Crawler Telescopic Mobile Crane is a high-performance lifting solution that combines the mobility and stability of a crawler crane with the flexibility and speed of a telescopic boom. It is specifically designed for heavy lifting operations on soft, uneven, and challenging ground conditions where high lifting capacity and precise load handling are required.
Mounted on a robust crawler undercarriage with wide steel tracks, the crane provides excellent ground pressure distribution and superior traction, allowing it to travel with loads and operate safely without the need for extensive ground preparation. The telescopic hydraulic boom, manufactured from high-strength steel, enables rapid boom extension and retraction, significantly reducing setup time compared to lattice boom crawler cranes.
The crane is powered by a high-efficiency diesel engine driving advanced hydraulic systems that ensure smooth, precise, and responsive control of hoisting, luffing, slewing, and telescoping functions. Equipped with modern load moment indicators (LMI), automatic safety cut-offs, and real-time monitoring systems, the crane maintains safe operation under varying load and outreach conditions.
Crawler telescopic cranes are widely used in infrastructure construction, wind energy projects, industrial installations, bridge works, power plants, shipyards, and heavy equipment assembly. Optional configurations such as fly jibs, counterweight variations, auxiliary hoists, remote control operation, and self-assembly systems provide additional flexibility for diverse lifting requirements.
Designed and manufactured in accordance with international standards such as EN 13000, CE, and ISO, crawler telescopic cranes offer an optimal balance of lifting performance, mobility, and operational efficiency, making them a versatile solution for demanding lifting applications in complex environments.
