There has been a "profound" modernization of crane-boring machine BL-205D, which is not only about changing destination parameters, but also in application of modern approaches to product design.
Indicators of use (characteristics) including:• drilling depth increased up to 3 meters;
• load capacity of the crane increased up to half a ton;
• lifting height of the hook increased;
• ability to install a front loader BL-750, carrying capacity of 750-1000 kg.
Design features:
• hydraulic rod rotation with automatic speed regulation and torque is applied;
• in hydraulic system of machine leading manufacturers’ components are used;
• metal base frame is reinforced, as well as crane device, supporting elements and other components through the use of closed profiles, connections "to spike" followed by welding, bending operations instead of using welding and other technical solutions;
• hydraulic winch lifting capacity of 1.25 tonnes is applied
• It is possible to install an additional setting tools and removable ladders
• in hydraulic system of machine high pressure hose of special-purpose are used, which allow to eliminate metal pipes.
