New leadership at Tigercat

Tony Iarocci steps away from the role of president with Grant Somerville replacing him.

Tony Iarocci will now join the board of directors effective October 16, 2017. Tony has held the position of president since Tigercat’s inception in 1992, steering the company through rapid growth both in terms of product development and geographic market expansion in a tough competitive landscape, major economic downturns and other challenging externalities.

Tony was involved in the initial research of potential business opportunities that was necessary to warrant the formulation of a new company, recruiting start-up staff, product development and all the sales, marketing and customer service functions that went along with his role.

Tony will be passing his day to day responsibilities over to Grant Somerville. Grant began his career in the forestry industry in 1978 as a harvester operator. He is a long serving executive at Tigercat who worked with Tony at Koehring Waterous in the early eighties on several development projects, including the design of the company’s first purpose-built track feller buncher. An integral part of Tigercat, Grant has led many important design initiatives since joining the team in 1992 and has held several positions with increasing degrees of responsibility, including product manager for track machines, advanced engineering, and most recently vice president, engineering. 2017 marks his 40th year working within forestry and machinery manufacturing.

CEO of Tigercat, Ken MacDonald, indicates that because Tony’s health is still very good, he has agreed not only to join the board of directors but to continue to contribute to the company’s growth, focusing on the recruitment and development of design talent and working with fellow team members and suppliers on both product and component improvement.” Tony will also consult on special projects and new product development.

John Deere adds the 1910G to its forwarder line-up.

The 1910G is the largest model in the John Deere forwarder line

The 1910G forwarder is equipped with a Final Tier 4 200 kW (268 hp). The maximum engine output has increased by 7.5 percent and torque by 21 percent compared to previous models. The drive hydraulics have also been increased, with the transmission having 4.5 percent more tractive force. The 1910G forwarders allow operators to carry even larger loads. Other features that were popular with customers have been retained, such as the improved operator cab and configurable joystick controls.

One of the key features on this model is the adaptive driveline control, which John Deere indicates is a first in the forestry industry. This software-based control system improves the productivity and drivability of this G-Series forwarder, and enables the operator to choose the desired RPM setting (Eco, Normal, Power) for the operating conditions. The system automatically adjusts the engine's RPMs to correspond with the engine load. In high-load situations, the driveline control ensures that the diesel engine runs smoothly and uses the maximum available tractive force efficiently.

Another feature is the larger load capacity. The cross-sectional area of the wide load space is bigger and the new-generation headboard provides excellent visibility to the load space. Additionally, the CF8 boom on the 1910G moves smoothly and seamlessly, increasing accuracy and efficiency. Boom control is improved using Intelligent Boom Control (IBC). IBC is a technology that improves operator productivity by automatically controlling the lift, slew and extension of the boom based on the location of the grapple. IBC increases accuracy and, ultimately, the number of loads per each work shift. Additionally, configurable joystick controls allow the dealer to quickly reconfigure the machine to meet the preference of the operator. The operator can select one of three configuration options, providing the operator with an intuitive system.

The 1910G, as well as the rest of the G-Series Forwarder line, is equipped with the TimberMatic™ F-16 control system. The control system features a configurable user interface, cruise control and inclination display, increasing operator efficiency. Additionally, the new software offers service personnel remote access to the machine. New MECA control modules, simple CAN busses and a streamlined electrical system improve the efficiency of machine functions.

The 1910G is available with two cab options, fixed or rotating and levelling. The rotating and levelling cabin helps the driver to maintain the correct working positions to reduce strain on the back and shoulder areas, even when working on uneven terrain. With a cabin rotation of 290 degrees, the 1910G model offers a view of the boom and grapple, enabling safer, easier log loading. The large windows of the cab allow for virtually unrestricted all-around visibility. Other fatigue-beating features, including ergonomic armrests, a fully adjustable air-cushioned seat and an automated climate-control system, help to boost operator productivity. All John Deere forwarders come standard with JDLink™ in base for five years. This remotely connects owners and managers with their equipment and local John Deere dealer. They have access to alerts and machine information, including performance and maintenance data, allowing them to better manage where and how equipment is being used. Source

The basics of backhoe maintenance

We discuss how to ensure a long and productive life for any backhoe.

In this article, produced by Case, it is explained that habit-forming routines and a basic understanding of changes brought on by Tier 4 emissions are required. The proliferation of Tier 4 Final equipment – with greater fuel and fluid tolerances/demands – also requires attention and understanding from everyone in the machine management cycle. The following aspects should be carefully considered:

