MEWPS (Mobile Elevated Work Platforms)
MEWPS stands for Mobile Elevated Work Platforms and includes scissor-lift, cherry pickers, order pickers.
A scissor-lift is a type of platform that can usually only move vertically. The mechanism to achieve this is the use of linked, folding supports in a criss-cross “X” pattern, known as a pantograph (or scissor mechanism). The upward motion is achieved by the application of pressure to the outside of the lowest set of supports, elongating the crossing pattern and propelling the work platform vertically. The platform may also have an extending ‘bridge’ to allow closer access to the work area, because of the inherent limits of vertical-only movement.
The contraction of the scissor action can be hydraulic, pneumatic or mechanical (via a lead-screw or rack and pinion system). Depending on the power system employed on the lift, it may require no power to enter ‘descent’ mode, but rather a simple release of hydraulic or pneumatic pressure. This is the main reason that these methods of powering the lifts are preferred, as it allows a fail-safe option of returning the platform to the ground by release of a manual valve.
What is MEWPS – Cherry-pickers/self-propelled boom?
The cherry-picker has a diverse number of uses and is an integral part of many construction and engineering environments. A cherry-picker is important to use of any task which is at heights. Safety is paramount when carrying out jobs above ground level and a cherry-picker means that the person carrying out the job can do so in safety and security.
A cherry-picker could be used to assist with any number of important jobs within, for example, the following areas including building maintenance, warehousing maintenance, construction sites, servicing telephone and electricity poles, fire services, and airports and shipyards, etc…
A cherry-picker is one of the most important pieces of equipment when working at height and its uses and application continues to grow as different industries recognise it uses and benefits.
