LiuGong Rolls Out Two F-Series Excavators – and One Has Zero Tail Swing

Aimed at contractors for residential and commercial construction, including grading, trenching and fencing, LiuGong has introduced two new excavators to the North American market.

The LiuGong 9027F is a true zero tail-swing, 2.7-metric-ton excavator, and the 9018F represents the smallest of the company’s F-series

The 9027F enables operators to dig parallel to the dozer blade, which is advantageous for operations close to walls and backfilling. It pushes 2,698 psi through the slew circuit. 

The excavator’s main hydraulic pump delivers 23.8 gallons per minute main and uses a proportional control valve for better management of hydraulic flow to attachments. Operators can engage the flow rate for the hammer-shear and hydraulic thumb from the monitor.

Hydraulic control for travel, boom swing, arm and bucket are engaged through travel pedals and joysticks. Auxiliary hydraulic functions are controlled by electrical proportional solenoids for precise control.

9027F Specs:

Operating weight (with cab): 6,063 poundsT4F Yanmar engine: 20.4 horsepower Max pump flow rate: 23.8 gpm Max pressure: 3,133 psi Standard bucket capacity: 0.065 cubic yards Bucket/cutting width: 15.75 inches. Bucket breakout force: 4,496 foot-pounds Arms digging force: 2,698 foot-pounds Max digging depth: 9 feet, 4 inches. Swing speed: 9.5 rpm Arm length: 4 feet, 3 inches Max dump height: 10 feet,1 inch

Even smaller and tighter is LiuGong’s 9018F compact excavator. The 9018F’s retractable undercarriage gives you access to restrictive workspaces. Its 51-inch outside-to-outside tread measurement retracts to just 39 inches, allowing it to pass between onsite obstructions and through most bay doors.

Better fuel consumption is achieved through a more efficient hydraulic system that requires 15% to 20% less engine power than its predecessor. For more precise operation, the load-sensitive hydraulic system’s main pump uses a proportional control valve, which better manages flow distribution for all attachments.

Back-filling with the dozer blade no longer requires the operator to remove his or her hand from blade control to change travel speed. By simply pressing the top of the handle, an operator can now select high or low speed travel.

More Power, Reach, Control: New Toro Dingo TX 1300 Mini Skid Steer

When the Toro Dingo line of compact utility loaders was first introduced, it was about the smallest machine anyone could have imagined. But that didn’t stop contractors from enthusiastically embracing the machine and the concept. (These machines are also called mini skid steers and utility track loaders.)

The latest version of the machine, the 1,300-pound-rated-operating-capacity Dingo TX 1300 was unveiled at the American Rental Association show in October and brings more power, reach and control to the popular platform. “This is designed for contractors who need increased power and reach,” says Jay Thaker, marketing manager, Toro.

The TX 1300 features what the company calls its Intelliscope loader arm with SmartLoad technology, giving the operator an additional 26 inches of reach. With a hinge-pin height of 109 inches, the telescoping loader arm allows material to be lifted over the side of a Dumpster or truck, giving you the same kind of versatility you would get from a skid steer or compact track loader.

Toro integrated the hydraulics and loader arm functions into one thumb-operated controller for easier, more natural operation. One hand can be used to operate the loader arm and auxiliary attachments, while the other hand operates the Toro traction controls.

“We understand that everyone needs a bit more punch, so we equipped this with a 37-horsepower Yanmar diesel with 3,000 rpms,” Thaker says. The pressure-relieving quick-coupler system makes connecting attachments simple and quick, and a larger operator platform increases operator comfort.

With a wheelbase of 39 inches and overall length with bucket of 103 inches, the TX 1300 maintains the small footprint the Dingo line is known for. But it also offers bigger capabilities than previous models, with a tip capacity of 3,714 pounds and a weight of 3,858 pounds.

The Dingo TX 1300 will be available starting this winter.

Work Begins on Freeway Outer Loop for Lubbock, Texas

Work has begun on what will eventually become an outer loop around Lubbock, Texas, starting with transforming a two-lane rural road into a six-lane freeway.

The entire seven-phase project, expected to take 20 years to complete, has been in planning for more than 10 years, according to the Texas Department of Transportation. On November 8, the department held a groundbreaking on the first two construction phases, covering 4 miles of the planned 36-mile loop.

Phases 3A and 3B are expected to take up to five years to complete at a cost of $155 billion. Sacyr Construction USA of Miami won the construction contract.

The project involves transforming FM 1585 into a freeway with frontage roads, bridges and ramps. The current road handles about 50,000 to 60,000 vehicles a day, and the loop is designed to handle future traffic for the growing city.

Crews will begin work by creating retention ponds at four locations before beginning work on an underground drainage system, according to TxDOT. The DOT plans to keep one lane of traffic open in each direction throughout construction.

Phases 3A and 3B are the first of seven phases along the 12.4-mile Segment 3 of the Loop 88 corridor. Segment 3 extends from U.S. 87 to U.S. 62/82 in Wolfforth and will cost an estimated $600 million.

Phase 3C, which includes the U.S. 87 interchange, is scheduled for construction to begin in 2026.

“We’re excited to finally turn dirt and see the hard work the TxDOT Lubbock District has put into research, public meetings and roadway designs becoming a reality,” said Michael Wittie, TxDOT Lubbock area engineer.

Lubbock Loop 88 will eventually create an outer loop around the west and south areas of Lubbock. Its construction phases are broken down into four segments, with each segment having five different sections. Bid lettings for future phases of Segment 3 are scheduled out until October 2031.
