    • Disclosed is a pit cover and method of installing the same. The pit cover includes a plate having a hole defining an area. A block having a threaded hole may be affixed to a bottom surface of the plate such that the threaded hole aligns with the area. A support is associated with the foundation and a groove is defined by one of the pit cover or the support. A protrusion is defined by the other one of the pit cover or the support. The groove narrows from a first width towards a second width. The first width is disposed relative to the second width such that insertion of the protrusion into the groove causes an end of the protrusion to pass the first width prior to passing the second width. The protrusion interacts with the groove to align the pit cover at a predetermined position relative to the foundation.
    • 公开了一种坑盖及其安装方法。 坑盖包括具有限定区域的孔的板。 具有螺纹孔的块可以固定到板的底表面,使得螺纹孔与该区域对准。 支撑件与基座相关联,凹槽由凹坑盖或支撑件中的一个限定。 突起由凹坑盖或支撑体中的另一个限定。 槽从第一宽度朝向第二宽度变窄。 所述第一宽度相对于所述第二宽度布置,使得所述突起到所述槽中的插入使所述突起的一端在通过所述第二宽度之前通过所述第一宽度。 突起与凹槽相互作用以将凹坑盖相对于基座定位在预定位置。

    • A lifting apparatus having two rails spaced apart at a distance and two lifting mechanisms, each lifting mechanism supporting one of the two rails. A platform is disposed between the two rails such that movement of the lifting mechanisms causes the rails to displace relative to the platform. A base has the two lifting mechanisms connected thereto and the platform is connected to the base. The base moves horizontally along a floor. Further, the floor may be disposed in a pit and the travel of the rails between minimum and maximum rail heights may be greater than 62.5% of the depth of the pit. The minimum rail height may be less than 50% of the depth of the pit.
    • 具有间隔开的两个轨道和两个提升机构的提升装置,每个提升机构支撑两个轨道之一。 平台设置在两个轨道之间,使得提升机构的移动导致轨​​道相对于平台移位。 基座具有与其连接的两个提升机构,并且平台连接到基座。 底座沿地板水平移动。 此外,地板可以设置在坑中,并且轨道在最小和最大轨道高度之间的行程可以大于坑的深度的62.5%。 最小轨道高度可能小于坑深度的50%。
