Topcon MC-Max offers an affordable, portable solution for mixed fleets

Machine data is more useful when it can be pulled together for analysis and viewed across a mixed-fleet worksite, and that’s the thinking behind Topcon’s new MC-Max platform.

Designed to adapt to contractors’ machine control and data integration needs as their fleets and workflows expand, the new Topcon MC-Max increases processing power, speed, accuracy, reliability in GPS/GNSS guided earthmoving and sitework, says the company.

Backed by Sitelink3D, MC-Max can be installed on a full range of dozers and excavators. The MC-Max is based on Topcon’s MC-X platform and offers flexible mounting solutions, as well as optional automatic blade and bucket control. The system also provides a full range of positioning technologies from slope control to laser, multi-constellation GNSS*, robotic total station and Millimeter GPS systems. With it, you get a live view of machine positions, activities and onsite progress. MC-Max is also compatible with a wide range of jobsite communication systems.

“With MC-Max, we’ve created a solution that is flexible and can continue to grow as a contractor’s needs and capabilities expand,” says Jamie Williamson, executive vice president, Topcon Positioning Group. “This new solution provides improved scalability and precision in the field and offers business owners real-time data integration, connectivity and resource management capabilities across their entire workflow.”

Topcon positions the MC-X Platform as an easy-to-use and affordable machine control solution. The platform provides seamless data with mixed fleets by interacting with multiple versions of 3D-MC. Sitelink3D is the company’s real-time, cloud-based data management system.

*Multi-constellation GNSS systems are machine control platforms that receive positioning signals from multiple satellites in orbit around the earth. The more satellites a system can “see” the better the data and the less likely a system will lose the satellite connection.

Cat intros 8-foot pavers for smaller, tighter jobs

To the contractors asking for a compact paver from Caterpillar: your wish has been granted.

Cat has filled the gap in its product offering with a new line of 8-foot size-class paver and screed combinations. The AP400, AP455, AP500 and AP555 asphalt pavers, along with the SE47 V and SE47 FM asphalt screeds, are designed for small, tight jobs such as narrow streets, driveways and small parking lots.

“Compact pavers and screeds offer opportunity to both large and small contractors,” says Cat sales consultant Jon Anderson. “For large contractors doing pullouts and shoulders, this is the perfect machine for that at a lower cost point. For smaller customers, it gives them the opportunity to move up and do some bigger jobs that they’ve always wanted to bid on but didn’t feel they had the equipment for.”

The SE47 V screed can be extended to any width between 8 and 15 feet 6 inches, with a maximum width of 20 feet. The SE47 FM screed offers a standard paving range between 8 feet and 15 feet 6 inches, with a maximum width of 20 feet 6 inches. Both screeds offer paving depths up to 10 inches.

“One of the hardest things is to do a job where the paver is too big and you’ve got to do everything at the very minimum width,” says Anderson. “It’s a real challenge, so this provides new opportunities.”

Easy to load or road

When moving between multiple jobs per day, equipment must be easy to haul. Cat says these 13- to 15-ton size-class machines don’t require special permits for transport and have convenient tie-down locations.  

With a length of less than 18 feet 6 inches and width of 8 feet 6 inches, the pavers easily fit on trailers and can be hauled with other equipment. In addition, the front-loading angle of 17 degrees and high bumper clearance simplifies loading without the need for additional blocking material.

Roading it rather than loading it? Anderson says the versatile undercarriage design delivers “excellent traction and speed for traveling to the next starting point.”

The Cat Mobil-trac undercarriage design used on the AP455 and AP555 features a unique four-bogie system with self-tensioning accumulators and center guide blocks. This helps prevent slippage and reduce wear, while the oscillating bogie wheels help deliver smooth transitions when exiting the cut over transverse joints of mill and fill applications.

A simple wheel undercarriage design is also available with sand-rib or radial drive tire options. The AP400 can be equipped with a front-wheel assist option, while the AP500 can be equipped with front-wheel assist or the all-wheel drive option for increased performance on soft base materials or when pushing heavy loads.

Simple, intuitive operation

Simplified menu structures offer touch-screen activation from the main screen.Equipment WorldStandardized controls across the Cat paving product line make it easier to move crew members between machines and train new hires.

“We have some new, simplified menu structures that make it easier to make changes and a single-touch activation for the feeder system,” says Anderson. “The new display has fantastic visibility even in bright sunlight.”

