Reliable performance in tight tunnels
The PK 700T delivers high lifting power in ultra-tight railway tunnels and subways. Engineered for maximum lifting capacity with a horizontally positioned boom, it safely maneuvers track segments up to 6.5 metric tons. Its compact, tunnel-optimized design enables efficient and reliable maintenance where operational uptime is essential.
The strengths of PALFINGER railway systems come to the fore when operating on sections of track with significant cant. State-of-the-art sensors integrate inclination data in stability calculations in real time. This allows the crane’s lifting capacity to be continuously controlled at inclinations from 0° to 15°, eliminating the need for general load reductions.
The Railway Premium line’s parametric lateral and vertical movement limiters provide maximum range of motion with the highest level of safety (PLd as defined in EN 13849). The limit curves are calculated based on the specific track and vehicle parameters and corresponding safety measures in accordance with EN 14033. Paltronic relies on state-of-the-art sensors for dynamic, real-time monitoring of the crane’s position to prevent unsafe movements. An optional feature permits storage of up to four different lateral limit curves and three vertical height limit curves.
The Paltronic crane control system and its connected sensor system achieve Performance Level d (PLd) as defined in ISO 13849-1 for all relevant safety features.
PALFINGER relies on highly flexible earthing cables to ensure excellent protection against electric shocks. Every component – from the base to the crane tip – is connected with 2×50 mm² earth cables. Transparent insulation allows easy inspection of the cables for breaks or carbonization damage caused by stray currents. Units equipped with a work basket are also equipped with corresponding earth cables.
