Safety code for lifting large equipment
1 Scope
This standard specifies the lifting organization and lifting preparation of large
equipment, the installation and use of mast cranes, the installation and use of hydraulic
lifting (jacking) gantry cranes, the use of mobile cranes (crawler cranes, tire cranes,
truck cranes), the lifting process control, the emergency management and other basic
requirements for safe production.
This standard applies to the lifting of large equipment in newly built, renovated
(expanded), overhauled oil field ground projects, onshore petroleum and chemical
engineering projects.

3 Terms and definitions
The terms and definitions established in GB 50798-2012, as well as the following terms
and definitions, apply to this document.
3.1
Lifting large equipment
The lifting process (hereinafter referred to as "lifting") of equipment (generally
referring to towers, reactors, modules, components), which has a mass greater than
or equal to 100 t or a one-time lifting length or height greater than or equal to 60 m.
3.2
Tensile connection plate
A plate component, which is used to connect the hook and the lifting eye of the lifted
equipment. It usually uses a shaft as the connecting member.
3.3
Flange connected lug
A lug type which uses the flange on the lifted equipment as a connecting piece to fix
to the equipment, which is usually a welded piece or a forging.
4 Lifting organization and responsibilities
4.1 A lifting organization structure shall be established for lifting, with a general
commander, the lifting technical person in charge, the responsible engineer for lifting,
a lifting commander, and a safety supervisor.
4.2 The job responsibilities of the lifting organization include:
- General commander: Fully responsible for the lifting work and overall responsible
for the safety and quality of the lifting;
- Lifting technical person in charge: Responsible for organizing the preparation of
large equipment lifting technical plans and responsible for review;
- Responsible engineer for lifting: Responsible for the preparation and
implementation of lifting plans (measures);
- Lifting commander: Responsible for the correct implementation of on-site lifting;
- Safety supervisor: Participate in the review of lifting plans (measures); be
responsible for safety inspection and supervision of on-site lifting.
5 Lifting preparation
5.1 General requirements
5.1.1 Lifting operators shall hold certificates when working.
the original approval procedures shall be re-approved.
5.2.2 When a new process or method is adopted for the first time, it shall be reviewed
and approved by the technical person in charge of the enterprise.
5.2.3 Technical measures for lifting shall include but not be limited to the following:
- Project overview;
- Basis for preparation;
- Main parameters of equipment, components and lifting process methods;
- Calculation of stress in lifting process;
- The composition and job responsibilities of lifting operators;
- Technical, quality and safety requirements;
- Risk analysis and emergency plans;
- Summary table of lifting equipment and rigging;
- List of materials used for construction methods;
- Lifting process flow chart;
- Design drawings and calculations of self-designed slings and facilities, including
lifting lugs, tensile connection plates, connecting shafts, spreader beams,
reinforcements, etc.;
- Lifting floor plan, etc.
5.2.4 The force calculation shall include but not be limited to the following:
- Calculation of loads;
- Calculation of the location of the center of gravity of the equipment;
- Stress calculation in the lifting state (process) of the equipment, selecting
machinery and rigging according to the maximum stress and calculating the safety
factor;
- Verification of crane foundation bearing capacity;
- If necessary, verification of the entire or partial equipment and components.
5.2.5 The lifting floor plan shall include but not be limited to the following:
wire rope. Generally, the diameter of the winding drum shall be 16 to 25 times the
diameter of the steel wire rope.
5.3.4.4 When multiple winches are used to lift equipment, their traction speed and
lifting capacity shall match.
5.3.4.5 When multiple winches are used to lift equipment, each winch shall be equipped
with a separated switch.
5.3.4.6 The insulation resistance of electrical equipment such as motors shall be greater
than or equal to 0.5 MΩ.
5.3.4.7 The braking device of the winch shall be safe and reliable.
5.3.4.8 The resistance value of the winch protective grounding shall be less than 10 Ω.
5.3.5 Pulley (block)
5.3.5.1 The pulley (block) shall be used according to its rated lifting capacity. When the
pulley block is used partially, the load shall be reduced in proportion to the
corresponding number of pulleys.
5.3.5.2 Before use, the pulley grooves, axles, splints, hooks, rings, suspension beams
and other parts shall be inspected for defects such as cracks, damage, deformation.
5.3.5.3 The selection of the pulley (block) and the wire rope shall match. The diameter
of the pulley shall usually not be less than 16 times the diameter of the wire rope; the
inclination angle of the wire rope entering the pulley groove shall be less than 15°.
5.3.5.4 The minimum clear distance of the pulley block shall not be less than 5 times
the wheel diameter.
