Manlift

Manlift periodic inspection is the at-least-annual examination and testing, by authorised engineers, of scissor and boom mobile elevated work platforms (MEWP) that carry personnel to working heights. The carrier structure, hydraulic lifting organ, platform safety equipment and control-electric systems are assessed. Roller or walkie platforms and self-propelled types are evaluated under the same scope. Because they carry people, these machines are examined with the strictest logic reserved for personnel-carrying machinery.

Components in Inspection Scope

• Scissor arms, pivot pins and bushings; chassis and counterweight
• Hydraulic lift cylinders, hose-line, tension valves
• Platform: guardrail, gate/chain, toe-board and standing surface, harness anchor points
• Controls: upper and lower boxes, proportional levers, emergency stop and limit devices
• Emergency descent system (manual valve or hand pump), levelling (outriggers) and pressure switches
• Electrical and battery: insulation, connector, BMS; wheel brake (on inclined types) and tilt sensors

Periodic Inspection Items

• Structural examination: Cracks and permanent deformation in scissor and chassis weld zones, pin-bushing clearance measurement, rust and impact traces. Guardrail height and closing direction are checked against the standard.
• Hydraulics: Hold-drift test at nominal load (two persons plus tools); hose and cylinder leaks; burst valve verification; functional trial of the emergency descent manoeuvre.
• Safety and control: Upper-lower limit, tilt sensor, overload and platform gate interlock test; emergency stop in control box; wheel brake and outrigger position switches.
• Electrical: Battery terminal oxidation, insulation resistance, cable gland damage, alarm-signal circuit and lighting.
• Function test: Full lift-descent cycle, driving-steering (on self-propelled) and brake stop control; presence of capacity plate and operator manual.

Legislation and Standards

As personnel-carrying work equipment, manlifts are subject to periodic control at least annually under Law No. 6331 and the Work Equipment Regulation; working-at-height procedures and operator licence (work machine authorisation) are administrative conditions. Technical references: TS EN 280 for mobile elevating work platforms, TS EN 1570-1 for low lifting platforms and TS EN 60204-1 for machine electrics. The regulation looks for the integrity of platform, guardrail, harness anchorage and the emergency descent chain.

Risks and Operator Recommendations

The scissor nip point and falling from the platform stand at the centre of incidents; therefore the gate-lock and harness anchorage rank high on the checklist, and corporate rules and audits must prevent the habit of boarding without a belt. Ground failure under outriggers and tipping on gradients become fatal when sensors are bypassed; the levelling indicator and pressure-switch functions must be tried every shift. Outdoors, wind speed must stay below the manufacturer limit and proximity to overhead power lines observed. Hose replacement and periodic oil control must be recorded per the manufacturer calendar.

Outcome

At the end of the control a signed report with structural, hydraulic and safety findings is issued. Manlift inspections are within our Lifting and Handling Machines service. For your working-at-height equipment see the Vehicle Lift page, or contact us for your programme.
