for aircrafthydraulicpneumatic

Description
The model 4505.91 is a 5 t, two-stage hydraulic tripod jack. Langa S line tripod jacks feature a compact, simple design that preserves all essential operational functions while enabling easy maintenance. The modular construction separates cylinder and frame, reducing maintenance costs and downtime, and facilitating rapid spare-part replacement. The jack is designed for long-term service on business and light aircraft and helicopters. Every unit is quality-checked on a jack tester before delivery. All models are laterally tested at 15% of the vertical load.
