Defining the straight arm truck crane is also called the straight arm truck crane truck. It means that the jib of the car is the following part, which is transversely between the car cab and the car. The boom is placed vertically above the carriage. [1]
How it works The straight arm crane with straight arm crane is installed between the cab and the carriage. When the vehicle is in operation, power is taken from the gearbox of the cab to drive the hydraulic pump to rotate. Like a component to provide high-pressure oil, in order to achieve a straight arm crane on the crane to do a variety of azimuth movement.
Car Lift Maintenance 1. The chassis is maintained at the local service station according to the after-sales service manual. According to the manufacturer's product use and maintenance manual provided by the manufacturer, it is essential information for the crane operator to operate the equipment. Before operating the machine, be sure to read the instructions for use and maintenance of the truck crane and operate and maintain it according to the instructions. 2. Keep the truck crane clean for a long time and adjust and loosen the loose parts in time to prevent the parts from wearing out or causing the parts to be lost due to the looseness. 3. Pay attention to the working load of the crane during the running-in period. During the running-in period, the working load should not exceed 80% of the rated working load. It is also necessary to arrange suitable workload for the truck crane to prevent the machine from overheating for a long time. 4. The operator should pay attention to checking the coolant, lubricating oil, brake fluid, hydraulic oil, and fuel oil (water) level and quality frequently, and pay attention to checking the sealability of the vehicle. At the same time, the lubrication of each lubrication point of the truck crane should be strengthened. It is recommended that grease be added to each lubrication point (except special requirements) in each shift. 5. Pay attention to the observation of the instructions of the cranes on the truck. If any abnormality occurs, stop the operation and remove them. Before the fault is found and removed, stop the operation. 6. After the running-in period of the on-vehicle crane is over, the vehicle shall be subjected to compulsory maintenance, and the inspection and adjustment of the crane shall be done well, and the replacement of the oil shall be paid attention to at the same time. The requirements for the use and maintenance of newly purchased lorry cranes during the run-in period can be summarized as: lightening the load, enhancing lubrication, paying attention to operation, and checking. Operators pay attention to and follow the manufacturer's requirements to maintain and maintain the on-load crane running-in period, which can effectively reduce the impact of the run-in period on the crane's performance and life. Crane failure and solution No. malfunction Cause of failure Method of exclusion 1 Telescopic cylinder shock and telescopic arm crawl Air in the hydraulic system, aging of the seal in the telescopic cylinder Exclude system air, replace cylinder seals, add lubricant 2 The idle speed is still too slow Suction pipe is flattened or air sucked from the suction pipe Change suction tube or tighten suction tube fitting 3 Telescopic arms cannot be scaled in sequence Lack of lubricant, bad slider, problem with telescopic arm adjustment Add oil, change the slider, adjust the telescopic arm valve 4 Crane can't raise rated weight Insufficient power of hydraulic pump or damaged seal, overflow valve setting error Replace hydraulic pump or seal, adjust relief valve pressure 5 Automatic drop after lifting Loss of cylinder seal piston seal, balance valve throttle plug and return spring fatigue damage Replace oil cylinder seal or wash balance valve and replace spring 6 Joint point or rotary ring Lack of lubricant Add lubricant 7 Outrigger cylinders cannot support The bidirectional hydraulic lock is broken, and the piston seal ring of the outrigger cylinder is damaged Clean, replace valve locks, replace seals 8 Cylinder oil leakage, leakage inside leakage Damaged seal Replace all seals 9 Winch brake failure mechanism Friction plate damage, motor damage, low system pressure Replacement pads, motor adjustment pressure
