DRA Engineering has been designing and building the range of Humma Cranes since 1996. The range of cranes are 100% fabricated and assembled in our West Australian plant.

The original design brief came directly from industry consultation: Build the highest safe capacity, with longest fully powered boom and smoothest riding cranes available.

DRA has kept that original brief in mind to produce the 18T, 20T, 25T, 35T and now, the new 55T crane. Each model comes with class leading technology plus a range of industry firsts.

The focus on operator safety and comfort, low maintenance costs and high lifting capacity has made Humma cranes a market leader.

Humma Cranes

The Humma Advantage

Humma cranes are high performers, built for purpose to exacting standards.

  • Fully powered boom to 21.6M with digital rope compensation

    Fully powered and longest reach boom in their class. Digital rope compensation allows for easy winch rope changes.

  • Cummins ISC automotive engine

    Automotive spec ISC Cummins engine provides increased efficiency over industrial engines. Reduced fuel usage equals reduced running costs.

  • Airbag suspension

    Airbag suspension provides a smooth, quiet ride with excellent stability.
    The safest choice for high speed road use.

  • Low cabin noise levels

    Independent noise testing at below 85db(A). Extremely quiet cabin.

  • Fully featured, full width cabin

    Over sized AC system, 4 full colour cameras, large colour digital instrumentation display and separate LMI display. Dual air seats.

  • High Capacity Winch

    Large, full-capacity winch with grooved drum and tensioner.
    Designed for rated line pull in outer layer.

  • Dynamic load charts with stationary mode.

    Load charts dynamically calculate SWL for every individual position and articulation. Gives great flexibility giving operators the maximum lifting potential at each position. Stationary mode for extra capacity when not mobiling.


Humma Cranes are built in Western Australia to suit Australian conditions. They’re some of the toughest conditions on the planet which is why our cranes are made bigger, stronger and tougher.
