Concrete pump maintenance in summer

Engineering machinery working in the summer has to withstand the long-lasting jobs and high temperature. High temperatures not only affect the operator's working environment and health, but also do harm to construction machinery engine, cooling system, hydraulic system, circuit and the tires. So it's very important to know how to maintain Concrete Pump to avoid mechanical accident in high temperature. Here are some tips about Concrete Pump maintenance in high temperature. Concrete Pump is a kind of engineering machinery. Trailer concrete pump is a kind of concrete pump.

1. Do a good job in the concrete pumps maintenance in the early stage

In summer, it is better to do a comprehensive maintenance for concrete pump, and replacement engine oil, oil filters, fuel filters, air filters, replacement or adjustment the tape, check the fan, water pumps, generators, is reliable or not, if necessary, carry out maintenance or repair the parts. Increase oil viscosity grade appropriately for high-temperature mechanical working area. At the same time, check whether the cooling system, fuel system is smooth or not. Replace aging wires, plugs, and rubber hose to prevent fuel leakage. Clean the engine body oil pollution, dust to ensure engine excellent in heat radiation.

2. Do special inspection and maintenance on machinery and equipment

The owners of the concrete pump can inspect and maintain some parts by themselves, but for some parts, for example, the circuit, and air conditioning system, it is better to inspect and maintain by equipment manufacturer and professionals to avoid unnecessary loss and dispute. After entering summer, it is no need to do comprehensive maintenance for machinery for one time; you can make a plan for the repair and maintenance based on the usage of the equipment and the daily maintenance work. It must be pay attention to equipment maintenance after entering summer.

3. Engine oil and lubricating oil need to use summer oil, and ensure the amount of oil is suitable. Check if there are frequent oil spills. Supply oil in time.

Long-Arm Excavator, the Fighter of excavators

Different from other excavators, the long-arm excavator adds an extension jib between the machine body and the working arm, which is supported by oil cylinder. And one working jib oil cylinder and one bucket oil cylinder are installed on the long arm, for which one set of oil cylinder operating system is equipped to support the movement of the two oil cylinders. All of these designs double the moving range of the large excavator bucket, which can go higher, deeper and further. The great changes make the long-arm excavator especial for minerals, docks, storage and emergency rescue.

The long-arm excavator has the following advantages:

1.       Need less labor

The high mechanization and simple operation of the long-arm excavator makes higher efficiency and shorter working schedule possible.

2.       High quality

In order to guarantee the reliability of the long-arm excavator in working process, strict quality standard is made to better guarantee the construction quality.

3.       High safety

The distance between the operator and the operating object is long to reduce dangers in the working process.

4.       Strong practicability

The long arm of the excavator can work in the tough place where other excavator can’t reach, and it meets the requirements of various construction sites.

The maintenance of the long-arm excavator

Good maintenance can extend the service life of the long arm and enhance working efficiency, especially in tough environment.

1.       Have the long arm greased at least two times every day. After working in muddy water, wash the machine before adding fuel. Check the joints of the working device to make sure it has enough fuel before starting working. Don’t add new oil until completely pushing the aging oil out by operating the swing arm, rod and bucket for several times.

2.       Wash the machine after working in the shore to remove the salt, and add machine oil if necessary. In cold winter, the piston rod should be put back to the hydraulic cylinder to avoid the clay and water sticking to the piston rod and damage the seal ring of the hydraulic cylinder.

The long-arm excavator should observe the following guidelines:

1.       When making a rotation, the long-arm of the excavator should be 0.5 meters high from the ground.

2.       Forbid knocking the heavy excavator vigorously when the bucket is working, walking and rotating are not allowed either.

3.       The piston rod of hydraulic cylinder should not move to the bottom, safe distance should be reserved.

4.       The long arm should not be overloaded.

5.       Don’t dig directly in the rocky area, crush the rocks before excavating.

6.       The bucket load should match with the specified standards; overload will shorten the life of the long arm and the excavator.
