Study Notes

Cleaning Materials

Inspection areas must be clean and free of contaminants like dust and grease to ensure accurate assessments.
Basic cleaning materials recommended include rags, wire brushes, and pH neutral cleaning fluids.
Adhere to data sheets and chemical warnings, and integrate into the Job Safety Analysis (JSA)/risk assessment.

Types of Mobile Cranes

Rough Terrain Cranes

Designed for rough terrain, capable of "lift on rubber," meaning it can lift and travel with a load.
Outriggers should be extended and jacks lifted during function testing to enhance safety.

Thorough Examination

Conducted at specified intervals, before first use, after major repairs, and after incidents affecting crane integrity.
A competent person decides on any supplementary testing needed, such as non-destructive or overload testing.

Scope of Thorough Examination

Defined by the competent person for first use, following installation, and periodic examination.
Risk factors and previous inspection records must be considered.
Requirements should include operational checks, component inspections, and risk-based assessments of probable failures.
Supporting chassis and tyres are included in thorough examinations.
Level gauges must be clear and undamaged.

Power Take Off (PTO) Drive Shaft

Visually inspect the PTO shaft for security, condition, and engagement status.

Access Ladders

Check access ladders for damage, attachment fixtures, missing steps, broken welds, and missing bolts.

Thorough Examination – Crane Structure

Key areas to inspect minimally include:
- Manufacturer’s plate, serial number, model, and year of manufacture.
- Counterweight and counterweight attachment system.
- Operator cab and Remote Control Interfaces (RCIs).
- Boom cylinder and telescoping sections.

Manufacturer's Identity Plate

Verify the identity of the crane to ensure accurate load chart availability.
Serial numbers on the rated capacity charts should match those on the crane plate.

Boom Wear Pads

Movement in the boom observed during a sudden stop indicates wear pad condition; sideways movement suggests the need for adjustment or replacement.

Telescoping Systems

Older cranes may use multi-ram systems, while modern cranes often use single ram telescoping systems with a specific percentage of movement.
Examine for hydraulic leaks by checking for oil signs at the boom base; internal rams may not be directly visible.
