Since 1971, Kinshofer GmbH has been a major manufacturer of high-quality attachments for truck-mounted cranes and it is now on the way to becoming one of the leading excavator attachment producers worldwide, too. In the last two decades, KINSHOFER has become more and more popular for the re-handling business, producing large orange peel grabs (P-Series) for excavators with an operating weight of up to 120 tonnes and re-handling clamshell buckets (C-Series) for excavators and carriers with an operating weight from 18 tonnes of up to 100 tonnes.
The durable KINSHOFER re-handling clamshell buckets of the C-Series have been developed especially for the loading and unloading of bulk materials in large amounts. The widely spaced pivots and the flat closing curve provide maximum volume and the ground surface is protected when discharging from e. g. boat or train carriages. The two shells are driven by sturdy hydraulic cylinders.
The C-series grabs are available for excavators with 18t up to 100t operating weight. The smaller versions up to 65t are equipped with two vertical cylinders, the C100VHD up to 100t with four cylinders. The shells are very robust to withstand highly abrasive materials and the integrated endless rotation guarantees the precise positioning of the grab.
An alternative to the clamshell buckets is the KINSHOFER orange peel grab P-series. Sizes range from the smallest P22V for excavators from 16 tonnes operating weight up to the huge P120VHD with a staggering volume of 3,500 litres in the largest variant. Different shell designs — narrow or wide, half or fully closing tines — allow to match the grab to the task.
These heavy duty, sturdy grabs are often used to handle scrap, waste or rocks. As the C-series, the orange peel grabs are equipped with a robust 360° rotation. Accurate fittings eliminate tine distortion, the end stops for closing and opening are especially solid. Bolts are reinforced and have a large bearing surface. The hydraulic cylinders that operate the arms are protected by replaceable piston rod protections.
All KINSHOFER’s grabs can be used on- and off-shore — in the end it does not really matter where the carrier machine is located and what size it is. As KINSHOFER also has a department for special constructions, every attachment can be adjusted or designed from scratch.
