🏗️ What a Compact Crawler Boom Lift Is
A compact crawler boom lift — sometimes called a tracked spider lift — is a specialized aerial work platform mounted on moving tracks (crawlers), designed to work in tight, uneven, or constrained job sites where bigger machines can’t fit easily.
Key features:
-
Crawler tracks for mobility on uneven ground.
-
Articulated boom for flexible reach in vertical and horizontal directions.
-
Often used for access work (electrical, finishing, installation) at height on complex construction projects.
🏗️ Why It’s Used on Metro Projects
In large infrastructure projects like the MRT extension at Kamalapur, compact crawler boom lifts are likely used for tasks such as:
-
Installing electrical or signalling equipment on elevated structures.
-
Finishing work on station platforms or viaducts.
-
Accessing difficult-to-reach locations that large cranes or lifts can’t easily serve.
Because the site has many elevated beams, columns, and narrow working margins, these crawler boom lifts help crews safely reach work areas without needing a lot of space.
