The New Kobleco CKE2500-2 shows its redesigned counterweight system with one size interchangeable slabs.

The key benefits of the new model are its improved lifting capability, thanks to a number of structural changes and 10 percent more counterweight, which has resulted in a machine with a 15 percent increased load moment of 1,177tonne/metres.

The increased capacity flows through most of the load chart and thanks to weight savings in the undercarriage and other areas, comes without increases in the operating or transport weight. In fact the new model is easier to move than the existing model.

The changes include:
- A modified superstructure frame with a higher capacity slew ring.
-.A new counterweight system, increased from 100 tonnes to 110 tonnes with identical universal slabs.
- A reduced transport width, now 3.4 metres compared to 3.5m metres on the current model. The gain comes without the need for a swing away cab.
- Longer crawler frames with a considerably increased square foot print.
- Lighter weight crawler frames, reduced from 23.5 tonnes to 20.7 tonnes.
- A new, stronger, luffing jib.
- The Introduction of a tapered jib section, so that the luffing jib can also be used for long boom configuration, increasing versatility;
- Greatly increased boom and jib combinations, the maximum ‘long’ main boom length is 91.4metres. The maximum standard crane boom plus fixed jib is 76 + 30 metres, and the maximum luffing jib combination is 61+61metres, with a supplementary mid-support strut.
-A new engine, with five percent more power complies with stage 3 emission standards. While refinements have been made to the hydraulic system, including independent winch-pump drives, and ‘super-fine’ filtration with 1,000-hour service intervals.

The new model replaces a popular class leading product, with over 200 units of the CKE2500, CK2500 and related models having been sold since its introduction in 2000.
