(EN) Boom of bucket type excavator and producing method thereof
Abrégé
(EN) A lightweight boom of bucket excavators, manufactured by assembling a boom body (23) from a hollow front member (20) having a triangular cross section, an intermediate member (22) and a rear member (21), joining an arm connection bracket (24) to the front member (20), and joining a vehicle body mounting bracket (25) to the rear member (21). Since the boom body (23) is resistant to deformation in cross section, the boom body (23) is reduced in wall thickness and increased in rigidity without the addition of any cross section restraint member. Accordingly the boom can be made lightweight without causing cross section deformation.
