Please firstly consult the data sheet and HGMS movies to understand if HGMS is suitable for your needs.

For further technical details, please contact us.

 

Q. Is it possible to mount HGMS on a 6x6 vehicle, rather than 8x8?

No, HGMS requires an 8x8 vehicle with a 13 ton payload capacity. However MGMS can be mounted onto a 4x4 or 6x6 vehicle with a 4 ton payload capacity.

 

Q. Can the width of the HGMS TRACKWAY be changed?

It is possible to customise any element of HGMS, subject to consultation.

 

Q. What is CBR and how is it relevant to TRACKWAY?

The California bearing ratio (CBR) is a penetration test for evaluation of the mechanical strength of road subgrades and basecourses. It was developed by the California Department of Transportation before World War II.

Ground stability or stiffness is expressed in terms of CBR, this being a commonly used index of the load bearing capacity of substrates encountered in the construction of roads. The CBR defines the local condition as a % of that for a standard material, crushed Californian limestone that has an index of 100.

The CBR rating was developed for measuring the load-bearing capacity of soils used for building roads. The CBR can also be used for measuring the load-bearing capacity of unimproved airstrips or for soils under paved airstrips. The harder the surface, the higher the CBR rating. A CBR of 3 equates to tilled farmland, a CBR of 4.75 equates to turf or moist clay, while moist sand may have a CBR of 10. High quality crushed rock has a CBR over 80. The standard material for this test is crushed California limestone which has a value of 100.

As mud, marshland, peat, sand and snow are all very soft conditions, they have a low CBR. This means vehicles can easily become stuck and cannot gain access in these conditions. Laying TRACKWAY raises the CBR of the ground and therefore permits vehicles traffic in these difficult conditions.

 

Q. Is HGMS effective on all terrain?

FAUN advise that HGMS requires ground conditions to have a minimum California Bearing Ratio (CBR) of 5%. The table below provides a purely theoretical indication of the relationship between ground conditions (CBR), vehicle Military Load Classification (MLC) and the number of continuous passes that can be made along the TRACKWAY before serious damage occurs. The table is based upon ground conditions being perfectly uniform and that no compaction occurs.

 

 

Q. If the CBR along the longitudinal axis of the road varies from left to right, will this lead to slipping or overturning of vehicles driving along the TRACKWAY?

If the ground conditions are not consistent, TRACKWAY will just tilt slightly, but there is no risk of vehicles tipping over.

 

Q. Would TRACKWAY become damaged as a result of unbalanced loads (heavy vehicles using left and right sides of the roadway)?

No, it will not. After a convoy of the trucks has been passed, it may be necessary to re-align the TRACKWAY by adjusting some of the anchorage pickets.

 

Q. What are the technical characteristics of the aluminium?

Tensile strength of 340 MPa

Shear strength of 210 MPa

 

Q. What vehicle should be used to deploy TRACKWAY?

For HGMS to work effectively, a 8x8 flatbed truck with a 16t payload capacity. DROPS/PLS preferred.

 

Q. How are two sections of 50m joined together?

Two half length panels with male/female connectors are slid into position after the second 50m section has commenced the laying process. See image below.

 

 

Q. What certification does FAUN have?

Quality Management

FAUN MV Ltd has been awarded ISO 9001:2000 for its quality management system in relation to the design and manufacture of temporary roadway systems and other similar ancillary military products, including after sales support.

Certificates are available upon request.

 

 

 

Environmental Management

FAUN MV Ltd has been awarded ISO 14001:2004 for its environmental management system in relation to the design and manufacture of temporary roadway systems and other similar ancillary military products, including after sales support.

Certificates are available upon request.

 

 

 

Investors in People

A proven and successful framework for business improvement, the Investors in People award stimulates and challenges organisations to focus on the needs of the people to achieve its objectives. FAUN MV Ltd is a certified Investor in People, and therefore has training, development and innovative people practices at the heart of everything it does.

Certificates are available upon request.

 

 

 

Q. What is the lead time on manufacture of HGMS?

This is largely dependent upon the size of the contract, therefore please contact us to discuss your requirements further. A guideline time would be approximately 18 weeks from receipt of purchase order to completion of manufacture.

 

Q. What are the maximum and minimum temperatures that MLC 70 TRACKWAY can withstand?

Maximum: +40 °C / 104 °F
Minimum: -40 °C / -40 °F

 

Q. Can HGMS roadway be split into smaller pieces?

Yes, there is a split in the TRACKWAY every five meters, so custom lengths can be created by hand.

 

Q. Have HGMS trials been conducted and which whom?

Yes, recent trials include Russia in 2010, Switzerland and Sweden from 2004 to 2008 and Greece in 2001. TRACKWAY has surpassed all competitors in all trials to date.

 

Q. What is the impact of multiple MLC 70 and MLC 80 vehicles passing over MLC 70 TRACKWAY?

The effect between the two weights will be minimal and will be dependent upon the type, makeup and CBR of the substrate and the wheel loading of the vehicle that is making the pass. In actuality there will very little extra degradation of the TRACKWAY between the two vehicle weights, which equates to less than one percent on average.

 

Q. Is it possible to launch TRACKWAY over the front of the vehicle?

This was an old design of deployment system. We no longer recommend nor sell this type of system.

 

Q. When deploying TRACKWAY using HGMS, what can the maximum gradient of the slope be?

The known gradient that HGMS can deploy at is 30% without anchoring. Maximum approach and departure gradient when deploying TRACKWAY is tested at 20%.
