Caterpillar
The Cat G130B Contractors’ Grapple is a heavy-duty, durably constructed tool designed for structural demolition, material handling and utility application, such as sorting and loading rock, scrap and construction debris. The Cat G130B works ideally with a range of models in the Caterpillar medium-hydraulic-excavator lineup. The Cat G130B uses a two-over-three tine configuration that allows the three tines on the slightly curved lower jaw to sink easily into scrap piles, while a pair of tines on the interlocking upper jaw exerts ample hydraulic power to retain material securely on the large working surfaces of the jaws. Abrasion-resistant AR 400 steel, used for tine tips, wear plates and wrappers assures durability in the harshest environments. The flush design, coupled with the precise curvature of the lower jaw, assures that material slides out with no obstruction when the grapple dumps. www.cat.com

Ditch Witch
The Aggressive Talon Rock Bit is a multi-use bit manufactured for HDD applications in a variety of soil conditions, including sandstone, shale and chunk rock. The bit’s thread-on shank provides even greater reliability and durability in tough digging conditions. The Aggressive Talon Rock Bit features four replaceable carbide-tipped cutting teeth in front of the tool that enable it to operate more smoothly with less drill pipe chatter. The angle of the cutting teeth enables it to more effectively carve into rock. Carbide buttons in the abrasion-resistant, steel-bit body reduce wear when working in tough conditions. 800.654.6481, www.ditchwitch.com
