High additional loads and the consequence of long down times are a challenging combination for the design of cable carriers. KABELSCHLEPP Metool offer the solution with products in multiple chain band design, for steel as well as synthetic material products.
Fundamentally, stability and durability are the key features of all cable conveyors in the KABELSCHLEPP range. This principle of construction is designed per se into all types. However, in many areas of application, extreme operating and environmental conditions are found, requiring special solutions.
The comprehensive portfolio, in combination with many years of engineering know-how, makes KABELSCHLEPP Metool optimally equipped for "tough" applications. In this context, cable conveyors in the multiple band design have proven themselves: by using an additional chain band, the additional load can be increased by approximately 50 percent in comparison to a conventional design.
Reinfroced for challenges
A multiple band design recommends itself if there are space constraints albeit l large number supply lines must be carried, with a higher weight and larger diameters. Here, conventional double-side band carriers could attain their load limit.
If alternative installation options are excluded, such as opposing or nested chains, products with multiple belt design provide an alternative application to fit given envelope space.
Aluminium cross stays allow precise chain widths and high torosional stability. Whilst three or four band chains the most common versions, KABELSCHLEPP Metool have even already designed chains with seven side bands.
These designs have proven themselves in heavy manufacturing machinery, in steelworks, on paper machines as well as on the gantry of an MRT system.
If the reason is the complexity of a system with multiple supply lines, the required performance with specific properties and diameters of cable, or the distance to travel – the additional load exceed the parameters of a conventional design and subsequently, their continuous functionality is not ensured.
"For example, large power lines are more or less copper strands with a high weight metre", says Thomas Ameis, design manager for power chain systems at TSUBAKI KABELSCHLEPP. "In addition, there are other cable and large OD, heavy hydraulic hoses, wich can even bring steel chains to their limits." Failure of the drag chain system usually means machine shutdown, likely in the production: to be prevented at all cost.
Because of the rigid design of a multiple band chain, all "media" to be carried can be managed reliably.
Double for high performance
Double-side band carriers are specifically designed for durability. Initially presented last year for STEEL LINE LS 1050, and the MC 1300 hybrid power chain, the double-side band found appreciation in practice. Essentially, each of the normal chain bands was reinforced with a second one. The result was superior stability so that in direct comparison to the standard versions. The steel chain in double-side band design gained up to 40 percent more self-supporting length. The hybrid chain with four synthetic material side belts gined up to 30 percent travel. In addition, the LS 1050 convinced with longer service life, even at greater dynamic loading and high travel speeds. The MC 1300 shows high tensile rigidity and lateral stability.