The screed heat, fumes ventilation, vibration settings and the washdown system are all accessible with the touch of a button from the main menu, helping operators start faster and increase productivity.

Versatile new screeds

Screeds with rear or front-mounted extenders enable contractors to match their application needs. The SE47 V is a rear-mounted screed, meaning hydraulic extenders are behind the main screed. This design enables material to naturally flow out to the end-gates for smooth, stable performance.

The SE47 V and SE47 FM offer efficient heating and simple adjustments.Equipment WorldRear-mount screeds are typically chosen by 25 percent of customers, and Pennsylvania-based Schlouch Incorporated is one of them. “Over the years our employees have consistently given us the feedback that the rear-mount screed works the best for them,” says Glen Powell, Schlouch paving department coordinator and project manager.

The crew at Schlouch has been field testing the AP455 with the SE47 V for the past year. Here are some of the reasons why they prefer the rear-mount screed:

Full catwalk: “It has a full catwalk. When you run the extensions out, the catwalk extends with it so they can continue to walk out to the end of the extension,” says Powell. This allows for excellent visibility when paving in neighborhoods around stormwater inlets. Durability, rigidity and weight: The setup is also well-suited for high-tolerance applications such as sport courts. “The added weight of the screed behind the machine gives us a nicer mat coming out from behind, gives us a little better compaction right behind the screed and allows us to achieve good results,” says Powell.  

A front-mounted system may be a better option for contractors who frequently need to maneuver around obstacles like curbs and light poles. The SE47 FM is equipped with hydraulic extenders in front of the main screed and offers a smaller footprint that reduces handwork at the start of the paving pass. When the paving width is reduced, material is quickly drawn back into the auger chamber.

For contractors requiring wider paving capability, optional extension packages, as well as berm attachments, are available for the SE 47 FM.

Fuel-efficient power

Cat designed the new pavers with an eco-mode feature that pairs with automatic speed control to reduce fuel consumption. In most conditions, the engine can operate at a lower rpm and still deliver the required power to meet performance requirements. If needed, the engine will automatically adjust to a higher engine speed if certain load conditions are met.

The AP400 and AP455 have a 120-horsepower Cat C3.6 engine, and the AP500 and AP555 run on a 148-horsepower Cat C4.4 engine. Both engines meet Tier 4 Final emissions standards.

Enhanced visibility

Operators will immediately appreciate the enhanced visibility into the hopper and unrestricted forward view on these compact machines. The exhaust stack has been integrated into the new hood design and does not extend upward as it does on other Cat paver models. The pavers’ small footprint delivers excellent mobility in tight spaces and low-clearance applications.

“A few of the things we noticed right off the bat was the visibility around this machine,” says Powell. “Most notably, the elimination of a stack in front of the engine compartment. That now allows the operator to really see what’s in front of him, as well as a little bit lower hopper size on the machine. When you’re dumping trucks into the paver, the spotter that stands next to the machine can see in the hopper, see when it’s filled, see when the truck is empty and has better visibility into that area.”

Smooth material flow

Smaller augers deliver smooth material flow at narrow widths, helping contractors achieve quality targets. The 14-inch diameter augers efficiently move material through the auger chamber. Operators can control each material feed sensor when using cut-off shoes or when paving at narrow widths. Simply switch to manual and use the proportional control dial for the feed system.

Toyota Boosts Power, Safety, Looks on 2022 Tundra

Toyota’s slow reveal of its 2022 Tundra has finally culminated in an impressive grand finale that clearly sets the full-size truck apart from previous iterations.

Aside from a bigger truck that’s more refined and includes more driver-assist technologies, the 2022 Tundra is more powerful.

Though fans may lament losing the long-running 5.7-liter V8, they may find solace in a more powerful 3.5-liter V6 that offers 389 horsepower and 479 pound-feet of torque. A hybrid 3.5-liter i-FORCE MAX offers 437 horses and 583 pound-feet of torque. Both variants are bolted to a new 10-speed automatic. For those keeping score — and who doesn’t? — the outgoing 5.7 offers 381 horses and 401 pound-feet of torque.

More power and anew high-strength boxed, steel-ladder frame that the 2022 Tundra shares with the 2022 Land Cruiser offer a jump in max towing from 10,200 pounds on the 2021 model to 12,000 pounds and a max payload capacity of 1,940 pounds, an increase of 210 pounds.

