SuperGrip-S

SuperGrip-S

The SuperGrip-S is a heavily reinforced log grapple that can handle the toughest forwarding jobs. It’s also ideal for mounting on an excavator.

In designing the SuperGrip-S, we’ve incorporated all our knowledge about durability and ruggedness to give contractors looking for a sturdy grapple exactly what they need. Just like its fellow SuperGrip grapples, the SuperGrip-S is used in forests around the world. It’s especially popular in North America, South America, and Australia, which have the heaviest tree species and the most challenging conditions.

Grapples that grow to meet customer requirements

A few years after the launch of the SuperGrip std, a number of customers got in touch with the same message: the grapple is fantastic, but we’re wearing it out. Common to all was that they operated under really tough conditions, often far beyond the borders of Europe, and not infrequently using excavators. After some discussion about the exact specifications and unanimous agreement to increased weight, Hultdins was able to introduce the SuperGrip-S at the end of the 1990s.

SG360S – the indestructible log grapple

The first S-grapples were reinforced by hand, but the early 2000s saw the introduction of the robot-welded SG260S and SG360S models. These quite simply marked the end of an era where grapples failed during normal use. And this applies to almost any use. Even today, we are quietly confident that there are no grapples in the 260 and 360 size classes stronger than the SuperGrip-S. Well, other than the ultra-reinforced SuperGrip-RS of course.

All-round durability improvements

The S after SuperGrip stands for strong, indicating that we’ve used thicker plates throughout, from the frame to the tips of the arms. We have, however, retained the popular geometry, as operating an S-grapple should feel like operating a SuperGrip std, other than that it can take more of a beating.

The grapple that never fails

As cranes get successively stronger and productivity is continually increased, so has S-grapple use steadily grown. In the early 2000s, the SuperGrip-S was the answer to extreme assignments, whereas today these models are sometimes sold for regular forwarding in Sweden too. As a result, downtime due to grapple failure is little more than a distant memory.

Every component individually selected

The SG360S is the tank of the forest. When nothing else can cope, this grapple has proven itself the ultimate solution on countless occasions. A very important factor if a grapple is to cope with heavy loads is that the pins are generously sized. The larger the pin diameter, the larger the area over which the force is spread. The SG360S has grapple arm pins with a diameter of 80 mm, easily the largest in its class. That these are expander pins with an internal taper is a given – it is, after all, a Hultdins!
