of the biggest fleets in the
world, taking on the toughest and most complex jobs, it’s vital. Increasingly, lead contractors and project owners want to track their emissions under Scope 3 of the Greenhouse Gas Protocols. Scope 1 of the protocols covers a company or projects direct emissions; Scope 2 covers indirect emissions, from energy use, for example; and Scope 3 covers those from the supply chain. That includes fuel use by equipment used during construction. Mammoet has developed
its own system to meet these requirements, which it has given the codename DAISY. This plugs into the embedded systems on its SPMTs and cranes, allowing for real time, location based, monitoring of CO2, NOx, and NH3, or ammonia, which contribute to both global warming and local pollution. Data is shared over mobile networks, and presented in a web interface, allowing regulators and project owners to check on emissions as needed. Insights from the system can then be used to identify measures to cutting emissions, whether that is by changing operator instructions to reduce idling, or by employing non-emitting equipment such as Mammoet’s electric SPMTs. Mammoet has deployed the
system first on a fleet of cranes operating in the Netherlands, and intends to roll it out across its fleet through 2023. Jacques Stoof, head of innovation at Mammoet, commented: “DAISY will be the most advanced system to accurately report CO2, NOx and NH3 emissions at the equipment level at the operating location, improving on the generic approach the industry is currently using. “Based on the actual reported emissions, clients will be given the option to choose a more sustainable, less emitting

LICCON3 is the
third generation of Liebherr’s crane control system
fuel type in order to minimise their emissions footprint during construction”. Mathias Hoogstra, head of sustainability at Mammoet, added: “With this significant step, we are able to assist clients and empower our own reduction ambitions. DAISY’s factual emissions data allows us to take smarter decisions, reducing our footprint in a more efficient manner.”
A 250T TAXI Taxi operation is key for most buyers of all terrain cranes. The big three manufacturers each make use of sophisticated control systems, like LICCON3 and Manitowoc’s CCS, to optimise performance in constricted positions or with limited counterweight on board. Tadano’s system is IC-1 Plus, and this, along with a highly customisable counterweight configuration, enabled it to pitch its latest all terrain, the fixe-axle 250t AC 5.250-2, as a taxi crane. The new crane was designed
by the new team at Tadano’s Lauf (formerly Faun) and Zweibrucken (Demag) production facilities. It achieves, Tadano says, lifting
capacities ten or more percent higher across the load chart, and up to 30 percent higher in some configurations, compared to previous best values in this class. The crane features a 70m main boom, with a maximum system length, including extensions, of 112m. With the main boom fully extended, it can lift as much 14.5t to radii up to 24m: enough to lift the main structure of many tower cranes, or to place heavy rooftop machinery. The crane can carry a three-
sheave hook block for lifting loads of up to 67.3t or a 5.8m heavy-lift runner on board while remaining within a 12-tonne axle load configuration. In the UK, and other markets where cranes can run with axle loads of 16.5t, the crane can bring 20t of counterweight on the road to site. The crane’s full counterweight comes to 80t. Making use of this will always require a support vehicle, but once this arrives on site, placing the counterweight has been made as easy as possible. The crane can pick up its total counterweight of 80t in three lifts: 49.6t with a full 360° radius of up to 6.2m followed by two lifts of
