The Crane Operator and Mobile Crane Operators operate mobile cranes to lift, move, position and place materials and equipment to a designated location. They calculate crane capacities and determine load weight, set up and dismantle cranes and position and stabilize the crane before the lift. They also perform some routine maintenance of the crane equipment such as lubricating and cleaning.


Safety is the number one concern of crane operators, owners and contractors. Occupational hazards include injuries resulting from power line contact, crane overload, falls, weather conditions or manual lifting.

Crane Operators and Mobile Crane Operators are required to take site-specific safety training to be familiar with the company, contractor and jobsite safety requirements. The regulatory environment in which Canada’s crane industry operates continues to grow with more complex issues such as due diligence and liability.


Mobile cranes are used in many different industry sectors such as the construction of buildings and the assembly of large equipment used on construction sites, warehouses, factories, mines, oil rigs, refineries, railway yards, ships and ports. Mobile crane operators may be employed by rental companies, construction firms, manufacturers, public utilities, transport sector companies, ship builders, cargo-handlers, airports, railways and mines.


There are many different types of cranes such as crawlers, truck-mounted, rough-terrain and all-terrain. The boom of the crane may be lattice or hydraulic. Some cranes are fitted with equipment that can perform specialized functions including pile-driver, clamshell, dragline, wrecking ball, magnet, heavy lift attachments, tower attachments and luffing jibs.


Some operators work for rental companies and rarely work on the same site more than once and routinely perform a variety of tasks with different types and sizes of cranes.


Crane operators and mobile crane operators work outdoors, often in noisy, dusty conditions. They work in various locations in all types of weather. Typically a 40-hour a week is normal, but overtime is usually required.


Industry Changes

The Crane Operator is constantly learning and updating their knowledge. As cranes are becoming more sophisticated, the need for training is increasingly important. Updated knowledge in computer technology, metallurgy and other areas associated with the engineering of crane equipment is beneficial to a crane operator’s career and safety.


Due to technological advances in operator aids such as Load Moment Indicators (LMI), crane operators are more aware of their crane operation limitations to increase safety and production.


Crane operation is becoming increasingly complex, so crane operators who have had educated training may find the most opportunities. Demand is also high for those who stay informed about new developments in this field.

Over the next five years, the employment outlook is considered to be excellent. The lack of trained and qualified technicians and the expected increased retirement rate in this trade over the next decade highlight the opportunities within the industry for good potential jobs.


Experienced crane operators and mobile operators may advance to supervisory positions, trainers, start their own business or set up their own crane rental businesses.



Safe working practices and accident prevention are the primary importance to the health and safety of all person(s) at any or all work place environments. All person(s) including employee, employer and government, share this responsibility in order to keep everyone free of any dangers or accidents that may cause an individual(s) serious bodily harm or death.


The Occupational Health and Safety Acts and Workplace Hazardous Materials Information System (WHMIS) Regulations, should be consistently reviewed and enforced in every work place environment. Educating and understanding these regulations is everyone’s responsibility in order to keep a safe work place environment.


Material Safety Data Sheets (MSDS) has contributed to a safer work place environment. Health and safety has become a high priority in the workplace due to increased awareness of dangers and the identifications of hazardous materials.


Practicing health and safety is a tremendous contribution to a safe and accident free work place environment.
