Mar 12, 19 • Cranes • Comments Off on What is the Difference Between Articulating Boom and a Telescopic Boom?
There are two primary types of boom lifts on the market today: articulating and boom. Both are valuable additions to a work site that make it easier to get the job done. However, there are differences between the two types of boom lifts that make them better suited for specific uses. If you’re trying to decide which one is best for your work site, here’s what you need to know.
When they are malfunctioning, it not only leads to frustration on your part, but it also can lead to downtime and lost business opportunities. If you regularly work with industrial equipment like cranes who need regular service and repair on parts such as torque converters, here are some important signs that your torque converter is going to need service real soon.
Traditional disk brakes usually experience very high temperatures which can have severely detrimental effects on their performance. To lower these temperatures, the use of fluids such as water is imperative to eliminate much of this friction-generated heat.
What are Water-Cooled Brake Systems?
A water-cooled brake disc consists of central and stationary aluminum cooling plate that has an internal chamber which circulates the water coolant. It also has a series of cast iron sectors which are mounted on opposite sides of the disc plate. This is to allow for contact from the friction material carried by discs on the shaft to be slowed down. The cooling plate and iron cast sectors are usually divided by thermally insulative layers such as thin air gaps.
Knowing the symptoms of a failing torque converter can make diagnosing problems with a machine much easier.
Despite the excellent capabilities and reliability of the torque converters we provide, problems do arise from time to time—especially considering the extraordinary torque converter performance your extraordinary projects require. Here’s a guide of the most common issues that could arise with your heavy machinery torque converter, as well as a list of signs and symptoms to look out for.
3 common torque converter problems:
1. No Power from the Converter
You know the feeling—you ask for power and get very little of it. A problematic torque converter can play a big part in this because it plays a vital role in converting horsepower to torque. To get proper power from the torque converter, you need to allow enough time for converter pressure to form. If it doesn’t, you won’t get the power you need.
When the torque converter fails, it can cause the transmission to receive too much or too little fluid, which in turn causes the transmission gears to slip. This will result in a loss of power for the machine. If you notice the machine doesn’t have the amount of power it should have, it could be the torque converter. In cars, a sign of this would be a loss of fuel economy. Also, be sure to rule out low or dirty fluid. It may be the system just needs a fluid replacement.
2. Surging and Lagging
Surging is the flip side of the power-loss coin. If your machine “surges” or “lags” during operation—in other words, if it can’t seem to maintain a constant speed, power, or lift—it might be a torque converter problem due to erratic converter fluid pressure or flow.
A failing torque converter with high fluid pressure can cause more power to be transmitted than normal from time to time. This will cause the machine’s power to “surge” unpredictably. It may be a rare incident, or the engine might seem to be speeding up and slowing down in a cycle. The torque converter may be the culprit if the engine is functioning normally.
3. Power Loss due to Clutch Slippage
You’ll notice this when, especially after heavy acceleration, the clutch tends to slip. It will feel just like the converter is losing power while all along, the engine is making power, but the master clutch assembly is not transferring power to the torque converter.
A simple clutch adjustment and you can be up and running in no time. If this condition goes untreated for too long, excessive damage will occur to your master clutch assembly requiring removal and replacement. The key to saving money is maintaining your equipment and fixing problems quickly before they grow into bigger problems.
Signs and Symptoms to Watch Out For
Diagnosing torque converter problems can be tricky because the symptoms often look like a problem with the transmission, but that’s not always the case.
Let’s take a look at a few symptoms that you can spot to detect when something has gone wrong. After all, spot the torque converter problems early on, and they’ll be much easier (and cheaper) to fix.
Symptom 1: Shuddering
A mechanical failure in a torque converter can cause serious shuddering. In a car, the shuddering can be severe enough that it feels like driving on a gravel road. The shuddering is caused by a misalignment inside the converter, and it can be intermittent. If you notice shuddering when a machine is operating, have the torque converter and transmission checked out immediately, as it can be a sign of an imminent failure.
Symptom 2: Strange Noises
Clicking, grinding, or revving noises coming from the torque converter are a sign of a mechanical problem. Have it serviced immediately.
Symptom 3: Contaminated Transmission Fluid
If the torque converters’ moving parts come into contact and grind against each other, the result will be contamination of the transmission fluid. Chances are, this problem will lead to other symptoms like noises and shuddering, but it may be subtle enough that it’s not detected until the fluid is checked.
Symptom 4: Overheating
A transmission that’s overheating can be caused by a failing torque converter. If the converter’s seals have gone bad, the fluid used to transmit power from the engine to the transmission could be leaking. A drop in fluid pressure will cause the transmission to overheat. Of course, the leak could be somewhere else, so check for a fluid leak before replacing the torque converter.
