Doosan Bobcat EMEA has launched a new hydraulic pin grabber coupler for attachments used on seven Bobcat compact excavators the E25 up to the E55 models. The new Bobcat Hydraulic Coupler is available both as a factory-installed option and as an aftermarket product for use with pin-on fitting attachments for the E25 to E55 excavators. The new quick coupler complements the existing full range of mechanical couplers from Bobcat including Klac and Lehnhoff systems.
Bobcat excavators, equipped with a factory-installed hydraulic coupler, are now supplied as tailor-made systems. All controls are incorporated into the operator area, so there is no need for additional controllers, switches, displays, hoses and/or wire harnesses to be connected. The factory-installed option is designed not to compromise machine efficiency, robustness and overall performance.
Key features and benefits of the new quick coupler include its triple lock design for greater safety, exceeding the ISO 13031 norm and complying with all industry safety standards in Europe and the UK. There is a wide variable pin center, to pick up multiple pin-on attachments. A robust, yet compact design enures maximum breakout force and the system is essentially maintenance free, with few components for peace of mind. Powerful springs are activated in case of pressure loss to avoid any risk and reversibility is standard when the job requires it.
Important aspects include the increased safety and compliancy offered by a hydraulic pin grab coupler, which enables the operator to rapidly and safely change between non-hydraulic attachments from the comfort of the cab. The pins in the system are under constant pressure from the hydraulic cylinder ensuring the attachment is tightly gripped, even when there has been pin wear over longer term use. In the unlikely event of a hydraulic cylinder failure or hydraulic pressure loss, the attachment will remain securely connected thanks to two powerful springs. Front and rear locks ensure the attachment remains in position at all times.
The operator can change non-hydraulic attachments without leaving their seat. This means more comfort for the operator, as well as higher productivity, because the attachments can be changed more quickly.
The proven design has no greasing requirements and no maintenance requirements (besides a daily inspection), making the coupler hassle-free.
