Haegens Kraanverhuur from Elsendorp (NL) is operating this sharp Sennebogen 673 R, their largest telescopic crane on crawler chassis, that was used here on a cosntruciton site in Venlo (NL). It is a 70-tonne crane with year of manufacture 2014.
The undercarriage is 6.056 meters long and 4.8 meters wide. For the transport over the road is the undercarriage retracktable to 2.98 meters. Attached to the undercarriage is in total 8 tonnes of central ballast, on both sides a 4 tonne slab.
The crane is powered by a Cummins QSB 6.7 diesel engine with a power of 168 kW.
The 5-part counterweight exists out of a 825 kg base plate and four slabs with each 4.25 tonnes. The full counterweight weights 17.825 tonnes and has a 4.205 meter tailswing.
The crane is fitted with a 5-tonne hoist winch.
The 4-part main boom has an 11 meter base length and extends to a maximum length of 36 meters.
Optionally can the main boom be extended by a 8/15 meter long bi-fold swingaway jib, the jib can be mounted under a 0, 20 or 40 degree angle to the main boom.
On one side is the central ballast extended by a console where the superstructure counterweight can be erected on by the crane itself and then pulled up and attached to the superstructure by use of an hydraulic system.
A very sharp crane by Haegens!
