A further evolved 4.9 ton capacity crawler crane with the priority on utility on the jobsite. The KOBELCO 4.9 ton capacity CK series were developed to offer mini telescopic boom crawler cranes equipped with practical capacities and features, not just higher specifications. For city sites where working space is greatly restricted, such as road and rail infrastructure under ground, trenches for utilities, foundation work for new buildings, or work on elevated bridges or rail tracks, this high-performance crawler crane series can be relied upon to get the job done. The modified environmentally-friendly engine complies with the latest emission standards and has been improved in basic performance. As urban projects grow in number, great things can be expected of these mini CK90UR and CK120UR. ■ Working ranges & rated load curves ■ Rated Load (Unit: kg) Boom length Upper figs for CK90UR; lower figs for CK120UR Loads: 4 parts of line (hook) Ckl Mini Telescopic Boom Crawler Crane CK90UR/CK120UR A real difference in quietness, in reliability and in easy maintenance! Installed with KOBELCO's unique engine cooling system "iNDr" Already widely used in our mini and mid-sized short tail swing excavators and ultra-short swing excavators, KOBELCO's iNDr system has won fans across the whole spectrum. In this unique design, air-flow to the engine, from inlet to outlet, is kept to a single duct within which the engine and cooling equipment are sited. It represents a major advance not only in cooling performance but also in reducing noise and simplifying maintenance. Units are SI units. { } indicates conventional units. Data with MT crawler pads. Notes ^ Working radius is horizontal distance from the crane's swing center to the center of gravity of suspended load. Dl Ratings according to Japanese construction codes for mobile cranes. [3 Rated loads include the weight of the hook block, sling wire rope, and other tackle. ^ Even with rated loads, the operator is responsible for making appropriate judgments to reduce load or working speed in accordance with wind strength, state of ground, working speed or other condition that may be thought detrimental to safe operations. [3 Empty spaces on the chart mean that crane operation is not possible. [3 For actual loads that can be lifted, weight of the hook, slings etc. must be subtracted from the rated load. Hook weight 60 kg (for both 4.9 t lifting/4 parts of line, and 2.45 t lifting/2 parts of line); 25 kg (1.4 t lifting/1 part of line) ^ Lifted loads during travel are loads lifted while crane is stationary, before travel on firm and level ground. In this case, the load must be kept close to the ground to prevent swaying, and sudden starts and stops, sharp turns etc. should be avoided. [3 Before travelling with suspended load, switch moment limiter to travel with load. [3 While traveling with suspended load, stop other crane operations such as load lifting or lowering, boom raising, extension/contraction, swing etc. noi Speed when travelling with suspended load must not exceed 1.4 km/h (low speed) Note: This catalog may contain attachments and optional equipment that are not available in your area.
