Hydro Mechanical Equipment

We undertake complete design, drawings, Manufacturing, Supply, Erection and Painting, of Hydro Mechanical Equipments which has following items:

Radial Gate

Radial gate is designed for a wide, clear waterway opening. A radial (or taintor) gate acts similar to a section of a drum. Pressure is transferred from the curved face through the horizontal support beams to the radial arms at the sides of the opening. The arms act as columns and transfer thrust to a common bearing located on either side of the gate opening. Flow is underneath the curved face as the gate is opened. This design results in a lightweight, economical gate that can be opened and closed with minimum effort and with comparatively small number of turns of the hand wheel on the hoist.

Bulkhead Gates/ Vertical Gates

Bulkhead gates/ Vertical gates are large fabricated steel gates placed in vertical guides embedded in a concrete slot. The gates are normally operated with the use of an overhead crane. They can also be raised and locked in place to provide a method of storage. The gates can be designed to stack one on top of the other to close a large opening.

Stoplogs

Stoplogs are hydraulic engineering control elements that are used in floodgates to adjust the water level or flow rate in a river, canal, or reservoir. Stoplogs are sometimes confused with flashboards, as both elements are used in bulkhead or crest gates. Stoplogs are typically long rectangular timber beams or boards that are placed on top of each other and dropped into premade slots inside a weir, gate, or channel. Other materials, including steel and composites, can be used as stoplogs as well. Stoplogs are designed to cut off or stop flow through a conduit.

Penstock

A penstock is used to control the flow or level of a liquid and consists of a sliding door controlled by a mechanically operated spindle, which moves over an aperture in a frame, which in turn is secured onto a structure.

The word 'penstock' originates from the days of water mills when it was not uncommon for a pond (stored or 'penned up' water), which was used to feed the water wheel or mill race to be referred to as the 'pen'. The timber stop logs used to control the flow onto the water wheel was called the 'stock'. Later, as the need to accurately control the velocity of the water wheel became more critical, a single sliding gate operated by a lifting mechanism replaced the stop logs with their individual sections. During the 17th century, the words 'pen' and 'stock' became combined into a single word - PENSTOCK.

Wheeled Gates

Wheeled gates are commonly used within intake structures for isolation and emergency shutoff, or as vertical-lift spillway gates. They are designed to close and open under flow, whereby they are subject to various hydraulic forces such as down pull and catapulting loads. They are of either upstream or downstream seal design, and can be operated by hydraulic, rope or screw hoists.

Rope Drum Hoist

Electrically operated Rope Drum Hoists are used for lifting/operation of Gates. These hoists are consists of wire rope, drums, shafts, coupling, gearing arrangement, motor, electromagnetic brake, gate position indicator, limit switches, control panels, cable and manual operating arrangement. These hoists are placed on hoist supporting structure with trestles, foundation anchors, stairway walkway and hand railing complete in all respect in accordance with the specification.

Gantry Crane

Electrically operated travelling Gantry Crane of suitable capacity used for operation of Stoplog Gates etc., Gantry Crane are including Gantry Crane are including Gantry Frame, hoisting and travelling equipment and cable reeling drum, wire ropes, drums, shafts, gearing arrangement, brakes, motors, digital position indicator in the operators cabin, limit switches for LT as well as centering the crane at each bay, gantry limit switch, spring buffers, control panels, cable, rail and fixture end stoppers complete in all respect.
