Uneven Ground Changes How a Scissor Lift Is Selected

A rough terrain scissor lift should not be selected by working height alone.

On an outdoor construction site, the machine must first travel from the unloading point to the actual work zone.

That route may include compacted ground, ramps, uneven surfaces and unfinished access areas.

Only after the machine reaches an appropriate working position should the elevated operating conditions be evaluated.

The Mantall XD140RT is designed around this complete jobsite process.

Travel Capability and Working Level Are Different

Two specifications are especially important when evaluating a rough terrain scissor lift:

Travel gradeability

Allowable operating tilt

They describe different conditions.

XD140RT has a specified gradeability of approximately 30%.

Its current allowable working tilt is approximately:

Front / rear: 3°

Side / side: 1.5°

The 30% gradeability specification describes travel capability.

It should not be interpreted as permission to elevate the platform while the machine remains on the same slope.

4WD×2WS for Jobsite Access

XD140RT uses a 4WD×2WS drive and steering configuration.

Four-wheel drive helps the machine travel across suitable outdoor jobsite routes where a conventional indoor electric scissor lift may not provide sufficient traction.

Typical access conditions may include:

• Compacted construction surfaces
• Prepared outdoor work areas
• Industrial yards
• Infrastructure sites
• Suitable gravel or unfinished access routes
• Ramps within the machine's travel capability

Actual ground suitability should always be evaluated before operation.

Solid Rough Terrain Tires

The current XD Series uses 675 × 280 mm rough terrain tires.

The tire configuration supports outdoor travel where the surface is less uniform than a finished warehouse floor.

This does not mean the machine is suitable for every type of soft or unstable ground.

Before travel, the operator should still consider:

• Ground firmness
• Surface deformation
• Loose material
• Potholes
• Excavations
• Drainage conditions
• Underground structures

A rough terrain tire improves mobility but does not replace ground assessment.

0.17m Ground Clearance

XD140RT has approximately 0.17 m center ground clearance.

Ground clearance helps the chassis negotiate suitable irregularities along the travel route.

However, route planning should still avoid obstacles that could contact the chassis or reduce machine stability.

The objective is to select a practical route rather than test the maximum physical capability of the machine.

30% Gradeability Is for Travel

The current headquarters specification lists XD140RT gradeability at:

30%

This figure should be used when assessing ramps and access routes.

It is not an elevated working-angle specification.

When the machine arrives at the work point, the operator must evaluate the actual working setup separately.

Optional Leveling Outriggers

Automatic leveling hydraulic outriggers are listed as an available XD Series option.

For projects where additional chassis adjustment is required before elevation, the outrigger configuration can provide another setup tool.

Current XD140RT specifications list maximum outrigger leveling capability of approximately:

Front to rear: 6.6°

Left to right: 10.6°

These figures describe the leveling capability of the outrigger system.

They should not be confused with travel gradeability or the machine's normal allowable operating tilt.

Three Different Angle Specifications

For XD140RT, customers should understand three different specifications.

Travel Gradeability

30%

This describes the machine's ability to travel on a suitable slope.

Allowable Working Tilt

Front / rear: 3°

Side / side: 1.5°

These values relate to machine position during elevated operation.

Outrigger Leveling Capability

Front / rear: up to 6.6°

Left / right: up to 10.6°

These values relate to the available leveling range when the applicable outrigger configuration is installed.

Keeping these three specifications separate prevents incorrect equipment selection.

14m Maximum Working Height

XD140RT provides:

Maximum working height: 14 m

Maximum platform height: 12 m

The model is suitable for outdoor tasks where both elevated access and rough terrain mobility are required.

Typical work may include:

Steel structure installation

Industrial construction

Building exterior work

Mechanical installation

Outdoor facility maintenance

Infrastructure projects

Large equipment installation

Construction inspection

345kg Main Platform Capacity

The current platform capacity is:

345 kg

The extended platform is rated at:

136 kg

The platform load must include personnel, tools and other items carried on the applicable platform section.

Load planning is particularly important when workers use the platform extension to approach the work point.

4m Platform after Extension

The main platform measures approximately:

2.5 × 1.6 × 1.15 m

With the extension deployed, the current total platform length is approximately:

4 m

The extension provides approximately 1.5 m of additional horizontal access.

