Maeda LC383

The Maeda LC383 is a versatile and compact mini crawler crane built to deliver precise lifting solutions in tight and limited-access environments. With a maximum lifting capacity of 2.93 tonnes at 1.5 meters radius, it is engineered for confined construction sites, urban renovations, and indoor lifting tasks where larger cranes cannot operate.

The crane is equipped with a fully automatic 4-section telescopic boom, extending from 3.18 meters to 8.71 meters, and provides a maximum lifting height of 9.3 meters, while the maximum working radius is 8.38 meters with a 200 kg load. The boom can elevate from 0° to 80° in 12.2 seconds, ensuring quick lifting readiness. Boom telescoping is efficient with a telescoping speed of 5.53 m extension in just 14.3 seconds.

For hoisting operations, the LC383 delivers excellent performance with a hook speed of up to 20.8 meters per minute (at 4 falls, 4th layer), and a single-line speed of 83.2 m/min, supported by a IWRC 6xWS (26), Ø8 mm hoist rope with a length of 73 meters.

Powered by a Yanmar 3TNV88, a 4-cylinder diesel engine rated at 21.5 kW at 2,400 rpm, the crane is capable of long work sessions with a 42-liter diesel tank. The engine offers electric starting, ensuring reliability in various weather conditions.

The drive system utilizes hydraulic piston motors with automatic braking, planetary reduction gears, and steel crawler tracks. It features independent steering controls, enabling enhanced mobility on difficult terrains. The LC383 travels at 2.9 km/h in low gear and 5.0 km/h in high gear, with a 20° gradeability, making it highly adaptable to jobsite conditions. Its ground pressure is a low 0.44 kgf/cm², ideal for sensitive flooring or landscaped areas.

Dimensions of the crane are 4020 mm (L) × 1740 mm (W) × 2495 mm (H), with a total weight of 4,400 kg and a hook block weight of 30 kg.

The slew system provides 360° continuous rotation at a slewing speed of 2.6 rpm, allowing full operational flexibility without repositioning the crane.

The Maeda LC383 includes a comprehensive suite of safety features, such as:

• Overwind protection
• Hydraulic safety valve
• Moment limiter and EMO switch
• Programmable safe load indicator
• Data logger, tilt alarm, and travel lock lever
• Blade with interlock system
• 4-fall and 2-fall hook blocks

Optional equipment includes a single fall hook, 500 kg searcher hook, rubber pads (90 kg), and a large single fall hook, enhancing the crane’s adaptability to varied lifting applications.

In summary, the Maeda LC383 is a compact, high-performance mini crawler crane purpose-built for confined and sensitive work areas. With its advanced hydraulic systems, efficient hoisting speed, and comprehensive safety features, it serves as a reliable lifting solution in both construction and industrial environments.
