PICK & CARRY CRANES Ӏ SECTOR REPORT
“It is the endless flexibility of
the Valla mini crane in helping us simplifying lifts and carrying them out safely that we appreciated,” says KC director Kevin Hill. “It can be lifting pipes or EV charging units, or supporting machinery maintenance and whole factory moves.” Valla is expanding in the sector.
The company has invested in the development and production of four new heavy pick and carry cranes in its V-range. The cranes are electric battery
powered, with wireless remote control, and with options for safe working loads of 35tm 40t, 45t and 50t. They can be supplied with long and short booms, and with or without sit-in cabs. Available attachments include a winch, a manual stubby fly jib, a hydraulic luffing fly jib, and a self-levelling fork attachment.
DUAL FUNCTIONS Many other mini cranes have pick and carry capabilities. Often these are incidental to their primary function as glazing robots or mini
turret designed to provide smooth, millimetre-precise positioning of the load. The largest model in the
Marchetti
Autogru’s new electric City Crane, the Trio 0e, can travel with 5.5t on the hook
crawlers. For example, Jekko’s MPK06.2 and MPK10.2 are marketed as part of its mini-picker and glass robot range. But, to quote Jekko’s marketing material: ‘…in a few minutes they transform into a compact pick and carry crane’. The machines have been
redesigned and the new designs were launched at this year’s Bauma. They are battery operated, compact, fit a standard single door, and can be specified with white, non-marking tyres if required. The ballast is in easily removable modules to make it easier to transport, for example on elevators. They have a mobile
family, the two tonne-capacity MPK20.2, also launched at Bauma, has undergone a more complete redesign and is the opposite of the previous models: instead of being a mini-picker that can become a pick and carry it is marketed as a pick and carry that can become a mini-picker. It is a two-tonne pick and carry crane that, with the installation of the independent glass manipulator JVM800, transforms into a glass robot. It can work in hook or winch
mode, has an intuitive control system with a five-inch IP66 onboard touchscreen display, radio remote control and tiller bar, and a new ‘steer by wire’ driving system that allows handling in the tightest spaces. The new Jekko machines can have, as an option, the J-Link Advanced Remote Monitoring System which allows real-time fleet management, machine optimisation, and predictive
SARENS PAPUA NEW GUINEA TAKES DELIVERY OF 25 TONNE FRANNA MAC 25
As an example of the geographical spread of Terex’s Franna brand, back in January this year Sarens Papua New Guinea took delivery of a 25 tonne Mac 25 articulated pick and carry crane for use in the mining, oil and gas, construction, and industrial sectors. The Mac 25 is a tried and tested Franna design with an 18 metre four-section boom and a short three metre jib that, together, give a maximum tip height of 21.5 metres. Overall weight is just under 24 tonnes. A key feature is the dynamic LMI (load moment indicator) system. It addresses the issue that is inherent to all articulated pick and carry
designs – where cornering on a slope with a load can bring instability (see the main copy for more details.) Franna’s solution is not new – it was first released in 2013 – but its patented system underpins the electronic control and remains a pillar of safety. The system offers real-time calculation of rated capacity. It takes into account boom configuration as well as chassis articulation and pitch and roll to give continual assessment of structural limitations, forward stability, and side stability. Finer measurement of articulation pitch and roll angles now give increased resolution of rated capacity, allowing improved machine capability compared to previous generations of the system. On undulating terrain the rated capacity is updated continually, providing instantaneous information on the percentage utilisation of the machine in terms of the available capacity. When operating on a side slope operators are no longer required to manually calculate a reduction of rated capacity; the Franna Dynamic LMI does that for them. A superlift upgrade is available on the MAC25-5 as an option. It works in tandem with the existing MAC25-5 counterweight, adding a low-slung additional counterweight piece to the rear of the machine to increase the rated capacity up to 30%.