This is useful when the chassis cannot be positioned directly beneath the complete elevated work area.

Use the Extension to Reduce Chassis Repositioning

On outdoor construction projects, the best ground position and the best aerial work point do not always align perfectly.

The 1.5 m platform extension can help operators approach an adjacent work point without moving the entire machine every time.

This can be useful around:

Structural columns

Building edges

Mechanical equipment

Temporary barriers

Construction materials

The extended section remains subject to its applicable 136 kg load rating.

Four-Person Platform Rating

The current headquarters specification lists a maximum of four persons for the XD140RT platform under the stated standard.

The total number of personnel, tools and equipment must remain within the applicable platform capacity and local certification requirements.

For export projects, personnel ratings should always be confirmed against the machine's destination-market certification.

Plan the Route before Unloading

For rough terrain machines, equipment planning should begin before the machine is unloaded.

Check the route from the delivery vehicle to the final work location.

Important information includes:

Route width

Ground condition

Ramp gradient

Turning space

Overhead clearance

Excavations

Temporary roads

Final working surface

A machine may have sufficient traction but still be unsuitable if the route cannot safely support its size and weight.

1.76m Machine Width

XD140RT has a current stowed width of approximately:

1.76 m

This width should be checked against:

Temporary site entrances

Building openings

Access between structures

Stored materials

Traffic barriers

Equipment parking zones

Outdoor sites can still contain narrow access points even when the final work area is open.

Foldable Guardrails for Transport

The current XD140RT height is approximately:

2.65 m with the guardrails raised

1.95 m with the guardrails folded

This difference is useful when evaluating transport, storage or restricted overhead clearance.

Guardrail folding should be treated as a transport configuration and the platform must be correctly prepared before elevated operation.

Turning Space on Construction Sites

The current inside / outside turning radius is approximately:

1.58 m / 3.89 m

This information is useful where the machine must negotiate temporary construction roads or move between structural elements.

Route width should therefore be evaluated together with turning space rather than as a single straight-line dimension.

4220kg or 4680kg Configuration

Current specifications list approximate machine weight as:

Without outriggers: 4220 kg

With outriggers: 4680 kg

The additional configuration weight should be considered during:

Transport planning

Ground assessment

Trailer selection

Loading and unloading

Temporary road evaluation

A route that physically fits the machine must also be capable of supporting its operating weight.

Yanmar Diesel Power

The current headquarters specification lists:

Yanmar 3TNV80F

Rated power: 17.8 kW

Diesel power makes XD140RT suitable for outdoor projects where long operating periods and independent jobsite mobility are required.

The current fuel tank capacity is approximately 57 L.

Maintenance Access Matters on Outdoor Equipment

XD Series product features include dual-side access doors and a swing-out engine compartment designed to improve service access.

This can be useful on rental and construction equipment where routine inspection and maintenance must be completed without excessive machine disassembly.

Service requirements should follow the applicable Mantall maintenance documentation.

A Typical XD140RT Work Sequence

A practical outdoor workflow can be summarized as:

Unload

Confirm the machine can be safely removed from the transport vehicle.

Travel

Use the selected jobsite route to reach the work zone.

Position

Select a suitable location beneath or near the elevated work point.

Assess

Confirm surface condition, slope, load and surrounding hazards.

Level

Where the applicable outrigger configuration is fitted, prepare and level the machine according to operating requirements.

Elevate

Raise the platform only after the machine is correctly positioned for work.

Relocate

Lower the platform and reassess the ground condition before moving to the next work zone.

When XD140RT Is the Right Choice

XD140RT is particularly relevant when:

• Up to 14 m working height is required
• Outdoor jobsite travel is necessary
• Four-wheel drive is beneficial
• A 345 kg main platform capacity is sufficient
• A 4 m extended platform can improve work coverage
• The route includes suitable rough or unfinished surfaces
• Optional automatic leveling outriggers are useful for the project

When Another Machine May Be Better

XD140RT may not be the best choice when:

The site requires significantly more than 14 m working height

The required platform load exceeds 345 kg

The surface has insufficient bearing capacity

The machine must cross severe terrain beyond its rated capability

Long horizontal outreach is required

In these cases, another rough terrain scissor lift or boom lift configuration should be evaluated.
