Tech review - tracked log loadersCat 538 LL Forest Machine and 558 LL Forest Machine

Caterpillar

The Cat 538 LL Forest Machine and 558 LL Forest Machine are versatile, purpose-built log loaders that can be customized to perform a range of loading tasks to deliver maximum profit potential to loggers.

The first models in the 500 series to meet U.S. EPA Tier 4 final emission standards, they increase profitability by maximizing efficiency and reducing costs. They feature outstanding fuel efficiency while increasing horsepower and swing torque.

Cat log loaders are available in numerous configurations for log loading, shovel logging, butt-n-top/power clam applications, and millyard applications. Cat offers both an under/under configuration, which consists of a traditional under-mounted heel cylinder for loading and shovel logging, as well as an over-under configuration, which is optimized for stacking height.

The Cat 538 and 558 feature a new machine design, new engine, and enhanced hydraulics. Machine and hydraulic performance are boosted by increased engine horsepower for strong multi-functioning and improved performance — and more production.

Uniform speed control maintains a constant engine speed regardless of load. Coupled with other features, both models deliver excellent fuel economy.

The machines are engineered for durability and reliability with proven Cat components, purpose-built upper and lower frames, and increased cooling capability to maximize machine uptime.

The Cat 558 LL is available with a rear entry cab option that offers unparalleled operator experience with safer access, improved operator comfort, increased visibility, and an innovative cab lock down system to help maximize machine uptime.

DoosanDoosan

Doosan Construction Equipment has manufactured log loaders since 1999. Today, Doosan offers three models, including the DX225LL-5, DX300LL-5, and DX380LL-5. The DX380LL-5 is the newest model and was introduced in fall 2016 at the DEMO trade show in Vancouver, B.C. It is designed to serve forestry professionals in shovel-logging tasks. The DX380LL-5 has high-swing torque and approximately 44 feet of reach.

Doosan log loaders are manufactured with heavy-duty components and application-specific guarding to keep them running strong and to help minimize downtime. Doosan log loaders are built with a high, wide undercarriage for excellent ground clearance. They have thick steel doors and panels to help protect internal components.

Equipped with a live heel and durable boom and arm, Doosan log loaders, when configured with a log grapple, are ideally suited to stabilize logs and efficiently sort, stack, and load them onto trucks.

Options for Doosan log loaders include a forestry cab for states and provinces with additional requirements; straight travel pedal, allowing operators to travel in a straight line more easily; a block heater or diesel-powered coolant heater for improved cold-weather starts; sideview camera available for viewing on the LCD screen; and LED lights for enhanced visibility when working early in the morning or at night.

Doosan offers two durable log grapples for use with its log loaders—the LG52 with a 52-inch arm opening and the LG58 with a 58-inch arm opening. Log grapples complement the log loader’s live heel for efficient operation.

John Deere G-SeriesJohn Deere

Designed to increase operator efficiency and performance, the John Deere G-Series log loaders are proving to raise the bar for productivity and efficiency. With four models suitable for a wide range of applications, the 2156G, 2656G, 3156G, and 3756G offer superior operating comfort, featuring larger, quieter cabs with standard rear entry allowing for easier entry and exit. Polycarbonate windows stand up to the harshest conditions, while strategically placed floor windows offer improved visibility of the tracks. The cab-forward option increases right-side visibility by positioning the operator 17 inches further forward than standard cabs. 

“We know keeping an operator comfortable is a key factor in maximizing productivity,” said Dave McFarlane, marketing manager, Deere-Hitachi Specialty Products. “We made a significant investment in the cab design of these machines, and our customers are really noticing the improvement.”

In addition to the redesigned cabs, these models offer a host of features designed to improve machine uptime and performance. The newly-designed G-series hydraulic systems are more efficient, improving productivity and lowering the cost of operation. All models are equipped with a powerful PowerTech Plus engine.

Additionally, improvements in lower rollers and XD and LC undercarriages extend machine life while a 30 percent reduction in electrical components has reduced electrical-related downtime. Hardened steel bushings in the boom tower on the two largest models extend joint life and simplify repairs. These features, combined with the JDLink machine monitoring system, help keep machines at peak performance levels, ensuring the highest level of uptime and productivity.

Komatsu PC290LL-11Komatsu

Komatsu America Corp., a leading global heavy equipment manufacturer, recently introduced the new PC290LL-11 to its current log loader product lineup. Featuring a 196 net horsepower, EPA Tier 4 Final Komatsu SAA6D107E-3 engine, the new PC290LL-11 is available in either a 40’ reach live heel log loader or a 34’ reach road builder configuration, for high performance in demanding logging applications. Log loader and road builder operating weights are 89,730 lb. and 82,230 lb., respectively.

Other new or improved PC290LL-11 features include a high capacity cooling system, high drawbar pull, additional forestry guarding, narrower, 11’5” transport width, more comfortable operator controls, all LED lighting, and KOMTRAX 5.0 technology.

It features a new high capacity cooling system, utilizing wide core cooling fins for the radiator, hydraulic oil cooler, and charge air cooler, providing improved performance and reliability. The heavy-duty 1/4”- thick cooler air intake door is waffle-screened and sealed to reduce debris accumulation and cleaning time.

It generates 64,250 lbs. of drawbar pull, and a rugged PC390-class swing motor and drive deliver high swing torque for superior log loading and road building performance.

The guard system now has a fully protected LED light, plus a rugged tree deflector with a “hockey stick” design that can be removed or reverse-mounted for transport. Along with the tree deflector, the track frame steps can also be removed or reverse-mounted to achieve an 11’5” transport width, which meets most local regulations and reduces the need for special transport permits.
