The cylinders feature internal hydraulic cushioning that slows the grapple at the very end of cylinder
movement during both opening and closing. This minimizes the “slamming” effect when opening and
closing the grapple at high speed.

The latest design technology was used for the development and preliminary testing of each grapple
component. All critical parts are made from high-strength steel to ensure trouble-free material handling,
even in the worst conditions. |
 |
The quick-attach feature of Grabtec grapples requires that custom mounting kits be welded to the
bucket. All mounting kits are designed so that the bucket is protected from the forces that are exerted
on it by the grapple cylinders. Additionally, the support plate is adjustable. This ensures that the retaining
pins that secure the grapple to the mount can be easily removed. |

Grapple hoses come equipped with nylon protective sleeve. |
 |
All pivot pins feature zero-maintenance bushings and wiper seals. No grease is required anywhere on
the grapple. The pins are hardened steel with chrome plating and have generous tapers for easy installation. |
 |
The hook and retaining pins are hardened, chrome-plated steel to resist corrosion. |
 |
Hydraulic hoses for the cylinders are supplied, as well as two tees. Typically the backhoe’s auxiliary
hydraulic spool supplies the tees for grapple operation. |
 |
A closing gap that is close to the cutting edge is typical with most buckets. |
 |
The wide space between the grapple and the bucket allows high-capacity handling of loose material
This combined with the wide opening of the grapple means it is much more effective at handling material
than rake or scrap grapples, which tend to squeeze objects rather than pull them into the bucket. |
