Effer Knuckle Boom Cranes from Altec

Discover the most versatile truck cranes in the world


With a lifting capacity ranging from 2 ton meters to 300 ton meters, Effer Knuckle Boom Cranes are a popular choice for construction, mining and marine industries and boast a power to weight ratio that is the best on the world market.

Effer cranes are all up to date with the newest safety technology available today. Some of these features include: radio remote control, overload & operator protection, manual & hydraulic swing up stabilizer legs and much more.

The design process incorporates the 50 years of experience to ensure the perfect balance between maximum performance, minimum weight and most importantly, operational safety. Effer has achieved something almost impossible: combine the lightness of its cranes with the unique power of their performances. Blending these two factors you have huge advantages:

  • Reducing structural weight without reducing strength = greater power available to handle the load;
  • Reducing structural weight = greater payload capacity on the truck;
  • Reducing structural weight = mounting of the crane even on smaller tucks

To ensure to performance of its cranes, Effer offers the following solutions:

  • Extensions come out in sequence
  • Use of the best Weldox steel
  • Design process with a background of 50 year history
  • Manufacturing process includes one piece boom sections with continuous inner and outer welding
  • Use of special materials for the manufacture of extension cylinders
  • Decagonal design for the second boom structure

Important Features From Effer Cranes

Precise Movements

Many Effer cranes employ rotation with a ring gear. This allows you to have continuous rotation of the crane in both directions. This performance is not achievable through the rotation with rack and pinion.

Saving Weight, Increasing Strength

Many Effer cranes have used Weldox high strength steel since 2001. This steel allows Effer to have the best power to weight ratio in the industry. Effer forms the steel into an exclusive ten sides, and then welds continuously inside and outside of the boom section.

Operator in Complete Control

Almost every Effer throughout the line-up has a radio remote controller available. On many models it is a standard feature. Some models offer a digital readout on the controller, which helps the operator to know the lifting parameters available.

Unsurpassed Stability

Effer has engineered the first “V” stabilizer and Cross Stabilizer system for folding cranes. It’s no longer required to use a front bumper stabilizer for capacity over the truck cab. Effer also offers a high strength steel self-supporting subframe that is applied directly to the truck frame on some models.
