Frame Lock is a new feature with the H-Series introduction, wheeled harvesters can be configured with active or passive frame lock. The passive system is on when the machine is still and off when the machine is moving. However, in the active frame lock system it can be engaged when the machine is driving or operating as well. The hydraulic frame lock system helps increase the confidence of operators when operating the machine, whether it is while driving and slewing or stopped and slewing a large tree.

Passive frame lock comes standard on every H-Series wheeled harvester. As said above, this system is dependent on machine movement. When the machine is still, the frame lock is in locked position, therefore the oscillation between the two frames is prevented by hydraulic cylinders.

Active frame lock is an optional upgrade on wheeled harvesters. This system works when the machine is moving or stopped. In active frame lock, the stabilizing force from the hydraulic cylinder force is adjusted according to boom angle and lift cylinder pressure.

• Operator confidence
• Engages while driving
• Helps increase stability when maneuvering over obstacles
• Helps increase ground pressure when working on slopes

Intelligent Boom Control (IBC) smooths boom operations, making them more precise and efficient, to increase operator productivity compared to a wheeled harvester without IBC. IBC allows operators to control the direction of the boom tip directly instead of controlling independent boom movements. IBC also utilizes adaptive swing control to adjust the swing speed based on the overall position of the head. This makes controlling the head more precise and intuitive, especially for new operators, compared to machines without IBC.

Harvester IBC 3.0 is an optional upgrade for wheeled harvesters. When a machine is configured with IBC 3.0, the swing bearing is equipped with a rotation sensor. The additional sensor helps when operators are slewing trees for smooth movements as well as positioning of a stem on TimberMatic™ Maps.

Benefits

• Customizable control pattern and boom motions
• More efficient and consistent boom movements
• IBC functions have been adapted to the work cycle
• Automatic adjusting of the harvester head in accordance with the trajectory of the boom
  • Trajectory of the boom can be adjusted through the secondary display unit

The H7 boom is a new release with the 1270H wheeled harvester. This boom provides an increase in lift and slew torque, and larger working tilt angle compared to the previous CH7 boom. With the increase in boom performance, operators can more easily handle larger timber. There are multiple boom lengths to meet your customers’ needs when configuring the machine.

• More lift and slew torque compared to CH7 boom
• More push and pull force compared to CH7 boom
• H7 boom tilt angle greater than CH7 boom
• Jib cylinder direction change
  • Less points and levers compared to previous boom
• Low center of gravity

The new three-pump hydraulic system provides a 15% increase of hydraulic power over the previous G-Series. The three dedicated pumps for the harvester head, boom, and drive allow for simultaneous operation of each machine function while meeting operator’s requirements. The hydraulic pumps feature a positive gear ratio, which helps achieve increased pump power while maintaining low engine revolutions per minute (RPM).

We also see an increase in feed roller pressure in the harvester head. 350 bar pressure on the H-Series compared to 280 bar pressure on the G-Series. Less hydraulic flow is needed for the same hydraulic power, helping to drive higher efficiencies with less fuel consumption.

• 15% increase in hydraulic power
• Dedicated pumps for the harvester head, boom, and drive
• Lower engine RPMs
• Increased feed roller pressure

The H-Series operators station rotates 220 degrees to follow the boom and harvester head slew. The 220 degrees is an increase compared to the 160-degree rotation on the previous G-Series machines. The operator’s station is also automatically leveled, by hydraulic cylinders and happens as the machine navigates slopes or obstacles.

Along with the increase in operator station rotation, the redesign of the rear frame, rear bumpers, boom design, and slew cylinder location has helped increase visibility. The rear hood and bumper now sit lower than the G-Series layout, this helps operators see behind the machine especially with the operator’s station rotated.

• 220-degree rotation of the operator’s station
• Auto rotate flows the boom and harvester head movement
• Automatic leveling of the operator station
• Increased visibility compared to G-Series
• Rotation and leveling speeds can be adjusted through Primary Display

The 1270H Wheeled Harvester has multiple axle and tire configurations to fit your customers’ needs. A six-wheeled configuration is versatile to handle everything from thinning to clear-cutting. The larger tire options provide higher ground clearance needed to navigate deep snow, rocks, or other debris when working.

An eight-wheeled configuration helps improve stability and reduce ground pressure when navigating the logging site. Whether harvesting on steep slopes or maneuvering through soft soils, the eight-wheeled harvesters can handle it all. Additionally, tracks can be added to this configuration which will also help to reduce ground pressure and maximize traction.

• Multiple axle options to fit your customers’ needs
• Various tire sizes to reach different ground clearance heights
• Ability to work in many conditions
• Tracks available to help reduce ground pressure and maximize traction
