Gaotang Qilu Hydraulic Machinery—— Your trusted partner!



1. Which machine is best suited for me?
Ask yourself the following questions: How much land space do I have available to produce and store blocks? How many blocks do I want to produce per day? What is my initial budget for a machine? Please be aware that the average block yard that uses one of our machines for the production of blocks, usually have a minimum or 40,000 blocks in stock on any given day.Once you have answered these questions, contact us by email and we will give you the specifications and price for the best suited machine. Please be prepared to give us your answers to the above questions.
2. How do I order a machine from QILU HYDRAULIC?
Once you have decided on the best machine, you will be sent a Proforma Invoice (by email, fax or direct mail). You can then arrange for an electronic transfer payment of a 50% down payment. The desired machine and molds will then be manufactured as per your request. We will then request the balance of payment. Upon receipt of the remaining balance plus shipping charges, the machine will be released to the shipper and forwarded to you. A bill of lading will be faxed or mailed to you (overnight mail).Once the order is placed, the machine is built just for you. If you decide to cancel you order there will be a 20% service charge.
3. How will the equipment be delivered to my premises?
We currently have customers in Central America, South America, Africa and the West Indies. We have a network of freight handlers to deliver machines to these countries.We ship from port to port. We no longer provide door to door service, because we've learned through experience that the customer can secure faster custom clearance and cheaper transportation in their own country. We always look for the least expensive way to ship the machine.
4. In my local market we make several different size blocks and bricks. Can I buy molds to suit?
We have several standard block molds available. We can also make a mold for almost any block, brick or paver that you might see, or design. Simply supply us with the exact dimensions and a sketch or photo of the product, and we will produce a mold to suit it.
5.Do I need a machine for every type of brick or block that I make?
No. All of our machines can be fitted with any mold that was designed for that machine. That includes, paver molds, hollow block molds, solid block molds and all brick molds. So for example, today you can produce 8" blocks and tomorrow you can produce 6" blocks on the same machine by just changing the mold. The following day you can produce bricks. All you will need to do is remove one type of mold and replace it with another. These are quick change molds and the entire process takes about half an hour.
6. What happens if I have a breakdown? 
We use FeDex or DHL International for emergency shipment to anyplace in the world. We are usually able to get spare parts to you within 4 days. However these machines are so well built and robust, that there is seldom a complete breakdown. We suggest regular maintenance of all moving parts. Do not allow concrete to accumulate on moving parts and molds, clean machine daily before closing up for the day. If you have some shapes that are vital to your business, we suggest that you buy a replacement mold, as a backup.
7. What Raw Materials are needed to make blocks?
The raw materials required are cement, sand or fly ash, stone chips and water.
8. What is an acceptable mix ratio?
The ratio of cement, sand and stone chips or gravel in the raw material mix determines the properties of hollow concrete blocks. A ratio of 1:3:6 [cement : sand: stone chips] confers higher strength, while a ratio 1:4:7 can be employed for normal load bearing construction. The water to cement ratio is usually 0.4:1, which is a little less than half the amount of water to cement.
9.Can I get installation?
Yes, only if said arrangements are made prior to receiving your equipment. There are some countries that are politically unstable or present a language barrier for our technicians. Sometimes it is impossible to get a technicians to travel to some countries. If no arrangement is made prior to purchasing the machine and a problem arise during installation, the customer is responsible for air tickets and accommodation of the technician.
