Product catalog summary

Specifications
The document outlines the specifications of a fully hydraulic crawler crane with a maximum lifting capacity of 50 tons and a maximum boom length of 51 meters. It can accommodate a jib combination of 42 meters plus 15 meters. The crane features a slewing speed of 3.5 rpm and a travel speed of 1.6 km/hr, with a gradeability of 40% (21.8º). It is powered by a Cummins Inc. QSB6.7 engine, delivering 149 kW at 2,100 rpm, and has a fuel tank capacity of 240 liters. The crane is equipped with two 12 V 120 AH batteries.

Performance
The main and auxiliary hoisting/lowering speeds are high at 110/80 m/min and low at 55/40 m/min. The boom hoisting/lowering speed is 60 m/min. The standard counterweight is 17.7 tons, and the total operating weight with a 9-meter boom is approximately 51.4 tons. The average ground bearing pressure is 66 kPa.

Load Hoist System
The crane features main and auxiliary hoist drums that are 2-grooved cylindrical drums on individual shafts with a lebus type groove. The boom hoist drum is a grooved cylindrical single drum on a shaft with a lebus type groove.

Standard Equipment
Standard equipment includes a 17.7-ton counterweight and a counterweight removal system. It also features an engine tachometer, diagnostics, hydraulic pressure gauge, fuel gauge, operator’s room lamp, air conditioner, reclining operator’s seat, and safety features such as a swing flashing light, travel warning buzzer, and swing warning buzzer.

Options
Optional equipment includes a tagline, drum rotation indicator, fire extinguisher, combustion type heater, additional lighting and instruments like a yellow rotary light and boom point clearance lamp, and attachments such as 3 m, 6 m, 9 m insert boom, and 6 m basic jib and accessories.

Load Charts and Limitations
Rated loads are based on operation on firm, level ground within 78% of the tipping load. The weight of lifting devices must be deducted from lifting loads. Jib and auxiliary jib configurations affect rated lifting loads, and part lines limit lifting loads, with 1 part line up to 6.5 tons and 8 part lines up to 50 tons.

Compliance
The crane is designed and rated in compliance with ANSI Code B30.5-1.7.1.
