The XSTO CT420SC is engineered for extreme-duty applications where both load capacity and control are critical. Positioned as the most advanced and versatile tracked stair climber in the range, it builds on the capability of the CT420 by introducing enhanced manoeuvrability and improved handling across both stairs and flat surfaces.
Designed with a crawler track system, the CT420SC maintains continuous contact with each step, ensuring smooth, stable movement while reducing impact on both the load and the staircase. This provides consistent, controlled handling of heavy, bulky, or sensitive equipment in challenging stair-access environments.
With a rated load capacity of 420kg, the CT420SC is suited to demanding applications such as vending machines, safes, industrial equipment, and precision machinery. Its intelligent load levelling system continuously adjusts the load angle during operation, maintaining a stable, upright position and significantly reducing operator effort when handling large or top-heavy items.
A key differentiating feature of the CT420SC is its integrated support wheel system, which add an extra layer of safety when exiting at the top of the stairs.
The unit is operated via a joystick or wired remote control system, allowing precise control of climbing speed, direction, and loading plate angle. Combined with automatic load plate adjustment, this enables operators to maintain safe and stable positioning of the load throughout the entire movement process.
Safety is further enhanced through non-marking, anti-slip rubber crawler tracks, ensuring reliable grip across a wide range of stair surfaces. The integrated braking and control systems allow the unit to securely stop and hold position at any point, providing confidence when handling heavy or high-value equipment.
Constructed from a reinforced aluminium alloy frame, the CT420SC is built for durability in demanding environments while remaining suitable for single-operator use.
Powered by a high-capacity lithium battery system, the CT420SC delivers extended runtime, capable of climbing approximately 1,400–1,600 steps (around 80–100 floors) on a single charge, supporting full-day operation with minimal downtime.
The CT420SC represents the most advanced and versatile tracked stair climber in the XSTO range, combining maximum lifting capacity with enhanced control, improved manoeuvrability, and superior real-world usability.
