An additional 17 units are planned for delivery before March 2013.
Al Faris was established in 1992, and served the oil and gas industries in the UAE.
It has expanded to include more than 360 units, with almost 200 all terrain models in its fleet.
The firm opened the new depot in Jubail last year with a fleet of 20 Liebherr mobile cranes transferred from Dubai, and supplemented its fledgling fleet with 11 new models.
In October it announced a second depot in Western Saudi Arabia would also be established.
The Saudi rental fleet currently includes Liebherr 29 cranes in the 50-100t class; 18 in the 100-160t class; 12 in the 200-250t class; and 4 in the 300-500t class.
Al Faris said that in its Saudi Arabian market, the 95t class Liebherr LTM 1095-5.1, 5-axle model with a 58m boom offering the largest telescopic boom in its class, is popular for most erection applications.
Technical director for Al Faris, Brian Green, said the decision to grow in Saudi Arabia was made despite challenging working conditions.
"Saudi Arabia is a large market, but it does have considerable drawbacks due to slow governmental procedures and lack of infrastructure," he said.
"There is, however, plenty of work, and we are continuously striving to cope with the demand from the regular customers and hence, the new orders."
The Saudi Arabian market is becoming saturated with lifting equipment, however new upcoming projects are cropping up in remote locations, Al Faris said.
"Mobilization of equipment to such areas is becoming increasingly difficult due to Saudi laws and infrastructure limitations," said Green.
"It’s very different to the boom in Dubai where cranes were in demand by the construction sector and short contracts, virtually as ‘taxi’ cranes, in and out, often completing 2-3 jobs a day."
Dubai continues to be the company’s ‘hub’ for new cranes. "Everything continues to be controlled through Dubai including spare parts," Green said.
