Trailer Masts

Trailer Masts

At Site One we can provide trailer masts to suit any (reasonable) requirement. We have a wide range of standard designs, but we also provide a service to design and manufacture a trailer mast to your specification. The standard unit is a single axle braked trailer, all up weight is less than 1500kg so towable by a large car, medium size van or 4×4. Four adjustable jacks allow the trailer to be leveled. Where stability of the mast top is critical or with high headloads we recommend guying the mast and we can supply a guy set to match. All trailer masts are supplied as standard with:


  • Fully hot dip galvanised trailer and mast
  • Four levelling jacks, three on telescopic outriggers
  • Front mast support post adjustable in height to facilitate rigging the mast from the ground
  • Manual winches for tilt and telescope
  • 50mm ball coupling and 7-pin plug
  • Full lighting set
  • Licence plate holder
  • Overrun brakes with auto-reverse and handbrake
  • Adjustable jockey wheel



Tilt ‘N’ Telescope

The triangular lattice mast is made up of fully welded 6m long steel lattice sections mounted on a post, giving a ‘Tilt and telescope’ mast. Available as 2, 3, 4 or 5 section masts providing, with the standard extension pole, heights up to 30m Options include:

  • Electric Winches
