Tire drag printing is affected by many factors such as tire pressure, width, tread pattern wear, and friction coefficient of the road; whether the vehicle is biased is balanced with its chassis suspension mechanism and mechanical wear of steering and steering systems. The degree is closely related, neither of which can truly reflect the performance conditions of the vehicle's braking system, but can only describe the braking performance from the side. The percentage of the front axle braking force and the axle load must be greater than the ratio of the front axle braking force to the axle braking force of the left and right wheels in the entire braking force growth; the front axle shall not be greater than +, and the rear axle shall not be greater than the vehicle's Braking performance, the main evaluation index is the braking distance of the car, the braking deceleration of the car and the braking time of the car. Its performance is closely related to the braking torque acting on the brake wheel, and The time from the lower brake pedal to the wheel brake reaching the rated braking torque is related to the latter. Due to the design factors of the vehicle construction, the latter is often not of much variation. The main indicators for evaluating the braking stability of a car are the ability to maintain linear motion while the car is braking, or the ability to drive along a prescribed curve. However, in actual operation, when the car is in emergency braking, it can still be difficult to do according to the driver's wishes to follow the car's safety detection in the corner of the modern traffic management. At present, the counter-forced drum brake test benches widely used in automobile safety inspection stations, automobile manufacturing plants, and maintenance stations measure and indicate the braking force by using the method of measuring the balance force against the rotation direction of the drum when the vehicle is braking. A device.
Construction Hoist:
Construction Hoist is divided into Material Hoist and Passenger Hoist.
Construction Hoist by hanging cage, driving mechanism, standard section, attachment, chassis, fence, electrical system and so on, which is often used to carry builders and building materials.
Because of its unique enclosure structure make it take up both comfort and safety, construction elevator is usually used with Tower Crane on the construction site, the average load in 1-3 tons, running speed is 1 to 60 m/min.
