August 27, 2014 – Terex now offers an end-/top-mount cobra-style jib on its Hi-Ranger TL and LTM series aerial devices. Available on all 24 x 48-in. platforms, Terex says the jib is engineered with hydraulic articulation and extend, enabling operators to achieve a greater range of motion.
The cobra-style jib boasts a 16-in. profile, as well as a 600-lb platform capacity and 1000-lb maximum lift capacity, which can be realized with the work line extended farther from the basket shaft. Operators can rotate the jib thanks to an additional bearing at the bottom; this rotation offers linemen more versatility at the pole, says the company, and better accessibility between lines. This additional bearing rests on top of the Kingpost socket, which is attached to the jib and situated on the left of the levelling bracket so that it does not interfere with work. This jib also incorporates a poppet valve feature, which helps enhance safe work practices because it prevents the unit from damaging itself during operation. With the jib in stowed position, the truck’s boom can utilize its full range of motion, down to -40º.
