Using field proven construction equipment componentry Doherty have developed a range of specialised grabs which provide an unprecedented range of movement and control to lift and accurately position a wide range of materials from drainage pipes to steel beams. By incorporating the latest quick coupler technology and modern electronic control systems a Doherty Grab can quickly transform an excavator or wheel loader into an effective, efficient and very safe manipulator.
DOHERTY BEAM GRABS (GBB SERIES)
Designed specifically for the safe handling of structural steel beams. The fully enclosed clamping unit provides and constant clamping speed and force – something that is impossible on a normal cylinder operated grapple – but is essential to permit precise positioning without damage or compromising safety.
Here is another example of a custom built Doherty Grab. This unit is designed for the removal and replacement of “stop logs” which are used to control water levels in many Australian reservoir systems. Featuring and parallel swing side shift, as well as full tilt and rotate capability this unit is designed to operate underwater. The specially designed clamping pads can be quickly reconfigured to enable the grab to position bridge beams as well as the concrete stop logs.
DOHERTY PIPE GRABS (GBP SERIES)
A wide range of pipe grabs can be combined with the unique Doherty Tilt/Rotate positioner. We can offer compact drainage pipe grabs for use in narrow trenches or multi clamp units which can handle a wide variety of diameters.
