JLG will unveil a 185ft self-propelled boom lift – the new 1850SJ – at Conexpo next week, topping the current largest lift, the Genie SX180, by almost two metres with a platform height of 185.7ft and a working height of 58.5 metres.
The 1850SJ Cherry Picker features an all-new chassis with X type axle configuration. Overall stowed width is 2.49 metres, which extends to around five metres in working mode, extension takes around 60 seconds.
The lift/boom configuration comprises a five section telescopic boom and a two section 6.1 metre long telescopic articulating jib. Maximum outreach is 24.4 metres with a platform capacity of 227kg, maximum platform capacity is 454kg good for up to 21 metres of outreach at a height of around 11 metres. An LCD screen at the platform controls shows the machine status and platform position within the work envelope.
Unlike Genie, JLG decided against incorporating any jib rotation function into the 1850SJ (The SX180 offers 30 degrees either side of centre), preferring to keep it simpler, but more to do with the fact that its jib is considerably longer and combined with the higher capacity would impose substantial twisting forces on the main boom. The jib does however fold back for transport. Platform rotation is 180 degrees.
The unit weighs 27 tonnes and when fully stowed can be transported on a regular truck without the need for oversize permits. Overall stowed length is just under 14.6 metres, while the overall height is just over three metres. The machinery covers follow JLG’s latest thinking and are made of steel, rather than fibreglass.
This new cherry picker will be the tallest self-propelled boom available to hire and will be aimed at applications such as petrochemical plants and shipyards.
