What is the difference between a double girder crane and an overhead crane?

 The main difference between a double girder crane and an overhead crane is in their design and construction:


1. Girder configuration:

   - Double girder crane: Has two parallel overhead girders that span the length of the crane. This provides more load capacity and stability compared to a single girder.

   - Overhead crane: Can have a single girder or double girders. The defining feature is that the crane bridge travels on overhead rails or runways.


2. Load capacity:

   - Double girder crane: Generally has a higher load capacity than a single girder overhead crane, due to the increased structural strength from the two parallel girders.

   - Overhead crane: Load capacity varies based on the number of girders and the crane's overall design.


3. Application:

   - Double girder crane: Commonly used for heavier loads and in industrial applications like manufacturing, warehousing, and construction.

   - Overhead crane: Can be used for a wide range of loads and applications, from light-duty to heavy-duty, in various industrial settings.


4. Clearance:

   - Double girder crane: The dual girders provide more vertical clearance underneath the crane compared to a single girder overhead crane.

   - Overhead crane: The overall height of the crane system, including the girders and runway, determines the available vertical clearance.


In summary, the key difference is the use of two parallel girders in a double girder crane, which provides increased load capacity and stability compared to a single girder overhead crane design.

What precautions should be taken when disposing of dodecyl sulfate sodium salt?

图片
 When disposing of dodecyl sulfate sodium salt (SDS), it’s important to follow safety and environmental guidelines.  Here are some key precautions to consider: Check Local Regulations : Always refer to local, state, and federal regulations regarding chemical disposal. SDS may be classified as hazardous waste in some areas. Personal Protective Equipment (PPE) : Wear appropriate PPE, including gloves, goggles, and lab coats, to protect against skin and eye contact. Neutralization : If applicable, consider neutralizing the SDS with a suitable reagent before disposal. Consult safety data sheets (SDS) for recommended neutralization procedures. Containment : Use appropriate containers for waste collection. Ensure that the containers are labeled clearly as containing hazardous materials. Avoid Discharge into Drains : Do not dispose of SDS down the drain unless specifically permitted by local regulations. It can be harmful to aquatic life. Waste Disposal Services : I...

How to iron lyocell fabric​？

图片
 Ironing lyocell fabric is a task that needs to be handled with care. The first thing to do is to read the care label to get the right instructions. Get the following items you need: an iron, an ironing board, and a spray bottle filled with water. In case you have any doubt, if you get it from the lyocell fabric suppliers they can always offer you with some beneficial care tips. Setting the Iron Put your clothes and the equipment in front of you and start by choosing the right heat level on the iron (the low or medium one). Don't try to use high temperatures as they can be harmful to the material. Do you have a steam iron? If so, the best way to remove the creases is to activate the steam. So, the water only will do the job very effectively. If you want to achieve perfect results, a slight spritz of water will help to moisten the fabric, and before doing, it rubs out the wrinkles before applying high heat .
