• Can the system be used indoors and outdoors?

    Bomac can provide the Altrac system to suit a wide variety of different environments which can be quite aggressive in nature. With the use of various coatings and stainless steel components Bomac can design a system best suited to your environment.

  • What is e-coating?

    Commonly known as E-COAT, or ELECTRIC-PAINT, EDP is more technically termed–CATHODIC ELECTROPHORETICALL DEPOSITED PAINT. 

    The paint formulation applied is the latest Lead free type “Medium Build” Epoxy. The process utilizes preparatory immersion steps including cleaning, and fine grain Zinc Phosphating before the painting stage.

    Post painting, the coating is oven cured at 175 C. E-coat offers increased corrosion resistance and in a 5% neutral salt spray test to AS2331.3.1 only showed the onset of red rusting for a 20um coat after 840hrs. Applied over zinc plated steel, the corrosion resistance increases from 840hrs, to up to 2000hrs depending on zinc thickness. 

    The chemical resistance of E-coat is good against mineral and vegetable oils, hydraulic fluids, glycols, gasolines, weak acids, and common organic solvents. However it is not resistant to warm caustic. E-coat will also have colour degradation with prolonged exposure to ultraviolet radiation however this can easily be overcome by the application of a powder topcoat.


  • What alloy is the Altrac material?

    The Altrac rail is made from 6005A-T5 grade alloy

    Altrac is extruded from aluminium extracted and smelted in Australia. Each batch of Altrac is NATA certified having undergone chemical and mechanical analysis to ensure the highest quality.

  • What is the heaviest weight Altrac can lift?

    The limitation of the Altrac system is determined by the Trac trolleys these trolleys can carry up to 500kg each but a 1000kg system can be achieved by linking two trolleys together with a load bar.

  • Whats the smallest radius that Altrac can be rolled to?

    Altrac can be rolled to a radius of 1000mm.

  • Are the trolleys rated for fall arrest?

    The 500kg rated Altrac Trac trolleys are suitable for fall arrest and rope access applications.   This particular range of Bomac Trac trolleys exceeds the stated 15kN ultimate loading required under the code.

  • Can the trac trolleys be used inverted?

    The Trac trolleys may be used in any orientation as long as they are loaded in tension when the load is applied. If you have an application where the trolley needs to be inverted talk to Bomac about your project for additions to our standard trolleys for this purpose.

  • What size bolt fits in the slot?

    It is actually a nut that slides into the T-slots of the Altrac and StrongBac extrusion. Bolts are not used in the T-slots as the head of a bolt does not have the required bearing surface. The nut size suits an M8 bolt.
