Rigger jobs in Finland
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.
Rigger - Which skills are essential?
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.
Apply ergonomy principles in the organisation of the workplace while manually handling equipment and materials.
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.
Understand machines and tools, including their designs, uses, repair, and maintenance.
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.
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.
Check construction supplies for damage, moisture, loss or other problems before using the material.
Terms for lifting equipment, lifting accessories, slings, shackles, wires, ropes, chains, cables and nets.
Understand crane load charts which detail the features of the crane and how its lift capacity varies depending on distance and angle.
Apply the relevant health and safety procedures in construction in order to prevent accidents, pollution and other risks.
Interpret and understand plans and drawings in manufacturing processes which include representations in three dimensions.
Monitor the situation around you and anticipate. Be ready to take quick and appropriate action in case of unexpected events.
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.
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.
Interpret and understand plans and drawings in manufacturing processes which include representations in two dimensions.
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.
Rigger - Which skills are useful but not essential?
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.
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.
Use a remote control to operate equipment. Watch the equipment closely while operating, and use any sensors or cameras to guide your actions.
File and organise personal administration documents comprehensively.
Operate a mobile crane safely. Take into account the condition of the terrain, weather conditions, load mass, and expected manoeuvres.
Receive incoming construction supplies, handle the transaction and enter the supplies into any internal administration system.
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.
Conduct routine maintenance on equipment. Recognise and identify minor defects in equipment and make repairs if appropriate.
Understand the principles of electricity and electrical power circuits, as well as the associated risks.
Maintain records of the progress of the work including time, defects, malfunctions, etc.
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.
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 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.
