Travel access
Spider lifts can have compact travel dimensions, but the complete route must be checked for width, height, turning, gradients and floor conditions.
Set-up space
Many spider lifts deploy outriggers. The final operating footprint can therefore be considerably more important than the travel footprint.
Surface and ground
Tracked travel can help in some conditions, but bearing capacity, surface protection and manufacturer limits still apply.
When conventional boom access may suit
Where there is adequate ground space, suitable access and a straightforward operating area, a self-propelled or other boom-type option may be more efficient.
Compare the complete operating footprint
Spider lifts can travel through restricted routes in a compact configuration, but their final set-up may require outriggers and a suitable support area. Conventional boom equipment may need more travel width yet use a different operating footprint. Measure the route and the work zone separately rather than comparing only one published width.
Include the delivery and recovery route
Restricted sites can become difficult before the machine reaches the work area. Gates, kerbs, ramps, soft landscaping, internal thresholds and tight turns can all affect delivery and recovery. Provide a route description and photographs where useful so the supplier can consider how the proposed equipment will reach and leave the operating position as well as perform the task.