Lackluster fuel economy in the dated 5.7, which comes in at 13 mpg city and 17 highway, will surely be bested by the more fuel-conscious V6s, but we’ll have to wait on final EPA numbers.

A new interior offers creature comforts for driver and passengers alike, including a 14-inch infotainment touchscreen, available panoramic roof, heated and ventilated front seats, rear sunshade, heated steering wheel.

The instrument panel can be optioned with conventional gauges or a 12.3-inch instrument panel display.

2022 Toyota Tundra’s new interior comfortsToyotaA host of new tech features are found throughout Tundra as well, such as towing aids, off-road enhancements, an all-new multimedia system featuring wireless Apple CarPlay and Android Auto and over-the-air updates.

Two different four-door layouts are available, as well as various bed lengths, including a 5.5-foot bed, 6.5-foot bed and an 8.1-foot bed.

Safety first!

Toyota Tundra was the first full-size truck to feature automated emergency braking, and starting with the 2022 model, every Tundra comes standard with Toyota Safety Sense 2.5.

The Pre-Collision System with Pedestrian Detection (PCS with PD) features multiple enhancements, including not only detecting the vehicle ahead but also a pedestrian in low light, bicyclist in daytime, an oncoming vehicle and a pedestrian at intersections when making a turn.

At intersections, the system is designed to detect an oncoming vehicle or pedestrian when performing a left-hand turn and provide audio/visual alerts and automatic braking in certain conditions. Additional PCS functions include emergency steering assist, which is designed to stabilize the driver’s emergency steering maneuvers within their lane while avoiding a pedestrian, bicyclist or vehicle.

2022 Toyota Tundra boasts a multitude of safety features.ToyotaTundra will be equipped with Dynamic Radar Cruise Control (DRCC). Lane Departure Alert notifies the driver by sound if it senses the vehicle is leaving the lane without engaging a turn signal. When DRCC is set and engaged, Lane Tracing Assist (LTA) provides a slight steering force to help center the vehicle in its lane using visible lane markers or a preceding vehicle.

Automatic High Beams detect preceding or oncoming vehicles and automatically switch between high-beam and low-beam headlights. Road Sign Assist (RSA) is designed to recognize certain road sign information using a forward-facing camera and display it on the multi-information display (MID).

Toyota’s Rear Seat Reminder comes standard on all 2022 Tundras. The feature can note whether a rear door was opened within 10 minutes of the vehicle being turned on, or at any time after the vehicle has been turned on, with a reminder message in the instrument cluster after the engine is turned off, accompanied by multi-tone chimes.

In addition to the TSS 2.5 system, the standard Blind Spot Monitor (BSM) helps detect and warn you of vehicles approaching or positioned in the adjacent lanes. Rear Cross Traffic Alert (RCTA) can offer added peace of mind by helping to detect vehicles approaching from either side while backing out and alerting you with a visual and audible warning. The available Parking Support Brake is designed to implement brake control when there’s a possibility of a collision with a stationary object, approaching vehicle or while parking.

Improved suspension and handling

The 2022 Toyota Tundra’s new multi-link rear suspension drops rear leaf springs for coil springs, which leads to improved ride comfort, stability, handling and increased towing capacity.

The front of the truck gets a new double wishbone suspension, which offers a kingpin offset angle reduction to improve straight-line stability and high-speed driving.

The caster trail gets a 1-inch boost for added stability. To improve cornering, roll steer has been reduced by 25% compared to the benchmarks, and the roll height center has been elevated (152mm compared to 104mm, or roughly 6 inches compared to 4 inches) to reduce body roll, especially when cornering.

The 2022 Tundra gets twin-tube shocks at the front and rear of each truck. The shock absorbers feature triple-oil seals and extended dust covers for added protection and durability. New aluminum forged knuckles are used to cut weight. TRD Off-Road packages offer monotube Bilstein shocks.

TRD Pro grades get 2.5-inch diameter Fox internal bypass shocks that provide a 1.1-inch lift up front. The aluminum-bodied front and rear shocks feature piggyback reservoirs to house additional oil for improved off-road performance. The shocks use a new polytetrafluorethylene-infused (PTFE) Fox shock fluid to improve on-road comfort. This fluid includes microscopic particles infused with the oil to reduce friction.

The all-new Tundra will go on sale in December.
