The VTL system was developed to combine the fast and accurate positioning of a fixed lead system with the hanging lead system’s ability to adjust the height of the lead base up and down.
High Torque Drilling Lead (H-Style)
Crane Mounted Leads designed for high torque usually associated with drilling applications, RC, conventional, auger shaft.
Piling Leads (Box and Spud Style)
Crane Mounted Leads designed for piling. Piling Leads come in either Spud ‘L’ or Box ‘BL’ form. Box and spud leads are often interchangeable however the ‘L’ Style is better suited to double as a drilling lead.
Systems for Railway Applications
Designed specifically to attach to railway cranes, these leads have been optimized for the installation of 12x74 piles for shoring, bridge abutments and piers in the rail industry.
fixed lead system is well suited to level job sites with few obstructions and has the advantage of fast positioning of the lead. The hanging lead is very adaptable to different elevations and batter piles but takes much longer to position.
The Vertical Travel Lead was developed to combine the advantages of fixed leads, fast and accurate positioning, with the ability to adjust the height of the lead base up or down. The VTL lead is connected to the boom by a sliding connection which allows the lead to be elevated or lowered below grade. Many have recognized the advantages of the VTL system, and they have become the Industry standard in Canada, US Railway Construction, and many parts of the USA. The structural column of the VTL will resist bending in forward, aft, and side batter positions.
