JLG 660SJ: what it is for
The JLG 660SJ is the 22 m diesel telescopic boom: 22.02 m working height and 17.40 m horizontal outreach, one of the longest in its class.
It has two capacities: 340 kg restricted (3 people, in a smaller envelope) and 250 kg unrestricted across the full reach. The 1.83 m jib with 130° articulation helps reach awkward points at the end of the boom.
4WD, oscillating axle and 45% gradeability. It is the machine for long straight-line reach: set-back façades, over fences, trenches or docks.
Applications
- Construction and steel structures
- Set-back façades and work over low obstacles
- Ports, docks and infrastructure
- Industrial installation
- Maintenance of halls and sheds

Transport and use
Transport: 12,528 kg and 10.01 × 2.48 × 2.58 m stowed: plant lorry.
Where it works: outdoors on site terrain with 4WD and 45% gradeability. Tailswing is 1.22 m: keep clear space behind the turntable.
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.
JLG 660SJ price
The price of a new JLG 660SJ is on request: it depends on the configuration (options, tyres, power, accessories), lead time and delivery location. Tell us what the machine is for and we will send a quote.
JLG 660SJ fault codes
Search the code the machine shows to see what it means.
The display gauge on the ground control panel shows engine run hours, fuel level and Diagnostic Trouble Codes (DTCs) from both the JLG Control System and the engine control system. DTCs can also be read with the JLG Analyzer; the first two digits of a DTC are its flash code.

What is the working height of the JLG 660SJ?
22.02 m working height (platform at 20.02 m) and 17.40 m horizontal outreach.
How many people does the JLG 660SJ carry?
Up to 340 kg (3 people) restricted, in a smaller envelope, or 250 kg (2 people) across the full reach. Always check the capacity plate.
How much does the JLG 660SJ weigh?

Telescopic 660SJ or articulating 600AJ?
The 660SJ gives more height and much more straight-line reach; the 600AJ goes up and over obstacles and has zero tailswing, which helps in tight spaces.
How much does the JLG 660SJ 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 660SJ manual?
The JLG 660SJ operation, service and parts manuals are in our JLG manuals library, by serial number. You can also request genuine parts from the same page.
