Scissor Lift & Aerial Equipment Parts

The extending support structure is generally called a scissor mechanism or pantograph mechanism. It uses crossed support arms that open and close to raise or lower the platform. Hydraulic cylinders, pins, bushings, hoses and control components support the movement, so replacement parts must be matched to the lift design and application.

McCann builds custom hydraulic hose assemblies in shop or on site, including assemblies used with aerial lifts, cranes and utility trucks. The stated custom assembly range is 1/4 in to 1 in. Bring the failed hose or provide equipment details so the correct hose construction, end fittings and routing requirements can be confirmed.

Provide the failed hose as a physical sample whenever possible, along with the equipment model and application. The counter can identify hose length, end fitting types, bore, routing and the required construction. Also state the hydraulic fluid, operating conditions and circuit requirements so the replacement is selected for the actual system rather than bore size alone.

Yes. McCann states that custom hose assemblies can be fabricated in shop or on site using mobile service trucks. On-site fabrication can help when equipment cannot be moved or a large assembly is difficult to transport. Confirm availability, labour charges, exact specifications and scheduling details with the parts or service team before dispatch.

SAE J517 defines hydraulic hose constructions, while SAE J1273 covers selection, routing, fabrication, installation, storage and maintenance. The hose, fitting and crimp die should come from a matched manufacturer system so the assembly rating remains valid. Applicable OSHA lockout/tagout procedures require stored hydraulic energy to be controlled before work begins.

Do not search for a pressurised leak with your hand because escaping fluid can penetrate skin. Follow applicable lockout/tagout procedures, lower or secure the load, depressurise the circuit and use cardboard or another safe method to identify leakage. Keep replacement assemblies capped until installation and dispose of drained oil and scrapped hose under applicable waste rules.
