THE PRICE After questioning the according to the users who used JCB 132 D the machine has lone age and small different in performance and it works perfectly even if it faced obstacles. Also it has a high speed in finish work, the compacting gives high efficiency during bad weather. on the other side, the CAT need for preservation more than the competitors, according to one of the customers, the cat CS533E and CS54 has so less age comparing to the power that can do. one major problem is that the machine can’t work under high pressure. OBSERVATION OBSERVATION Among the mentioned three loaders: JCB 456 ZX, JCB 436ZX and CAT 966H, the most suitable selection for given construction project is JCB 456 ZX comparing to others as it offers more engine power (160Kw (214hp)), bigger capacity i.e. of 3.5 m3, and higher speed (37.4km/h) than others. Moreover, it has lower secondhand and renting prices comparing to other loaders with same specifications. Considering the popularity of JCB company in Oman, the accessibility of finding spare parts is very high, especially not from the main company. As the site comprises of large heavy rocks, renting 3 loaders will be the most apposite choice as it will help in completing the construction work within the specified time period. Usually for large projects companies prefer to buy the most frequently used machines as renting cost surpasses the original worth of the machine and moreover for upcoming projects they can be very useful. As the duration of the project was 24 months, economically buying the cranes seems to be a better option economically. Comparing the prices for both cranes, LEIBHERR 112 EC-H8 costed 24,000 OMR whilst JARLWAY JT145H8 was 4,000 cheaper and was of 20,000 OMR. The costs of the two cranes are so close to each other, which reduce priority to bring one company. According to the operators of both excavators, the JCB JC220 from inside the cabin has excellent view with large windshield which helps to see the hard-wired reversing camera and the factory-fitted, also reduces the noise levels to 72dB inside the cabin when its 103dB outside. Moreover, the operators have experienced that it has less fuel consumption than the old models and the engine gives high efficiency at low rpm at 1500-1600. The only disadvantage was the leakage of oil and slight late response comparing to others. For Volvo EC220, the oil filters are the main problem as they get damage before time and needs to change quicker, also if the oil filters are not changed on time the system will automaticlly turn down the engine. On the other hand, the customers are really impressed with the power of the engine as it more stronger and long lasting than the others. [11] [12] THE FACTORS OBSERVATION 1. JCB 456 ZX The model JCB JS220 CAT 320D L VOLVO EC220 New 60,000 58,000 61,000 Secondhand • JCB Co.: 43,500 • CAT Co.: 54,200 • Volvo Co.: 40,000 • Galfar: 22,000 • Galfar Co.: 33,000 • CCC Co.: 29,000 • CCC Co.: 32,000 • CCC Co. 24,000 Renting 9 /h. 12/h. 10 /h. 2. CAT CS54 THE FACTORS 2. JCB 436 ZX In any construction company it’s required to find the most and the best appropriate required for the construction such as excavators, loaders, trucks compacting machines and cranes. According to the site, the rocky soil will need a specific type of machines which will complete the building in around 24 months of work, it can be increased effected by the weather condition. In this project the information about the equipment will be gathers by visiting a well-knowns companies as Caterpillar, JCB, Volvo, MAN and Hino. And chosen what is the best to complete the building fastest as possible with best price and excellent machines. Supported with figures, tables and discussions After going through all the specifications of the cranes and keeping in mind every required factor related to the construction such as: quantity of the material to be moved, time availability, different sort of usages and work efficiency LEIBHERR 112 EC-H8 was given the preference as it has more powered engine comparing to JARLWAY JT145H8 plus the average lifting speed of former one is 100meter/min which is comparatively more than that of latter one 70meter/min. However, LIEBHERR model is 4,000 OMR more expensive than JARLWAY but this amount can be neglected as LIEBHERR offers more specifications than JARLWAY 1. Max load/capacity 2. Jib Length 3.
