When installing a crane with a free standing gantry system it is imperative to have the gantry track perfectly level in order for the crane to run true on the rail. In order to make sure the gantry track is installed level our engineers will use packers under the base plate of the crane column as factory floors are never level over a distance.
Level tracks avoid the wheels and gantry's tracks wearing.
If your floor is only a few millimeters out this can be exponential at the top of the crane column where the gantry track sits. To avoid this issue we will always pack the columns whenever possible.
To make the finish look professional and help secure the packed column itself we offer to grout under the bases. This also helps to prevent the floor from cracking. We use non shrink grout, not
cement, as this settles and cracks over time.
Some competitors engineers will just sit the crane columns straight onto your factory floor, in fact most do. This means that tops of the crane columns will sit out of line. To combat this competitors will bend the last few columns into position to accept the bolts from the rail.
This can be dangerous as having the gantry out of line can cause the crane to crab and get stuck, as well as simply looking awful.
To ensure a perfect level to your gantry our engineers will take a datum point in your factory, then laser measurements are then taken in all directions to confirm
the column positions and height. The columns are then packed to ensure each has the same finished height.
