A crane that cannot pass through the site entrance can delay an entire lifting job. Factory renovations, glass installation, and indoor machinery replacement often leave little room for large cranes. A Tracked Spider Crane combines a crawler chassis with a telescopic boom for lifting work in restricted areas. Doorway dimensions, floor conditions, and the available setup area all affect site access.

Mini Spider Crane for Indoor Lifting


Factory retrofits often involve narrow passages, installed production lines, and low overhead structures. Curtain wall projects bring a different challenge: crews need to position lifting equipment close to the building without obstructing nearby work.
A mini spider crane suits projects where access space limits the use of larger lifting equipment. The YG-3 has an overall width of 980 mm, making it worth considering for narrow access routes. The wider YG-5 and YG-8 require more room for entry and turning.
Measure the access route before delivery. Include doorway clearance, overhead pipes, floor thresholds, and corners. Also plan the crane’s working position, as the outriggers need sufficient space to deploy.
Rubber crawler tracks reduce direct contact with the ground compared with some steel-track designs. They do not guarantee a mark-free floor, however. Dust, small stones, and tight turns can damage finished surfaces. Protective mats may be necessary on polished concrete or tile.
Telescopic Boom and Hydraulic Outriggers
The telescopic boom reaches beyond the chassis. A slewing mechanism turns the boom toward the lifting point, while the hoisting system raises and lowers the load. Hydraulic outriggers support the crane during lifting.
All three models use a five-section boom. The YG-3 extends from 3.1 to 9.2 m. The YG-5 and YG-8 have a listed boom length of 12.3 m. Continuous 360-degree slewing allows the operator to reposition the boom where surrounding structures leave enough clearance.
The four-fall rope system handles hoisting. The YG-5 and YG-8 list a hoisting speed of 12 m/min, while the YG-3 lists a range of 0–8 m/min. Rigging and load positioning also affect the time required for each lift.
Spider Crawler Crane for Curtain Wall and Factory Projects
Glass and Curtain Wall Installation
Curtain wall contractors frequently face restricted access around finished building façades. A Tracked Spider Crane can lift glass toward the installation point when the load and working radius match the machine’s rated capacity. Glass-handling equipment, wind conditions, and clearance beside the building also matter.
Factory Machinery Replacement
Existing production lines leave little room for machinery removal. A compact crawler crane can enter through a suitable route and lift motors, pumps, and machinery assemblies into position. This arrangement suits factory retrofits where columns, equipment, and building structures restrict movement.
Indoor Renovation and Maintenance
Warehouses, commercial buildings, and industrial facilities often need lifting work around existing structures. Verify ceiling clearance, floor load capacity, and outrigger layout before indoor lifting. Ventilation and operating noise also require attention, particularly in occupied buildings.
Municipal and Construction Work
Building extensions and confined construction sites can limit access for larger lifting equipment. A spider crawler crane offers crawler-based movement and a telescopic boom for lifting on suitable ground. Contractors can use it for selected installation, maintenance, and construction jobs.
Choosing a Compact Crawler Crane
The rated capacity is only one part of the decision. Working radius, lifting height, machine dimensions, and transport weight also matter.
- YG-3: Its 980 mm width and 2700 kg weight make it worth considering for projects with narrow access routes and transport limits.
- YG-5: This 5-ton model has a listed maximum working radius of 14 m at a 0.5-ton load.
- YG-8: This 8-ton model has a listed maximum working radius of 16.5 m and a maximum lifting height of 18 m.
For trailer transport, check the crane’s weight, dimensions, loading method, and local transport rules. These details help determine suitable transport equipment and loading arrangements.

FAQ
What lifting capacities are available?
The range includes 3-ton, 5-ton, and 8-ton models. The required load and working position determine which model fits the job.
Can a Mini Spider Crane work inside a factory?
Yes, when the access route, overhead clearance, floor conditions, and outrigger layout suit the machine. Indoor sites also need adequate ventilation and suitable noise control.
Is it suitable for curtain wall installation?
Yes. The load weight, lifting height, working radius, and glass-handling equipment must match the project.
Will rubber crawler tracks protect finished floors?
Rubber tracks reduce direct contact with the ground but do not guarantee a mark-free surface. Check the floor material and use protective mats where necessary.
