14m Working Height Creates a Different Transport Challenge
AMP40 is the highest-working-height model in the current Mantall AMP Series.
It provides:
Maximum working height: 14 m
Maximum platform height: 12 m
At this height class, the challenge is no longer only reaching the elevated work point.
The customer must also consider how a relatively tall single-mast machine will pass through the building and reach the actual work area.
AMP40 addresses this problem with a dedicated tilt-back transport configuration.
Why AMP40 Has a Tilt-Back Device
AMP20, AMP26 and AMP32 are designed to pass through suitable standard access routes without tilting the mast.
AMP40 is different.
Its normal stowed height is approximately:
2.76 m
For this reason, AMP40 is equipped with a tilt-back device as part of its standard configuration.
The tilt-back system allows the machine to be placed in a lower transport position when additional overhead clearance is required.
1.98m Height in the Tilted Position
When tilted back, AMP40 has an approximate height of:
1.98 m
This is one of the most important dimensions for customers considering a 14 m portable mast platform.
The machine can therefore be evaluated in two configurations.
Normal stowed configuration:
1.46 × 0.78 × 2.76 m
Tilted transport configuration:
Approximately 1.98 m high
This allows project planners to consider routes that would not accommodate the machine in its normal upright stowed condition.
Tilted Length Becomes 2.87m
Reducing transport height changes another dimension.
When AMP40 is tilted back, the machine length increases to approximately:
2.87 m
This means the transport route must be evaluated for both:
Vertical clearance
Horizontal maneuvering space
A doorway may provide sufficient height after the machine is tilted, but the corridor or turning area must also accommodate the longer tilted configuration.
Check the Entire Access Route
For AMP40, do not check only the doorway immediately next to the work area.
The complete movement route should be reviewed.
This may include:
• Building entrance
• Interior doors
• Corridors
• Elevators
• Turning corners
• Ramps
• Storage areas
• Final working room
The most restrictive point anywhere on the route can determine whether AMP40 can reach the intended work location.
14m Reach for High-Ceiling Facilities
AMP40 is particularly relevant when indoor service points extend beyond the range of lower AMP models.
Typical high-level work points may include:
• High-bay lighting
• Roof-level electrical equipment
• Suspended mechanical systems
• Exhibition hall structures
• Sports hall ceiling equipment
• Atrium fixtures
• High-level signage
• Industrial building services
For these projects, 14 m working height may be necessary even when the machine must still travel through conventional building access routes.
120kg Rated Platform Capacity
AMP40 has a rated platform capacity of 120 kg.
This is lower than the 159 kg capacity used by the lower-height AMP models.
For this reason, AMP40 should be selected primarily when additional vertical reach is required rather than simply choosing the tallest model by default.
The platform load must include the operator and all tools or equipment carried at height.
A High-Reach One-Person Work Platform
AMP40 uses the same compact platform basket concept as the AMP Series.
Basket size is approximately:
0.69 × 0.68 m
This configuration is suitable for focused one-person work rather than multi-person installation tasks.
Typical activities include:
Inspection
Electrical servicing
Lighting maintenance
Small component replacement
Adjustment work
Facility maintenance
0.78m Machine Width
Despite its 14 m maximum working height, AMP40 maintains an overall width of approximately:
0.78 m
This relatively narrow chassis helps with movement through suitable indoor routes.
However, machine width alone should never be used to determine access suitability.
For AMP40, transport height and tilted length are equally important.
Working Close to the Structure
The current AMP40 specification lists approximate wall-access distances of:
Front: 0.42 m
Side: 0.65 m
These values should be considered when determining how close the platform can be positioned to a suitable elevated work point after the machine has been correctly set up.
Stabilizer Setup before Elevation
AMP40 uses stabilizers for elevated operation.
The machine should be positioned on a firm and suitable supporting surface before the stabilizers are deployed.
The operating area must provide enough space for:
Machine positioning
Stabilizer deployment
Operator access
Surrounding clearance
The transport configuration and the operating configuration should always be evaluated separately.
Transport Configuration Is Not the Working Configuration
The tilt-back device is intended to help move the machine through suitable access routes.
It is not the elevated working configuration.
A typical process is:
Move the machine toward the restricted access area
Place AMP40 in the tilt-back position when required
Move through the suitable route
Return the machine to its normal configuration
Position it at the work location
Deploy the stabilizers correctly
Confirm machine level
Begin elevated operation
This distinction is important when planning indoor use.
548 / 595kg Machine Weight
Current headquarters specifications list approximate AMP40 machine weights of:
AC version: 548 kg
DC version: 595 kg
At this weight, customers should check:
• Elevator capacity
• Floor loading requirements
• Loading equipment
• Vehicle capacity
• Ramps
• Transport handling method
The lighter appearance of an aluminum mast should not replace an actual weight check when planning movement through a building.
AC and DC Power Options
AMP40 is available with AC and DC configurations.
Current specifications list:
AC: 220V / 110V
DC: 12V
The appropriate configuration depends on the intended operating environment and available power supply.
Why Not Simply Choose AMP40 for Every AMP Job?
The tallest model is not automatically the best model.
AMP40 provides the greatest vertical reach in the AMP Series, but it also has:
Higher machine weight
Higher normal stowed height
A 120 kg platform capacity
A tilt-back transport procedure
Longer dimensions when tilted
Customers who only require 8 m, 10 m or 12 m working height may find another AMP model more practical.
AMP40 is most appropriate when the project genuinely requires the 14 m working envelope.
Typical Scenario: Exhibition Hall Maintenance
Large exhibition halls often have lighting, signs and suspended equipment at significant heights.
AMP40 can provide the required 14 m working range while the tilt-back configuration helps address access routes with limited overhead clearance.
Typical Scenario: Sports Venue Servicing
Sports halls and indoor venues can contain lighting and ceiling equipment well above conventional maintenance height.
Before AMP40 is selected, the contractor can check both the high working point and the lower transport clearances between the entrance and the work area.
Typical Scenario: Industrial High-Bay Building
Factories and high-bay industrial buildings may require maintenance around roof-level electrical or mechanical systems.
AMP40 can be considered when the work point requires up to 14 m working height but a large self-propelled machine would be impractical inside the building.

FAQ
Q: Why does AMP40 have a tilt-back device?
A: AMP40 has a normal stowed height of approximately 2.76 m. The tilt-back device reduces its transport height to approximately 1.98 m for suitable access routes with lower overhead clearance.
Q: How long is AMP40 when tilted back?
A: The current specification lists an approximate tilted-back length of 2.87 m, so turning and corridor space should be checked in addition to doorway height.
Q: What is the maximum working height?
A: AMP40 provides a maximum working height of 14 m and a maximum platform height of 12 m.
Q: What is the rated platform capacity?
A: The current AMP40 specification lists a rated capacity of 120 kg.
Q: Do all AMP models require a tilt-back device?
A: No. Current Mantall documentation identifies the tilt-back device specifically for AMP40. The lower AMP20, AMP26 and AMP32 models do not require this configuration for normal standard-doorway access.
