New quick coupler for Bobcat excavators
Bobcat has worked closely with Klac Industrie of France to develop new quick coupler for fitting attachments to the Bobcat mini-excavator range.
To ensure optimum performance when using attachments on Bobcat mini excavators, the quick coupler incorporates several modifications to Klac's standard system The launch of the new quick coupler meets an increasing trend in Europe to use mini-excavators as tool-carriers and is one of three different quick coupler systems now available for use on the Bobcat mini-excavator range

Bobcat launches enhanced 1.6 tonne mini-excavators
Bobcat, manufacturer of the widest range of market-leading compact equipment, has launched new enhanced versions of the company's 320 and 322 1.6 tonne mini-excavators.
Bobcat 323 mini-excavator digs deeper and faster.
New 323 mini-excavator meets a market need for a very compact mini-excavator with greater reach for digging and loading.
The new Klac-type coupler is available in four sizes for all Bobcat mini-excavators from the 319 up to and including the 442 model.
The new coupler is very compact, retaining the original geometry of the pin-on buckets for optimum performance and to provide an equivalent breakout force to the pin-on system.
One of the key advantages of the new quick coupler is that it is wear compensating.
Both the mobile locking plate and the fixed anvil have a matching tapered surface that works as a wear-compensating system.
When the coupler is closed against the bucket, it is centred by two surfaces machined in a 'V' or wedge shape.
The wear-compensating system eliminates any free play in the system.
Two polyurethane bumpers act as a compression spring to apply pressure on the locking plate to ensure a secure coupling.
Complete safety is ensured at all times, even if both springs are broken.
Another safety feature is that unhooking (as well as hooking up) always occurs in two stages.
Thanks to the pivots built into the coupler, the bucket can be picked up easily from the ground.
The bucket is automatically centred and the mounting hooks are locked gradually when the coupler is closed, preventing accidental unlocking.
A special unlocking tool makes it easy to release the bucket.
The tool is supplied standard with every coupler.
Once released, the bucket remains safely suspended from the pivot of the coupler.
The new Klac-type system complements two other quick coupler systems for Bobcat mini-excavators:.
* The Bobcat X-Change system, the first quick coupler system for mini-excavators in the USA.
* The Lehnhoff system, the market leader in Germany. Request a free brochure from Bobcat ...
