Hammer on the car KrAZ-258 consists of a fixed frame and carriage frame with a swivel, which is placed hammer mechanism and hydraulic. Impact of the - forging weighing 2000 kg, movable hydraulic cylinder. Hydraulic accumulators, and hydraulic shock absorbers features. Output breaker - 250 m2 / h, the impact energy - 10-20 kJ, the rate per minute, respectively, within the range 180-100; weight - 22 tons
When replacing the curbs repaired sections of city streets and driveways used attachment equipment ED-ZM, the excavator to the E-153 "Belarus", which consists of a metal "teeth", tick capture and bucket. This equipment allows you to extract stone from the board of his foundation, load them into the body of the vehicle, to prepare a place for laying a new stone. "Tooth" - a sharp hand with the working arm having a box section, welded from sheet steel of 8 mm. In order to strengthen the sides of welded steel cheeks (10 mm). Go to the sharp part of the "teeth" are welded two "fang", whose surface is covered with wear-resistant material. "Tooth" hydraulic cylinder rotates, attached to the excavator boom with your finger. Steep rocks laid out the capture, consisting of two arms - the mobile and immobile. Bucket capacity of 0.07 m3
of 5 mm thick steel reinforced front and rear plates 10 mm thick. It is intended for the construction of the trench under the stone board.
Performance Machine ED-ZM when removing curbs - 60-65 m / h, the mass of the working equipment - 272 kg.
We recommend to look
- The drive compressor
The drive is made from the compressor PTO engine GAZ-53A through the gearbox, driveline and transmission belt. On the gear drive compressors mounted gear pump NSh-10E, which serves the work of hydraulic machines. In the working position hopper hydraulic cylinder rises thermos, allowing automatic translation of the bucket truck-mounted on the rear bodywork and manual vibratory rollers of the transport to working position. Bucket-truck [...] - Management of special equipment
All management of special equipment is located in the driver's cab. The torque from the motor base unit is transmitted through the PTO, protective sleeve, hand-outs and conical gears on the drive shaft and the shaft conveyor screw feeder, as well as to drive the main brush. The second (upper) power takeoff shaft is used to drive the oil pump gear. Hydraulic drive car is [...] - Power transmission spreader
Power transmission drives the spreader conveyor drive and tipping the spreading equipment. Its main elements - the PTO, drive shaft, gear drives the conveyor, conveyor chain, hydraulic drive. The torque from the transmission base car passed the lower power takeoff shaft to the pump drive the spreading disk, and the top (through the drive shaft) - on the pump drive belt. [...] - Remixer
Remixer - is, in fact, the car "Repaver", equipped with additional dosing and mixing units. Warmed up the old asphalt coating loosen knives, and then screw valve and located behind the blade is fed into the mixing unit equipped with two shafts. Fresh mix from the hopper conveyor enters the dosing unit, which sends it to the mixer, where the old and the new mass [...] - Bunker thermos
Hopper provides storage thermos of hot asphalt mix. The mixture is fed into the truck through the open (with cylinder) hopper bin, after which the mixture is transported to the site of work. The torque from the surface of the power takeoff shaft, flanged to the gearbox base unit is transmitted to the input shaft of the hydraulic pump, and from the bottom of the shaft - the input shaft of the generator [...]
