Verhoeven Bouw from Langeboom (NL) was using their sharp Sennebogen 643 R on a large construction site in Venlo (NL). It is a 40-tonne crane with telescopic boom that is installed on a crawler undercarriage. The crane's year of manufacture is 2008.

The width of the undercarriage can be adjusted by hydraulics from 4.5 meters to 3 meters, so that the crane can be transported as one unit.

The tracks are 5.39 meters long. The crane has an operational weight of approx. 37 tonnes.

The crane is powered by a Deutz TCD 2012 L06 diesel engine. The engine has a power of 135 kW (184 hp) and powers two hydraulic pumps, which are used to move the crane functions.

The counterweight weights 5.4 tonnes and has a 3.4 meter tailswing.

On top of the base section of the main boom is the hydraulic winch installed. The winch has a 4 tonne line pull and is using 14 mm hoist cable.

The main boom has a 9 meter base length and extends three times to a total length of 30 meters. The boom is here extended to a 16 meter length.

A very sharp and useful crane on the construction site!
