This 2021 JLG EC520AJ is an articulating boom lift — a type of aerial work platform, sometimes referred to as a knuckle boom lift — designed to position workers and equipment at height in situations where obstacles or restricted access make a straight boom impractical. Articulating boom lifts achieve this by using a series of hinged boom sections that can fold and reach up and over obstructions, making them a common choice on construction sites and in industrial maintenance environments. JLG is a well-established manufacturer of aerial work platforms and material handling equipment, supplying machines to the construction, industrial, and infrastructure sectors worldwide.
This particular machine is powered entirely by electricity, using a 48-volt lithium-ion battery system configured as four 24-volt units in a 2S 2P arrangement. That setup allows the lift to operate with zero emissions and low noise, making it suitable for indoor use as well as outdoor work where emissions restrictions apply. Auxiliary power is provided at 12 volts DC. The serial number is C.
The machine offers a working height of 18 metres and a platform height of 16 metres, with a horizontal outreach of 10.65 metres. The up-and-over height — the clearance available when the boom is arched over an obstacle — is 7.30 metres. The jib articulates through a range of 145 degrees, and the platform rotates through 355 degrees in a non-continuous swing configuration. The unrestricted platform capacity is 250 kilograms.
For travel, the machine drives at up to 4.50 km/h in two-wheel drive and can handle gradients of up to 30 percent. Inside turning radius is 2.06 metres and outside turning radius is 4.78 metres, reflecting the machine's relatively compact footprint for its reach capability. Ground clearance stands at 0.42 metres. The tyres are non-marking 315/55 D20 units, and both front and rear tyres are reported at 100 percent remaining tread. Transport dimensions are 7.77 metres long by 2.35 metres wide by 2.27 metres high, and the machine weighs 8,055 kilograms. The machine holds CE Declaration of Conformity and is offered with a valid inspection and available warranty.
