Barrier walls come in a vast array of shapes and sizes. There are many different concrete barrier walls in use today. Some states share the same barrier wall design; other states use several different designs. Choosing the right concrete barrier lifter or jersey barrier picker is not difficult. Here are a few parameters that you need to know before choosing the correct Kenco Barrier Lift:
- The weight of the concrete barrier.
- The dimension across the top. To get this dimension, extend a straight edge up each side past the top of the wall (this will give the most accurate measurement, as most barrier walls have a small radius on the top corners), then measure across the top to each straight edge. You can use the print that is available from the manufacturer of the precast concrete barrier wall as well.
If there is any doubt to your particular barrier wall, send a copy of the print to sales@kenco.com and we will make the determination for you.
How do I determine the specifications of my current Kenco barrier lifter?
Kenco Barrier Lifters have a Serial Tag with information that includes the serial number, weight capacity and dimensional range. If for some reason the serial tag becomes unreadable, destroyed or is missing, the serial number is also stamped into the lift bail or a crossing member on the top surface of the barrier lifter, which we can use to track needed information. Feel free to call with any questions regarding the use of our barrier lifter.
What other considerations should be taken into account?
Remember, just because the lifter fits over the wall doesn’t mean it will lift the wall safely. It is up to the end user or operator to verify the correct sizing. For instance, if you were to use our old model KL9000 with a 6” to 9” range on a precast concrete barrier wall that weighed 7,200 pounds and correctly measured to 9-1/4”. The lifter may fit over the barrier and have enough capacity, but the problem is that the automatic actuator may not stroke far enough to rotate the correct amount to let it release. The barrier lifter may incorrectly pick up the concrete barrier wall, because the pads will rotate and cam them into the barrier. This will cause damage to the barrier lifter and it could possibly drop the barrier wall, which may seriously injure site personnel. In this case, the old style KL9000 with a 9” to 12” range was recommended.
Since 2014, all standard models of the barrier lift are manufactured with a 6 to 12 inch grip range, wider pads to increase total surface contact, a fuller pad angle rotation to accurately contour to the wall slope, and integrated handles on both sides of the lifter. The older models are now obsolete, though it may take some time, because some companies are still using Kenco jersey barrier pickers that were purchased over twenty years ago.
Patching Roadways with the Kenco Slab Crab
/in BlogIn a perfect world a roadway would never need repair. It would withstand all elements including mother nature and the wrath of daily vehicular slaughter. However, a short drive down nearly any interstate will prove this is simply not the case. Orange cones and construction sites are a common sight and rightfully so. To put it in perspective, the Pennsylvania Turnpike feels the impact of at least 500,000 vehicles per day. That’s over 3.5 million vehicles per week! With today’s heavier freight loads and the increasing number of drivers on the road, imagine the wear and tear our roadway system sees every year.
With this type of abuse, comes the need for repairs with the safety of all travelers being the utmost concern. A very common practice to fix large cracks, holes, or structurally failing roadways is to patch them. Patching first requires the removal of the concrete surface down to the subbase. The damaged section of concrete will first be saw cut into a manageable size. Then a hammer is often used to break apart these slabs into smaller pieces. After switching out machines or construction attachments, a bucket removes the rubble. This process requires strenuous hours and additional time to repair the disturbed subbase misplaced by the digging action of the bucket.
So the question is – could there be a concrete removal machine to keep workers safe, cut down time, and keep the subbase intact? There most certainly is! And the great news is you may already have this tool in your toolbox. What is it? The Kenco Slab Crab of course! You didn’t think this excavator attachment was just for bridge deck removal, did you?
When it comes to assisting in concrete removal for patching of roadways, sidewalks, or even pathways, the Kenco Slab Crab shines in its multi-purpose glory. Just like a typical attachment, it is sized specifically for your machine or quick attach system. However, what makes it entirely different is heavy duty ribbing making it far more rugged than any conventional bucket. The elongated base frame reduces the digging effect on the subbase and allows for the slab to be loaded in a single horizontal movement. The sides are cut deep towards the back of the throat assuring the slab’s width will be fully supported in a cantilever fashion. The bucket teeth of the Kenco slab crab can also be used to provide optimal force to pry the slab up and break it loose if need be. And best of all, the slabs can be loaded onto a truck for easy removal. No rubble or broken concrete to fuss with.

