Positioning actuators on elevated work platforms — levelling mechanisms, outrigger extension drives, platform rotation systems — operate in a context where reliability is inseparable from operator safety. An actuator that drifts under load while a worker is positioned on an elevated platform is not a minor inconvenience; it is a safety-critical failure. The gearbox specification for this equipment needs to be approached with that context fully in view, working within whatever certification and safety standards apply to your specific platform design.
Ever-Power’s NMRV worm gearbox range is supplied into elevated work platform actuator applications across Australian construction and access equipment manufacturing, where self-locking position holding is one element within the platform’s broader certified safety system. This page covers the engineering considerations for this application, three industry examples, and direct answers to the questions equipment engineers raise when specifying platform actuators.
Elevated work platforms are subject to specific design standards and certification requirements that govern the complete safety system, not just the individual drive components within it. A worm gearbox’s self-locking property is a useful mechanical characteristic for actuator applications on this equipment, but its specification needs to happen within your platform’s overall certified design — confirmed against whatever standards and certification process applies to your specific equipment, in consultation with your platform design engineer or certifying authority.
| アクチュエータアプリケーション | 仕様の重点 |

| プラットフォーム水平調整機構 | 変動するプラットフォーム荷重下でも、正確かつ再現性の高い位置保持を実現 |
| アウトリガー延長駆動装置 | 構造荷重下における全伸長範囲でのトルクマージン |
| プラットフォーム回転システム | 回転範囲全体にわたって位置を自動ロックし、ドリフトなし |
An access equipment manufacturer was developing a new platform levelling system and needed an actuator delivering consistent, repeatable position holding across the platform’s full operating load range. NMRV040 was specified following detailed torque verification against the manufacturer’s full design load envelope, integrated into the platform’s certified safety design.
A construction equipment service provider needed replacement outrigger actuators for a fleet of existing elevated platforms, matched to the original equipment manufacturer’s specified torque and ratio for the platform’s certified configuration. NMRV050 units were specified to match the OEM requirement precisely.
A specialist platform manufacturer required a compact actuator for a platform rotation mechanism with tight structural envelope constraints in the design. NMRV030 fitted within the available structural clearance while delivering the torque required for the rotation system’s design load.
Access equipment manufacturers and platform engineers work with Ever-Power for the manufacturing consistency that underpins safety-relevant actuator specifications — over two decades of in-house production with tight tolerance control over the components that determine repeatable position holding under load. Our engineering team supports remote specification verification, confirming torque and ratio against your platform’s full design load envelope, with OEM configuration support for custom shaft and mounting requirements matched to your platform’s specific mechanical interface. Factory direct pricing applies across prototype development quantities through to full production volumes for certified platform designs.
We supply mechanical components with documented specifications and material certifications. Whether a specific gearbox configuration meets the certification requirements for your platform’s complete safety system depends on your platform’s own design certification process, which should be confirmed with your platform engineer or relevant certifying authority.
Provide your platform’s maximum rated load, the actuator’s mechanical advantage in your specific design, and required operating speed, and our engineering team will calculate the required torque and confirm the appropriate frame size and ratio with documented margin.
