High additional loads and the consequence of long down times are a challenging combination for the design of cable carriers. TSUBAKI KABELSCHLEPP offers a solution with products with a 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. All models are designed with this principle of construction in mind. 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 TSUBAKI KABELSCHLEPP optimally equipped for tough applications. By using an additional chain band, the additional load can be increased by approximately 50% in comparison to a conventional design.
Reinforced for challenges
A multiple band design is ideal if there are space constraints, where a large number supply lines must be carried, with a higher weight and larger diameters. Here, conventional double-side band carriers could reach 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 space.
Aluminium cross stays allow precise chain widths and high torsional stability. Whilst three or four-band chains are the most common versions, TSUBAKI KABELSCHLEPP has 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 application requires a complex system with multiple supply lines, the required performance includes specific properties and cable diameters or there is a large distance to travel, the additional load may exceed the parameters of conventional designs and subsequently their 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, and needs to be prevented at all costs. Because of the rigid design of a multiple-band chain, all objects 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 is reinforced with a second one. The result is superior stability in direct comparison to standard versions. The double-side band design steel chain gains up to 40% more self-supporting length. The hybrid chain with four synthetic material side belts gains up to 30% 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.
