JLG 860SJ Boom Lift Overturns at Sunrise Beach, Injuring Worker

30 Second Takeaway
A man was injured on Wednesday, July 29, when an 86-foot JLG 860SJ boom lift overturned at a residential property near Sunrise Beach, Missouri. He reportedly fell about six metres onto a dock ramp and was airlifted to hospital; his condition was not known in the available reports. The lift was positioned on built-up ground near a slope, but the cause of the overturn has not been established. Emergency crews also responded to a fuel leak from the machine, which was contained with assistance from the rental company.

Incident Overview
Sunrise Beach, Missouri, United States
The incident occurred at a residential property on Old English Point. The JLG 860SJ, an 86-foot telescopic boom lift reported to be from the EquipmentShare fleet, overturned near a slope while work was underway on the building.
Firefighters found the injured man on a dock ramp after a fall of approximately six metres. Access to him was limited by the position of the overturned lift, and a helicopter was requested to transport him to hospital.
What Happened
Based on information available at the time of publication:
A JLG 860SJ boom lift was being used for work on a residential building.
The machine was reportedly positioned on built-up ground near the edge of a slope.
The lift overturned, throwing the worker onto a dock ramp.
The worker fell approximately six metres, according to the initial account.
He was extricated by emergency crews and airlifted to hospital.

Early Observations
The initial account described the lift as positioned on built-up ground close to an unstable slope. Local fire officials reported that the machine tipped over a hill and that the worker landed on a dock ramp. The exact ground conditions and the machine’s position at the time of the overturn have not been established as causes.
The initial account also speculated that the worker may not have been wearing a harness connected to the platform. This has not been confirmed, and the available information does not establish whether fall-protection equipment contributed to the outcome.
Why This Incident Was Possible
Boom lift stability can be affected by ground strength, slope, surface preparation, machine position and operating configuration. Built-up ground near an edge may require careful assessment to determine whether it can support the machine safely.
The cause of this overturn has not been determined. Investigators would need to establish the ground conditions, the lift’s setup and operating position, and whether the site was assessed before work began.
Industry Reminder
Boom lifts should be positioned only on ground that has been assessed as suitable for the machine and its operating configuration. Slopes, fills, edges and concealed voids can affect stability, even when the surface appears firm.
Workers should follow the manufacturer’s operating instructions and use the fall-protection equipment required for the machine and task. Work planning should also include safe access for emergency crews and a response plan for fuel or hydraulic leaks.

How Boom Lift Overturns Can Be Prevented
Assess ground before positioning the lift
Check ground strength, slope, fill, edges and possible voids. Do not rely on appearance alone when deciding whether a surface can support the machine.
Follow manufacturer operating instructions
Use the lift within its specified limits and confirm the machine is set up for the ground and work conditions.
Keep clear of slopes and edges
Position the machine at a safe distance from embankments, retaining edges and other areas where ground could fail.
Use required fall protection
Follow the manufacturer’s instructions and the work plan for harnesses, lanyards and approved platform anchor points.
Plan emergency access and spill response
Consider how responders will reach an injured worker and have suitable materials available to contain fuel or hydraulic-fluid leaks.
