The Indian market of loaders and pick-n-carry cranes is passing through an interesting phase. Manufacturers are aggressively looking to add newer dimension to the product category, through carrying out engineering advancements along with introduction of newest product lines in the segment. This is both for general infrastructure applications, however, notably for precast engineering construction both in commercial and residential construction. P.P.Basistha took stock of the emerging advancements.
Growing requirements of precast building construction is driving to a good extent the newer engineering advancements of pick-n-carry cranes and introduction of new variants of telescopic loaders. Traditionally, loaders and pick-n-carry cranes have been used mainly for moving and lifting lighter loads, comprising construction materials and utilities, required at projects, within the job site limits. However, based on the newer application requirements of pre engineered buildings, featuring modular construction and in situ assembly of building sections, loaders and pick-n-carry cranes is presently passing through an extensive makeover to suit the newer application requirements. Value in the products, in its new origin features multiple attachments to lift varied parts and sections of the pre-engineered buildings. The newer equipment also incorporate newer safety features both to suit the onsite ground requirements and lifting requirements in pre-engineered building construction. Longer working heights through extended booms, for pre-engineered highrise construction is one of the other added value based features.
Pre cast is increasingly being preferred over in situ casting at various project sites. This has thrown up new demand for handling of precast components. TRX is best suited for such applications.
Mr. Raina continues, "Another launch, in this series of cranes, scheduled for this month is Escorts F17. It's a 17 Ton crane with a maximum lifting height of 21m. Besides other applications, it will be very useful for building construction sites. The back-to-back launch of F 20 & F 17 will give you an idea about the traction in the market for this family of cranes with highrise building construction sites is one of the target application areas.
Mr. Raina avers, "Continuing with our quest to incorporate advancement, we have made the new, F-20 more compact. It is the first crane in its category with front wheel drive which gives it a distinct advantage while travelling with load under all conditions. With a rated Capacity of 20T @1.5m it is the only Pick-n-carry crane that can lift 15T using the snatch block & winch. The travel speed for mobility & the ideal creep speed for load handling are the USPs of the crane."
The TRX cranes claim to deliver higher levels of safety as they have a special platform as compared to tractor platform in pick-n-carry cranes. The cranes are provided with outriggers for added stability. One of the prominent features of the crane to prevent toppling is ensured through design improvements by maintaining the center of gravity close to the ground with the right ground clearance. Load moment indicators are the added safety features of the cranes.
ECE will ensure support to the cranes, primarily by facilitating prompt parts availability through its sixty dealers with 180 outlets. Mr. Raina adds, "The emphasis would be to increase efficiency of the existing dealers by making them more robust."
He continues, "Safe load indicators are available on our all 'New Generation Cranes'. One of the major attributes of the cranes is that they have been 'overdesigned' as far as their lifting capacities are concerned, to ensure safe and stable operations even in steered / articulated condition. 2-3 highly productive attachments have also been introduced which make these cranes versatile, both for core, construction and general industrial usage."
ACE's 'New Generation' cranes comprise of SX Series for construction and industrial application. The cranes are available with 12-14-16 tons lifting capacities. The other offering in this segment includes, FX Series, also for infrastructure projects and industrial usage and are available in 15-20-23 tons capacity. ACE will launch higher capacity, 25 tons by April this year.
The third offering in the segment is F series wherein the company currently offers crane in 16 tons capacity.
Mr. Agarwal says, "To ensure the cranes deliver higher mobility, we fit them with commercial drivelines from Tata and Ashok Leyland. This makes them move at higher speeds of 40 kmph plus on roads, enabling them to operate between clusters of job sites."
ACE has also improvised its conventional, mainstay pick-n-carry cranes. ACE manufactures its 'Hydra' series of pick-n-carry cranes from 9 to 20 tons. Explaining the rationale behind the advancements being carried out in the Hydra series cranes when demand for new generation cranes is improving owing to their improved safety features, Mr. Agarwal says, "The conventional pick-n-carry cranes still continue to command 70% of the demand in comparison to the new generation mobile cranes."
The improvised cranes come with better ground clearance, improved fuel efficiency and options of safe load indicators. Both the existing and new generation cranes are supported by all India network of dealers and area offices operating out of 100 Locations and supported by 15 Area / regional offices and a dedicated product support division based at Faridabad.
Mr. Agarwal says, "As the population of our new and conventional pick-n-carry increase, we will add more dealers and service locations, so as to be closer to customers." The company has a full-fledged dedicated training center at Faridabad in Haryana for providing operator and preventive maintenance training."
Usage OrientationPrefabricated engineering construction in building requires lifting and moving with loads of varied capacities within the site limits. Further, there are many other jobs the cranes are required to do. For example, the cranes may require to move with the loads while working within the fabrication yards. The usage also involves taking the loads or the building sections from the yards to the construction sites. Further, there are also requirements to lift the loads at heights within a compact area. This is when the building construction, notably highrise is taking place within the city. All the concerned jobs require lighter yard cranes with higher levels of mobility. The booms are required to be maneuverable as well in many cases supported by the attachments.
With all the pre engineered building construction jobs becoming extremely time bound, at par with other infrastructure jobs, optimum usage of the pick-n-carry cranes is required. Most importantly, the cranes are also needed to work safely and are required to be designed featuring compactness, to be suitable while working at compressed construction locations, notably if the work is of building construction projects taking place in clusters.
'Load all' telescopic handler is being manufactured at JCB India's plant at Ballabgarh in Haryana. Currently, the company is manufacturing two models of the telescopic handlers, 530-70, with 3 tons lifting capacities and 7 meters working height and 530-110, 3 tons with 11 meters working height in India. The company is also offering higher capacity, 540-170, 4 tons, 17 meters working height from its U.K facility.
Mr. Singh elaborates, "We have added adequate value to the new machines through various new attachments, most of these are indigenized. Prominent among the attachments are general bucket, hooks, man platform, and industrial grappler. The multiple attachments make the machines suitable for usage for varied nature of general infrastructure and industrial projects, wide scope of application with the attachments, make them preferable for rental and corporate buyers in onstruction and in agricultural logistics."
Apart from adding value through attachments, Mr. Singh explains, "We have engineered the equipment to deliver total lifecycle costs by making them cost competitive. Cost competitiveness to own and operate the telehandlers is based on the commonality factor with our JCB backhoe loaders. This in terms of the similar drivelines as in the backhoe loaders, 76 hp, fuel efficient; 'Ecomaxx' engines and various other common components. Commonality of parts enables our dealers to service the new machines with ease." JCB has introduced separate industrial vertical to service the new 'Load all' telehandlers and skid steer loaders with its existing sixty dealers.
