Choosing the appropriate motor power for a tunnel lining trolley is crucial for efficient and safe operation. It involves considering various factors related to the trolley’s function, the tunnel’s characteristics, and the concrete lining process. Tunnel Lining Trolley Motor Power Selection 1. Functions of the Tunnel Lining Trolley and Associated Loads: A tunnel lining trolley typically performs several tasks, […]

Subway tunnel lining trolleys are essential non-standard equipment used in the secondary lining process of tunnel construction, especially for urban metro systems. Unlike the generic “tunnel lining trolley” which encompasses various applications (highway, railway, hydropower, etc.), subway tunnel lining trolleys are specifically designed to meet the unique requirements of metro tunnel sections and stations. Subway tunnel […]

Industrial steel structure construction is a highly systematic process used to build facilities like factories, warehouses, power plants, processing facilities, and large-scale workshops. Unlike traditional construction, it relies heavily on prefabrication, where major components are manufactured off-site in a controlled factory environment and then transported to the site for assembly. Industrial Steel Building Construction Process The […]

Industrial steel structures, while inherently non-combustible, are susceptible to significant strength loss and deformation when exposed to the high temperatures generated during a fire. This can lead to structural collapse, posing a severe risk to life and property. Therefore, fire resistance is a critical consideration in the design and construction of industrial steel structures. Fire resistance of […]

Steel structure factories are widely used in industrial settings due to their durability, cost-effectiveness, and quick construction. However, like any other structure, they require regular maintenance to ensure long-term performance, safety, and structural integrity. Proper maintenance prevents corrosion, structural failures, and operational disruptions, ultimately saving costs on major repairs or replacements. Steel Structure Factory Maintenance Maintaining […]

Shortening the construction cycle of steel structures is a critical goal for many projects, as it can significantly reduce costs and accelerate project handover. Here are some key tips and strategies to achieve this. Tips for shortening the construction cycle of steel structures I. Pre-Construction & Planning Phase: Early Contractor Involvement (ECI): Engage fabricators and erectors early […]

Slewing Bearing

A slewing bearing (or slew ring) is a large-diameter rotational rolling-element bearing designed to carry heavy, slow-turning, or slow-oscillating loads. It’s the critical component that allows massive machinery like cranes, excavators, and wind turbines to rotate smoothly and safely. The load capacity is the single most important parameter when selecting a slewing bearing. It defines the […]
