 days or after 150 hours.

Annual inspections must not exceed 13 months from the date it is previously checked. Plan the scheduled maintenance according to your operation hours and the type of service the aerial lift is employed. ETS can perform this routine upkeep for your machines. You can count on our expert technicians to service your equipment to the most stringent quality standards.

Contact ETS Inspection and Testing Services to help you comply with the regular maintenance of your fleet based on ANSI Standards.

Hot Stick Dielectric Testing Services

Joseph Coupal - Wednesday, February 12, 2020
ETS - Inspection and Testing, Boston, MA

Electrical linemen is by nature one of the most dangerous occupations. They regularly put their lives at risk as they service live lines daily. Ensuring that all safety tools such as hot sticks work at optimal performance is crucial. To ensure this, regular and recurring dielectric testing service must be accomplished to protect both staff and electrical resources.

Are your hot sticks scratched or do they have a dull finish? Such conditions indicate that the stick is possibly unable to repel water and introduces a dangerous environment. That device could conduct current. You might be conducting dangerous business operations without even knowing it.

ETS Inspection and Testing Service offers full testing and hot stick repair service to ensure hot line tools are safe to use and perform optimally. These tools include Hot Line Stick equipment, Pruners, Fuse Pullers, etc. They are dielectrically tested for defects and malfunctions. The sticks are temporarily removed from the service to send it for repair and refinishing. After it is restored, it is once again tested dielectrically to evaluate its performance as it needs to pass the standards.

Certified technicians will diagnose the issue, find out the root cause, perform a comprehensive maintenance check and provide the quote. Mechanical defects, scratches, and cracks are then repaired. Refinishing process is done to return the tool to its original condition. It will undergo another dielectric test to ensure it passes the safety and performance standard. The tools are continued to be cleaned and maintained when it is returned to the field.

Ways to Mitigate Hydraulic Cylinder Failure Risk

Joseph Coupal - Monday, January 27, 2020
ETS - Hydraulic Repair  - Boston, MA

If your business involves hydraulic equipment, cylinder repair and maintenance is likely a significant element of your operating budget. When that hydraulic equipment fails due to neglect, you can bet an unacceptably high hit will besiege your business due to operational downtime. Don’t let that happen.

A large percent of mechanical equipment failures is due to design failures. This means we can expect that there are hydraulic cylinders that are not exactly engineered for the purpose they're operating in. Although this doesn’t necessarily mean that hydraulic equipment failure is immanent, it certainly will shorten the expected life cycle.

So, here are things to look for and to conclude from your hydraulic cylinder inspections:

1. Rods That Are Bent or Deformed

This is usually caused by:

  • inadequate rod diameter or material strength
  • incorrect cylinder mounting arrangement
  • When cylinders are deformed or bent, deforming load is put on the rod-seal. This leads to leakage and premature seal failure.

2. Rod Finish

The cylinder rod's surface finish has an important impact on the rod seal's life. When it is to smooth, its seal life will be reduced because of scant lubrication. When it is too rough, it will increase contaminant infiltration and an intolerable leakage level beyond the rod seal may rise.

In order to extend cylinder service life, keep the cylinder rod's surface greased, early and often. For some applications, shroud or bellow installation can protect the rod surface and its seals from damage impact and contaminants, can provide comparable life extension advantages.

3. Inflated Cylinder Tubes

Insufficient wall thickness and material strength for the cylinder's operating pressure can result ballooning of the cylinder tube. When the tub balloons, the accurate tolerance between the piston seal and tube wall disappears, enabling high-pressure fluid to bypass the seal. This high velocity fluid can wear the seal and confined heating as a result of pressure drop across the piston decreases seal life. Premature failure of the piston seal can result.

4. Inappropriate Bearing Area

When bearing bands in the gland on the piston are inadequate to support the side thrust moved to the cylinder, the rod and piston seals are burdened with excessive load. This will result in deformed seals and premature failure.

Commonly Missed Items During Digger Derricks and Aerial Device Self-Safety Inspections

Joseph Coupal - Thursday, January 09, 2020
ETS Inspection and Services, Boston, MA

Annual inspection of Digger Derricks and Aerial Devices are essential acts not only to adhere to OSHA or ANSI requirements but to ensure the equipment is safe to use. A thorough inspection must be applied to all system components of the device. Although user manuals specify the components to be checked, a certified technician with adequate training, knowledge, and competitive experience is essential to ensure a comprehensive inspection.

If you're an owner and you choose to perform you own annual inspections, just know that you are likely to miss or overlook critical items that professional inspectors are trained to focus upon. Here is some list of most frequently overlooked items:

Overlooking Safety/Operational Labels

Operational and Safety labels provide significant details to users. The decals attached to the equipment might be damaged or removed from power washing over time. You are likely to miss a component if the decals are no longer in place. Hand signal charts must not be omitted from digger derricks. They provide an important function in the communication between operator and ground personnel, especially in a loud setting. Potential injury or damage in equipment is imminent if there's a failure to convey directions clearly.

Poorly Maintained Hydraulic Oil Levels and Hydraulic Filters Are Not Replaced

Hydraulic oil levels must be maintained based on the manufacturer's recommendation in order for the equipment to run seamlessly. If it reaches a low level but left unattended, it could lead to untimely costly repairs. It could initially cost you $2,000 repair for burning up one pump. Aside from that, you should also consider the deficit due to the equipment being removed from service.

Meanwhile, you should not check the fill levels when the outriggers are extended for it can concur to overfilling. When the system is overfilled, the space is no longer enough for expansion. This can add up to oil leakage. Moreover, a dirty oil filter can expedite the deterioration of the key components including pumps, hydraulic valves, cylinders, and hoses. This is because the filter is no longer efficient in trapping debris and contaminants prevalent in the fluid.

Defective Winch Rope

The winch rope should also be unwound and checked by hand at the yearly inspection. If you notice cuts or feel a bulge, this indicates an internal rope damage which is an outcome of shock loading or kinking. This means the rope must be replaced. Rope manufacturers provide more scrutiny and replacement conditions.

Torqued Rotation Bearing Bolts

This is an important item in the inspection list that should not be missed. Two personnel must do the checking so one may rotate the bearing while the other one inspects the bolt torque. Proper bolt torque and greasing must be done. Otherwise, it could result in failure of bearing bolt because the rest of the fasteners are overloaded. Repairs related to bearing failure could cost you up to $10,000.

Bearing Deflection/Backlash Has Too Much Allowance

Inspecting the allowance in the rotation bearing takes a while to master and requires clear insight on how to measure it. Too much allowance could indicate rotation bearing is worn and requires replacement. Furthermore, it may also hint that the boom has been shock loaded.

Leveling Chain Is Too Loose

Aerial devices' leveling chain must have precise amounts of preload. Potential wear and tear can increase when there's too much or too little tension. Inspecting the leveling tension needs removing off the boom lid. When the chain is not kept within tolerance, it may impact the self-leveling of the bucket when the booms motion through their range of motion.

Bucket and Liner Wear and Tear

The structural integrity of the bucket is damaged when there are cracks and distortions noted. A damaged liner can add up to the diminishing dielectric strength. Most of the time, inspectors fail to take off the liner when checking the bucket. Tools can drop and damage the liner, even the bucket. So make sure to check inside and outside the bucket and include underneath it.

Although carrying out the task on your own may appear as an affordable option, it is highly recommended to seek certified technicians who are experts in this field. If you are looking for a certified company who can conduct dielectric testing and inspection, contact ETS Inspection and Testing Services.
