JLG 450AJ: what it is for

The JLG 450AJ is the best-known 16 m diesel articulating boom on site: 15.77 m working height, 7.62 m horizontal outreach and 250 kg platform capacity, unrestricted across the whole working envelope.

The articulating boom with a 1.24 m jib reaches up and over obstacles up to 7.30 m high and then places the platform precisely, for example over a roof or between steel structures. The turntable rotates 355° with zero tailswing, so it works close to walls and in narrow streets.

At 2.35 m wide and 6.5 t, on foam-filled rough-terrain tyres, it is an outdoor machine for construction, façades and industrial maintenance. The Deutz D2.9 36 kW engine meets EU Stage V.

Applications

Construction and steel structures
Façades, glazing and cladding
Roofs and gutters
Outdoor industrial maintenance
Electrical and HVAC installation at height

Transport and use

Transport: it weighs 6,495 kg and measures 6.58 × 2.35 × 2.27 m stowed, so it travels on a plant lorry or a machine trailer with ramps.

Where it works: it is designed for outdoor use and site terrain, with 45% gradeability and foam-filled tyres. Maximum ground pressure is 4.0 kg/cm²: on weak surfaces use load-spreading pads.

Operator: The operator must be properly trained to use mobile elevating work platforms (MEWPs): the employer is required to ensure this (Decree-Law 50/2005). The IPAF/PAL card is the most widely recognised training.

Inspections: Like any work equipment that lifts people, it needs mandatory periodic inspections (DL 50/2005), in addition to the manufacturer's preventive maintenance.

Mandatory periodic inspections (DL 50/2005)

JLG 450AJ fault codes

Search the code the machine shows to see what it means.

The Display Gauge on the ground control console shows DTCs from both the JLG Control System and the engine control system; the indicator lamp lights when a DTC is active and active faults are marked with an asterisk (*). Codes can also be read with the JLG Analyzer; the first two digits of a DTC are its flash code (e.g. fuel shutdown is reported as 0/0).

JLG 450AJ FAQ

What is the working height of the JLG 450AJ?

15.77 m working height, with the platform at 13.72 m. Maximum horizontal outreach is 7.62 m.

How much does the JLG 450AJ weigh?

6,495 kg in the European (CE) version. Stowed it is 6.58 m long, 2.35 m wide and 2.27 m high.

How many people does the JLG 450AJ carry?

Capacity is 250 kg across the whole envelope, which corresponds to 2 people with tools. Always check the machine's capacity plate.

Can the JLG 450AJ work indoors?

It is a diesel machine for outdoor use. For indoors, halls or finished floors, the electric E450AJ has practically the same working height, with zero emissions and non-marking tyres.

What is the difference between the 450AJ and the E450AJ?

The 450AJ is diesel, wider (2.35 m) and built for site terrain; the E450AJ is electric, narrower (1.75 m) and meant for indoors. The 450AJ has more capacity (250 kg vs 230 kg) and outreach (7.62 m vs 7.24 m).

How much does the JLG 450AJ cost?

The price is on request: it depends on the configuration (options, tyres, accessories) and delivery. Ask Trapézio de Prismas, the official JLG dealer in Portugal, for a quote.

Where can I find the JLG 450AJ manual?

The JLG 450AJ operation, service and parts manuals are in our JLG manuals library, by serial number. You can also request genuine parts from the same page.
