Kenco Pipe Lifting Clamp

Kenco 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.

Which Kenco Barrier Lift do I Need?

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:

  1. The weight of the concrete barrier.
  2. 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.

Pavement removal bucket

The Kenco Slab Crab is a pavement removal bucket specifically engineered to expedite the removal of asphalt, concrete roadway and bridge decking. The Slab Crab’s unique design allows the operator to have complete control over the slab during the removal and loading process. This pavement removal bucket has a flat bottom which allows the operator to remove bridge decking in tight quarters. This concrete bucket with platform also allows for removal of road decking without disturbing the subbase.

The excavator operator is able to utilize a cantilever effect by tilting the Slab Crab which allows the slab to easily slide into the opening of this pavement removal bucket. The tapered opening makes it easy for the operator to acquire the slab and that same taper enables the Slab Crab to accommodate a great range of thicknesses. Once a slab is obtained, the operator can simply lay it on a flatbed, place in the back of a dump truck or stack it in a desired location. With contractors reporting that the Kenco Slab Crab increased productivity by 80% or better, it’s easy to see why this attachment should be in every company’s equipment arsenal.

Equipment used to lift pipe

Kenco offers a variety of pipe lifting equipment. Whether its concrete, ductile iron, pvc, corrugated, steel, terracotta or the like, Kenco has you covered. The Pipe Lift’s design allows each model to handle multiple pipe diameters. Not only does it safely lift but the operator can use it to push the pipe together. Since the Pipe Lift is automatic, there is no need to have a laborer in the ditch to disengage the lifter from the pipe once the joint is installed. Now that’s productivity.

Say you have pipe dimensions that fall outside our standard models. No worry, Kenco’s engineering department is second to none and will gladly design the lifter you need. From standard models starting with 4” pipe and the largest to date being a custom model for 142”, the possibilities are endless. Looking for another option to move pipe? How about the Kenco Pipe Hook. This pipe lifting attachment basically looks like an elongated “C” or its sometimes referred to as a hairpin. Regardless of the analogy, the design is simple and very effective. The operator slides the lower section into one end of the pipe and lifts. To make the process easier on the operator, our clever engineering staff has replaceable polyurethane pads on all “Pipe” contact areas. Each model of Pipe Lift has a very generous range. The smallest starting at 10” and the largest exceeding 60000 pounds. Safely increase productivity.

Seriously, what’s not to like here. Well, Kenco also offers a Super Lift, that when equipped with the correct bolt on tine set, can move just about anything. Rocks, logs, brush, barrier, block and you guessed it, Pipe. Each Super Lift model offers 3 pipe tine sets that cover just about anything. If not, let us know what you have, our engineering staff is up to the challenge. When it comes to equipment used to lift pipe, Kenco has you covered.

Common Barrier Wall Sizes in all 50 states

Divided highway systems utilize various methods to separate oncoming traffic lanes. The main method used is the placement of concrete barrier between opposing lanes. The individual Departments of Transportation in each state have specific standards for the size of highway barrier wall to be utilized in road construction projects. These protective concrete barrier wall systems are also widely known as jersey wall, jersey barrier, median barrier, medial barrier, or highway dividers. Below is a list of the wall sizes or concrete barrier dimensions normally being used in each state. Wall styles also vary by state.

How to Lift Precast Concrete

There are many construction companies that use a precast concrete system instead of pouring concrete on site. Production of precast concrete is used in a wide range of applications. These include architectural panels, free-standing walls, landscaping blocks, capstones, security walls, barriers, and pipe. Forming the precast concrete is completed on the ground level, which increases safety during the process. There is more control of the quality when the system can be completed in a precast plant rather than on a construction site. Also, the forms that are used in a precast plant can be reused many times over. This allows for lower cost of formwork when compared to that of casting at the job site.

Lifting, moving, and positioning the precast concrete systems can be quite cumbersome due to the weight, size, and shape of the object. Maneuvering a concrete pipe or panel to attach the lifting straps can be just as burdensome. Fortunately, there are other options available for contractors who prefer a more productive method when handling these materials, such as precast lifting devices or concrete panel lifters.

Kenco Corporation manufactures a wide range of precast lifting devices and attachments that are specific to the needs of the precast concrete worker. A Pipe Lift is used to grab, lift, and set concrete pipe directly into the trench. Jersey wall and other security barrier wall systems can be easily moved using the Kenco Barrier Lift. Our Kenco Multilift will move cut stone, block and slabs. These are just three of the precast lifting devices that Kenco has designed and engineered to enhance the capabilities of the precast contractor. Many of these actions can be accomplished with just one machine and one operator.

Kenco prides itself on making the job of contractors easier, more productive, and more cost effective with its panel lifting devices.

