Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and more specifically, it relates to a shock-absorbing and buffering base for engineering machinery seats. Background Technology

[0002] The seat of construction machinery is an important component of the construction machinery cab. During daily operation, mechanical vibrations cause the entire construction machinery cab, including the seat, to shake, affecting the normal work of the operators. Therefore, a shock-absorbing base is needed to install the seat.

In addition, the device only uses springs to achieve shock absorption, and the shock absorption effect needs to be improved. Furthermore, the overall support height of the device is limited and lacks a suitable height adjustment mechanism. Utility Model Content
