The Developing History of Rock Block Handler Machine

Date: 2014-10-06      Browse :1390

Block Handler Machine also called as Block Forklift Wheel Loader, which is developed from wheel loader and forklift loader.

 

At beginning, there are 2 types prototype of Rock Block Handler Machine: One is modified by second-hand large-tonnage wheel loader of oversea, take out the bucket and install forks, this kind of machine was widely using at large quarry , but it can only lift 18 tons block, and the max lift height only at 1600mm. The other one is modified by 5 tons rated load wheel loader in China, it was widely using at small quarries, the max. rated load and lift height are 8 tons and 1600mm. These 2 types prototype of Rock Block Handler Machine have 4 types of problem: 1. Rated load is small; 2. It does not have after-sales service; 3. The machine get broken easily; 4. Maintenance cost is high.

 

At the year of 2007, Rock Block Handler Machine is normalized, the XJ953-16 (Rated load: 16 tons) is represent. The price of this kind of machine is about 340,000 RMB, which is acceptable by customers, the machine can lift 16 tons (about 5m³) block over 2200mm height. And has the following functions: leverage, materials handling, stacking, forklifts and so on. This kind of machine is second stage of history of Rock Block Handler Machine. And the theory of Rock Block Handler Machine is maturing.

 

But the XJ953—16 Rock Block Handler Machine only can satisfy the granite mining, the block size and weight should below 5.5m³ and 16tons. This kind of machine can not satisfy the requirement of Marble mining. Then XJ968-18D come out. This machine raise the engine power to 175kw/h, enlarge the fixed shaft type gear box, enhance the tire and machine frame. It can lift 18tons (about 6m³) material over 2200mm height. And has the following functions: leverage, materials handling, stacking, forklifts and so on. The machine price is competitive and has good after-sales service, but it is limited by 23.5 Spec. tire, load of Q axle, and frame.

 

The urgent requirement of user encourages Xiajin Machinery R&D team  to develop the XJ968-25D (25 tons rated load) Rock Block Handler Machine. It is important step of Rock Block Handler Machine developing history. It caused a sensation when showed at Xiamen Stone Fair (2009.03.06), Xiajin Machinery got 40 pieces order in this Fair.

The XJ968-25D has great performance: It can lift 25.2tons (9m³) block material over 3680mm height. One of customer Mr Zhou called us at 15 days after buying our machine, he said this machine is great, you need not have to do any modify for this machine.The XJ968-25D do actually performance well at terrible quarry environment. The frame, transmission, torque convert, tire, cylinder, pilot valve, high pressure pipe do not have problem within 3 years.

 

The improvement and upgrade of Rock Block Handler Machine are encouraged by customers requirement.XJ968-28D(28ton), XJ968-23D(23ton), and XJ968-20D(20ton) are designed accordingly, which fulfill various customers requirement.The XJ968-28D get the honor of Leading Technology in China which issued by government, which further approves Xiajin Rock Block Handler Machine is top-class.

 

So far Rock Block Handler Machine series has following rated loads: 16tons, 18tons, 20tons, 23tons, 25tons, 27tons, 28tons and so on. But when the weight of rock block over 28 tons, the weight of whole machine and 28 tons block is over 60 tons, at this time the traditional designed disc brake can not do good brake, so there are many terrible machine problems around the world, such as machine rollover and slick. Some drivers do not have enough machine safety experience, they stop the machine on the small slope and go to washroom, when they come out, the machine roll into valley.   

The wet type hydraulic axle solves the problems of disc brake. The axle is much safer than the clamp type axle. It can stop car at anytime. The breaking torque force of Xiajin SOMA axle XJ932 is 86000 N/M the axle has 80 tons load. The breaking torque force of Xiajin SOMA axle XJ945 is 96000N/M, it has over 100 tons load. But the breaking torque force of disc brake is 48000 N/M, its rated load is less than 60 tons. The brake With this axle, the machine can stop, start, and move at any time easily even when load more than 40 tons material at slope. The breaking force of Xiajin SOMA axle is double than the disc brake, it greatly solve the problem of brake, brake pad getting heat and so on.

 

  

Xiajin SOMA wet type hydraulic axle is launched in market at the year of 2013. Its outstanding advantages are as following:

1. It will not get heat when work;

2. The breaking torque force 96000N/M, it is double than the disc brake;

3. When the engine powered off, the brake will stop the car automatically;

4. The machine will get brake easily even at slope and parts of wet type hydraulic system have problem.

5. It can get start anytime at slope with full load.

6. Durable and reliable.

These advantages of Xiajin SOMA wet type hydraulic axle bring investors and drivers economy and safety, it is breakthrough technology of Rock Block Handler Machine development.

 

This is second stage of Rock Block Handler Machine developing history.

The XJ976-32D (Rated load: 32tons), XJ976H (Rated load: 32tons with quick couple device), XJ988-40 (Rated load: 40tons), XJ988H  (Rated load: 31tons container loader), XJ998-43 (Rated load: 43tons), and XJ998H (Rated load: 43 tons with quick couple device) are launched in market successively.
