Matters needing attention in refitting the long arm of excavator
Often has the excavator owner to consult: regarding the excavator standard arm how changes into the excavator lengthening arm question, I now share with you several general questions.
1. We should first understand the application field and function of the extended arm of excavator:
The extension arm of excavator has two extension arms and three extension arms of excavator.
The extension arm of two-stage excavator is mainly used for dredging of river course and digging of soil and stone foundation.
The extended arm of three-stage excavator is mainly used in the dismantling of high-rise buildings.
Select the long arm you need to refit according to the working condition.
2. Matters needing attention to when refitting the extension arm of excavator during the warranty period:
In the warranty period of the new excavator refitted excavator extension arm, must coordinate well with the excavator seller quality problem and quality assurance requirements.There are a lot of people in the warranty period before the refit and excavator sales did not coordinate well, in the warranty, the whole machine agent in your excavator warranty on the quality of things or excuses for a variety of reasons, in the after-sales service disputes;In order to avoid future rectifications, the new machine should be modified before the seller of the relevant agreement.The load of the excavator increased after the standard arm of the excavator was refitted with the lengthened arm of the excavator.Of course, in terms of professional design, they are all designed according to the type of excavator, considering and designing the working performance and safety performance of the extension arm of excavator to ensure the quality of the extension arm of excavator.
3. Problems that should be eliminated in refitting the lengthened arm of the old excavator:
The standard arm of the old excavator is refitted with the lengthened arm of the excavator. First, the performance of the excavator should be measured, such as whether the hydraulic output reaches a certain pressure.Can the walking mechanism and rotary plate structure bear the extension arm of the excavator and how long the extension arm?The service life of the old excavator and the length of construction operation have direct influence on the performance of the excavator itself, such as no digging force, weak lifting arm and slow walking.Due to these reasons, it is difficult to give full play to the efficiency of the excavator.Before refitting, it is better to conduct quality inspection on the excavator. Through quality inspection, we can have a clearer understanding of the performance of our excavator, so that we can choose a more suitable extended arm for refitting!
4. Clear working requirements and working environment of the extended arm of excavator.
The length of the extension arm of excavator is directly related to its own quality and output pressure.When we select the extension arm of excavator, we need to adjust the length of the extension arm of excavator according to the working environment, working requirements, own quality, digging bucket and other ancillary equipment capacity.The extension arm of two-stage excavator usually involves three main parameters, namely, digging height, digging depth and working radius.The lengthening arm of the three-stage dismantling machine usually involves three main parameters: lifting height, safe working height and operating radius.Only comprehensive factors can determine the length of the extension arm of the excavator.
5. Reference parameters of lengthened arm configuration length of relevant refit excavators;
The weight of the extension arm of the two-stage excavator and the configuration of the long arm:
The 10-16 ton machine can be equipped with the extension arm of 13m excavator.
The 20-22 ton machine can be equipped with the extension arm of 15.4 meters excavator.
The 20-25 ton machine can be equipped with the extended arm of 18 meters excavator.
26-35 ton machine can be equipped with extended arm of 20 meters excavator.
36-40 ton machine can be equipped with 22-meter long arm of excavator;
The 45-65 ton machine can be equipped with the extension arm of 26m excavator.
The weight of the extended arm and the configuration of the long arm:
12-15 tons of machine weight can be equipped with 12 meters long arm;
The 16-22 ton machine can be equipped with 14 meter extension arm for demolition.
The 23-26 ton machine can be equipped with 16-meter extension arm for demolition.
30 tons of machine weight can be equipped with 18 meters long arm;
The 35-ton machine can be equipped with 20-meter extension arm for demolition.
The 40 ton machine can be equipped with 22 meters long arm for demolition.
The 45 ton machine can be equipped with 24 meter extension arm
The above parameters are for reference only, and the specific configuration requirements can be consulted by professionals: 13925811073.
6. Name and quantity of relevant components of modified excavator extension arm
Make relevant configuration refit according to the requirement of excavator itself, can use the configuration that returns original car, need not change when refit.The following accessories are required to be modified.
A. Add 1 extended arm (the arm is equipped with hydraulic steel pipe and lubricating pipe)
B. Lengthened 1 arm (the arm is equipped with hydraulic steel pipe and lubricating pipe)
C. One standard earthmoving bucket
D. One oil cylinder of bucket
E. One set of connecting rod assembly (H type connecting rod, left and right swinging rod)
F. 3 butter pipes
G. 4 high-pressure hoses
H, 6 pin shafts (1 pin shaft connecting big and small arms, 1 pin shaft connecting oil cylinder of bucket, 1 pin shaft connecting oil cylinder of bucket, 1 pin shaft connecting rocker and forearm, 2 pin shaft connecting bucket
7. Production process of extension arm of excavator
Computer design - CNC cutting (blanking) - machining - bending shape - (automatic and manual welding) welding large boring machine boring -- component installation - -- -- -- -- -- sandblasting processing - grinding of the ash - spraying - inspection -- -- -- -- -- the qualified products packaging factory.
Manufacture time of excavator extension arm: it takes about 17 days to finish the machining of one set of extension arm.
