How to choose heavy duty medical casters with locks

What are the regular size options for medical casters?

The regular size options for medical casters are 3 inch casters,4 inch casters,5 inch casters. 

3 inch medical casters equal to 75mm, 4 inch medical casters equal to 100mm, 5 inch medical casters equal to 125mm

Different size of medical casters corresponds to the different load-bearing

Europeans，Americans and Asians have different body composition, so the bone density is not the same. Europeans and Americans have a much larger bone density than Asians. Generally, European and American adults are heavier than Asians

One of the necessary conditions for choosing medical casters with locks

One of the necessary conditions for choosing medical casters is to bring brakes，people always call another way medical casters with locks.

Medical casters generally have regular wheels and central control wheels. The regular wheels have an external brake pedal, which can be braked by stepping on them. If the central control wheel is linked by a brake device, the brake pedal is stepped on at the end of the bed It can brake 4 wheels at the same time to achieve the effect of fixing the bed.

What is a medical casters with locks? What exactly does the medical casters with locks do? What kind of medical casters with locks are there? Is the quality of medical casters with locks good? With this series of questions, today the caster wheels brand iTQfurniture will take everyone to know about the medical casters with locks. When the caster is in a static state, the object of work needs to be positioned, and the auxiliary locking component installed for the caster is the brake of the caster. medical casters with locks are called brake casters. This kind of brake caster is what we call medical casters with locks.

So what exactly does the medical casters with locks do? The role of the medical casters with locks refers to the auxiliary component installed in order to lock the caster,when the caster is in a static state. It is worth noting that the brakes of casters generally work in a working environment with no slope. Special requirements for the design of caster brakes, please consult the manufacturer.

According to different working environment requirements, the classification of brake casters is also different, and the brake design of the casters is also different. iTQfurniture Changsha Tianqi Furniture Co., Ltd. has designed, developed and mass-produced about a variety of medical casters with locks according to customer requirements, including directional brake casters, universal brake casters, full brake casters, rotation direction brake casters and smart brakes Casters, etc., are widely used in industry, agriculture, scientific research sites, national defense and household applications.

How to choose the material of medical casters?

First of all, we must consider the use environment. The use environment of general medical equipment is not as harsh as the industry, because the hospital itself has certain requirements for temperature, humidity, cleanliness, etc. But once it is expected to be used, it must work in a special environment, such as high temperature and high humidity, or low temperature. The three conditions are combined: pressure, silence (using rubber PU material to achieve a silent effect), and wear resistance.

With the application of TPR in the medical field, it can not only be applied to the infusion tube, but also can be applied to the casters. The hospital needs a relatively quiet environment. If the hard material casters are used, they will emit a lot of echo when rolling. Sound, but if you use TPR caster material, you can reduce the noise when rolling and create a more comfortable environment. Today, I will introduce to you how to choose TPR caster material.

One: load-bearing capacity.

    The load-bearing capacity of tpr materials is generally not very high. At present, the maximum load-bearing capacity of TPR as an outsourcing rubber in the market is 300kg. Because the TPE material itself is relatively soft and rigid, and is formed by bonding with the frame, it will generate a lot of heat when the load moves and accelerate the deformation of the material, which will cause the caster frame and rubber to fall off or crack. The weight of the caster material can be up to 300kg.

Two: The material selection method of different frame materials is different.

    The skeleton of the caster is generally PP, reinforced PP, nylon, etc. Generally, the caster with relatively low load-bearing capacity uses PP as the skeleton, and some low-end materials even use the recycled PP as the skeleton. It is degradation, so the bonding performance of TPR is higher. If it is reinforced PP, it is generally reinforced by adding glass fiber, so the bonding performance of the material is also higher. Ordinary original package PP generally chooses homo polymer type.

Three: wear resistance.

    Ordinary TPR material, because of its own anti-slip properties, will have worse wear resistance than other materials. However, as the load-bearing requirements of TPR materials for medical casters increase, TPR medical caster materials will be added with appropriate slip agents to improve the surface smoothness. Slippery, reducing the surface friction coefficient of the material, thereby reducing frictional heat generation and increasing friction loss.

    Four: What is the advantage of TPR?

TPR medical casters advantages are Durable, with the characteristics of impact resistance, noise reduction, silence, no damage to the floor, wear resistance, low temperature resistance, fire resistance and puncture resistance.

In summary, how to choose a suitable medical caster, first of all, we must consider the dimension,the large medical caster dimension fit for heavy duty medical casters,the small medical caster dimension fit for light weight medical casters,and then we must choose the medical casters with locks, why is it necessary to have medical casters with locks? Because of medical safety considerations, caster suppliers who do not consider safety factors are not good suppliers. Finally, we have to consider the needs of the hospital’s quiet environment and choose rubber PU, TPR and soft rubber PU quiet caster materials. This is how to choose medical casters.
