New and Noted at DEMO 2008
The Demo 2008 show, held in Halifax in September, featured lots of working logging equipment and was a tremendous source of informationwith plenty of new equipment, products and services on offer.
When it comes to the latest technologies in logging equipment, Demo 2008 attendees pretty much saw it all during the three-day run of the very successful show, held in September just outside Halifax. This marked the first time Demo was held in the Atlantic Provincesand show organizers Master Promotions and the Canadian Woodlands Forum got it right, with lots of positive comments coming from those attending and from exhibitors.
The world-class event is one of North America’s largest and most unique outdoor equipment showsit featured over 100 exhibitors on a three-kilometre loop in the forest for a live exhibition of forestry-related equipment.
The show was proudly hosted by Ledwidge Lumber, a family-owned sawmill located in nearby Enfield, Nova Scotia, on one of their sustainably managed woodlots.
And there was plenty of equipment to see over the three days. Logging & Sawmilling Journal highlights some of the new equipment on display at Demo below.
Volvo making bigger splash into forestry equipment market
The carrier without attachments weighs in at 75,700 lbs, with the Volvo extreme-duty forestry undercarriage.
It comes with an enhanced-for-forestry hydraulic system. The heart of the hydraulic system is the engine driven, series mounted, variable displacement axial piston pumps that provide high flow performance. A fifth dedicated hydraulic pump is added for feller buncher saw head operation.
The heavy-duty forestry boom and arm with dual boom main cylinders is designed and built to withstand the lifting and twisting forces of the toughest harvesting operations.
Standard equipment includes a variable speed reversible cooling fan that is electronically controlled and hydraulically driven to reduce fuel consumption and noise.
The newly designed Volvo Forestry Care Cab features a multi-adjustable heated seat, enhanced operator comfort system and easy-to-read displays providing real time information on all machine functions.

It comes equipped with a heavy duty ball bearing rotate gear, and the hoses go through the rotate for better protection.
The 3022 head itself has a cutting capacity of 21.5”and a 53” saw blade. It has a maximum front opening of 38” and is able to accumulate from a 4.53 sq ft area. With the 350 degree high rotation wrist, it weighs in at 6,500 lbs.www.gilbert-tech.com
Demo attendees able to evaluate new John Deere E-series machines
Deere’s four new harvester sizes, from the 1170E four-wheel version to the larger 1470E, as well as its new E-series forwarders, come equipped with the new cab design. It is an elliptically-shaped cab. The harvester cab rotates 160 degrees, providing the operator with more visibility. Its side-to-side and front/back leveling is greater than the forwarder, recognizing that the operator must sometimes work at awkward angles for both felling and processing activities.
John Deere is also introducing six new E-series forwarders. The 1510E, for example, is an eight-wheel machine where the cab rests on a turntable between the front bogie axles and rotates 290 degrees to follow the movement of the boom from the forest floor to the bunk as the operator picks up the grapple load.
The E-series also comes with a number of mechanical improvements, as well as availability of the Timberlink monitoring system that constantly analyzes machine performance, the duration of each of the work phases and fuel consumption of each phase. The harvesters also use the TimberMatic H-09 measuring and control system, which allows the operator to fine tune and adjust the boom and head, as well as many other settings on the fly. www.deere.com
STL presents new lubrication technology for chain saws
Its trademarked Envirosys product is an original management concept that combines a central lubrication system with Envirosys greasea vegetable oil-based lubricant that is biodegradable. The product has specifically been developed and adapted to the most severe conditions and environment for logging equipment.
STL says the system is easy and quick to install, generally within four hours by its own technicians. The concept is totally independent from the current lubrication system, and its design allows for optimum control of the cutting performance based on the operator’s setting. They can select the proper rate at their fingertips, according to their needs.
Advantages of the Envirosys product include: significantly reduced volume of lubricant used; an extension of equipment component lifespan; reduced cleaning costs; elimination of the recycling costs of plastic containers; increased cleanliness; reduced lubricant adding frequency, eliminating risk of injury during filling and eliminating discharge of toxic hydrocarbons.
Cat C-Series skidders built for lower maintenance and higher productivity
The 220 hp, 535C skidder is offered with a new DualHP option that provides increased power in second through fifth gears.
The five-speed transmission matches engine power to the load size and ground conditions and electronic shift control (ECPC) boosts total productivity. When the lock-up torque converter is engaged, travel speeds can be as much as 15 per cent higher.
Caterpillar bunching grapples feature a strong box-section design and higher clamping forces for faster log loading and excellent retention. The “Auto-Grab” grapple hydraulic system monitors and adjusts tong pressure as needed to maintain a secure grip on grapple loads without wasting power. www.cat.com/forestry
Hultdins portable bridge aims to make logging operations more productive
The portable bridge is said to be easy to transport, handle and position, providing logging operations with extra harvesting time each year. It minimizes stream and ground disturbance, is built for repeated use and different locations, as well as rapid installation and removal.
The Hultdins Terrainbridge 500 measures 16’ long, 4’ wide, 2’ tall, and weighs 1,370 lbs. It is constructed of high-strength steel sections, all connected by steel cables, like an inverted suspension bridge. This unique design concept makes it vertically strong and flexible on the longitudinal direction so that the bridge adjusts itself to all types of terrain.
The bridge is easily loaded and transported on a forwarder, and is also easy to handle with the forwarder crane wherever the bridge is being built. It will carry the largest and heaviest forwarders, but is so light that smaller forwarders can also move it. www.hultdins.com
New Tigercat 635D skidder designed to transport large, heavy payloads
It is designed to haul large, heavy payloads in difficult terrain as well as sensitive site applications. The long wheel base and wide-spread bogie axle minimize ground pressure and maintain front wheel traction.
The skidder has also been designed with extreme duty in mind with strength optimized frames, consisting of a strong centre section and robust wide spread rear bogie axle.
Equipped with a Cummins QSB 6.7 Tier III engine, it delivers 260 hp at 2,200 rpm, and is capable of reaching a top speed of 13.5 kms per hour. The enhanced hydrostatic drive system has an extremely efficient driveline, automatic variable engine speed for high fuel efficiency, and an operator-controlled maximum speed setting. The electronic control system has also been enhanced for improved user interface, better fuel economy, and provides precise control of all machine functions.
In terms of operator efficiency and cab comfort, the skidder has a two-position rotating seat and joystick steering for improved ergonomics. The grapple and arch functions are controlled with one joystick. It also comes with a choice of dual cylinder grapple options. www.tigercat.com
Automatic seat leveler improves operator comfort/productivity
Studies conducted by the Swedish Institute of Forestry Research indicate that about 50 per cent of forest machine operators have musculo-skeletal disorder of varying degrees because of sitting in tilted positions.
The Sit Right F/B-Tilt is a complete unit and has all functions built into the unit and the control box. With the control box, the operator can program functions such as leveling speed, tilt (11 degrees forward and eight degrees backward) and the Home position. It can also be preset to three different driver profiles.
One study shows that productivity can increase between four to 11 per cent if the operator is sitting properly in the forestry cab. www.wallingfords.com
Alliance offers multiple forestry tire options
The Forestar series was developed mainly for modern and sophisticated forestry equipment. For example, the LS-2 directional tread design with strong, high and durable lugs is capable of dealing with the toughest forestry conditions. Basic nylon tire structure is reinforced by strong steel breakers as an efficient puncture protector, as well as an additional global tire strengthener.
A special durable “forestry” tread compound, together with high undertread gauge and strong, thick sidewalls enables long and secure work in the forest. www.alliance-tires.com
