The company has high precision CNC lathe, CNC machining center, grinder, milling machine, lathe and other various types of large-scale processing equipment, 60T tensile testing machine, magnetic powder flaw detector, ultrasonic flaw detector, hardness tester and other testing equipment. The company has more than 30 employees, of whom more than 30% employees with college degree or above, 45% employees are senior technical personnel. The staff has high comprehensive quality and strong technical force. Under the technical guidance and training of senior engineers with many years of experience in manufacturing port machinery fittings, a group of young technicians with excellent skills have been developed.
1) Customization: We have a strong R&D team,and we can develop and produce DYT Series Electro-hydraulic Pusher according to the drawings or samples the customers offered.
2) Cost: We have one CNC machining factory.So we can offer the price and products directly.
3) Quality: We have our own testing lab and the most advanced and complete inspection equipment,which can ensure the quality of the DYT Series Electro-hydraulic Pusher.
4) Advantage: Our engineer all come from ZPMC. So they are very familiar with the port cranes.
5) Capacity: We have a lot of processing equipment, we can meet the needs of different customers with different purchase quantity.
6) Service: We focus on developing high-quality DYT Series Electro-hydraulic Pusher for top-end markets.Our main customers are all the world's leading crane factories and the world's leading ports;
For any new DYT Series Electro-hydraulic Pusher of the customers,we will communicate with customers professionally,listen to the views of customers and give useful suggestions for developing the DYT Series Electro-hydraulic Pusher.

Application:

DYT series Electro-hydraulic pusher is hydraulic drive device which integrates electricity,mechanism and hydraulics.It is widely used as drive and control device for various valves, penstock,pendulum and steering mechanism in metallurgical,building,chemical,port handling machinery and cranes.It is a deal solution for replacing the traditional motor-driven pusher,oil cylinder with hydraulic station and air cylinder with air unit.

Main Design Features:
■The pusher is compact in frame,and easy for installation and maintenance.
■In hydraulic circuit,the two-direction pressure-holding self-lock device is set which can stop and self-lock the pusher at any point in the range of the stroke and keep the outlet force unchangeable.
■In case of emergency (such as power off),the pusher can be auto-locked at this point to avoid accidents.
■All hydraulic devices are set in body without outside connection. Imported famous brand is adopted to seal oil cylinder,which is durable and has excellent sealing effect without leakage or pollution.
■It is simple to control,and easy to realize long-distance control for dangerous area and PLC auto-control by various limit switches.

Note:
1.Base on the parameters of pulling force, pulling speed and stroke during the order of this type, and please look up the relevant parameters of pulling force and pulling speed from the table 3 to the table 5 to assure the order type of the if the selecting type accord to the parameters of pushing force and pushing speed .
2.Please ceil the values of stroke to the recommending ones if the values of stroke are different from these of the recommending values during the selecting types (note : not more then the maximum values of stroke under a certain load ,refer to the table 3 to the table 5) , or please inquire the technical section of the company about these .
3.The invalid load is a prescriptive term of this type , that is to say , not working load , the direction of the load force is the same as the piston rod of electro-hydraulic pusher , if the piston rod of electro-hydraulic pusher is pressed by load , mark “ plus” ; if the piston rod of electro-hydraulic pusher is pulled by load , mark “ minus”
4.The setting angle of pusher is included angle of pusher axis and horizontal when the pusher are working , formulate marking nothing when the hydrocylinder’s axes parallel the horizontal line , otherwise (as shown to the right), marking “plus” or “minus” to distinct them during the order.
5.The window's direction should be convenient for maintaining.The nameplate and the oil level indicator are on the window,and the junction box of motor is against the side of the window.
6.Two limit-switches are equipped when "S" is indicated(original limit and pusher's maximum range limit),which are installed under the pusher. Please indicate in words if any special requirements needed.
