Technical Data

Product Overview

Why Choose Compact Spider Crane for Confined Spaces?

Construction and industrial sites often face tight space limits where traditional cranes cannot access or operate safely.Our compact spider crane for confined spaces pairs an ultra-narrow footprint with a 6-section telescopic boom, enabling precise lifting in tight indoor/outdoor environments.The unit measures only L3.1m × W0.95m × H1.76m, weighs 2.7t, and easily passes through standard doorways for restricted-area work.

 How Does Dual-Power Spider Crane Improve Job Site Flexibility?

Job sites often lack reliable power, while engine-only models cause disruptive noise and emissions indoors.This dual-power spider crane features a diesel engine + 380V electric motor, enabling seamless indoor/outdoor operation switching.Equipped with a Changchai 380 diesel engine and customizable voltage, it delivers emission-free, quiet lifting in electric mode.

Key Performance Features

What Lifting Capabilities Does the 3t Mini Crawler Crane Offer?

Users need one machine to handle varied lifting heights, radii, and underground tasks without equipment changes. 3t mini crawler crane with 6-section boom delivers versatile lifting, with 11m max lifting height, 10.1m max working radius, and up to 40m underground stroke.Underground stroke supports 10m×1t (4 ropes), 20m×1t (2 ropes), 40m×0.74t (1 rope), covering full underground lifting needs.

How Does the System Boost 360° Continuous Slewing Spider Crane Stability?

Heavy lifting at extended radii or full rotation brings high tipping risks with inadequate support.

Hydraulic auto-support two-section outriggers create a stable base, while the 360° continuous slewing spider crane design enables smooth positioning without repositioning.Outriggers reach max extension of 4800mm×3610mm×4970mm, with full 360° slewing completed in 60 seconds.

Built for Productivity and Reliability

Can This Spider Crawler Crane for Construction and Maintenance Handle Complex Terrain?

Crane relocation on busy sites needs strong maneuverability and climbing ability for ramps and uneven ground.Hydraulic dual-speed travel system gives the spider crawler crane for construction and maintenance smooth movement and excellent climbing performance.Adjustable travel speed from 0 to 2.5 km/h, ensuring precise positioning in congested job site conditions.
