JLG’s ‘green’ crawler booms

With working heights ranging from 14metres to 23metres, the five JLG Compact Crawler Booms feature a tracked wheel carriage and a narrow chassis for access through gates, yards, standard doorways and public buildings. The compact crawler booms are said to be low weight units drawing on an environmentally friendly combination of electric and combustion power for efficient energy use.

The 1500SJ is said by manufacturers JLG to be the first straight boom lift that elevates operators to 45.72metres and requires only a weight permit for transport. The telescoping jib, which can extend up to 7.62metres, provides flexibility and what is said to be “exceptional” horizontal and vertical reach. As with all JLG Ultra Booms, the 1500SJ delivers dual 450kg/230kg capacity and three steering modes. Among its features is an LCD display communications machine to assist operators in positioning the plat

JLG’s diesel-powered 510AJ boom lift, with a working height of 17.81metres, is said by the American firm to be specifically designed and produced for the European market, providing high level access with a spacious work platform. The machine is said to be ideal for use in confined locations and can be set up and re-positioned quickly in narrow, compact spaces. Other work can carry on around it relatively undisturbed due to low sound levels while operating.

Unveiled as a prototype at SAIE, Italy in October 2010, the compact 340AJ boom lift can cope with grades and break-over angles up to 45° allowing it to drive on slopes and up ramps. Built to a working height of 12.35metres and with a horizontal outreach of 6.07metres, the 340AJ is said by JLG to meet demands for a broad range of applications. The jib extends to 1.2metres with near vertical operation. When ground conditions get tough, proper off-road performance is ensured by the standard oscillating axle an
