A machine can look right on paper and still lose time on site. It may have the required working height, yet be too wide for the gate, too heavy for the trailer, or unable to set up safely where the work actually is. This industrial platform specification guide focuses on the figures that affect productive days, safe operation and the real cost of ownership.
Start with the job, not the machine category
Before comparing spider lifts, towable platforms, scissor lifts or boom lifts, define where the basket needs to be and what sits between the operator and that point. A 17-metre working height is only part of the requirement. You may need side outreach over a roof edge, clearance around racking, a narrow route through a building, or the ability to work on rough ground without repeated repositioning.
Write down the highest point of work, the furthest horizontal reach, the access route width and the ground conditions. Also consider how often the machine will move during a shift. For a maintenance team carrying out several jobs around a large site, a self-propelled boom can save significant time. For occasional work at changing locations, a road-towable platform may make more commercial sense.
The right category follows the application. A compact tracked spider lift is often the answer for restricted access, sensitive ground or uneven terrain. A stabilised rough-terrain boom is built for outdoor productivity where ground conditions are less forgiving. Scissor lifts provide efficient vertical access on suitable, level surfaces, while conventional booms can suit sites where travel speed and continuous manoeuvrability matter more than a compact stowed footprint.
Industrial platform specification guide: the core measurements
Working height, platform height and real clearance
Working height is normally calculated by adding an allowance for the operator to the platform floor height. It is useful for initial comparison, but platform height is the figure to check when clearance is tight. If an obstruction sits beneath the work area, basket floor height and the geometry of the boom or jib matter just as much as the headline working height.
Do not specify too closely to the minimum. A machine that just reaches can force awkward positioning and increase the number of moves. Allow sensible margin for gradients, set-up position, building projections and the fact that the work point may not be as accessible as the survey suggested.
Outreach, up-and-over clearance and jib movement
Outreach is the horizontal distance from the machine to the basket. For cladding, roofing, tree work, industrial maintenance and work over obstacles, it can be more valuable than an extra metre of vertical height. Check the outreach chart rather than relying on a single maximum figure. Many booms achieve their furthest reach only at lower basket heights or with reduced platform capacity.
Up-and-over clearance describes the ability to reach beyond an obstruction such as a parapet, machinery, extension roof or hedge line. A fly jib adds useful positioning flexibility, particularly when the operator needs to approach the work from above or around a structure. However, it is not a substitute for enough base outreach. Both figures need to suit the actual job.
Stowed dimensions and turning space
Measure every restriction, not just the narrowest doorway. Width is usually the first filter, but stowed height, overall length and turning radius can be equally limiting. A machine may pass through a 1.1-metre entrance but be unable to negotiate the turn immediately behind it.
For indoor or sensitive sites, consider ground clearance, track or tyre type, machine weight and whether the platform can be driven at full working height. Non-marking tyres may be essential in finished environments. Compact spider lifts often earn their place because they can pass through narrow access routes before deploying stabilisers outside, but their set-up envelope must also be measured.
Platform capacity and what goes in the basket
Basket capacity covers people, tools and materials together. Two-person rating does not automatically mean two operatives can work with all the equipment they need. A typical maintenance task may involve power tools, cable, fixings, test equipment or replacement components. Arborist work may bring saws and rigging equipment. Allow for the whole load, not just personnel.
The capacity also affects working envelope on some machines. Check whether the platform maintains unrestricted outreach at full load, or whether the safe working range changes with weight. Never treat the basket as a materials lift or exceed the rated load to finish a job quickly.
Match the chassis to the ground conditions
Ground conditions are a specification issue, not an afterthought. A platform with excellent reach is of little use if it cannot travel, level or set up safely where required. For firm, prepared ground, conventional wheeled machines may offer fast travel and straightforward operation. On wet, sloping, loose or landscaped areas, tracks, four-wheel drive, oscillating axles and stabilisers can make the difference between productive access and a cancelled shift.
Stabilisers widen the operating footprint and can provide secure levelling on uneven ground, but they require room and suitable bearing capacity. Check the maximum stabiliser spread, individual outrigger loads and any restrictions on operating with stabilisers deployed. Auto-stabilisation can speed up set-up, but the operator still needs competent ground assessment and must follow the manufacturer’s instructions.
Consider ground pressure where access crosses paving, lawns, suspended slabs or service routes. Low ground pressure can protect surfaces, but it does not remove the need to confirm what lies beneath. If the site has questionable ground bearing capacity, arrange assessment before delivery rather than discovering the issue with the machine at the gate.
Choose power around duty cycle and site rules
Electric, diesel, hybrid and battery-diesel power configurations all have a place. Electric operation suits indoor work, low-emission zones and noise-sensitive locations, provided charging arrangements support the planned duty cycle. Diesel remains practical for demanding outdoor work and longer shifts, especially where charging infrastructure is limited.
Hybrid or bi-energy machines can be a sensible compromise for contractors moving between internal and external work. The trade-off is higher purchase complexity and the need to understand how each power mode affects performance. Ask about charging time, battery run time, fuel consumption, cold-weather operation and whether the machine can work while charging where appropriate.
Also check the power source for tools in the basket. A mains socket, generator or air and water lines may reduce the need to run separate leads or equipment at height. These details are often what make a platform genuinely efficient for a particular trade.
Transport weight is a buying decision
Gross vehicle weight, machine weight and trailer capacity should be checked together. A towable platform may simplify transport, but only if the towing vehicle is rated correctly and the driver has the appropriate entitlement. Add fuel, loose accessories and any trailer equipment to your calculations. The legal and practical payload is rarely the same as the figure remembered from a brochure.
For self-propelled access platforms, decide whether you will use your own transport, a plant lorry or delivered transport. Loading angle, tie-down points, overall height and width on the trailer all matter. Frequent third-party haulage can alter the economics of a lower-cost machine, while a road-towable unit can offer real flexibility for an owner-operator with suitable towing capacity.
New versus pre-owned: compare condition, not just price
A pre-owned platform can be a strong commercial purchase when its history, condition and specification match the work. Look beyond hours alone. Ask about service records, inspection status, battery condition, hydraulic leaks, tyre or track wear, structural repairs and the function of controls, emergency lowering and safety systems.
New equipment offers the latest specification, warranty cover and a known starting point for ownership planning. Used equipment can reduce capital outlay and may be available sooner. Which route works best depends on utilisation, finance terms, expected resale value and how critical downtime would be to your operation.
At Pure Platforms, the useful conversation starts with the application, access route and transport plan, then works back to available new or pre-owned machines. That approach also makes part-exchange values, delivery costs and finance quotations easier to compare on a like-for-like basis.
Specify for the next job as well as this one
Avoid buying excessive height or capacity simply because it sounds future-proof. Larger machines bring higher weight, transport demands and purchase cost. Equally, choosing the smallest possible platform can limit the work you can win and create daily compromises for operators.
The best specification is a machine that reaches the required work safely, fits the site without drama and earns its keep across enough of your planned workload. Bring site measurements, photos and the likely transport arrangement into the quotation discussion. A few accurate details before purchase are worth far more than a platform that arrives ready to work everywhere except the job that justified buying it.
