 HYDRAULIC PROPS,
HYDRAULIC and PNEUMATIC CYLINDERS
They are actuating elements of roof support shields, shearer-loaders, drill rigs and other different devices.
1. Hydraulic props for shields supports.
2.General purpose pneumatic and hydraulic cylinders.
1. Hydraulic props for shields supports
Registered designs by OSIM as no.2001 / 0503.
Safety Certificate by INSEMEX Petrosani SECEEx NMATEX 2001 023/22.03.2001.
In this category are included the series 8181, used in all types of shield suports for steam coal mining, using as hydraulic fluid emulsion of oil + water 3 - 5 % at high pressure (<420 MPa).
2.General purpose pneumatic and hydraulic cylinders.
This category include the overall of pneumatic and hydraulic cylinders with internal diameter between 50-250 mm and length of max. 3000 mm.
The manufacturing characteristics can be realised upon the rougliness and anticorosive prescriptions of anysealing element manufacturer.
E.g., Roughness of 0,2-0,4 mm by rolling can be obtained.
The most comounly used anticorosive protection are the zinc and chrome coatings.
