Illustration of a level spreader designed to infiltrate road drainage. A level spreader is an erosion control device designed to reduce water pollution by mitigating the impact of high-velocity stormwater surface runoff. It is used both on construction sites and for permanent applications such as drainage for roads and highways.
The spreader is placed between the container and the lifting machine. [1] The spreader used for containers has a locking mechanism at each corner that attaches to the four corners of the container. A spreader can be used on a container crane, a straddle carrier and with any other machinery to lift containers. Spreader operation can be manual ...
High- and low-liquid-level controls High- and low liquid-level controls normally are float-operated pilots that actuate a valve on the inlet to the separator, open a bypass around the separator, sound a warning alarm, or perform some other pertinent function to prevent damage that might result from high or low liquid levels in the separator.
Rigging of an asymmetrical scaffolding piece: the lifting beam is blue, the load is attached to the beam using grey slings. The lifting beam (also known as traverse, spreader beam) is a steel beam that is attached to the hook of the crane in order to spread the slings from one end of an elongated load (like a wall panel) to another.
Cell spreaders can be made from glass, plastic, or metal, and come in various shapes. A Drigalski spatula is a cell spreader consisting of a cylindrical rod or wire bent in the shape of a triangle with a handle. [1] [2] [3] Another variant is a rod bent in L-shape. [4] Extrusion molded versions can be T-shaped. [5]

Reduce vat level if discharged solid is in the form of thin and slimy cake or if the discharged solid is very thick. [ 4 ] [ 7 ] [ 8 ] Decrease in the vat level eventually leads to a decrease in the portion of the drum being submerge under the slurry, more surface exposure for the cake dying surface hence, larger cake formation to dry time ratio.
The spreader's function is to prevent the ladder from twisting in the prevailing weather conditions when in use. The lowest four steps of the ladder are normally made from a synthetic or composite resin , which is more resistant than hardwood, to the interaction between the host vessel and the pilot boat coming alongside.
