Mobile Elevating Work Platform
MEWP is a movable lifting device specifically designed for high-altitude operations. Its core function is to stably transport workers, tools, and materials to designated heights (usually from 3 meters to over 40 meters) via a mechanical structure, while providing a stable working platform at height.
Combining flexibility, safety, and efficiency, it widely replaces traditional tools such as scaffolding and ladders, and is suitable for diverse high-altitude scenarios including building decoration, municipal maintenance, equipment installation, and warehousing & logistics—making it a core piece of equipment for modern high-altitude operations.
MEWP can be categorized into multiple types based on its lifting structure, movement method, and application scenario. Different types have distinct functional focuses, accurately meeting various high-altitude operation needs:
1. Classification by Lifting Structure (Core Classification Method)
(1) Scissor Lift
Structural Features: Relies on the cross expansion and contraction of multi-layer scissor arms to achieve lifting, with a vertical lifting trajectory. After the platform is raised, it offers strong stability (supported by the triangular structure formed by the scissor arms), but has a small horizontal working radius (only operable directly above the equipment).
Lifting Height: Conventional models range from 6 to 18 meters; some large models can reach up to 24 meters.
Applicable Scenarios: High-altitude operations requiring "vertical height + fixed area", such as:
-
Decoration and lighting installation for ceilings in shopping malls/workshops;
-
High-altitude shelf cargo access in warehouses (used in conjunction with forklifts);
-
Municipal road street lamp maintenance and billboard installation (on flat ground areas).
(2) Articulating & Telescopic Boom Lift
Divided into "Articulating Boom Lift" and "Telescopic Boom Lift", its core advantage is the adjustable horizontal working radius, enabling "high-altitude obstacle-crossing" operations:
Articulating Boom Lift
Structural Features: Equipped with 1-3 foldable "articulated arms", it can flexibly adjust the lifting angle (e.g., first rise vertically, then extend horizontally to cross obstacles), and the platform supports 360° rotation.
Lifting Height & Working Radius: 10-30 meters in lifting height, 5-20 meters in working radius.
Applicable Scenarios: High-altitude operations requiring obstacle crossing, such as:
-
Exterior wall decoration of buildings (crossing windowsills and balconies);
-
Outdoor tree pruning (crossing ground greenery);
-
Inspection of bridge undersides (crossing obstacles beneath the bridge deck).
Telescopic Boom Lift
Structural Features: Adopts a single telescopic straight arm, offering a larger horizontal working radius (prioritizing "long-distance high-altitude operations") and faster lifting speed, but with slightly lower flexibility than articulating boom lifts.
Lifting Height & Working Radius: 15-40 meters in lifting height, 10-35 meters in working radius.
Applicable Scenarios: High-altitude operations requiring "great height + long radius", such as:
-
Steel structure installation in large workshops (with large high-altitude spans);
-
Maintenance of equipment on the top of airport terminals;
-
Replacement of large outdoor billboards (high height and far from ground obstacles).
