Kobelco TK750FS
This sharp Kobelco TK750FS, of which I couldn't identify the owner, stood on a construction site in Auckland (NZ). It is a 75-tonne crawler crane with telescopic boom.
The undercarriage of the crane is 5.99 meters long and 4.83 meters wide. For the transport over the road is the width by hydraulics to be adjusted to 3.2 meters only.
The TK750FS is standard fitted with three hoist winches, the third hoist winch is positioned in front of the superstructure. This 11-tonne hoist winch is fitted with 26 mm hoist wire rope.
The other two 11-tonne hoist winches are fitted at the rear of the superstructure. The gray frame is used to lift the counterweights, this crane can be assembled and disassembled without use of an assist crane.
The three-part main boom has a 9.99 meter base length and extends three times to a maximum length of 30.1 meters. Here is the main boom extended to a length of 23.4 meters.
Here was the crane in operation with two hoist winches. It is not possible to attach a jib to the main boom.
The crane is powered by a Mitsubishi 6D24-TLE2A, an 11.9-liter 6-cylinder diesel engine with a power of 235 kW (320 hp). The diesel engine powers in total four hydraulic pumps.
Attached to the superstructure is a total of 17.2 tonnes of counterweight, the two-part counterweight has a 4.2 meter tailswing. A sharp crane!
