每侧履带的行走机构由一个变量双速柱塞马达、行星减速器和制动器组成，行走制动缓冲阀与马达一体安装，吸收了行车时由于制动或载荷变化带来的液压冲击。

Travel mechanism of each track consists of a variable two-speed piston motor, a planetary reducer and a parking brake, travel brake buffer valve is mounted on motor to reduce hydraulic shock.

再加上威德福独特的高性能缓冲弹簧，柱塞能够承受在地面和井下高强度的冲击。

Coupled with uniquely designed bumper springs from Weatherford, the plunger can withstand high impacts at the surface and downhole.
