Slow down road block

Deceleration slope type traffic blocking roadblock Sun Yaru:
Length 3-meter, width cm, thickness cm Voltage power: Nail removal time: .3 seconds Continuous power-on time: hours Tire pin spacing Maximum load capacity: tons Tire pin height The long-life deceleration slope-type automatic tire puncture device has two forms: automatic and manual. The shape is made of high-quality steel plates, which are directly bent and welded. There are reinforcing ribs inside. There is no transverse transmission shaft. There are grooves and tire puncture needles on the transmission shaft. There are no vent holes on the tire puncture needles. When the vehicle forcibly breaks into the post, the tire puncture device will be automatically activated (it can also be done manually). When the tire breaker is in working condition, the tire puncture needle stands up and pierces into the tire. The tire lifts the tire puncture needle from the axle, and the air hole in the tire puncture needle is instantly deflated, making it impossible for the vehicle to escape. After use, close the gear lever or control button, the tire puncture needle will automatically reset back to the housing, and the following vehicles can pass normally. When a vehicle follows a vehicle and rushes into the post, the toll collector has enough time to let go of the vehicle in front and activate the car tie-down device to prevent the following vehicle from running through the post and escaping, thus achieving the purpose of blocking the vehicle.
