Hydraulic mobile truck crane is a kind of lifting and handling machinery widely used in ports, workshops, electric power, construction sites and other places. The name of the crane is the uniform title for lifting appliances. The main cranes are usually car cranes, crawler cranes and tire hangers. The usefulness of cranes is lifting equipment, emergency rescue, lifting, machinery, and rescue.
Advantage of truck crane:1. Boom: 70 Mn plate is used as the big arm, 70 Mn has high toughness, low alloy, increased arm strength, and reduced its own weight.
2. Motor: The selected copper-clad motor for construction machinery has strong heat dissipation and stable performance without brooms, which can meet the power required by the crane. The low power of aluminum-clad motors and the rapid rise in heat are likely to result in boring boring, and there are many new motors.
3. Cylinder: Depends on the material. Thick, chrome-plated, wear-resistant sleeve on the eye of the pin. The accuracy of chrome plating directly affects its quality.
4. Hydraulic oil: no heat, quick start, saving time and labor, high efficiency, life expectancy up to 3-5 years without oil
change, is more than 2 times the ordinary mechanical oil. And do not destroy the parts, we use the hydraulic oil are all 68 # heat-resistant and wear-resistant hydraulic oil, in the trial process through the pressure test and lifting test repeatedly repeated flushing all the impurities in the hydraulic system washed clean and then replaced, so that Hydraulic system cleaner.
