What is Mechanical Equipment work?

Mechanical equipment work covers installation, commissioning, maintenance, and repair of mechanical systems including automatic gates, garage doors with spring mechanisms, hydraulic and fluid power assemblies, load skate systems for heavy equipment movement, scaffoldless lift systems, and general equipment assembly. These activities combine mechanical, electrical, and structural hazards.

Why it matters

Mechanical equipment presents hazards capable of causing catastrophic injuries. Gate and garage door spring systems store significant energy and cause crushing injuries when de-energisation is not performed. Hydraulic systems at high pressure create hydraulic injection hazards. Load skate operations can crush workers if loads become unstable. WHS Regulations classify mechanical plant installation on construction sites as construction work requiring SWMS for high-risk activities.

Main hazards

  • Stored Energy Release from Springs and CounterweightsGarage door spring systems, automatic gate counterweights, and mechanical equipment store significant energy under tension or compression. Unexpected release during installation or maintenance without proper de-energisation causes severe impact and crushing injuries. Lockout-tagout procedures and spring tension management are critical controls.
  • Hydraulic Injection InjuriesHydraulic systems operating at high pressure can force fluid through pinhole leaks in hoses and fittings at velocities sufficient to penetrate skin. Hydraulic injection injuries appear minor initially but cause severe internal tissue damage requiring emergency surgical intervention. Never test for hydraulic leaks using bare hands.
  • Crushing During Load MovementLoad skate operations move extremely heavy equipment with limited clearances. Skate failure, load shift, or worker positioning errors can result in instant crushing injuries. Ground preparation, load calculations, exclusion zones, and coordinated team communication are essential safety controls.
  • Entanglement in Moving Mechanical PartsRotating shafts, chain drives, gear systems, and other moving mechanical parts in equipment assemblies create entanglement hazards. Loose clothing, hair, and jewellery can be caught by moving parts, causing degloving, amputation, and fracture injuries. All guards must be in place before testing mechanical systems.
  • Electrical Hazards During CommissioningAutomatic gates, garage doors, and powered equipment require electrical connection during installation and commissioning. Energised conductors during fault diagnosis and adjustment create electrocution risks. Appropriate electrical safety procedures, isolation, and qualified electrical worker involvement are required.

Questions

What qualifications are needed to install automatic gates in Australia?

Automatic gate installation requires a licensed electrician for all electrical connections including motor wiring and control circuits. Installers must be familiar with AS/NZS 60335.2.103 (Safety of household and similar electrical appliances - Automatic gate operators) which specifies entrapment protection requirements, safety edge functions, and force limitation. Some states require additional licensing for security-related access control systems. All installers should complete manufacturer training for the specific gate operator systems they install, as commissioning safety features correctly is a critical liability and safety requirement.

How do I safely handle torsion spring systems on garage doors?

Garage door torsion springs store enormous amounts of energy under tension and are extremely dangerous if handled incorrectly. Springs must only be adjusted or replaced using proper winding bars of correct length - never with screwdrivers or inappropriate tools. The spring must be fully unwound before any work on cables, drums, or bottom brackets. Never allow anyone to stand in line with the spring during winding or unwinding operations. Broken spring replacement must follow a complete sequence: unwind remaining tension, secure door in fully open position, replace spring, rewind to specified turns, and test thoroughly before releasing. Consider manufacturer training for spring work and using specialised spring replacement tools.

What ground preparation is required before load skate operations?

Load skate operations require a thorough assessment of ground bearing capacity before commencing. The combined weight of the load and skates must not exceed the ground's bearing capacity, which requires knowing both the load weight and the skate footprint area. Floors must be clean, free of debris, and level within acceptable tolerances for the skate system. Any floor penetrations, drains, or weak points must be identified and avoided or bridged. Load spreading plates may be required to distribute point loads from skates. On construction sites, structural engineers may need to certify that floor slabs can carry the load during moves. Document all ground assessment information in the SWMS.
