SUB-RAIL & rail

Corrosion-Resistant Aluminum Sub-Rail:

	Acts as barrier between the concrete and the hardened steel rail;
	Prevents rust in a corrosive concrete environment.

Built-in Anti-Tip into Aluminum Sub-Rail:

	Provides stability;
	Provides safety for systems with a high height-to-width ratio;
	Built-in anti-tip meeting the most severe seismic regulations;
	Meets UBC requirements.

	Note:

	Anti-Tip Sub-Rail Dimensions: Width: 5.47 inches (139 mm) Height: 1 inch (25.4 mm)

Two Anti-Slip Grooves:

	Prevents sub-rail to slip when pouring concrete topping;
	Grout infiltrates under the sub-rail and inside the grooves thus preventing lateral movement.

Two-Piece Spliceless Track:

	Sub-rail continuously supports the top hardened steel rail at the junction point;
	Restricts both vertical and horizontal movement;
	Ensures a smooth weight transfer from one track section to the other;
	Provides greater structural rigidity;
	Ensures that all rail connection joints provide horizontal and vertical continuity between rail sections;
	Prevents any vertical difference between two adjoining rails compared to one-piece rail with a tongue-and-groove joint;
	Eliminates track deflection;
	Provides a quiet operating system;
	Permits easy and instant removal/replacement of the top hardened steel rail compared to a one-piece rail construction.

	Notes:

1	Sub-Rail Dimensions: Width: 3.25 inches (82.55 mm) Height: 1 inch (25.4 mm)
2	Rail Dimensions : Width: 1 inch (25.4 mm) Height: 0.75 inch (19.05 mm)

Rail joints staggered with sub-rail joints, and parallel rails staggered with sub-rail joints:

	Prevent the adjoining rail splice to be at the same location;
	Prevent the wheels of a same carriage to cross a rail splice joint at the same time;
	Ensure a better weight load distribution from one parallel rail to the other;
	Eliminate any rail deflection.

	Note:

	Sub-Rails are supplied in sections of 144 inches (365.76 cm) and rails are supplied in sections of 121.42 inches (308.4 cm).

Interlock Steel Rail Connector:

	Eliminates rail separation;
	Ensures a gradual transfer of the concentrated wheel point load to and from adjoining rail sections;
	Provides horizontal and vertical continuity between rail sections.

Narrow 3/8-inch (9.5 mm) Wheel Guidance Channels between Sub-Rail/Rail Sections:

	Reduce tripping hazards;
	Prevent dust or paper clip accumulation;
	Reduce debris accumulation and makes cleaning easier;
	Carts easily roll over floor and aluminum sub-rail/rail sections.

Fully-Grouted Aluminum Sub-Rail:

	Fully supported to evenly distribute the weight on the existing slab;
	No shims needed.

	Optional Temporary Cover for Concrete Recessed Rails:

	Prevents concrete infiltration into the rail channel openings when pouring cement;
	Protects rails until carriage installation.
