DSC Dredge’s custom dredging solutions derive from a long history of working with customers to discover every aspect of their application needs – often resulting in Custom Class dredges that are entirely unique from DSC’s other dredge lines. The company explores all of the details of each project, such as the materials being dredged, depths, length of flow run, discharge point elevation, engine and pump preference, portability requirements, hull depth requirements, excavation power needs, access to power grids – and any other relevant information. DSC, which is based in Reserve, La., typically builds two to three fully customized dredges each year.
DSC has for example manufactured the Western Hemisphere’s deepest sand mining dredge, with a dredging depth capability of 200 ft. This dredge was equipped with digging jets, rather than a cutter head, because the sand in the application is free flowing, and high excavation forces are not required to mine the deposit. The company also just completed an aggregate dredge earlier this year that will dredge down to 155 ft.

JLG Industries, Inc., an Oshkosh Corp. company, launched two new high-capacity telehandlers at the show. These new machines will be available to North and Latin America lb. of lift capacity. “Not only are these machines the first JLG telehandlers in the high-capacity category, but they are also the first telehandlers in North America with SmartLoad Technology,” said John Boehme, JLG Industries product manager, telehandlers. “SmartLoad is an advanced bundle of three integrated technologies that work together to deliver a greater level of operator confidence. It will be offered as optional equipment on the 1644 and 1732 telehandlers.”
The first component of the SmartLoad Technology bundle is attachment recognition, which allows a telehandler to identify an attachment and display the appropriate load chart to the operator. The second, a load management information system (LMIS), graphically depicts the location of the load within the load chart, provides the operator with an indication of compliance and prevents the operator from violating the boundaries of the chart; and the third, a load stability indicator (LSI), works in conjunction with the LMIS to limit operation when a load becomes non-compliant.
“Armed with the real-time load data this package provides, operators will work with increased confidence, while fleet owners avoid the costly repairs that may result from overloading a machine,” Boehme said.
Additionally, the JLG 1644 and 1732 are among the first equipped with JLG’s precision gravity lowering system. Equipped with this system, the telehandlers rely on hydraulic power to raise the boom, but use gravity to lower it, providing the operator with better, more precise control. According to Boehme, JLG plans to incorporate this new technology throughout its entire line of JLG telehandlers later this year.

Regal Beloit Corp.
Regal Beloit Corp. announced it has launched the Time Saving axial groove in bore feature to the SealMaster Large Bore Performance Gold Line Mounted Ball Bearing.
The new feature is available in both medium 2-7/16-in. and up and standard 2-11/16-in. and up shaft sizes, and the Time Saving axial groove in the inner ring bore allows for easier bearing removal. This design provides clearance from the burr created by the setscrew used to lock the bearing to the shaft, which makes removal difficult and can cause damage to the shaft during removal. This feature has no impact to ball path roundness, load and speed rating, strength or bearing performance.
“Through years of customer discussions, on-site installation and removal observations, it was evident that the burr created by the setscrew had a significant impact on the time required to remove mounted bearings,” said Ian Rubin, director of marketing, bearings, at Regal Beloit Corp. “With time being a very valuable commodity in plant operation, we recognized the importance of developing a solution that reduces downtime and lost production, in turn potentially saving thousands of dollars.”
In addition to the time and related costs saved during bearing removal, the design also reduces damage to the shaft. A reduction in damage to the shaft not only then reduces the cost associated with repairing the shaft before reuse, it can eliminate the cost of having to replace the shaft.

