This is the basic structure to support the TTC 280 crane pedestal and is considered the mobile pedestal system. The structure consists of welded box beams to ensure rigidity, stability, and easy inspection and maintenance. The pedestal part is made of steel with a yield strength of ≥235 N/mm², a tensile strength in the range of 373-480 N/mm², and a relative elongation of 24% or equivalent. Before welding, the welding procedure is certified and follows approved processes or drawings.

The steel structure consists of three parts: the main beam, pedestal, and pedestal beam described as follows:

The main beam is designed in a box shape to ensure rigidity, good bending and torsional resistance, and lightweight. On the river side of the beam, a tube is welded with a thickness and diameter corresponding to the crane’s connecting tube (Adapter). This connecting tube goes into the main beam, connecting the upper plate and lower plate of the beam. The lower part of the beam is connected to the feet by welding.

Welding the pedestal to the crane connecting tube ensures concentricity and alignment of the crane’s connecting tube axis.

The pedestal has a box shape, and a triangular shape to ensure rigidity, compactness, and aesthetics. The pedestal includes the land-side foot part and the water-side foot part. The pedestal structure is assembled with the main beam. The main beam and pedestal are designed with crawl holes to allow workers to enter for structure inspection and maintenance.

Stairs run along the land-side foot, wide enough to reach the top of the main beam, into the crane column, and up to the crane cabin. Additionally, access can be made inside the pedestal to inspect, and store equipment, and steel structures. The stairs have sturdy handrails. The top of the main beam is equipped with a safety handrail. The tubes used for handrails and handrails are galvanized steel tubes. The operating floor, walkway, stairs, and protective rails are hot-dip galvanized according to QCVN or equivalent.

The steel structure is supported by a system of wheel assemblies that can move on rails. The entire crane is supported on wheels, and installed in a system of multiple balance beams to ensure that the crane load is evenly distributed over all wheels. Electric motors provide the drive for the wheels to operate well in wind conditions of 20m/s.

Wheels are designed for A100 rails. The wheels are made of cast S45C, and the working surface hardness is 38~42HRC. The axles are made of S45C steel or equivalent. Friction-resistant bearings with lubricating grease are used. Wheels, wheel axles, and bearings are of the same size for easy replacement and assembly.

The drive system is a motor coupled to a gear reduction unit. The three-phase electric motor has high starting torque and stable operation, coupled with a sealed reduction unit lubricated with oil, ensuring high transmission efficiency. Each motor is equipped with electronic brakes. This brake system will automatically act when power is lost, ensuring safety when the boom needs to stop. The brake system will release automatically when power is restored.
