TOWER CRANES Ӏ SECTOR REPORT
j The design of this new rotating
part - jib, cathead and counter jib - as well as the mechanism, cabin and hydraulic unit platforms, optimises the transport of this model, which can be supplied by eight trucks or containers, Comansa says. The LCH300 incorporates
the Cube Cab (L or XL) with Split type air conditioning. The cabin platform, like the lifting and hydraulic unit platforms, can be transported in a single piece. Comansa says now, with the incorporation of the LCH300 hydraulic model, the luffing mechanism is optimised to offer even greater performance and an efficient assembly, as well as reduction of the radius when out of service.
Along with the new model,
Comansa launched Crane Mate, a digital fleet management and crane monitoring system. It provides real time technical
information, location, alerts, and crane productivity and maintenance parameters. It also makes it possible to
report and configure events and record machinery lease periods. All new Comansa tower cranes
orders after Bauma 2022 are being equipped with Crane Mate and the company is offering free trials, online tutorials and technical support for its clients.
DOUBLE TOPS Spanish tower crane manufacturer Jaso launched two new crane models at Bauma: the low-top J390 and the flat-top J235.12. The J390 low-top has a
maximum load of 24 tonnes and a tip load of 3.8 tonnes for a maximum outreach of 75 metres. Boom length can be increased
in five-metre sections. It has versatile load chart options, says Jaso, and its features include a 15.3-metre swing radius, lay flat

Jaso showed its J390 low top and J235.12 flat top at Bauma
counterweights and a maximum free standing height of 81.4 metres with a 2.16-metre tower system. The J235.12 flat-top crane has a maximum load of 12 tonnes and a tip load of 2.6-tonnes. It has a boom length of 30 to 65 metres, which can be increased in five-metre sections. It has a 14.9-metre swing radius, lay flat counterweights, 55.9-metre free standing height with a 1.75-metre tower system. Its lifting mechanism offers a maximum rate of 225 m/ min (65kW).
Both cranes are optimised for
transport/assembly and feature the energy efficient ECO Mode system to reduce the carbon footprint.
STANDING TALL Manitowoc had a large stand at Bauma 2022 which featured two new tower cranes: the MDT 159 topless, and the MR 229 luffing jib. The topless model was the latest addition in its Potain MDT City crane range. The six-tonne capacity MDT 159 fills the gap between the MDT 139 and MDT 189. It has a 60 metre maximum jib. The crane is suited to small- to mid-sized building projects of up to ten floors, says Potain, and it has been specially designed for tight
urban job sites, requiring just three containers to transport the crane’s full upper section. Assembly is aided by
Manitowoc’s Crane Control System (CCS) which is designed to increase the efficiency of communication between the crane and on-site staff. It also enables the lifting and distribution ropes to be fixed at ground level, reducing assembly work required in the air, says Potain. The MDT 159 has two
new trolley systems, one with permanent four falls and the other with an automatic reeving system. The DMP trolley requires only limited maintenance, while the permanent double reeving means no adjustment to the ropes is needed on site, Potain claims. This means that the crane’s maximum capacity of six tonnes is permanently available. The DMP trolley also offers 0.5
metre greater height under hook compared to the SM/DM Quick Lock alternative, Potain qualifies. The other trolley, the SM/DM Quick Lock, can automatically change reeving at the flick of a switch. This process is managed by the CCS. The Potain MDT 159 is one of the first models to come equipped f
