3 Hydraulic splitter (without hoses) ⅰ Introduction 3

4 The hydraulic Rock & Concrete splitter is our newly developed Product which is a powerful and extremely cost-effective alternative to other conventional demolition techniques. It functions according to the proven wedge principle where by a strong force is applied in an extremely constricted space. Rock and concrete put up considerable resistance to forces applied externally. By comparison the resistance of rock and concrete to force applied internally is 90% less, with the result that they disintegrate relatively easily. The PD350 hydraulic rock & concrete splitter is the most suitable tool for demolition It has many advantages: small cubage, light, easy to operate, high efficiency etc. Now it is widely used in stone quarry, mineral mining and capital construction. It is also an indispensable tool in clearing the barrier n city construction, river dredging, salvation etc. Splitting cylinder Transport rack pump set not include hoses 4

Make sure the following thing is ok. a the oil volume in the tank meets the required volume b the hydraulic hoses is unblocked. Operation a lubricate the working surface of wedge set with our special lubricant and install the counter wedge onto the wedge. b put the wedge set of splitting cylinder into the hole drilled vertically. c start up the diesel motor on pump unit. c When to split a rock or concrete, steer the lever of the control valve on pump station. Turn the lever to the position Ⅰ(or Ⅱ)as the following fig show. d The steer the control lever of the splitting cylinder, turn the lever to the position Ⅰ (or Ⅱ)the splitting cylinder begin the work of splitting. e After breaking the rock or concrete, turn the lever of splitting cylinder to position Ⅱ(or Ⅰ) the wedge begin to retract. f Unload the oil pressure by turning the control lever to position 0 and began another splitting work. g After finishing splitting work, unloading the oil pressure, turn off the diesel motor. 2#outlet 2#outlet forwarding wedge Ⅰ ⅡO unload position Ⅰ ⅡO unload position 1#outlet 9 1#outlet retract wedge control lever of pump unit control lever of splitting cylinder

10 Connection If multi-splitting cylinder is used, then a distributor must be used for connection between splitting cylinders and pump unit ( as following fig show).

Normally the working pressure is adjusted to be 60MPA, for it would damage the hydraulic oil circuit if it exceeds 70MPA 10

13 Selection of splitting hole point 0.5m 0.5m 0.5m 0.5m 5m It is a necessary work for engineer to select proper splitting position on a rock or concrete. Properly selection of the splitting position will enhance working efficiency. The selection of splitting position should meet the following requirements. Axis of all holes must on the same plane. Proper number of drill hole and proper distance between holes. Minimum drill hole depth is 500mm Secondary splitting Some rock or concrete with high strength are not easily broken first time So we offer enlarging counter wedges with different width ` first counter wedge enlarged counter wedge ⅳ Care and maintenance of the Hydraulic splitter Fill the oil tank with sufficient hydraulic oil if the oil mark shows the oil in not enough for work. 13

14 Select proper hydraulic oil Viscosity and temperature: Minimum viscosity 13cSt Viscosity in case of working temperature 20cSt to 43cSt Minimum ambient temperature -20 Recommended Working temperature 50 to 60 Working temperature range 30 to 70 Maximum permissible working temperature 80 If the machine is not in use, hydraulic hose should be cleaned and keep in cool and dry place to prevent it from wearing. Seals When the machine is at work, pay attention to whether there is oil leakage. See trouble shoot if there is an oil leakage. Seal kits Description Material Measurement Quantity O ring Rubber φ12*1.9 4 O ring Rubber φ25*2.4 1 O ring Rubber φ50*2.5 1 Make sure the surfaces of the wedge sets are sufficiently lubricated. If there is any abrasive damage on the surface, polish it immediately. When the machine is not in used, keep it in a dry and cool place and lubricate the surface of the wedge set. 14

Ensure screw couplings allow Shut-off blocks not open free flow. Open shut-off blocks Control valve blocked Replace Low oil pressure Pumps worm Check pressure and oil flow using measuring kit. Replace pump if necessary Leakage Oil leaks from screw coupling Tighten screw couplings Other oil leakage Replace seals 15
