Roots pumps are dry running pumps, ideal for industrial processes in which oil-free compression is required to avoid contamination of the pumped media with operating liquids like oil or water. It can be used to evacuate gases and vapors in the fields of coarse and fine vacuum. Typical applications include semiconductor processing, vacuum distillation, packaging, steel degassing, thin film coating, metallurgy, low-density wind tunnels and space simulation
A rope fitting is ideal for heavy ropes used for securing large ships to single point mooring buoys and the like as a substitute for conventional thimbles. The crown of an eye formed in the rope is fitted with a sheave and both are encapsulated in a suitable material such as urethane plastic thereby forming a plug which can be inserted in a shroud attachable by a cylindrical bore to a shackle by a shackle bolt.
Rope guide is available on 1 to 10 ton monorail hoists. It is to permit side pulling without binding or piling the wire rope on the drum. Their models feature a specially engineered bronze guide block and extra-deep drum groove. The guide block which follows the drum grooves distributes and the rope evenly at two points for better cable control.
Rope Lock is a device used in a counterweight fly system to keep a rope from moving. It consists of two steel claws, which are pushed against each other to keep friction against the rope. A long steel handle engages the lock when vertical and releases it when horizontal. This is designed to only hold in-balance loads. It provides structural support and holds them at a level easily accessible for rail operators.
