COVER STORY AROUND THE GLOBE

Doosan Portable Power at Intermat 2015 The Doosan Portable Power display at the Intermat 2015 Exhibition will include a number of important new products being launched at the show. They include rede- signed and Stage IIIA compliant G40-IIIA and G60-IIIA generators, alongside several new portable compressors including the Stage IIIA compliant 7/53, Stage IV compli- ant 12/154 and 12/254 and 7/125-10/110 Stage IIIB Dual Mode models.

wide choice of features to meet the needs of every rental and temporary power appli- cation. The output performance stability of the generators is ensured by an optimised powertrain featuring a combination of the new Stage IIIA engines and Leroy Somer AREP alternators. The new 7/53 portable compressor is a 36 kW Stage IIIA compliant replacement for the 7/51 model and has been redesigned to allow Doosan to keep this model in the Stage IIIA category, avoiding the need to transition to meet Stage IIIB regulations. The new features on the 7/53 portable compressor include forklift slots and a new bunded base option. The 7/53 compressor has an intuitive, simple key-start sequence, ideal for rental companies because of the reduced risk of machine abuse by untrained operators. The user-friendly control panel offers an open layout of instruments and warning indica- tors. A folding lift bail reduces the risk of theft by keeping the lifting eye within the compressor enclosure. A built-in toolbox compartment offers ample storage space.

Providing 40 kVA and 60 kVA prime pow- er, respectively, the G40-IIIA and G60-II- IA models are part of the new platform of generators from Doosan and share a com- mon design with the G80-IIIA to G200-IIIA models launched over the last two years. The Yanmar-powered G40-IIIA and John Deere-powered G60-IIIA generators will both be available with electronic speed regulation (optional on the G60-IIIA model) providing, in addition to stability and better load take-over capabilities, a flexible dual frequency 50/60Hz working mode (optional for both models). Like all Doosan generators, the new G40-IIIA and G60-IIIA models offer robust- ness and reliability, high performance and a

New Bobcat Telescopic Handlers at Intermat 2015 Linden Comansa launches in February 2015 her new 21LC335 flat-top tower crane, which is part of the LC2100 se- ries. This new tower crane is the result of the review of the 21LC290, a model that Linden Comansa produced with success since 2002, and which will be replaced by the 21LC335. Both cranes feature similar characteristics in terms of range (up to 74 m - 242.8 ft), maximum freestanding height (64.5 m - 212.9 ft) and versions depending on the maximum load capacity (12 and 18 t - 26,450 and 39,680 lb). The changes made as a result of this review have led to an important increase of load capacity with maximum reach- es under 70 m (229.7 ft). For example, the 21LC290 18t with a 50 m jib (164 ft) can load 5,300 kg (11,680 lb) at the end of the jib, while the new 21LC335 18t with same jib length loads up to 6,600 kg (14,550 lb), almost 25% more. With this same 50 m jib configuration, the 21LC290 moved the maximum load of 18 tons (39,680 lb) up to 16.3 m (53.5 ft), while the 21LC335 moves the maximum load up to 19.6 m (64.3 ft), 20% more. The tower sections of the 21LC335 are the S25, the same as the 21LC290, and the jib and counterjib sections are also the same as its predecessor. There have been modifications only on the cat head and the upper turntable, allowing customers who would like to convert their 21LC290 into a 21LC335 to do it by replacing these two elements and modifying the configuration of the counterweights. These changes have also allowed to simplify and shorten the assembly sequence of the 21LC335 in comparison to the 21LC290.

The 21LC335 crane comes standard with a Effi-Plus high speed hoist mechanism that reaches speeds of up to 150 m (492 ft) per minute, although there are other optional engines that can reach 228 m (748 ft) per

minute. Like the rest of Linden Comansa’s flat-top cranes, this new model includes the PowerLift system, that allows to improve the load diagram up to 10% with reduced speeds.
