crane load charts
Crane load charts detail the features of the crane and how its lift capacity varies depending on distance and angle.
Riggers specialise in the lifting of heavy objects, often helped by a crane or derrick. They work with crane operators to attach and detach crane loads. They may also install the heavy object in place.

4 competencesinspect construction sites
Ensure health and safety during the construction project by inspecting the construction site regularly. Identify risks of putting people in danger or of damaging construction equipment.
interpret 2D plans
Interpret and understand plans and drawings in manufacturing processes which include representations in two dimensions.
secure heavy construction equipment
Secure heavy equipment such as tower cranes or concrete pumps before, during, and after use to prevent damage to the machines, workforce or construction site. Take precautionary steps such as retracting the robotic arm of concrete pumps or bringing the hook block back to the jib.
work in a construction team
Work as part of a team in a construction project. Communicate efficiently, sharing information with team members and reporting to supervisors. Follow instructions and adapt to changes in a flexible manner.

9 competencesfollow health and safety procedures in construction
Apply the relevant health and safety procedures in construction in order to prevent accidents, pollution and other risks.
green
follow safety procedures when working at heights
Take necessary precautions and follow a set of measures that assess, prevent and tackle risks when working at a high distance from the ground. Prevent endangering people working under these structures and avoid falls from ladders, mobile scaffolding, fixed working bridges, single person lifts etc. since they may cause fatalities or major injuries.
inspect construction supplies
Check construction supplies for damage, moisture, loss or other problems before using the material.
interpret 3D plans
Interpret and understand plans and drawings in manufacturing processes which include representations in three dimensions.
keep heavy construction equipment in good condition
Inspect heavy equipment for construction projects before each use. Maintain the machine in good working order, taking care of small repairs and alerting the responsible person in case of serious defects.
react to events in time-critical environments
Monitor the situation around you and anticipate. Be ready to take quick and appropriate action in case of unexpected events.
rig loads
Safely attach loads to different types of hooks and attachments, taking into account the weight of the load, the power available to move it, static and dynamic tolerances of all instruments and materials, and the mass distribution of the system. Communicate with the operator verbally or with gestures to ensure the safety and efficiency of the operation. Detach loads.
use safety equipment in construction
Use elements of protective clothing such as steel-tipped shoes, and gear such as protective goggles, in order to minimise risk of accidents in construction and to mitigate any injury if an accident does occur.
work ergonomically
Apply ergonomy principles in the organisation of the workplace while manually handling equipment and materials.

6 competencesguide operation of heavy construction equipment
Guide a colleague in operating a piece of heavy construction equipment. Follow the operation closely and understand when feedback is called for. Use communication techniques like voice, two-way radio, agreed-upon gestures and whistles to signal the appropriate information to the operator.
operate mobile crane
Operate a mobile crane safely. Take into account the condition of the terrain, weather conditions, load mass, and expected manoeuvres.
process incoming construction supplies
Receive incoming construction supplies, handle the transaction and enter the supplies into any internal administration system.
set up temporary construction site infrastructure
Set up a variety of temporary infrastructure used on building sites. Put up fences and signs. Set up any construction trailers and make sure that these are connected to electricity lines and water supply. Establish supplies stores and garbage disposal in a sensible manner.
test soil load bearing capacity
Test the capacity of the ground to support the load applied to it before installing heavy structures, such as tower cranes, or before driving on it with heavy vehicles.
transport construction supplies
Bring construction materials, tools and equipment to the construction site and store them properly taking various aspects into account such as the workers' safety and protection from deterioration.
Cross-sector
6 competenceskeep personal administration
File and organise personal administration documents comprehensively.
keep records of work progress
Maintain records of the progress of the work including time, defects, malfunctions, etc.
operate tower crane
Operate a tower crane, a tall crane used to lift heavy weights. Communicate with the rigger over radio and using gestures to coordinate the movement. Make sure the crane is not overloaded, and take into account weather conditions.
perform minor repairs to equipment
Conduct routine maintenance on equipment. Recognise and identify minor defects in equipment and make repairs if appropriate.
set up tower crane
Assist in the installation of a tower crane. Set the mast plumb and pour concrete onto the base to secure it. Bolt the mast into the concrete. Add progressively more pieces to the mast, usually using a mobile crane. Add the operators cabin on top of the mast and attach the jibs piece by piece.
use remote control equipment
Use a remote control to operate equipment. Watch the equipment closely while operating, and use any sensors or cameras to guide your actions.
