This crawler-mounted mini crane, commonly referred to as a spider crane, offers compact tracked mobility with high stability and hydraulic lifting capabilities. Powered by a diesel engine with electric start (optionally dual power electric/diesel), it incorporates telescopic booms, multi-section outriggers for leveling, and full 360° slewing. Its compact form factor allows it to operate in narrow spaces and confined job sites, yet it delivers lifting performance up to several tons—ideal for construction, mechanical installation, indoor/outdoor maintenance, and facade work.
