Abstract

PURPOSE:To reduce the width of an outrigger equipment and heighten the stability of a crane at one side thereof, by fitting an intermediate box slidably between the outer and inner boxes of the outrigger equipment to increase the extension of the equipment at one side. CONSTITUTION:An intermediate box 4 is slidably fitted in an outer box 1 secured on the body of a construction machine. Inner boxes 2 are slidably fitted in the right and left ends of the intermediate box 4. Jacks 3, 3 are provided on both the ends of the inner boxes 2. The boxes 1, 2, 4 are provided with stoppers 1a, 2b, 4a, 4b for restricting the sliding of the intermediate and inner boxes 4, 2. A pin 5 for locking up the outer and intermediate boxes 1, 4 on each other and pins 6 for locking up the outer and inner boxes 2 on each other are provided. The pins 5, 6 can be optionally fitted or removed to displace the inner box 2 outward at one or both sides of the machine.
