This guidance document outlines the risks of operating scissor lifts and other mobile elevating work platforms (MEWPs) with outriggers on inclines. Positioning outrigger footplates on ramps and slopes can cause the MEWP to slide down the incline. The document provides recommendations to avoid this, including not exceeding the gradeability rating, placing braked wheels up the incline, and ensuring outriggers are lowered only onto firm, level surfaces capable of supporting the weight. A competent person must assess slope and surface conditions before setting up any MEWP on an incline.

EWPA Guidance Document – MEWPs with Outriggers on Inclines EWPA Guidance Document Outriggers on Inclines Rev3 Nov 2015 Page 1 of 2 The risks of operating Scissor lifts and other similar MEWPs on outriggers on inclines There is a risk of scissor lifts with outriggers (and other MEWP’s with outriggers) sliding down ramps, driveways, underground car park entry ramps and outdoor slopes. The contributing factors include newly painted ramps, icy, wet, oil and sand covered ramps, metal plates, grassy and loose surface slopes. This can occur when the platform is fully lowered or when elevated. Do not exceed the gradeability rating of the MEWP. Do NOT attempt to pack under the tyres. To avoid the MEWP sliding when setting up, place the braked wheels up the incline. (NB: Braked wheels should be identified, however if they are not identified, braked wheels are usually not the steer wheels - Refer to Operators Manual if not stated). The outrigger foot plates must be lowered only onto a firm surface that can support the load of the MEWP and its rated capacity. If the area above a sloped surface or ramp needs to be accessed, use a MEWP with the appropriate reach (e.g. a boom lift) so it can be set-up on a level area. A competent person shall assess slope and surface conditions before setting up machine on a slope. The positioning of outrigger footplates on ramps and slopes creates the risk of MEWP sliding down the ramp or slope. The positioning of outrigger footplates on stepped level surfaces (capable of supporting the MEWP) is acceptable. Braked Wheel Braked Wheel CORRECT INCORRECT

MEWPs with Outriggers on Inclines The EWPA recommends that a decal indicating ‘the risk of sliding down an incline’ is installed at the control position(s) on Scissor lifts and other MEWPs installed with outriggers. Place braked wheels up hill. (Braked wheels are usually not steer wheels – refer to Operators Manual) Do not exceed the gradeability of the MEWP. Lowering Outriggers onto sloped or slippery surfaces can result in the machine sliding and collision, crushing or tip-over. Death or serious injury could occur. A competent person shall assess slope and surface conditions before setting up machine on a slope. CORRECT INCORRECT Braked Wheel Braked Wheel WARNING OR-1 11/15