Terramac showcased three unique crawler carrier models, the RT9, RT14 and RT14R. all of which deliver superior performance and versatility to tackle the toughest jobs. These units are well-equipped to provide operators with maximum efficiency and easy maintenance in a wide variety of applications.
Terramac’s mid-size RT9 and larger RT14 straight frame units are well known by contractors for their customization options and key features. No matter what the application – from general construction or aggregates to pipeline or utility – Terramac’s crawler carriers can help tackle any jobsite challenge that comes along. Terramac customizes electrical power sources and frame adjustments on these models to suit any configuration.
When configured with the standard dump bed, Terramac’s straight frame units are ideal for carrying material to hard-to-reach jobsites. And with the heavy duty rock-dump bed, the units haul the heaviest materials – including dirt, mud and rocks. The larger RT14 can also be outfitted with a flatbed, making mat hauling easier on the right of way.
For environmentally sensitive jobs, the RT9 and RT14 crawler carriers can be equipped with specialized restoration equipment, such as hydroseeders, allowing for environmental crews to spray seed mix for erosion control with minimal disturbance to the ground. Other attachment options include bark blowers and straw blowers.
For mining applications, both RT9 and RT14 units can be configured with a water tank and hydraulic crane unit to handle drill sections. Power for the crane comes from the gear pump powering the dump bed. In addition, both models can be mounted with a spray boom for dust control on tailings ponds.
The Terramac straight frame models are capable of conquering the toughest pipeline jobs. The RT9 and RT14 can be outfitted with a variety of industry tools and equipment for pipeline applications including tack welders, pipe heating units, personnel carriers and vacuum excavation units.
Equipped with a digger derrick, the RT9 tackles a myriad of utility tasks that include digging holes, lifting/setting poles, turning screw anchors and setting transformers. The RT9 also accommodates boom tip configurations, multiple sized augers for different jobsite applications and outriggers for extra stabilization.
Built with a rugged upper frame that rotates a full 360 degrees, the Terramac RT14R crawler carrier hauls and dumps material at any position, even while driving. This unique rotational functionality allows the RT14R to offload materials faster than a standard straight frame unit as its tracks don’t need to be counter rotated to drive another direction.
The RT14R’s ability to dump without tearing up the surrounding ground also minimizes environmental damage and land restoration costs. Low ground pressure and rotating functionality make the RT14R ideal for work in confined spaces and environmentally sensitive areas, such as: railroad track right of way access, rivers and levees, general earthmoving, site prep, mining and utility jobsites.
Thunder Creek Equipment
Thunder Creek Equipment gave attendees a look at the industry’s first combination diesel and diesel exhaust fluid (DEF) transfer tank for pickup trucks. This exclusive combo tank provides 100 gal. of diesel and 18 gal. of DEF capacity that fits seamlessly into the bed of pickup trucks (half-ton and larger – including goosenecks and fifth wheels) with both pumping systems concealed within its structure – no elements protrude from the tank. The sleek design ensures excellent rear visibility by taking up no more than half of the rear window.
“We know that many equipment owners are still in the early stages of determining the best way to handle DEF in the field,” said Luke Van Wyk, national sales manager and owner, Thunder Creek Equipment. “This combination tank – which takes up a similar footprint as today’s pickup truck tanks – provides owners with an efficient and contained way of transporting both diesel and DEF out to the field in a design they are familiar with.”
The combo tank features a 100-gal. steel diesel tank, and an 18-gal. polyurethane DEF tank that can be substituted with a tank and pumping system for engine or hydraulic oil. Both fill nozzles (available in automatic or manual) are located on the driver side of the truck and extend out 10 ft. from the tank.
An optional thermostatically controlled DEF heating system is available for use in northern climates that ensures that the temperature of the DEF tank, pumps and hoses doesn’t dip below 25 F. The 12V Webasto heating system is entirely self-contained and runs off diesel from the tank.
Diesel is pumped at 15 gal.-per-minute (GPM) via an industrial-grade 12V pump, while DEF is pumped at up to 10 GPM. Thunder Creek’s proprietary 2-in-1 DEF pumping solution, which pumps DEF in and out of the tank via a closed system to ensure fluid quality, is also available as an option.
The entire transfer tank and all of its components are concealed within a lockable, weather-sealed enclosure and comes with diamond plate aluminum doors as an option.