Symptom 5: Slow engagement
With a ruined torque converter, the transmission will take longer than usual to engage the engine. This slow engagement results in higher stall speeds. Check you engine’s stall speed specifications, then perform a stall speed test based on the specifications listed, in order to diagnose for any torque converter issues.
How to fix your torque converter problems
Using machinery with a bad torque converter is extremely dangerous, and doing so exacerbates the symptoms listed above. Once you have identified that the torque converter is the problem, you will need to get it replaced by professionals. This particular piece of the machinery is delicate and complicated. Therefore, it should not be fixed by the average person. Otherwise, more damage to the equipment could occur.
Take a second from time to time to inspect the torque converter for visible problems like fluid levels, pressures and clutch adjustment to catch potential problems before they exist, but know that we’re here for you when more serious problems arise.

Dec 5, 17 • News, Power Take Offs • Comments Off on What Is a Power Take Off, What Does It Do, and Why It’s Important
What is a power take off? Power take-off (PTO) transfers the mechanical power of the engine over to another piece of the equipment. This allows for the power to move throughout the equipment to transmit energy even if it doesn’t have a motor or engine itself.
How the PTO Works
The rotating power from turning gets turned into what is known as hydraulic power. This has also become known as fluid power, and it gets controlled through a pressurized system. The rotating motion will cause a buildup of pressure in the crankshaft, and the power can be used for a variety of different purposes as it builds up.
Some of the uses that you might turn it to include:
Greater engine efficiency
Controls the hydraulics for raising or lowering dump truck bed
Used for towing vehicles
Runs the water pump to spray through the hose
You will see that PTO has been used for a variety of different applications like harvesters, wood chippers, hay balers, water pumps and carpet cleaners.
The Types of PTO’s
In years past, we saw Power Take-Offs operate from a belt drive, pneumatics like bleed air and drive shaft attachments. In most circumstances today, how PTO works is with a geared transmission. However, you still have three common PTO methods available on the mobile machine market:
Engine crankshaft-driven style
Truck transmission style
The crankshaft-driven method usually gets used for hydraulic pumps mounted to the front of your truck. For example, you might use it for a cement mixer. The small shaft will have a U-jointed design and attach to the yoke coupler for turning the pump. Normally, you don’t hear this configuration referred to as a PTO, but it still technically classifies as one.
How does a PTO work? You can trace the tractor PTO back almost as far as tractors themselves from when most of the PTOs drove with a transmission, located near the back part of the tractor. This form of PTO will only engage when you power up the transmission clutch. In fact, the mechanism couples with the transmission so that when you depress the clutch, the PTO doesn’t run.
Truck PTO Transmission Style
Smaller trucks use the PTO to drive the hydraulic pump for a hoist or winch. Meanwhile, large trucks might employ a PTO for a variety of purposes, but hydraulic pumps are the most common, and they get used to load and unload the different types of cargo. For a larger transmission, you might have two to three of these to help with the provision of every transmission. Let the normal clutch out to get the output shaft to spin.
Applications of the PTO
Whenever the equipment doesn’t have its own engine, you will see this used. For example, you will often see PTOs used in commercial vehicles and farming equipment. In fact, the innovation of the PTO came mostly from the ingenuity of farmers. A tractor engine serves as the PTO to operate a jackhammer or other equipment.
Some of the other applications where you see a PTO includes:
What Does a PTO Do?
When you ask, “What does a PTO do?” you can sum up the action where it converts rotary power over into hydraulic power. Once converted into hydraulic power, it runs the hydraulic hookups like oscillating power mowers, cotton pickers, backhoes, fire engine pumps and dump trucks. The access happens most often through a mechanical, electrical or hydraulic pump, and the motor converts the force back into a mechanical force or a rotary force, depending on the need.
What is a power take off? The internal mechanisms of the system use the engine to power up separate parts of the machine. This makes for better convenience, more efficiency and a cheaper option than installing another motor. Anyone who uses industrial equipment every day will understand the value of this technology, even when they can’t answer the question of, “how does a PTO work?” If you’re looking for a power take off, we offer top quality PTO replacement parts. Contact us today to find out how we can help you!
Why Are Power Take Offs (PTO) Important?
The PTO takes energy that would’ve been wasted otherwise and transfers it over to another source. This is what helps it to perform a variety of functions that are entirely necessary. For example, towing wouldn’t be possible at the weight amount that it is without having power take off. That’s why having this installed in your machinery matters because of how much it can help you with different applications.
A hydraulic pump uses hydraulic power pump drives (PPDs) engineered for agricultural markets, as well as construction, forestry, petroleum, and marine industries. The hydraulic pump is a mechanical device that produces hydraulic energy from mechanical power. It generates flow with sufficient power, which will allow it to overcome pressure from the load.
