Product Overview：
SWL 4-ton spider crane is a compact yet powerful lifting solution that built for medium-duty lifting tasks that require both power and flexibility. Unlike standard cranes, this mini crawler crane is specially designed to operate in tight spaces, sloped surfaces, indoor facilities, and urban construction zones with limited access.
With a 4000kg lifting capacity, reinforced telescopic boom, stable hydraulic outriggers, and tracked chassis, SWL 4-ton spider crane delivers exceptional performance while maintaining a small footprint.
Widely used in curtain wall and glass installation, steel structure erection, machinery handling, indoor lifting operations, building renovation, bridge maintenance, and industrial plant projects, SWL 4-ton spider crane has become the preferred choice for construction teams, rental companies, and engineering firms worldwide. Its combination of strength, mobility, and safety makes it one of the most versatile lifting solutions in the small crane market.
Advantages & Features：
1. Enhanced Lifting Performance for Medium Loads
SWL 4-ton spider crane provides stronger lifting power than smaller models, making it perfect for handling heavier materials and equipment. Its optimized boom design ensures smooth extension and stable load control, even at maximum working height.
2. Narrow Access Capability with Strong Stability
