The assessment outline for the theoretical knowledge of crane drivers

Lifting machinery drivers are also called operators. They need to undergo theoretical knowledge training and assessment before taking up their posts, and they can only take up their posts with certificates after obtaining relevant certificates. The editor sorted out the scope of the theoretical knowledge assessment outline for crane drivers and shared it with everyone.

J1 professional basic knowledge

J1.1 The basic composition (structure, transmission, electrical, control, etc.), principle, purpose, working characteristics and requirements of the working environment of the crane.

J1.2 The main parameters of hoisting machinery .

J1.3 Requirements for main parts of lifting machinery.

J1.4 The function and use of various types of lifting machinery safety protection devices

Including lifting weight limiter, lifting torque limiter, lifting height limiter, stroke limiter, rotation limiter, amplitude limiter, overspeed protection device, deflection indicator or limit device, connection (connected) Lock protection device, anti-collision device, anti-wind and anti-skid device, buffer, wind speed alarm, limit torque limiter, landing door or parking railing and the connection (interlocking) of the cage, the emergency exit door on the top of the enclosed cage Safety switch, anti-falling safety protection device, anti-loosing rope and rope-breaking protection device, upper and lower limit switch, device to prevent people or vehicles from entering, entrance door, fence connection (interlock) safety inspection device, travel limiter and overtravel The function and use of safety protection devices such as stoppers, devices that prevent the carrier from falling, detection devices for parking in place, and devices for preventing falling off of trolleys.

According to the specific requirements of the corresponding crane, the previous safety protection device should be selected accordingly.

J1.5 The functions and requirements of the electrical protection system of cranes

Including the functions and requirements of short-circuit protection, zero-position protection, fault (open) phase protection, emergency power-off switch, electrical insulation, etc.

J1.6 Functions and requirements of hydraulic system.

J1.7 Judgment and protection of the safety status of foundations and tracks.

J1.8 Hoisting command signal .

J1.9 Lighting and signal.

J1.10 Safety technical requirements for lifting slings and rigging

Including the safety technical requirements for hooks, cross beams, hoppers, slings (ropes), binding cables (ropes), etc.

J2 security knowledge

J2.1 Duties and responsibilities of the crane driver .

J2.2 Safety management system for lifting machinery.

J2.3 Safety operating procedures for lifting machinery .

J2.4 Lifting machinery maintenance and daily inspection requirements

(1) Daily inspection, including inspection before operation, inspection after operation, filling in operation records, etc.;

(2) Maintenance, including confirmation of main parts such as hooks, wire ropes, brakes, safety protection devices, control devices, etc.

J2.5 Common failures of lifting machinery, identification of dangerous working conditions, and possible dangerous consequences of illegal operation.

J2.6 Scrap standards for クレーン部品.

J2.7 Safety knowledge of high-altitude operations.

J2.8 Knowledge of electricity safety.

J2.9 Fire and fire safety knowledge.

J2.10 Knowledge of preventing mechanical damage.

J2.11 Knowledge of toxic and hazardous working environment.

J2.12 The use of labor protection equipment.

J2.13 Safety signs.

J2.14 Emergency handling methods for emergency accidents of lifting machinery

(1) Identification of operating failures and abnormal conditions of hoisting machinery;

(2) On-site troubleshooting methods for common failures of hoisting machinery;

(3) Disposal of accidents (such as brake failure, etc.) of the hoisting machinery;

(4) Analysis of the causes of frequent accidents such as electric shock, fire, collapse, squeezing, and falling, and treatment methods for personnel protection, emergency rescue, emergency treatment and prevention, etc.

J3 regulatory knowledge

J3.1 "Special Equipment Safety Law of the People's Republic of China"

J3.2 "Special Equipment Safety Supervision Regulations".

J3.3 "Regulations on Safety Supervision of Lifting Machinery".

J3.4 "Measures for the Supervision and Administration of Special Equipment Operators".

J3.5 "Regulations for the Assessment of Special Equipment Operators."

J3.6 "Rules for the Management of the Use of Lifting Machinery".

J3.7 "Regulations for the Supervision and Inspection of Major Repairs in the Installation and Renovation of Lifting Machinery".

J3.8 " Regulations for Periodic Inspection of Lifting Machinery ".

J3.9 Other relevant specifications and corresponding standards.

The theoretical knowledge outline is only a scope, and there are many things to learn, but as a driver, you still have to understand these basic knowledge, which also has a lot to do with safe operation.
