Green Regulation Compliance
This approach, the company noted, reduces complexity, improves serviceability and importantly avoids a loss of engine power compared with machines built under Tier 4 Interim or earlier emissions standards.
Cost Considerations
Upfront purchase price— New compliant engines and exhaust systems raised development costs due to the added complexity of SCR, DOC, DPF and EGR systems. If the experience with earlier Stage IIIB and Tier 4 Interim standards is any indication, Tier 4 Final engines will come at a higher price for crane operators.
Operating and maintenance impacts— Tier 4 Final engines require additional maintenance, including periodic checks of SCR health, replenishing of DEF, regeneration and cleaning of DPF system and possibly more frequent servicing of exhaust components. This can lead to higher operating costs compared to older machines without these systems.
Productivity tradeoffs— When heavier engine components and exhaust systems and DEF tanks add mass to cranes, OEMs have responded by shifting counterweights or re-rating certain transport configurations. In other cases, the chassis itself had to be redesigned. All those factors can affect the cost of transport logistics, sometimes requiring additional trailers or axles, and may add to on-site rigging time.
Disposal and resale— As stricter engine emissions standards go into effect, older non-compliant cranes may be harder to resell or may command lower values, especially in regions that now strictly require Tier 4 Final compliance. Moreover, some users will end up retrofitting used cranes or trading them in, further diminishing residual values in the used crane market.
Eco-Friendly Crane Outlook
Despite these cost concerns and changes in regulatory enforcement activity, manufacturers are moving ahead with product development to meet the latest engine emissions requirements.
While fully electric and hybrid cranes may still face challenges in heavy-lift capacity or jobsite power infrastructure, there is no doubt that zero- and near-zero emissions cranes are here because their long-term appeal for reducing exhaust and noise emissions aligns with fleet sustainability goals.
There is not an easy bolt-on solution as a path to Tier 4 Final compliance.
One example is the Tadano all-electric EVOLT eGR-1000XLL-1 rough terrain model. The 100-ton model offers up to seven hours of lifting or up to five hours of lifting plus 5.5 miles of jobsite travel with its on-board battery pack.
Liebherr E Drive cranes are offered in a range of models that can be powered by electricity for crane operations. The 175- ton LTM 1150-5.4E all-terrain has a hybrid drive that allows for electrically powered crane movements. With its integrated battery, the crane can work autonomously for up to four hours without a power connection or use an electric grid connection on the jobsite.
The manufacturer’ s Hybrid Power Concept, which enables operation with site power is offered on the MK 140-5.1E mobile construction crane. The five-axle model has 17,637-pound maximum lifting capacity. Additionally, the manufacturer offers the LTC 1050-3.1E. With an electric motor in addition to its conventional power unit, the 50-ton crane’ s movements can be powered using electricity from the site.
At Manitowoc, the manufacturer’ s Grove and Potain product lines include ongoing developments in electrified handling equipment. At SANY America, there is an aggressive push into electric heavy cranes. With published specs for crawler and RT models, and larger electric lattice crawler concepts globally, SANY has electric truck crane and lattice crawler models intended for markets including North America.
In ports, industrial facilities and other areas with on-site power infrastructure as well, hybrid diesel and battery cranes that reduce emissions have already been deployed.
Decarbonization involves real costs, real engineering trade-offs and a new risk profile for owners and operators. But it has also catalyzed innovation. Today in the future, demand for clean cranes is likely to accelerate because companies that act early may benefit from advantages in reputation, compliance and fleet modernization.
Liebherr electric E Drive cranes allow for electrically powered crane movements and the use of a grid connection on job sites. Among the range of models offered by the manufacturer is the LTC 1050-3.1E rough terrain. Also available are all-terrain and mobile construction cranes that use the manufacturer’ s hybrid systems.