  • The owner’s manual: Inside each owner’s manual is a detailed service interval schedule that should be followed.
  • The pre- and post-operation walkaround: This is the most important few minutes of the day in the life of the backhoe. Check the oil and hydraulic fluid levels, check tire pressure and condition (especially important given how much time backhoes spend in travel mode), and grease as needed. Take in the overall condition of the machine. Look for visible damage, or leaks, or anything else that might be out of order or indicate something that would impede the operation of the machine. Check for cracked paint around the backhoe and loader arms where they could be susceptible to high stress. Cracked or spider-webbed paint could be an indication that the metal structure beneath is cracked and should be investigated to ensure there’s no serious damage. Inspect the condition of the buckets and/or attachments, and ensure that all are properly engaged. Check belts and auxiliary connections. Identifying possible mechanical issues with the backhoe, either at the beginning or the end of the day, will ensure that it is fixed and cared for properly before it turns into a costlier downtime event. This is especially important at the end of a shift where repairs can be identified and addressed before the start of the next day/shift to avoid downtime.
  • Diesel exhaust fluid (DEF): DEF is not difficult to manage or handle. Like other fluids, it likes cool and dry storage (although shelf life even at 86 degrees is still 12 months). It should be stored and dispensed in dedicated containers so as not to allow for any contamination (even minimal contamination of DEF can lead to degraded performance and eventual failure of the SCR system). Always buy DEF from a reliable source, and always use DEF that is ISO 22241 compliant.
  • Organic acid technology (OAT): OAT is an extended life coolant that provides increased protection to the engine and better performance throughout its service life. Tier 4 Final backhoes feature a clearly marked decal near the fill point that indicates the use of OAT, and the brand specified by the OEM. This is also detailed in the owner’s manual. Conventional coolant cannot be mixed with OAT, and off-brand/off-spec coolant (separate from what is specified by the OEM) can diminish its extended life properties and cause compatibility issues when mixed.
  • Oil: Modern Tier 4 Final backhoes require a low-ash oil, CJ-4, that previously was not used in older equipment. This low-ash oil stands up to temperatures better than older formulations, and is backwards-compliant to older machines and trucks with diesel engines. The converse is not true, however. Older oils cannot be used on Tier 4 Final equipment that specifies CJ-4. Always refer to the owner’s manual for oil specifications required for that machine.

In the next issue of Logging-on, we will further explore options for backhoe maintenance. Source

Komatsu Forests utilises a new environmentally friendly colour marking solutions

The paint used for marking logs must be of excellent quality and not be harmful to the environment.

Colour marking of the wood is one part of many in the harvesting process. It is important that the paint is of the right quality. Colour marking (CM) facilitates the handling of the processed wood and is often a prerequisite for the correct product being delivered to the sawmills. An important factor is the colour intensity. Where alcohol-based paints have a relatively low intensity and glycol-based paints have a medium intensity; both types have problems with the colour spreading easily over the cut surface. Komatsu CM is a water-based product and has a high intensity while not easily spreading over the cut surface. This leads to clearer and more visible markings that help the operator while reducing colour consumption.

It is also not normally desirable for the paint to penetrate the wood as it can reduce the price dur to waste of the log ends. Paint based on both alcohol and glycol have problems with the paint easily penetrating too deep into the wood, causing a lot of wastage for sawmills. Komatsu CM only adheres to the top layer of the wood, about 2-4 mm. Another advantage is that Komatsu CM does not cause any corrosion, which is usually a problem with alcohol and glycol-based paints.

For both the environment at large and the operator’s work environment it is very important what the paint consists of. Glycol is hazardous to health while methanol belongs to the group of chemicals that are toxic and can cause health damage. Komatsu CM uses water-based paints with additives used in the food industry. It lacks warning signs all together and is completely harmless to humans and to the environment. Source

Sennebogen introduces their new Maxcab operator workstations

The new cab provides more room, more comfort, a better view and is even quieter inside than before.

Sennebogen launched the first generation of the Maxcab in 2006. The new version of the Maxcab is 70 mm longer. This not only makes the driver feel less cramped, but also provides extra space for an electric cooler and a storage area for documents and folders behind the driver seat. The flexibly adjustable and air-conditioned driver seat and the consoles and ergonomic joysticks that move with the seat create the perfect environment in the cab for long periods of fatigue-free work. The workstation can be individually adjusted to the size and weight of every driver, ensuring the best possible working posture.

The sliding door continues to provide the same safe access to the cab. The opening width of the door has been enlarged compared to the previous model. The cab windshield has been pulled down to the base plate, optimizing the view to the front. Together with the large side window panels, this provides a panoramic view over the entire work environment. The new floor mat is flush with the access opening, making the floor easy to clean.

All of the operating elements are easy to understand and intuitive to operate. There are charging sockets for electrical and electronic devices on the right behind the driver seat to ensure that all necessary devices are always ready for use. Additional storage places in the interior keep things tidy and within reach inside the cab. The air conditioning in the cab has been improved by means of optimized air conduction with a total of 9 outlet nozzles. The Maxcab has optimal distribution of cooling air throughout the interior. Even at a high cooling output, the air is blown in at low speed via outlets distributed around the cab, even at roof height. The cab still features a side window panel which can be opened in the driver door and an adjustable windshield with an improved operating mechanism, both of which help to ensure a pleasant working environment. The window panels behind the B-column are tinted and reduce the amount of cooling power required for the cab.

The new cab uses sound-absorbing materials and structural solutions to significantly reduce the noise level in the cab once again. Source
