Hitachi Sumitomo SCX900H - Reefer Stevedoring
This special Hitachi Sumitomo SCX900H of Reefer Stevedoring is used in the port of IJmuiden (NL). The crane is modified for it's material handling job.
The standard Hitachi Sumitomo SCX900 was converted for this; the A-frame, boom rotation point and the cabine are elevated. The name was changed to SCX900H, where the letter H stands for "harbour". The modification was done by Hitachi in Oosterhout (NL).
The crane is powered by a Mitsubishi 6D24-T, a watercooled 6-cylinder diesel engine with a power of 184 kW (250 hp). The diesel engine is powering multiple hydraulic pumps which are used to move the crane functions.
The counterweight of the crane was also modified, because the crane won't be transported frequently is the counterweight made out of a single piece. The counterweight weights approx. 30.4 tonnes and has a 4.27 meter tailswing.
The boom rotation point and A-frame were eleveated by approx. 3 meters. The cabin (not in height adjustable) was moved up about 6 meters. The main advantage of the elevated boom is the avoid collisions with boats. The elevated cabine gives the crane operator a proper view into the hold of the boat.
The undercarriage is 6.4 meters long and 4.9 meters wide.
Here is the crane in operation with a 34 meter long main boom, most probably the crane won't change the boom length a lot because the pendants can't be separated.
A tailor-made crane that is daily used to unload boats. In the background is a Hitachi CX500 with elevated cabin working, also of Reefer Stevedoring.
