Selecting the right catenary system guarantees that your mobile plant will work
as it was intended. Some businesses have found themselves let down by failing to
use quality components.
VITAL MACHINES use quality manufacturers for proven designs, never 'dabbling' in
low-cost temptations (that will likely fail at the worst possible moment ...)
Our benchmark products from Europe provide tried and proven solutions. Longevity
and consistency of supply are key issues to our customers.
VITAL MACHINES carry 'ready-to-wrap' stocks in our local warehouse. This ensures
that you never need to wait longer than you should! Unique to our industry is a
pre-assembly service. This greatly reduces the commitment to you and demonstrates
our interest in your project and our 'will do' attitude.
Applications
Catenary systems fall under our key category of 'Energy Reticulation'. In addition
to enclosed conductor bar systems, they form the most popular means for providing
continuous energy supply, to plant that travels a predetermined track (like cranes
and bridge scrapers). They require minimal structural support and remain cost effective
- with virtually no maintenance.
Catenary's (particularly 'C' track and 'I-Beam' systems) are an excellent means
for powering electrical and air driven products, like hoists and trolleys on monorails
and jibs. The same product line lends itself to assembly areas - for the support
and distribution of tooling and product, particularly in manufacturing and service
industries.
Our catalogues are well detailed and you can work your way through the selection
of complete systems, or invite us to recommend a system on their behalf.
Technical
VITAL MACHINES provide technical support for three types of energy reticulation
products - catenaries, enclosed conductor bar, and cable reels.
Catenaries are provided in the three most common support mediums: strainer wire,
enclosed profiles ('C' tracks), and 'I' beams. 'C' track catenaries form the most
common marketplace assembly, due to the large number of available minor parts and
their ready substitution.
1. Strainer wire systems provide a simple support 'tight-wire' for open span areas.
They are low cost items, generally suitable for use with low-duty, low-speed machinery.
(We do not recommend the use of strainer wire systems on jib cranes and monorails,
due to the longitudinal bending produced by straining of the wire). They are suited
to outdoor machinery on permanent runways where additional supports are unwelcome
and obtrusive.
2. 'C' track is a specially manufactured profile available in a number of sizes
and carrying capacities. The 'C' section is designed with return stiles that centre
the trolley and eliminate binding and jamming. Trolleys are produced in an array
of carrying capacities and are then matched to differing support saddle types. Support
of hoses, round cables, and flat cables, in nearly any configuration, is therefore
readily achieved. The 'C' track sections normally require regular supports (1.4
to 2m apart). Load charts are available to assist selection.
3. 'I' Beam systems generally operate on the same structural member as the travelling
plant (e.g., a hoist on a monorail). Lightweight trolleys form a compact carrying
mechanism suitable for many applications. Large, high-speed machines (e.g. ship
to shore container cranes) use purpose-built high strength sub-assemblies for long
life and corrosion protection. Anti-strain cords are added for extended cable life.
The advantages of the 'I' Beam system is that no additional structural member is
needed for the energy reticulation. Note that 'I' beam trolleys consume some of
the available travel of the moving plant.
