Fixing faults early will almost always save you money in the long term, plus give you peace of mind that your equipment is safe for your staff to use.

WE CAN HELP YOU WITH ALL AREAS INCLUDING:

All truck-mounted cranes require an annual safety inspection. Multi Engineering provides certification-grade inspections and repairs, performed by trained professionals, for all knuckle boom crane brands.

Our inspection process is comprehensive and takes about six hours, including:

Cleaning and inspecting the crane structure, hydraulic systems, and controls.
Checking tightness of bolts and fasteners, especially those connecting the crane to the truck.
Inspecting the crane, sub-frame, and chassis for damage, cracking, or distortion.
Assessing the condition of paint and noting any corrosion.
Inspecting hoses, hydraulic fittings, oil tank, and fluid levels for damage or leaks.
Checking PTO, hydraulic cylinders, and stabilizer legs for issues.
Verifying crane stickers, load charts, and range diagrams.
Testing or replacing the crane hook with a certified hook.
Operating the crane to check wear and function of moving parts.
Testing lifting capacity and safety systems.
Performing a full load test for any creep or dropping.

If repairs are needed, we'll provide a quote and schedule follow-up work. After repairs, the crane is retested, and a test report or certificate is issued. We also conduct greasing and filter changes to ensure the crane is ready for work.

A copy of the inspection sheet, repair details, and hook test certificate will be provided.
