Kato KR10H-L2 (MR100Lsp-V)

The Kato KR10H-L2, also marketed as the MR100Lsp-V, is a highly compact and maneuverable 10-ton class mini rough terrain crane developed for urban environments and confined spaces. It was showcased at the Conet exhibition in July 2001. The crane features a fully hydraulic 6-section boom extending from 5.5 m to 23.5 m, with an additional 2-section jib ranging from 3.3 m to 5.5 m. This jib can be luffed hydraulically from 5° to 45°, offering a maximum lifting height of 30 m when fully extended.

The MR100Lsp-V has a strong and efficient Hino W04C-TV intercooled turbo diesel engine, a 4-cylinder engine with a displacement of 3.839L, delivering 118 kW (160 PS) at 3,000 rpm and 461 Nm of torque at 1,600 rpm. The crane utilizes a 4×2 or 4×4 selectable drive configuration with a 4-speed automatic transmission and hydraulic torque converter. It reaches a maximum travel speed of 49 km/h and a gradeability of 60%.

The crane features a 4,500 mm fully hydraulic H-type outrigger system, with intermediate and minimum spread settings (3,500 mm, 2,500 mm, and 1,640 mm), allowing for operation in tight spaces. Its minimum turning radius is 3.92 m using four-wheel steering, enhancing mobility on narrow job sites.

The KR10H-L2 has a total operating weight of 12,985 kg, with a nearly equal front and rear axle load distribution (6,575 kg front, 6,410 kg rear). It comes equipped with a dual winch system powered by hydraulic motors, providing hoisting speeds up to 112 m/min (main winch, 4th layer) and 104 m/min (auxiliary, 3rd layer). It uses 10 mm wire ropes and can perform smooth and precise load handling with features like an anti-two-block system, boom angle limiter, and automatic brake systems.

The crane integrates the Kato ACS (Automatic Crane Safety) system, which includes load moment indicators, voice warnings, and boom lowering prevention. Additional features such as V-type adjustable seats, an air-conditioned operator’s cab, and AM/FM radio with clock ensure operator comfort.

The KR10H-L2 was also one of the four Kato models involved in a legal dispute with Kobelco over alleged design patent infringement, reflecting its significance and similarity in a highly competitive market segment.

With its compact size, precise controls, and reliable performance, the MR100Lsp-V has become a favored mini rough terrain crane for lifting operations in city centers, industrial facilities, and infrastructure maintenance.
