Bobcat Launches New TL470HF Telescopic Handler

   The tracer emits ultra sonic signals to maintain a set distance or elevation from an object, surface or the ground. Installed on the blades of the 244 and 274 cm graders, the sonic tracer allows them to be used to grade, level, and backfill on a multiple slope terrain when following a string line, kerb stone, the gutter or even a previous pass as a grade control. Grade accuracy is 6.4 mm, and the detection range of the sonic tracer is from 200 to 1300 mm.

The system comprises a sonic tracer, two slope sensors and one rotation sensor, all of which are Trimble components so have proven reliability. The sensors communicate directly with the Bobcat Attachments Control Device (ACD).

The sonic tracer and large graders are compatible with Bobcat S770 and S850 skid-steer loaders, the Bobcat T650, T770 and T870 compact tracked loaders and the Bobcat A770 all-wheel-steer loader. If the user already has a laser system mounted on the grader, they can also mount the sonic tracer on the blade, allowing them to switch between using the grader with the sonic tracer or the laser system.

Geith launches new automatic couplers

Geith is launching new safety-focused, automatic quick couplers for a range of excavator sizes at Intermat 2012.

The new QC35/40 hydraulic coupler is designed for use on mini-excavators from 2 to 4 tonne in weight and expands the range of Geith couplers to cover excavators from 2 to 90 tonne.

These fully automatic couplers ensure a safe changeover of attachments without the need for the operator to leave the excavator cab. A patented double pin locking system ensures that the coupler retains the attachment in a safe position even if there is a loss of power.

Clearly visible from the cab, the front safety lock is activated by a powerful spring and hydraulic cylinder. This design offers a clear advantage over gravity systems, which is especially important when working in very difficult and dirty environments.

As safety is a core value at Geith, the company is participating in the ISO Working Group aiming to create a new International Quick Coupler Standard, which is scheduled for publication in 2013. Since the new Standard is still under development, no company can claim to be compliant. However, Geith has ensured that all its couplers comply fully with all current national standards and safety regulations, and will continue to do so in the future.

The focus on safety has led to increased complexity in some coupler systems, compromising on reliability and performance. By contrast, Geith has continued to focus on developing the simplest, most reliable and safest couplers with few moving parts and no grease points so there is a limited need for maintenance.
