The Cost of Doing It the Old Way
Never Let This Happen to an Intersection in Your State
Two bucket trucks, a crane, a full police escort, and a lane closure — just to swing one traffic signal out of the way for a single oversized load. This is the mobilization a Blacklaw Traffic Light Swivel Base eliminates.
We have the solution!
Featured Product
The Blacklaw Traffic Light Swivel Base
Moving a superload through an intersection used to mean cranes, bucket trucks, and hours of road closures. The Blacklaw Traffic Light Swivel Base lets one technician rotate the signal head clear of the load path in minutes — then swivel it back into place, with no rewiring and no permanent changes to the pole.
13"–27" Pole Fit
Fits standard 13" to 27" signal pole diameters with no modifications; custom sizing available on request.
One-Man Operation
A single technician can unlock, swivel, and re-lock the signal — no crane or bucket truck mobilization needed.
Tamper-Resistant Lock
Secure, padlockable operation keeps the assembly locked in place between scheduled superload moves.
Time & Cost Savings
Eliminate repeat crane and bucket truck mobilizations, reduce labor hours, and keep loads moving on schedule.
