Product catalog summary

General Overview: This document outlines the specifications and configurations for the IHI Construction Machinery Limited's Fully Hydraulic Crawler Crane, which has a lifting capacity of 90 metric tons. It covers dimensions, performance metrics, and available equipment options.

Specifications: The crane is equipped with a Cummins QSB6.7 diesel engine, meeting US EPA Tier III and EU Stage IIIA standards. It has a displacement of 6.7 L and a power output of 179 kW at 2,000 rpm. The fuel tank holds 400 L, and the electrical system uses a 2 × 12 V × 120 Ah battery setup.

Performance: The crane features a swing speed of 2.4 rpm, travel speeds of 1.5 km/h (high) and 1.0 km/h (low), and a gradeability of 30% (16.7°). It can lift up to 90 metric tons at a 4.0 m radius, with a maximum boom length of 61 m and an extended length of 71 m with a jib.

Load Hoist System: The system includes axial piston type hydraulic motors and two-stage planetary gear reduction for the main and auxiliary drums, which are grooved with Lebus type grooves. It also features wet type multi-disc clutches and brakes.

Safety and Auxiliary Equipment: Standard safety features include a moment limiter, hook over-winding prevention, boom over-hoisting prevention, and automatic brake systems. Auxiliary features include ultra-low speed control, slewing and winch speed control, and a remote controller for jack and crawler expansion.

Options: Optional features include a free fall function for drums, additional drum devices, a slewing mode selector switch, TV monitors for drum and hook load views, and various lighting and safety enhancements.

Wire Rope and Boom/Jib Combinations: The document specifies the types and lengths of wire ropes for different functions and details the combinations of main boom and jib sections for various operations.

Working Range and Load Charts: Load charts are provided, detailing rated lifting loads for different boom and jib lengths and configurations, along with working radius and boom angles.

Specifications: The document includes detailed specifications for the machine's weights and dimensions. The base machine with crawlers, A-frame, and wire ropes weighs 53,400 kg, with a width of 3,340 mm. The crawler frame weighs 10,100 kg, with a width of 1,100 mm, and the counterweight totals 30,600 kg.

Procedures and Calculations: To calculate the actual load for the main boom, the weight of all lifting devices must be subtracted from the lifting load. Additional weight reductions are necessary when using a jib, and the rated lifting load is limited by the number of part lines used.

Norms and Recommendations: Rated loads are based on operation on a firm, level surface, within 78% of tipping load, and a forward stability factor over 1.15. The working radius is the horizontal distance from the center of rotation to the load's center of gravity.

Attachments and Parts: Various attachments and their dimensions are listed, including the 90-ton hook block and auxiliary jib, along with their weights.

Contact Information: Contact details for IHI Construction Machinery Limited are provided, including their Tokyo address and phone and fax numbers.
