(1) The passenger lift truck is equipped with four supporting legs, two on each side, each leg cylinder interface is installed with a two-way hydraulic lock, so that the passenger lift truck plays a stabilizing role.
Each foot cylinder interface is equipped with a two-way hydraulic lock to stabilize the passenger car.
(2) The legs are equipped with interlocking devices to prevent the vehicle from moving when the legs are not fully extended or retracted. And there is a locking device to prevent the retraction during the work and fully retracted when the state of the outstretched.
(3) The driver's cab is equipped with an indicator light for the position of the spreader feet, so that the vehicle cannot be started when the spreader feet are not retracted.
4）There are 2 supporting feet at the front and rear, and the supporting feet can guarantee the vehicle to work safely in the wind of grade 8 (20.7m/s), and keep stable in the wind of grade 12 (120km/h), and the safety coefficient of tipping over is 5.3.
