With up to 10 percent higher fill capacity compared to other available clamshell grapples, you can transfer large volumes of loose material such as grains, coal, sand, and gravel. Move production-sized loads with the wide shell opening for bulk material. The powerful closing force of the grapple shells combined with fast opening and closing time helps you shorten your cycle times and stay on task to move more tons per hour. The Cat PL161 Attachment Locator is a Bluetooth device that makes finding your attachment quick and easy. The machine’s onboard Bluetooth reader or Cat App on your phone will help you locate the device automatically. Utilizing Cat Payload for Excavators, you can achieve precise load targets and increase loading efficiency with on-the-go weighing and real-time estimates of your payload without swinging. Cat machines are pre-programmed with optimum performance settings for your grapple to maximize the pairing and efficiency of the machine and grapple.
The cylinder hoses are internally fitted in the structure with two removable maintenance panels to help provide optimal protection while working. High quality and wear resistant materials are used, especially in the shells. Pivot points equipped with dust seals and sleeve bearings will help to enhance product life. Equipped with snubbers, the two high quality cylinders cushion the opening movement of the shells to handle hydraulic pressures up to 5,076 psi (35,000 kPa) and allow for smoother operation with less vibrations in the cab. Two lifting hooks come standard. They are placed on both sides of the tool, which help you to lower small machines into the cargo bay of ships to help finish the job without the need to switch attachments or machines.
Options to Meet Your Needs
With a wide range of clamshell grapples, they are fitted for many sizes of excavators and material handlers. The large capacity of material ranges from 1.25 yd3 (1 m3) to 8 yd3 (6.1 m3). Bolt-on cutting edge option for the shell will help enhance product life and work better for more abrasive materials. Bolt-on cutting edges offer scrapers to improve the dumping of sticky material for more difficult jobs.
Easy to Maintain
Improved dust seals help to lock out contaminants to keep your tool working longer. The shells are made from high-quality steel materials to withstand more jobs, as well as the bolt-on cutting edges. Ground level access to all grease points and removable panels help make grapple maintenance simple.
