In the 2026 engineering landscape of Malaysia, Mechanical Unit Rigging (specifically for AHUs, chillers, and large HVAC assets) is a high-precision operation governed by the Energy Efficiency and Conservation Act (EECA) 2024 and the latest DOSH (JKKP) safety amendments. Since the full enforcement of the act on January 1, 2025, any structural distortion during rigging is a statutory liability—if the casing is "racked" or joints are compromised, the resulting air leakage will prevent the building from meeting its mandatory Energy Intensity Label.
At EKG (Malaysia) SDN BHD, our rigging protocols ensure that every mechanical unit is transitioned from the delivery bay to the plinth with the precision required to remain Sterile, Silent, and Statutory-Compliant.
Following the transition from the old PMA system on June 1, 2024, all rigging and hoisting operations must satisfy the updated Occupational Safety and Health (OSH) Act 1994 amendments.
Certificate of Fitness (CF) via MyKKP: Every lifting appliance (cranes, hoists, spreader beams) must have a valid CF visible on the MyKKP portal.
Competent Personnel: A legal rigging operation requires a DOSH-certified Lifting Supervisor, a certified Signalman, and a Rigger.
Method Statement & HIRARC: A site-specific Hazard Identification, Risk Assessment, and Risk Control plan is mandatory, detailing the safe system of work for high-rise or restricted-access zones.
Commercial mechanical units are sensitive thermal machines. Standard "choker" hitches can crush TB2 Thermal Break casings or flex internal IE5 EC Fan Walls, leading to "Energy Theft" through air leakage.
| Specialized Gear | Engineering Purpose | Benefit |
| Certified Spreader Beams | Ensures 100% vertical lift forces. | Prevents side-loading and crushing of AHU/Chiller panels. |
| Synthetic Soft-Slings | Non-marring, high-strength material. | Protects powder-coated finishes and thermal gaskets. |
| Dynamic CoG Analysis | Accounts for offset weight (coils/motors). | Ensures the unit remains perfectly level during the hoist. |
| Tag Line Precision | Dual-point synthetic tethering. | Manages orientation in KL's urban "wind canyons." |
As of January 1, 2026, the rigging process must be documented for the building's Digital Birth Certificate.
LOD 400 Path-of-Entry (POE): We utilize 3D simulations to verify that the unit will clear all structural beams and existing MEP services. This "Zero-Clash" approach prevents site delays and structural modifications.
Post-Rigging Stability Audit: Once "landed," we perform ultrasonic leak detection to confirm the lift did not compromise the unit's airtightness.
BIM LOD 500 Readiness: The as-installed rigging coordinates are uploaded to your building’s Digital Twin, providing the auditable evidence required for the mandatory 5-year periodic energy audit.
Technical Integrity: We are mechanical engineers who understand the thermodynamics of the assets we rig. We ensure your warranty remains intact by following manufacturer-specific lift points.
Urban Logistics Expertise: We manage all DBKL and PDRM permits for night-lifts and road closures in high-density areas like KLCC, TRX, and Bukit Bintang.
GITA Support: Our documented rigging and positioning reports serve as the technical proof needed to claim the 100% Green Investment Tax Allowance.
