Rent diesel articulating boom lifts - maximum reach for rough terrain

Anyone who has to reach over a pipe bridge on site, get to a facade behind trees or assemble a steel structure at a height of 40 m will not get far with a straight telescopic boom lift. This is where diesel articulating boom lifts come in: four-wheel drive, articulated boom, oscillating axle and working heights up to 49 m - as a rental machine from the Luibl rental fleet, delivered from Passau throughout the Czech Republic.

On paved hall floors, electric platforms are sufficient. As soon as gravel, clay, snow or gradients come into play, the situation changes. Diesel articulating boom lifts are designed precisely for this field of use - for three reasons:

• Independence from the power grid: On shell construction sites, in steel halls without a connection or during tunnel and track work, an external power supply is rarely available. The diesel engine runs independently; one tank lasts for several shifts.

• Torque for gradients and ground conditions: Models such as the Genie Z45/25 XC or the Z51/30J RT handle gradients of up to 45 %. On gravel or soft ground, the advantage of a combustion engine over battery solutions becomes clearly apparent.

• Load capacity and reach in one machine: Heavy-duty versions such as the Manitou 160 ATJ Plus lift 408 kg into the basket - enough for two fitters plus tools and material. The outreach of this model is 8.52 m.

Compared with a straight telescopic boom lift, the decisive advantage comes into play when there is an obstacle between the machine and the work point - a roof overhang, a utility line, an annex. This is exactly where the articulated boom becomes the tool of choice.

The terms working height and up-and-over height are often confused in rental offers. For selection, however, the distinction is worth real money.

Working height is the theoretical reach height of a person standing in the basket - i.e. platform height plus 2 m. For the Genie ZX-135/70 this is 43 m with a platform height of around 41 m. This figure appears in the data sheet and in the rental offer.

Up-and-over height describes something else: how high can the basket be raised while simultaneously reaching sideways over an obstacle? This is where the articulation point (riser) comes into play. Unlike a straight telescopic boom lift, an articulating boom lift has one or more additional pivot points on the boom. This allows the basket to be guided over edges, railings or roof projections without having to reposition the machine.

The outreach depends directly on the model. Examples from the Luibl rental fleet:

• Genie Z45/25J RT (16 m working height): bridges a lateral distance of around 8 m

• Manitou 160 ATJ Plus (16.21 m): outreach 8.52 m with 408 kg basket load

• Magni DAB28RT (28 m): basket rotation up to 180 degrees, continuous 360-degree superstructure rotation

• Genie ZX-135/70 (43 m): four steering modes including crab steering and coordinated all-wheel steering

On models with a large working height, negative reach is also relevant - i.e. working below the level of the machine, for example when inspecting the underside of a bridge or working on slopes. Negative working heights down to -6 m are available in the Luibl diesel range.

Diesel articulating boom lifts are not all-purpose machines. They play to their strengths in clearly defined scenarios:

• Steel construction and hall assembly: setting beams, tightening connectors, checking welds - the basket load of 230 to 450 kg allows tools and material directly on hand.

• Facade work on complex geometries: projections, balconies and roof overhangs are reached under or around with the articulated geometry without repositioning the machine.

• Maintenance of utility lines and power poles: this is where negative reach is used when working from an earth embankment or dam crest.

• Bridge inspection and tunnel construction: long reaches up to 49 m and continuous superstructure rotation allow precise positioning even in confined conditions.

• Industrial assembly in factory halls without a power supply: during the construction phase, before the hall infrastructure is commissioned, diesel is often the only option.

Off-road capability thanks to four-wheel drive and oscillating axle

What really sets a diesel articulating boom lift apart from an indoor machine is the chassis. Three components are decisive here:

• Permanent four-wheel drive: The engine power is distributed to all four wheels. This significantly improves traction on gravel, clay, wet ground or snow compared with rear-wheel drive.

• Active oscillating axle system: On uneven terrain, the oscillating axle compensates for ground irregularities so that all four wheels keep contact with the ground. Without this system, the machine rocks on bumps and stability decreases.

• Rough-terrain tyres: Coarse-lugged tyres with an off-road tread are standard. Some models (such as the Magni DAB28RT) are fitted with non-marking tyres that leave no tracks even on sensitive surfaces - useful for mixed indoor/outdoor use.

Gradeability ranges between 30 % and 45 % depending on the model. Important: these values apply to travel with the boom retracted. Anyone working on a slope must level the machine first - stability is checked via the load chart and tilt sensor.

The right machine follows from four parameters that should be clarified before every enquiry:

• Required working height including a safety margin: Better 2 m of reserve than working at the limit. A 16 m platform for a 14 m task is a better choice than a 43 m machine, which is considerably more restricted in manoeuvrability.

• Basket load according to number of persons plus material: Two fitters, cordless screwdriver, fixing material, fall protection equipment - realistically that quickly adds up to 250 to 350 kg. Models with a 230 kg basket load (Manitou 200 ATJ) are then no longer sufficient.

• Outreach with the obstacles actually present: The data sheet or advice based on the site geometry is indispensable here. Load charts show which basket load is permitted at which boom position.

• Transport dimensions and access: A ZX-135/70 with a total weight of over 20 t needs different low-loaders and access routes than a 16 m Genie. The delivery dimensions must suit the site access.

On sensitive ground, it is worth looking at the ground pressure per wheel. Where the ground is critical, spider lifts are a sensible alternative - these are also available in the Luibl range.

Anyone operating an aerial work platform needs the required operator qualification in line with applicable Czech safety rules and CSN EN standards. It usually comprises theoretical instruction, practical exercises and a final proof of competence. Written authorisation by the employer is recommended.

The international operator certificate is the PAL Card from IPAF (International Powered Access Federation), which many general contractors require in practice - in addition to the qualification required by the applicable rules.

Other relevant regulations:

• Occupational safety rules (Act No. 309/2006 Coll.): operation of aerial work platforms

• CSN EN 280: safety requirements, design calculations and tests for mobile elevating work platforms

• Government Regulation No. 378/2001 Coll.: legal framework for the provision and use of work equipment

• Austria (AUVA / AM-VO): comparable requirements, governed by the Austrian Work Equipment Ordinance

Before use, we recommend a daily visual and function check. The periodic inspection under Government Regulation No. 378/2001 Coll. by a competent person is documented on delivery for Luibl rental machines.

Luibl operates its own low-loader fleet. With diesel articulating boom lifts this is not trivial: machines from 16 m working height typically weigh 7.5 t and more, the ZX-135/70 weighs over 20 t. External hauliers often deliver with unclear time windows - our own fleet allows predictable delivery dates, including across borders.

Delivery areas: Czech Republic, Germany, Austria, Switzerland, Poland, Italy, Hungary, Luxembourg and other European countries - delivered by low-loader from Passau throughout the Czech Republic.

Service during the rental period: For technical faults or operator briefing on handover, fitters can be sent to the site on request. This is particularly relevant for large machines, where downtime jeopardises the daily planning of the entire site.

Long-term rental: For projects lasting several months, long-term terms are available including periodic inspection under Government Regulation No. 378/2001 Coll. and annual maintenance. Useful on large construction sites where the same machine is tied up for the entire construction phase.

Which machine suits which task can in most cases be clarified in 5 minutes based on the site geometry and the required basket load. For a technical assessment of reach, lateral outreach and delivery date, direct contact with the rental team is the fastest route: https://www.luibl.eu/kontakt/
