    Abstract: A truck has a cab tiltable between full-down and full-tilt positions by means of double-acting hydraulic lift cylinders. The double-acting cylinder and the control system therefor, which includes a manually, electrically or air driven pump and a manually operable selector valve, enables the cab to be positively moved from full-down to overcenter position whereupon the cab then slowly descends under the force of gravity to fulltilt position. Furthermore, it enables the cab to be positively moved from full-tilt position to overcenter position whereupon the cab then slowly descends under the force of gravity to fulldown position. Each cylinder is provided with two integrally mounted velocity fuses as a safety feature. In the event of a hydraulic system failure, one fuse prevents free-fall movement of the cab when the cab is in any position between full-down and overcenter position. In one embodiment of the invention, both fuses are located in the lower end of the cylinder. In another embodiment, the fuses are located at opposite ends of the cylinder.

    Abstract translation: 一辆卡车通过双作用液压提升缸在全方位和全倾斜位置之间具有可倾斜的驾驶室。 双作用气缸及其控制系统，其包括手动，电动或空气驱动的泵和可手动操作的选择阀，使得驾驶室能够从完全向下移动到超中心位置，于是驾驶室然后在 重力向全倾斜位置。 此外，它使得驾驶室能够从全倾斜位置正向移动到超中心位置，于是驾驶室在重力作用下缓慢下降到完全向下的位置。 每个气缸设有两个整体安装的速度保险丝作为安全特征。 在液压系统发生故障的情况下，当驾驶室处于完全向下和超过中心位置之间的任何位置时，一个保险丝可防止驾驶室自由下落。 在本发明的一个实施例中，两个熔断器位于气缸的下端。 在另一个实施例中，保险丝位于气缸的相对端。

    Abstract: TITLE: LATCHING MECHANISM: A latching mechanism for a cab which is tiltably mounted to the chassis of a vehicle. The cab is normally disposed over the engine of the vehicle in a first or lowered position and is pivotally attached to the chassis at its forward end for movement through 90.degree. to a second or raised position. The latching mechanism securely locks the cab in the lowered position and includes interengaing latching elements attached to the underside of the cab and to the chassis of the vehicle. The receiving means includes a ball detent arrangement actuated by means of a hydraulically powered cam sleeve. The ball detents move radially between a first or unlocked position and a second and locked position. When in the locked position, the detents engage shoulder portions on one latching element to securely lock the cab to the chassis.
