摘要： A trolley is provided for supporting and portably moving an on-car brake lathe. The trolley includes wheels for mobility and a pneumatic cylinder for height adjustment. The pneumatic cylinder includes a piston rod, piston, and air valve. The piston has an equalizing port for dampened movement throughout the cylinder's stroke. The air valve allows static height adjustment of the lathe.
