Wire guidance involves cutting a 10-12mm deep x 3mm wide path in the concrete slab, inserting an electrical wire to form a loop/circuit, sealing over the laid wire & then connecting the wire ends to a line driver which is generally supplied with the VNA equipment.
Why Choose Wire Guidance
Both guidance options will create the following:
There are however, some differences that need to be factored into your decision making process:
Obviously if you have a 100mm(h) rail running down each side of the aisle, you can’t put a pallet on the ground, so you will need to factor in the cost of another set of beams in every bay, which usually have a lowest level of approximately 250mm. Apart from the cost of another set of beams per bay, you then have the issue of housekeeping behind the rail & under the bottom beams. Guide wheels are a moving part & as such are a wear & tear item, they also make the unit wider.
The mild pinball action causes the rails to come apart or bend usually in the sections where the 6 meter rail lengths are welded together over a period of time. This action also loosens the chemical anchors over time which will need to be drilled out & replaced with new ones. Finally when you decide to move premises, you will have to make good the floor, that’s a lot of chemical anchors that will need to be drilled out & the holes back-filled.
Not only is wire guidance a far cheaper option than rail guidance (see cost benefits), it is quicker to install (up to 800 meters per day), requires no ongoing maintenance & does not affect making good slabs upon relocation.