Factors to consider when choosing a lifting device

Frequently here at Kenco we are requested by a customer to provide a below the hook lifting device based solely on the dimensions (height, width, depth) of the object being lifted. While these parameters are likely the most pertinent, there are a host of other factors necessary to take into consideration in order for our engineers to provide the best solution.

Second only to dimensionality, is the material and structure of the object being lifted. If the object lacks the structural integrity to tolerate a pressure grip type of lift, it is necessary to determine what aspects of the object can be exploited to perform an alternate lift operation. Example: Does pipe need temporary bracing (stulling) to prevent crushing?

The amount of clearance available for the lifting operation is also an oft-overlooked factor. All aspects of the device’s intended use should be considered, including but not limited to:

– Distances between the object to be lifted and adjacent objects
– in storage
– in transit
– in staging
– at final placement
– allowable overhead clearances
– any changes in the orientation of the object that need to take place during the operation (such as from laying flat to standing upright position).

Another major factor in choosing the right Kenco lifting products for heavy objects is the type of equipment to be employed in both the handling and transit operations. Excavator attachments, forklift adapters, cranes, etc.. all have different operational characteristics that affect the handling of the object.

Setting Barrier Wall along the Pennsylvania Turnpike

Barrier wall is a common sight along the interstate highways, and the job of temporary placement to reroute traffic is a daily routine. In the spring of 2013, Strongstown B & K Enterprises was tasked with placing over 65,000 feet of barrier wall along the Pennsylvania Turnpike to separate the normal traffic flow around a scheduled resurfacing project.

A Hyundai 107 excavator was operated by Larry Prain to lift and position the 12 foot wall sections. Owen Covey assisted with guiding and interlocking the highway barrier walls into place. A Kenco KL30000NG Barrier Lift was used to handle the concrete. With this lifting attachment, each three ton wall could be grabbed right from the bed of the truck, set into position and then released automatically. It only took about 30 seconds for these two workers to complete the cycle. Each truck carried nine barrier walls which were being unloaded and set into place in less than 10 minutes. Prain said, ‘It makes it easy to set barrier.’ Covey went on to say, ‘The larger pads (on the NG series) really grab onto the wall. It saves us a lot of work and lets us get the job done much faster.’

Even at 30 seconds per cycle, that still calculated to more than 40 hours of work. The task required them to position over 5,400 twelve foot wall sections along eight miles of highway between the Blue Mountain and Carlisle exits.

Dallas/Fort Worth International Airport Renovation Project 2013

DFW International Airport is undergoing a massive seven year – $900 million dollar terminal renovation project. One of the tasks is to connect the airport to downtown Dallas via the DART rail, which is a light rail system. The DART will run between Northbound Service Road and Northbound International Parkway, and under Taxiway Yankee and Taxiway Zulu at the North end of the airport. Due to the type of work that needs to be accomplished, multiple lane closures are needed in various phases throughout the project

Phillips May Corporation of Dallas, Texas assisted with the project. In June and July 2013, development included lane closures of the 3 lane Northbound Service Road . Thirty-foot concrete traffic barriers (CTB) were delivered to the site on flat bed semi trucks. Using two Gehl telescopic handlers that were each fitted with a Kenco KL 9000 Barrier Lift, the wall segments were removed in unison from the truck beds.

The Kenco Barrier Lifts made a light task of what could have been heavy work. The CTB was picked up and placed in desired location, while flaggers were able to maintain one clear traffic lane during the operation.

One concern that was encountered was how to place and align the CTB under the overpasses of the Taxiways. The low height considerations posed a possibility of the machine damaging the overhead structure. To add to the challenge, the roadway converges to only two lanes at these points, and the airport still required that one lane remain open for traffic.

Once again, the Kenco Barrier Lift resolved the situation. A KL 30000 was chosen to handle the wall capacity and it was attached to a Volvo 320 excavator. Tyson Proovost operated the Volvo, maneuvering it along the future rail path and setting the CTB into position without disrupting the traffic flow.

Hoy Construction Uses KL-9000NG

Hoy’s Construction of Waynesburg, PA was tasked with setting up 12’ concrete barricade walls to separate a newly constructed walkway that ran parallel to a vehicular driveway.

Back at the company yard, boom truck operator Tim Williamson used a remote control to maneuver a Kenco Barrier Lift onto the necessary wall structures. The lifter had also been fitted with alignment legs, which allowed Tim the ability to position the device onto the wall without assistance.

Tim loaded the wall onto his truck, transported them to the nearby job site, and then placed the barrier into its desired position. A ground guide assisted Tim with interlocking the nine walls together. The entire process to set 108 feet of concrete barrier took less than 3 hours.
