Learn the knowledge of castor, the boss is don't worry I won't choose castor!
A device, highly steering castor height refers to the wheels and steering castor base plate and the largest vertical distance far, far away. From the ground to the vertical distance between the equipment location. Second, the structure of the steering castor for devices under the equipment makes it free to move. Steering castor is divided into two main categories: made from a single wheel is installed on the bracket. A fixed steering castor can only move along A straight line. Fixed bracket with single wheel. B activity to truckle to randomly in any direction. Turning the 360 degrees with a single wheel. Three, support to center distance refers to the vertical line to the center of the wheel core center rivet horizontal distance. Four steering castor, moving load bearing capacity when moving. Also known as dynamic load. Steering caster wheel dynamic load for execution specification and test in a different way and different factories. Also because of the wheel information. The key in the structure of support and quality can impact and shock resistance. Five, the impact load when the equipment has fundamental impact or vibration to castor instantaneous load bearing capacity. Six, the rotation radius of proper spacing of the steering castor can be 360 degrees. Turning radius is reasonable or not directly affects to the service life of castor. Refers to the center of the rivet vertical line to the outside of the tire on the edge of the horizontal distance. Seven, static load, static load should be at least 2 times the impact load. Steering castor can bear the weight of the under stationary state. Static load generally should exercise load ( Dynamic load) 5, and 6 times. Eight, smooth driving flexibility on the ground, the factors affecting driving steering castor flexibility are: stents of the structure and the selection of steel, the size of the wheel, wheel type, bearing, etc. The wheel driving the greater flexibility, the better. Hard, narrow wheel than flat soft wheel. But on the uneven ground, soft wheels. But on the uneven ground, soft wheels can better safeguard equipment and avoid vibration. Nine steering, steering short turning radius will increase the difficulty, hard, narrow wheel more easily than soft, wide wheel steering. Turn the wheel radius is an important parameter. Too much will cause the wheels wobble and shorten the life.
