200t Overhead Crane Design for Megaprojects
Double-girder structure
The 200-ton super-heavy bridge crane adopts a heavy-duty double-main beam core structure, and some high-end engineering models adopt a four-beam and four-rail double-trolley reinforced structure, which completely subverts the carrying limit of ordinary double-girder cranes.The main beam adopts an integral welded box structure and uses Q420B high-strength alloy steel, which has the core advantages of high strength, high toughness, fatigue resistance and deformation resistance.The symmetrical layout design of the double main beam can evenly disperse the heavy-duty pressure of the 100-ton class, eliminating the problem of uneven force on the single beam and bending and deformation of the main beam.The structure has been optimized by finite element stress analysis, and the bending moment, shear force, and impact force during heavy-duty hoisting are strengthened in all directions. The rigidity of the whole machine is stronger, and the deflection deformation under no-load and heavy-load conditions is controlled within the minimum range of industry standards to ensure the structural stability of long-term high-intensity operations.

The complete lifting mechanism has been designed with heavy-duty reinforcement and can withstand long-term impact operations with a rated load of 200t.The wire rope adopts a multi-layer winding and wear-resistant configuration, with anti-slotting and anti-wear protection devices, which greatly improves the service life of lifting accessories.The lifting system adopts hydraulic synchronous lifting technology, multiple lifting points work together, and the synchronization error is strictly controlled within 0.1mm, which can realize the overall smooth lifting of ultra-large components, and avoid the deformation of components and the tilt of hoisting caused by excessive single-point force.At the same time, the mechanism has overload self-locking and power-off protection functions, which can be locked instantly under sudden working conditions to eliminate the risk of heavy objects falling, and is suitable for all kinds of ultra-high-risk heavy-duty hoisting operations.
Load distribution design
In view of the problems of load concentration and local force exceeding that are prone to 100-ton heavy-duty hoisting, the 200t super heavy-duty bridge crane is equipped with a scientific load distribution design.Through the structural logic of symmetrical force on the double main beam, balanced load-bearing at multiple lifting points, and multi-point force transmission of the trolley, the concentrated load is evenly dispersed to the structure of the whole machine and the track foundation to avoid overload damage to the local structure.Cooperating with customized spreader beam, it can convert single-point hoisting loads into multi-point uniform forces, completely solving the problems of uneven force, local deformation, and tilt offset of large planar components and ultra-long and overweight bridge cranes during hoisting, and greatly improving the safety and component integrity of heavy-duty hoisting, especially suitable for precision heavy-duty components, large hull segments, and large steel structure modules. Lifting protection needs.
Structural reinforcement

Custom Spreader Beams for 200t Overhead Cranes
Spreader beam capacity
The customized distribution beam is the core supporting system of the 200t super heavy-duty bridge crane. It is specially developed for extreme heavy-duty hoisting of 200 tons. The rated carrying capacity exactly matches the host load, and can stably withstand 200t static load and dynamic impact load. Sufficient safety redundancy coefficient is reserved, which far exceeds the industry's general safety standards.The beam has undergone professional load verification and can be adapted to various complex hoisting conditions such as full load, partial load, dynamic load, etc., to eliminate the risk of deformation, fracture, and instability of the beam.In view of the special lifting needs of oversized parts, the reinforced beam can be upgraded to improve the impact resistance and deformation resistance, and meet the lifting and carrying requirements of ultra-long, ultra-wide, and overweight special-shaped components.

Beam dimensions
The size of the distribution beam supports 100% non-standard customization, and can be accurately matched according to the length, width, weight, shape and structure of the hoisting components.The beam length interval of the conventional 200t crane is 6m-20m, and the cross-section height and width are optimized according to the carrying stress, taking into account the structural strength and lightweight characteristics, so as to avoid excessive beam weight and increase the load of the bridge crane.All beam sizes are optimized based on finite element simulation calculations, and customized for hoisting scenarios with different spans and different hoisting point spacing, which not only ensures the overall structural rigidity and carrying stability, but also avoids the waste of working space caused by dimensional redundancy, and is perfectly adapted to the exclusive hoisting needs of various large bridge cranes, steel structure modules, and hull segments.
Lifting point design
The customized distribution beam adopts a multi-hanging point modular design, and comes standard with 4 hanging points, 6 hanging points, and 8 hanging point layout. The spacing and force angle of the hanging points can be flexibly adjusted according to the structure of the workpiece, completely solving the disadvantages of single-point and double-point hoisting force concentration.The hanging point adopts high-strength forged lugs, one-piece molding without welded joints, stable load-bearing performance, and strong tensile and fracture resistance.The spacing of the hoisting points can be freely adjusted, supporting a variety of symmetrical and asymmetric hoisting layouts, and adapting to the hoisting needs of rectangular, special-shaped, ultra-long and overweight workpieces, effectively avoiding the tilt, distortion and deformation of the workpieces during the hoisting process, and ensuring the hoisting accuracy and integrity of precision heavy-duty components.
Load stability
The core value of customized beams is to greatly improve the load stability of heavy-duty hoisting. Through multi-point balanced force, lateral limit, and torque balance design, they can effectively offset the interference factors such as inertial shaking, wind offset, and load deviation during hoisting.Compared with the traditional direct hoisting method, with a customized beam hoisting system, the shaking amplitude of the workpiece is reduced by more than 85%, and the horizontal offset is controlled at the millimeter level.In high-altitude, long-span, and long-distance transportation operations, the horizontal stability of the workpiece can always be maintained, the problem of swing collision and position offset can be eliminated, and the accuracy of alignment and installation of large components can be greatly improved.
