Excavator clamp with 360 degree rotation

The excavator's 360-degree rotating sleeper clamp transformsrailway constructiono and technical service all over the world. This specialized attachment transforms standard excavators into versatile rail maintenance machines, offering unprecedented flexibility and efficiency. Designed by industry leaders like Tiannuo Machinery, these durable clamps securely grip and manipulate railroad slats (also known as railroad ties) with precision while allowing full rotating motion. This 360-degree rotation feature allows operators to position sleepers at any desired angle, significantly reducing manual labor and improving installation accuracy. The TNHZJ75 is compatible with excavators from 20 to 60 tonnes and can handle a range of rail widths including 1000mm, 1067mm, 1435mm and 1520mm, making it an incredibly versatile solution for rail projects of all sizes.

Clamp and place sleeping bags at different angles

Versatile 360-degree rotation system

The defining feature of advancedexcavator clampTiannuo is its full 360 degree rotation capability. This engineering breakthrough allows operators to grip and place railroad shoes at virtually any angle required to position the rail. Traditional railroad maintenance often required repositioning the entire excavator or performing awkward maneuvers to achieve proper spike placement. With the rotating clamp system, operators can easily adjust the clamping angle while maintaining a stable excavator position. This flexibility is especially valuable when working on curved paths or in tight spaces where the excavator's movement is limited.

Adaptation to complex track geometries

Train tracks rarely follow completely straight paths. They bend, climb steps and navigate complex terrain, all of which require precise positioning of sleepers at different angles. The 360-degree rotation feature provides unrivaled adaptability when installing spandrels on curved sections of rail, where each spandrel must be placed at a slightly different angle than its neighbors. The TNHZJ75 excels in these challenging scenarios by allowing subtle adjustments that ensure perfect alignment with the curved track. Additionally, the rotation capability proves invaluable when working on railroad switches, crossings, and other specialized railroad components that require unique backrest configurations.

Multi-track compatible

Railroad systems around the world use a variety of routes, presenting a major challenge to equipment maintenance. The Tiannuo Sleeping Clamp solves this problem brilliantly with its multi-gauge compatibility, supporting standard measurements including 1000mm, 1067mm, 1435mm and 1520mm gauges. This versatility eliminates the need for rail operators to maintain separate equipment for different rail types. The 650mm clamp opening width accommodates a variety of span sizes, from narrow timber ties to the wider concrete spans used in high speed rail. Combined with 360-degree rotation, this gauge flexibility makes the mount an extremely adaptable tool for international rail contractors and maintenance teams.

Increased efficiency

Acceleration of installation time

The introduction of 360-degree rotatable excavator back clamps revolutionized railroad construction times. Traditional methods of installing sleeping bags often require multiple pieces of specialized equipment and significant manual labor, resulting in slow progress and increased project costs. With the Tiannuo valve mount, a single excavator can perform the entire sequence of operations - lifting, transporting, rotating and placing valves - without the need for additional machinery or excessive manual intervention. This simplified approach dramatically reduces installation time, allowing crews to install more tracks per day while minimizing labor requirements.

Reducing crew size

Labor costs make up a significant portion of the railroad construction and maintenance budget. The TNHZJ75 clamp significantly reduces the number of workers required on site, mechanizing what was previously a labor-intensive job. Where traditional methods may require a team of 6-8 workers to manually position and align clamps, an excavator equipped with a Tiannuo rotary clamp can perform the same tasks with just 1-2 operators. This reduction in labor not only reduces project costs, but also reduces safety risks by minimizing the number of personnel working on heavy materials and machinery. The precision of the mechanical clamp further reduces the need for manual adjustment, allowingcrews to workmore efficient.

Increased activity in limited areas

Railroad maintenance often takes place in challenging environments with limited access and confined spaces. The 360 ​​degree rotation feature proves invaluable in these tight work spaces, allowing the excavator to remain in a stable position while the clamp rotates to access difficult corners. This capability is especially useful when working on existing rail corridors where adjacent railroads remain in service, on overhead electrification systems, or near structures that restrict the movement of equipment. By providing precise backrest placement from a variety of approach angles, the rotating clamp maximizes operational efficiency in even the most confined work areas, reducing the need for rail possession time and minimizing disruption to rail service.

Protection of Sleepers

Preventing material damage during processing

Railroad slippersrepresent a significant investment, especially the modern concrete versions designed for high-speed rail. The specially designed excavator back clamp includes protective elements that maintain the integrity of the backrest during the processing process. Unlike conventional excavator mounts, which can damage backs due to improper gripping pressure or contact points, the TNHZJ75 Tiannuo model uses carefully designed clamping surfaces that distribute pressure evenly across the structure of the back. This thoughtful design prevents splitting, cracking, or structural weakening that could compromise the longevity or performance of the sleeper once installed. The precise clamp control system allows operators to apply enough pressure to secure the sleeping bag without risk of damage.

Ensuring Accuracy of Placement

The correct track geometry depends on the exact position of the backrest. The 360-degree rotation capability allows operators to achieve placement accuracy that would be difficult or impossible with fixed mounts. The clamp maintains a secure grip throughout the rotation process, preventing the backrests from shifting during positioning. This stability ensures that each sleeping bag is placed exactly where it is needed, maintaining the correct spacing and alignment required for tracking integrity. The TNHZJ75 design allows operators to make micro-adjustments to backrest positioning without releasing and re-engaging, further protecting backrests from potential damage that may occur during repeated handling attempts.

Long service life thanks to careful processing

Rail infrastructure is a long-term investment and sleepers are expected to provide reliable service for decades. By providing a gentle yet safe handling, Tiannuo's rotary clamp helps maximize the life of these critical components. Reducing physical stress during installation helps maintain the structural integrity of the sleeper and protective coverings or treatments. This careful handling is especially important for concrete bearings with embedded support systems or prestressed internal reinforcement that can be compromised by rough handling. By protecting backrests from installation damage, railroad operators benefit from reduced replacement frequency and lower life cycle maintenance costs—a significant benefit given the significant costs and disruptions associated with backrest replacement operations.
