Trailer-Mounted EWPs
A trailer-mounted EWP — also called a towable boom lift, towable EWP, tow-behind cherry picker, towable cherry picker or trailer lift — is a self-contained elevated work platform mounted on a road-registered trailer. It is towed to site by a ute or light truck, then self-levels and deploys the boom independently. The trailer format gives contractors, councils and arborists access to EWP capability without a purpose-built truck chassis.
EWP Australia inspects, certifies and carries out major inspections on all trailer-mounted EWP models operating in Australia. We service Nifty Lift trailer models, Hinowa spider trailer lifts and a wide range of imported and Australian-market towable boom lifts.
Other Names for This Equipment
All of the above terms refer to equipment within this category. Different industries, regions and manufacturers may use different names — EWP Australia services all of them.
Equipment Variants
Towable Boom Lift
A towable boom lift uses a standard ball or pin coupling to attach to a tow vehicle. On site, outriggers are deployed and the diesel or electric boom is driven from the platform controls. Working heights typically range from 12 m to 22 m.
Spider Trailer Lift
A spider trailer lift combines spider lift outrigger geometry with a trailer-mounted format — delivering low ground bearing pressure, slope tolerance and compact transport width without a truck. Popular for arborists and councils managing turf and landscaped areas.
Insulated Trailer EWP
Some trailer-mounted EWPs carry insulated boom sections for live-line LV or HV work. These units serve electrical contractors who need insulated access without a dedicated bucket truck.
How to Choose
Towing Capacity
Confirm your tow vehicle's rated towing capacity against the trailer GVM. Most towable boom lifts are 1,500 kg to 4,500 kg — check your ute or van's towing limit.
Working Height
Trailer EWPs typically reach 12 m to 22 m. Select on working height required at the work point, not boom length.
Outrigger Footprint
Check the deployed outrigger footprint against the site's available space. Urban sites may have kerbs, fences and street furniture limiting outrigger extension.
Power Source
Diesel models are self-sufficient on site. Electric trailer EWPs need a power outlet or generator — suitable for parks and campuses with power access.

Australian Standards & Inspection
Trailer-mounted EWPs are subject to the same AS/NZS 2550.10 inspection requirements as any MEWP — annual inspections and 10-year major inspections. Additionally, the trailer itself (chassis, couplings, lights, brakes) must comply with the relevant state heavy vehicle or trailer registration standards. EWP Australia performs compliant structural inspections on all trailer-mounted EWP models.
Common Questions
What licence do I need to tow a trailer-mounted boom lift?
The licence and towing regulations depend on the trailer's GVM and your state. In most states, a standard car licence covers trailers up to 750 kg GCM; above that, additional endorsements or a light rigid licence may apply. Always check with your state's road transport authority.
Can a towable boom lift be used on slopes?
Towable boom lifts must be on level ground (within the manufacturer's rated slope tolerance, typically 3–5°) before deployment. Spider trailer lifts have greater slope capability due to independently adjustable outriggers. Never operate a trailer EWP on a gradient beyond its rated limit.
Does a trailer-mounted EWP need registration?
Yes. The trailer component must be registered as a road trailer in the relevant state. The EWP structure itself is inspected and certified separately under AS/NZS 2550.10.
