The manufacturers and the distributors of the equipment are providing requisite product support. P.P Basistha takes a look at the newer solutions offered by the manufacturers across segments.
Skid Steer Loaders Deliver on Versatility
Owing to their compact design feature and maneuverability, skid steer loaders can easily be operated when working between pillars to clear debris. This could be in case of underground parking lots or underground metro stations. Being lighter, and compact, the skid steer loaders can be lifted easily with the help of a mobile telescopic crane and can be deployed on elevated metro or high rise construction to undertake material handling functions. The equipment, supported by their attachments can also help towards maintenance of the projects following their completion. This could be changing the landscaping. Other advantages of skid steer loaders attachments are solid waste management, road sweeper, grading and compaction of land for road construction in compressed space. This could be in case of streets or narrow roads within and outside the city limits.
He says, "JCB has designed wide range of attachments for its skid steer range such as Sweeper Collectors, Industrial Fork, Grapple Muck Fork, and Snow Blower etc. The loaders are fully compatible to work with our own attachments and the attachments from other vendors as well."
JCB 135 and 155 are manufactured at the company's flagship Ballabgarh facility in Haryana. Mr. Singh added, "A JCB skid steer is safe, economical and highly productive. With an average of 60% better visibility, with entry and exit from the left side of the machine, the machine has been designed to reduce the operator fatigue and ensure safety at all times. Pressure sealed cab and low effort controls are some of the ergonomically designed features to ensure operator comfort."
Value in ConcretingCatering to the requirements of urban infrastructure projects involving concrete roads, bridge and highrise requiring pumping of concrete at higher rates, equipment manufacturers are offering varied solutions backed by adequate product support.
According to him, the concrete batch mix plants are also suitable for concrete road projects as they can deliver concrete on rigid dump trucks without formation of lumps. Schwing Stetter manufactures CP18, CP30, M1T, M1.25T, M.2.25T, and M2.5 T compact and mobile concrete batch mix plants. The plants can batch concrete between 60-100 cum/hr.
Mr. Sakthikumar says, "For urban highrise construction, we offer SP 2800, SP 2509, SP 3000, SP 3500, SP 4800, and SP 8000 stationery concrete pumps. SP 8800 comes with almost 1km boom length. SP 8000 heavy duty concrete pump has the distinction of being used for pumping concrete at Petronas Towers, Malaysia, one of the world's tallest buildings. One of our unique solutions is mechanized boom placers for distribution of concrete. This is ideal for distribution of concrete on top of the highrise buildings measuring 200 meters." Schwing Stetter India possess dedicated designing and product support engineering personnel for setting and operating the stationary concrete pumps working for highrise projects.
He adds, "We have carried out advancements in our stationery pumps by adding features for human and machine safety like Hopper Grill, high oil temperature, low engine oil pressure etc. Ergonic Graphic Display systems have also been added which displays key operating parameters of the concrete pump like discharge rate, no. of strokes, fuel level, engine rpm etc."
According to Mr. Gabri, "Through our advanced technical attributes in stationery concrete pumps, these can deliver concrete at higher heights in efficient and safe manner. However, the pumps along with the stationary placing booms have to be provided with appropriate technical support. When pumping high grade of concrete, choking of the pipelines can easily occur hindering optimum discharge of concrete. To avoid this, the pipelines are required to be properly routed and needs to be backed with proper cleaning methods. To ensure that the concrete gets pumped without any hindrance, the layouts of the pumps and the pipelines have to be appropriate as well. We provide all the requisite technical support as above for optimum utilization of the pumps."
Material Handling AdvancementsHigh rise construction projects in India with 150-200 meters and above are coming up in metropolitan cities with severe space constrains. Many of the new buildings are coming up in areas with clusters of other highrise construction at very close vicinity. For this, luffing tower cranes are one of the new solutions in India to assist the projects.
He explains, "The luffing jibs can be raised for the wind to free flow without causing damage to the crane structure or the jib during the site holidays. By allowing the wind to free flow, pressure on the masts and jib of the crane is greatly minimized. High wind pressure is extremely prevalent in Delhi-NCR, Northern Indian region, and also in sea shore areas. This can act as a lateral force which can pass on to the structure of the construction project consequently effect the strength and life of the building. However, with luffing feature, allowing the wind to free flow, the pressure is extensively discounted."
Everest has commissioned 2 units of 10 tons SYM cranes to Lodha Group which are working for construction of 220 meters high, 65 storied buildings. The SYM cranes come with 43 meters freestanding height as compared to 33-36meters of conventional tower cranes. Another 4 units Luffing cranes of 10t & 8t are working with Capacite Infra Projects Ltd in Parel, Mumbai for 280m height building.
Everest Engineering, exclusively distributes FineHope and SYM flattop and electric luffing cranes in India. SYM and FineHope cranes are equipped with electronic safety system, speed control, etc. Fine Hope tower cranes are available in 32-200 tons, and SYM luffing tower cranes in 8-32 tons. Other products distributed by Everest Engineering in India include GJJ mast climbers, Passenger hoists and tower crane "Anti collision systems".
Value in urban infrastructure projects is claimed to be offered by JCB's new 'Load all' telescopic handler. Mr. Jasmeet Singh, JCB India says, "JCB Loadall comes with variety of attachments which makes the machine more versatile. The widely used attachments are General Purpose Shovel, Heavy Duty Forks, Bucket with Grab, Crane Hook - Fork Mounted, Grain Bucket, Power Grab, Man Platform and Drum Handlers.
Telehandlers have the advantage of placing and lifting loads at height along with the added capability of forward reach. This makes the machine effective in stacking, lifting and placing operations of heavy loads in a safe and productive manner.
Telehandlers have only recently made their way into the Indian Market as compared to the other traditional material handling products. Since this is niche segment at the moment so the market size is quite limited. At JCB, we are already manufacturing Telehandlers in India. These include a 7m machine, the 530-70 and an 11m machine, the 530-110 at the moment, additionally we also offer a 17m machine which is the 540-170 for high lift and reach applications which are imported from UK.

The product range is competitive in terms of price, durability and reliability. We always ensure minimal operating costs to the end user," says Mr. Jasmeet Singh, JCB India.
Highrise construction in metro cities require below ground free level for vehicle parking purposes. Hydraulic rock breakers are being extensively used to break the rock boulders at the ground level prior to the foundation. The other key applications include digging of road surface for laying pipelines and other utilities. The equipment are extensively used in controlled demolition for existing houses and other infrastructure projects to create new infrastructure in its place.
Targeting the growing application of hydraulic rock breakers in urban infrastructure projects, Doosan India is offering its 'economy' and 'premium' range of breakers of 2-5 tons base equipment of skid steer loaders and BHL, Mini excavators. "Bobcat sells premium range of breakers is almost a price difference of 40-50% higher between two ranges of breakers suitable for myriad applications in crushing. For higher volumes applications, the 'premium' range of breakers is more suitable. One of the prominent features of Bobcat is designed for ruggedness and highly reliable" says, Mr. Manjunath, Doosan Infracore.
He continues, "Combined with our improved FXJ and FXP series, we offer wide range of breakers that can be mounted on base excavator carriers 1-100 tons providing at least 20-30% higher level of rock breaking. The box frame design of our breakers achieves total performance and lower sound level. Lesser bolts and nuts design also makes scheduled maintenance quicker. One of the prominent features of the FXJ series of breakers is that they are thermal resistant that makes them suitable to work in a temperature above 30 degree, making them ideal for Indian conditions."
