Title:
CIRCULAR CONSTRUCTION MACHINE
Document Type and Number:
Japanese Patent JP3523018
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent breakage of a radiator even in the case when a roof support member is deformed as well as to support the radiator by the roof support member.
SOLUTION: This construction machine is provided with a fragile bracket 21 between a right front leg body 19 of a canopy support member 16 and a radiator 9, and the fragile bracket 21 is formed fragile so as to constantly support the radiator 9 against the canopy support member 16, to deform or to be broken when large external force works. Consequently, it is possible to prevent oscillation of the radiator 9 by supporting the radiator 9 by the fragile bracket 21 at the normal time of travelling and working. In the meantime, it is possible to prevent breakage of the radiator 9 by deforming or breaking the fragile bracket 21 in the case when large external force works on a canopy 25 due to contact with an obstruction and overturning and the canopy support member 16 is deformed.
