The HK120 is a 1.2-ton class miniature crawler crane engineered specifically for indoor and outdoor lifting in confined, low-passage areas where traditional cranes cannot operate. Its compact design (only 1.45m tall) and "spider-type" outriggers provide exceptional stability and maneuverability in tight spaces. With a maximum working radius of 5m and lifting height of 5.8m, it delivers versatile performance for construction, maintenance, and installation projects.
HK120 Mini Crawler Crane
The HK120 miniature crane is specially designed and manufactured for working in indoor or outdoor low-passage confined areas where traditional lifting equipment or truck-mounted cranes cannot be used due to their size . It is mounted on a double-track chassis with innovative “spider-type” outriggers that provide exceptional stability on various surfaces while maintaining a compact footprint .
The machine’s compact dimensions—L2095mm × W600mm × H1450mm—enable it to pass through standard doorways and operate in spaces with height restrictions . Despite its small size, the HK120 delivers impressive lifting capabilities with a maximum lifting height of 5.8m and a maximum working radius of 5m .
Standard equipment includes a comprehensive safety and control package: proportional valves for precise operation, a petrol engine, remote control with lamp, EMO (Emergency Stop) switch, and multiple safety systems including outrigger off-ground alarm with automatic stop, and a three-mode interlock system for walking/outrigger/boom operations . The hook is equipped with an anti-decoupling device, and both the slewing and winch systems feature brakes for secure operation .

🔹 Ultra-Compact Dimensions for Confined Spaces
With a height of only 1.45m and width of 600mm, the HK120 can pass through standard doorways and operate in low-clearance indoor environments where conventional cranes cannot access.
🔹 Spider-Type Outriggers for Maximum Stability
Innovative “spider-type” outriggers provide a wide, stable footprint during lifting operations while folding compactly for transport and maneuverability in tight spaces.
🔹 Double-Track Chassis for Smooth Mobility
The robust double-track chassis enables smooth movement across various indoor and outdoor surfaces, with black rubber tracks protecting floor finishes during indoor use.
🔹 Comprehensive Safety Systems
Multiple safety features including outrigger off-ground alarm with automatic stop, hook anti-decoupling device, EMO emergency stop switch, and three-mode interlock system ensure safe operation at all times.
🔹 Precise Proportional Valve Control
Proportional valves enable smooth, precise control of all crane functions, allowing operators to place loads accurately even in challenging confined spaces.
🔹 Remote Control Operation
Wireless remote control with integrated lamp enhances operator visibility and safety, allowing operation from the optimal vantage point for each lift.
🔹 Complete Braking Systems
Both slewing and winch functions are equipped with reliable brakes, ensuring load security during positioning and holding.
🔹 Enhanced Hydraulic Protection
Extra two sets of hydraulic filters extend system life and reliability, while balance valves on luffing and telescoping functions ensure smooth, controlled movements.
