Japanese manufacturer Maeda Seisakusho Co. Ltd began its professional activity back in 1962 in the city of Nagano as a subsidiary of the Shinonoi Machinery Factory Corporation.

But just a year later, in 1963, Maeda was able to go her own way of development by entering into a full-fledged cooperation agreement with the oldest Japanese engineering company Komatsu Limited, which specialized in the production of diverse road construction equipment and units for it. This collaboration has continued to this day, and a huge number of Maeda special equipment is equipped with reliable and economical Komatsu engines.

At first, Maeda only dealt with after-sales service for Komatsu products. But already in 1968, the talented and ambitious designers of the company decided to create an innovative lifting mechanism based on a small off-road vehicle chassis. The decision was dictated by the absence of any compact crane installations on the specialized equipment market for autonomous handling of loading and unloading tasks in dense urban areas and rural areas.

 

First Maeda cranes

The first brainchild of Maeda was the MC100 loader crane, which was a pickup truck with a loading platform, complemented by a boom type crane. The special vehicle quickly gained popularity among builders, private entrepreneurs and farmers, but complaints also began about the insufficient carrying capacity of the model. Therefore, in 1971, Maeda launches a new MC150 crane model based on a 2-ton truck.

But even this was not enough for the rapidly developing economy of the country. Just three years later, in 1974, an improved MC200 model appeared on the market, which combined a heavy truck and a telescopic crane installation with a lifting capacity of 1 ton.

 

Outlandish Spider Crane

At the same time, in an economically strong Japan, a construction boom began in the high-rise residential and office sector and related infrastructure. Due to the lack of space, new buildings had to be erected on the site of old low-rise buildings. Standard chassis and direct outrigger systems did not allow efficient use of existing lifting equipment in direct proximity to the operation site, which significantly increased the time and laboriousness of dismantling worn-out buildings, arranging foundations and erecting walls for new buildings.

Maeda Seisakusho Co. Ltd was one of the first to understand this situation and in 1980 offered a completely new type of compact crawler crane. The machine was called the Mini Spider Crane CP150 and differed from all other analogues by a system of four multi-position outriggers. The outriggers had an articulated design and could provide the machine with exceptional stability on any type of surface, including those with difficult terrain.

 

Development of the range of Maeda mini cranes

The success of the spider crane was overwhelming. In addition to the fact that the CP150 seamlessly occupied a working position close to the object and functioned with amazing accuracy, it also perfectly coped with high-altitude work indoors and on floors, thereby taking on the lion's share of manual labor and many manipulations that previously required application tower crane. Thanks to the Mini Spider Crane CP150, construction costs have been reduced.

The technical novelty did not pass by numerous companies engaged in maritime transport. Maeda received a special order for the development of universal self-propelled mini-cranes for work in the conditions of the port, ship deck and holds. 1987-88 the company creates a range of Marine Crane MC264AM/364AM.

Invaluable experience in the use of lifting mechanisms in difficult sea conditions and cramped spaces allowed the designers to perfect the system of spider outriggers. Also, the stability of the machine was increased due to the low center of gravity and innovative hybrid drives were created that solve the problem of harmful emissions when working in a confined space.

All these developments were embodied in the Spider Crane MC264HC, which was released in 1989. Just a year later, the first mini-crane with remote control Spider Crane MC354C (Radio Controller) appeared, which further increased the versatility of spider technology and its ease of use.
