The MHH truss gantry crane is a lightweight, high wind-resistant, long-span special gantry lifting equipment. It is optimized and upgraded on the basis of the conventional MH gantry crane. The main beam and outriggers are designed with truss-type hollow steel structures. The equipment is equipped with national standard CD1 and MD1 electric hoists to complete the lifting operation. The overall weight is extremely light, the wind resistance is small, and the structural toughness is strong. It perfectly solves the pain points of large‑span gantry cranes such as heavy weight, poor wind resistance, and high wheel pressure. The equipment travels independently on ground tracks without relying on factory buildings. It is suitable for operation scenarios in large-span open-air storage yards, open construction sites, and sandy and windy areas. It is an economical and preferred equipment for large-span, light and medium-tonnage outdoor hoisting.

Core advantages

Compared with ordinary box-type gantry cranes, the MHH truss gantry crane has extremely outstanding advantages in adapting to long-span working conditions: the whole machine adopts a high-strength truss structure, which disperses the load through multi‑directional force distribution. The dead weight is greatly reduced, the overall toughness is stronger, it is not easy to deform, fatigue-resistant, and vibration‑resistant for stable long‑term long‑span operation. The hollow truss design has an extremely low wind resistance coefficient, and its wind resistance far outperforms conventional box‑type gantry cranes. It can stably adapt to harsh outdoor environments such as windy open air, sandstorms, and coastal strong winds, making operations safer; the overall wheel pressure of the equipment is small, and the load-bearing requirements for ground tracks and civil foundations are low, significantly reducing foundation costs. The foundation construction cost is low, the installation is convenient, the construction period is short, and the production efficiency is high; open‑web truss design delivers excellent site traffic clearance, does not affect the normal entry and exit of vehicles and materials, and the site utilization rate is high; the operating mechanism drives smoothly, starts and stops softly, and moves accurately, suited for frequent material loading, unloading, transfer and maintenance operations. Overload limiter, stroke limiter, buffer, anti‑collision device and emergency‑stop unit. Windproof rail clamps and anchoring devices can be installed outdoors. It supports dual‑mode operation: ground‑level operation and wireless remote control dual-mode operation. It can be upgraded with frequency conversion speed regulation and outdoor anti-corrosion and anti-rust configurations as needed to adapt to various complex outdoor working conditions.