Introducing the Pipe Hook with Box Culvert Wings
/in BlogThe Kenco Pipe Hook was originally designed specifically for the lifting, moving, and setting of concrete pipe and has since become the leader in the pipe-handling market. With such great success, comes a new “addition” that aims to add more versatility for higher productivity on the jobsite.
Currently both round and square box culverts are lifted by connecting and disconnecting a special rigging system or bridle to perform every lift and release sequence. This takes unnecessary time and in the current fast-paced construction field, time means money equating to money lost.
What if there were an easier way? What if one lift could do more than just one job? Now, there is just that. Meet the Kenco Pipe Hook with detachable box concrete culvert pipe lifter wings.
These box culvert wings are designed specifically for the job at hand. They are attached via a keyway system to each side of the hook’s main body. The mechanics of the lift process remain the same as for lifting RCP. The operator approaches the culvert from the side to insert the hook. The wings will help to stabilize and balance the culvert box, assuring that no tilting or twisting occurs during the lift process. Each lift happens in a single smooth motion with the set and release step occurring just as quickly. It’s a safe and efficient way to increase your productivity while saving you from purchasing multiple lifts to do each job individually.
There is no doubt that this ‘dual purpose’ Pipe Hook is going to become the next best “tool in your toolbox”. And if you already have a Pipe Hook, contact us about a weld-on kit so you too can take advantage of this new design improvement. This can be the best investment you’ve made in a long time to make the job go more smoothly.

Crazy Horse Memorial meets the Kenco RockLift
/in Use CasesCrazy Horse, one of the most notable Native American war leaders in history, could have never imagined how he would someday be memorialized. A man who had been characterized as being shy or aloof now towers over 500 feet above the Black Hills in South Dakota. The Crazy Horse Memorial finished product will surpass Mount Rushmore as having the largest sculpture of the human head measuring a whopping 87 feet tall! It will also be the largest sculpture in the world upon completion but this project hasn’t come without delays.
For years Crazy Horse sat untouched, waiting for funding to finish the project. But with every few steps back, comes several more forward, and once again the mountain is buzzing with excavators and workers. You can imagine the absolute honor and privilege it was when Kenco was contacted for help. They needed a way to move rock atop the mountain from the place it has been cut to a safe location away from the job site, with the safety of their workers being at the utmost concern. Kenco of course, had a solution and within a short time period, our Rocklift was put into action. Images and videos of the site show the nearly completed face of Crazy Horse almost casting a watchful eye as each rock is meticulously chipped away and carried with ease. Workers are safe and the mountain has been awoken once again.
Not every Kenco Rocklift will be as lucky to be a part of such a project, but every Rocklift will perform like the last – safely and consistently. No matter the size of the project, there truly is a lift for it and this project is a true testament to that.

Kenco Pipe Lifting Clamp
/in Use CasesKenco offers an easy, safe and cost-effective way to move RCP, ductile iron, PVC or steel pipe. The Pipe Lift will grab and release pipe from inside the cab. It will double production of pipe installation versus methods using slings and cables.
No additional hydraulics are required to put the Pipe Lift into operation – it hooks up with just a lifting strap and shackle. The unique design of this lifter machine for construction allows each model to grip a wide range of pipe sizes. Centering the lifter on the pipe is not necessary and its narrow profile makes removal from tight trenches easy.
This pipe holder clamp machine operator simply sets the lifter down onto the pipe. This causes it to grip onto the pipe, and it will not release until it has been set down firmly into position.
The PIPE LIFT is available in sizes to accommodate all types of pipe from 7.62 cm OD to 3,855.5 cm OD. Model capacities are available from 680.38 kg to 3,855.53 kg.
