1) As important branches of RH series Edge Rounding Machine, RH1500 to RH3000 models machines are for completing on deburring and trimming along edges of large steel plates, with width from above 1,000mm up to 3,000mm:
2) Customer had acceptance on RH3000 model at Wuxi JACK workshop, with a piece of large steel plate: (Fig.1)
1) Function: The steel plates being rounded and trimmed on its four edges can greatly raise moisture resistant capability of coating adhesion, thus benefitting on finished product. This is one of the critical specifications for machineries and utilities operating in humid environment, or surrounded with water and steam: Bridge, Ship, Port Machinery, Offshore Oil Platform...;
2) Correspondingly, the typical applied industries include Shipbuilding/ Port machinery/ T Beam Production/ Steel Structure, etc. In this respect, Edge Rounding Machine is an indispensable equipment at facilities of these industries;
3. Mechanical Structure: With plate width exceeding 1,000mm, mechanical structure of Large Plate Edge Rounding Machine also greatly differs from that of small plates models: From compact open structure for RH800- RH1000 conventional models, to large dimension BOX frame for RH1500- RH3000 models;
4. Operating Scenario: As can be found from large banner of this product page, a piece of carbon steel plate was being sent into Wuxi JACK RH3000 model large Plate Edge Rounding and Trimming Machine, for being trimmed and rounded on its edges;

As can be checked from the above design print, mechanical main frame of Wuxi JACK RH3000 Large Plate Edge Rounding Machine has the overall dimensions of:
1) Width 5,000mm;
2) Total height 2,400mm, and 1,700mm height for its horizontal cross beam;
3) Depth 1,400mm;
a) The entire mechanical main frame is a solid box beam structure, with 4 pieces of upright round or square columns holding up the entire structure of machine main frame;
b) Conveyor: There are 10- 12m length input and output roller tables, at the infeed and outlet of the machine respectively:
1. Applied Industries: RH1500 to RH3000 large model machines are basic and requisite equipment in Industries and Large Scale Projects which work in sea, river, lake… Such as Ship Building, Port Machinery, Sea Cross Bridge Construction, Offshore Drilling Platform, Steel Structure;
2. Work Station: Edge rounding is usually at beginning of production line, 1st operation area, before welding and fabrication operation stations;
3. Other equipment and machines which are often installed and put into use together with large steel plate Edge Rounding and Trimming Machine:
1) XBJ series Edge Milling Machine;
2) J series Stiffener Plate Element Straightening Machine;
3) MP series Plate Butt Joint Welding Machine;
4) DX series Beam End Face Milling Machine;
5) T Beam Production Line, etc.
