1, the device height

The height of the casters means the maximum vertical distance from the casters and wheels. The vertical distance from the ground to the location of the equipment installation.

2, the structure of the caster

Used to make the device move freely under the device. Casters are divided into two main categories: a single wheel mounted on the bracket made.

A fixed casters

Can only move in a straight line Fixed bracket with a single wheel.

B activity casters

Can travel in any direction. 360 degree steering bracket with a single wheel.

3, the stent to the center distance

Refers to the center of the rivet vertical line to the center of the wheel center horizontal distance.

4, the driving load

Casters load-bearing capacity while moving. Also called dynamic load. The dynamic load of casters varies depending on the specifications of the implementation and the test method of the factory. But also because of the different wheel data. The key is whether the structure and quality of the stent can withstand impact and shock.

5, the impact load

When the device is subject to the impact or shock load bearing casters moments bearing capacity.

6, turning radius

Proper spacing allows the caster to make 360-degree turns. Rotational radius of a reasonable or not directly affect the service life of the caster. The horizontal distance from the center line of the rivet to the outer edge of the tire.

7, static load

Static load should be at least 2 times the impact load. Casters can withstand the weight of the static state. Static load in general should be the exercise load (dynamic load) 56 times.

8, driving flexibility

On the smooth surface, the factors that affect the driving flexibility of the caster are as follows: the structure of the scaffold and the selection of stents and steel, the size of the wheel, the wheel type, the bearing and the like. The bigger the wheel, the better the driving flexibility. Hard, narrow wheels are more effortless than flat-rimmed soft wheels. But on the uneven ground, soft wheels save energy. But on uneven ground, soft wheels can better maintain the equipment and shock absorbers.

9, turn

Shorter turning radius will increase the steering difficulty, hard, narrow wheels easier to turn than the soft, wide wheel. The turning radius is an important parameter for wheel rotation. Too big will cause the wheel to shake and shorten the life span.
