{"title":"Pantographs","description":"\u003cp\u003e \u003cstrong\u003ePantographs\u003c\/strong\u003e are spring-balanced suspension systems used in film and TV studios to allow simple, precise height adjustment of lighting fixtures from an overhead bar or ceiling rail. Using a spring system, the pantograph can be balanced so that a light touch can readjust the height of the load through a series of connected diagonals that compress or extend to raise and lower the fixture.  They keep studio floors clear of stands and cables, making them a standard solution in broadcast, photography and film studio environments. \u003c\/p\u003e \u003cp\u003e Part of our \u003ca href=\"https:\/\/shopmtn.co.uk\/pages\/entertainment-stage-rigging\"\u003eentertainment and stage rigging\u003c\/a\u003e range.

The spring mechanism counterbalances the weight of the fixture below, allowing the height to be adjusted by hand and locked off at the desired position. The bottom receiver accepts the lighting fixture via a spigot or bolt connection. \u003c\/p\u003e \u003ch3\u003eWhat to look for\u003c\/h3\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eSWL\u003c\/strong\u003e — Doughty pantographs are available rated at 12kg, 20kg, 27kg and 36kg; always match the rating to the fixture weight including any accessories\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eDrop distance\u003c\/strong\u003e — available in 2.2m, 3m, 4m and 5m drop lengths to suit different ceiling heights and studio configurations\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eTop connection\u003c\/strong\u003e — standard 28mm TV spigot top fits Doughty barrel socket clamps, TV quick clamps and studio rail receivers\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eBottom receiver\u003c\/strong\u003e — three-point receiver with sword pin allows 360° rotation and locks off securely; compatible with 28mm spigot, M12 bolt hole and half coupler fixing\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eTypical applications\u003c\/h3\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eBroadcast and TV studios\u003c\/strong\u003e — permanent ceiling-mounted lighting rigs with adjustable drop for varying set heights\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePhotography studios\u003c\/strong\u003e — overhead key and fill lights on studio rail systems, keeping the floor clear\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eFilm studio stages\u003c\/strong\u003e — flexible height control for practicals and fill lights on fixed grid systems\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e Also available: \u003cstrong\u003ebarrel trolleys\u003c\/strong\u003e for moving fixtures along studio rails without lowering them to floor level. \u003c\/p\u003e","products":[{"product_id":"doughty-braked-barrel-trolley","title":"Doughty Braked Barrel Trolley- Standard \u0026 Slimline Version","description":"\u003cmeta charset=\"utf-8\"\u003e\n\u003ch2 style=\"text-align: center;\"\u003e\u003cstrong\u003e\u003cspan\u003eBraked\u003c\/span\u003e Barrel Trolleys - Doughty Engineering\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eBarrel Trolleys are often used to suspend Pantographs from fixed or rolling pipe grids and barrel hoists.
