What are the application scenarios for straight-arm spider cranes and articulated-arm spider cranes respectively?

The core difference in application scenarios between straight-arm and articulated boom spider cranes stems from the difference in "operating range" and "flexibility" brought about by the boom structure. Straight-arm cranes emphasize "long-distance, open-field, and efficient operation," while articulated boom cranes emphasize "complex spaces, obstacle-surrounded areas, and multi-angle accessibility." Specific scenarios are as follows, and the appropriate model can be selected based on actual operational needs:

I. Core application scenarios of straight-arm spider cranes ("long distance, high altitude, and open space" are key)

The core advantages of a straight boom are its long horizontal reach and high vertical lifting efficiency, making it suitable for unobstructed high-altitude operations requiring wide coverage. Common scenarios include:

Large-scale construction work on building facade:

High-rise building exterior cleaning/painting, glass curtain wall installation and maintenance (requires crossing a wide space on the side of the building, no need to go around obstacles);

Installation of super high-rise billboards and LED screens (requiring a direct extension from the ground to a designated location at a high altitude, minimizing the operational radius).

Large-scale engineering/infrastructure maintenance:

Bridge underside and side inspection (requires long-distance span, avoiding the supporting structure beneath the bridge deck);

Installation of noise barriers on elevated roads and maintenance of tunnel roofs (open and unobstructed areas requiring efficient horizontal extension).

High-altitude operations in open areas:

Large factory roof maintenance (such as steel structure factory building and warehouse roof maintenance, in open areas without pillars obstructing the view).

Installation of high-altitude equipment in squares and stadiums (such as lighting and sound equipment, which need to cover a large area of high altitude).

Concentrated construction at a single work site:

Batch application of exterior wall coatings and laying of high-altitude pipelines (work points are concentrated on the same vertical or horizontal plane, eliminating the need for frequent angle adjustments).

II. Core Application Scenarios of the Articulated Boom Crane ("Wandering, Narrow, and Multi-Angle" are Key)

The core advantage of articulated booms is their foldable and flexible boom, making them suitable for scenarios with obstacles, confined spaces, or requiring multi-angle operations. Common examples include:

Obstacle swerving operation:

Indoor workshop equipment maintenance (requires bypassing machine pillars and production lines, reaching the top of high-altitude equipment through gaps);

Garden tree pruning and high-altitude greening maintenance (requires navigating through gaps in branches to precisely reach the designated branch location);

Work under the eaves/bay windows of a building (the scaffold needs to be bent and extended from below, avoiding the obstruction of the eaves).

Working in narrow/indoor spaces:

Indoor high-altitude maintenance in shopping malls and hotels (such as ceiling inspection, chandelier installation, and ventilation duct cleaning, which require passage through narrow doors/elevators and have limited space for outriggers to extend);

Construction work on the roof of underground parking garages (such as pipeline installation and fire protection facility maintenance, where the space is low and the passageways are narrow).

High-altitude operations in residential alleys (such as exterior wall repairs in old residential areas, where streets are narrow and traditional equipment cannot enter).

Irregular/Multi-angle working surfaces:

Construction of curved building facades (such as the maintenance of curved surfaces of stadiums and art galleries, which requires bending of the boom and rotation of the platform to adjust the angle);

High-altitude corner work (such as repairing the inside and outside corners of buildings, welding the side of equipment, and narrow angles that cannot be reached by a straight boom);

Maintenance of complex equipment (such as the top maintenance of power plant boilers and chemical reactors, which requires bypassing the equipment body to reach the maintenance point).

Scenarios with high environmental requirements:

High-altitude operations around hospitals and schools (small storage volume, low operating noise, and stable support in narrow spaces without affecting surrounding traffic).
