Project: Rotary system of bucket truck

Location: Jiangxi

Project description:

The rotary support of electric shovel in Dexing Copper Mine is a core part of its work. It is very important to overhaul it regularly. Using PLC synchronous control technology, four ultra-high pressure long stroke cylinders with 300T and 2m stroke are used to separate and lift the electric shovel support. The entire process allows real-time monitoring of forces and displacements at each jacking point. Equipped with weighing sensor, accurate measurement of load weight and weight center position. And a hydraulic safety locking valve is installed to ensure that the system can be locked safely at any time when failure occurs at any position. The rotary support of electric forklift truck is separated to achieve the maintenance purpose of overhaul and replacement.

1. Double action, push-pull application;

2. Single point carrying capacity up to 300T, large working stroke 2000mm;

3 can withstand 10% of the lateral force of the bearing capacity of the cylinder, and will not withstand extrusion damage

4. Double acting ultra-high pressure pump station, which can be quickly installed in low pressure and steadily jacking up high pressure;

5.PLC closed-loop synchronous control, while monitoring force and displacement.

Equipment composition:

70Mpa synchronous hydraulic system 1 set

300T long stroke jacking oil cylinder 4 PCS

Cage 4 pieces

4 point synchronous control system 1 set

Project: Maintenance of torpedo tank car of Meishan Iron and Steel Plant

Location: Nanjing Meishan Iron and Steel Works

Project description:

It is necessary to construct 320t torpedo tank car repair facilities for the overhaul project of No.1 and No.3 blast furnaces in Meishan Iron and Steel Company, among which a platform for vehicle maintenance is set up in the separation room of vehicle body.

Torpedo tank car hydraulic frame car machine for the bottom of its walking device needs maintenance, see the torpedo tank car upper part (above the large heart plate) lifted to the appropriate height, convenient for inspection, cleaning, refueling, disassembly and assembly of components, in order to achieve the components integrity, transmission balance, height in place, safe and reliable operation purposes.

Application technology features:

1. The bearing capacity can reach 320T and the working stroke is 300mm.

2. Can withstand 10% of the lateral force of the bearing capacity of the cylinder, without bearing extrusion damage;

3. Double acting ultra-high pressure pump station, which can be quickly in place of low pressure and steadily jacking up high pressure;

4.PLC closed-loop synchronous control, while monitoring force and displacement

5. Hidden design, reasonable use of limited site space, while protecting equipment, avoid accidental damage.

Equipment composition:

70Mpa synchronous hydraulic system 1 set

120T main support cylinder 4 PCS

50T laying aid oil cylinder 4 PCS

8 supporting oil cylinders

Flip oil cylinder 16 pieces

8 point synchronization, flip control system 1 set
