Auditorium lift:

BMU (Building Maintenance Unit): a device used to assist in the maintenance of large structures (skyscrapers, stadiums, etc.). See here

Bolster extensions:

Building Dynamics: architecture that is adaptive, interactive, reflexive and responsive ; also called kinetic architecture. See here

Car lift:

ChainLift: the classic time-tested SERAPID ChainLift is the proven technology for the vertical movement of heavy loads. It is mainly used in the industry sector. See here

Chain Mail: the bimonthly SERAPID newsletter that has all the news about the Group. Exclusive articles about our news and recent projects, our products and our events. To subscribe, go here

Die table: a staging table for die change, it typically has rollers and a push-pull mechanism mounted on top to assist in removing and inserting dies. These units can be fixed in place or portable. See here

DMX: DMX Controllers control multiple lighting and audio fixtures for stage production. SERAPID Telescopic Masts are available as DMX compatible units. See here

EN81: one of two new European standards for the design and manufacture of lifts, introduced in August 2014. Our systems are compliant with applicable standards under the Machines Directive 2006/33/CE, the Lift Directive 2014/33/UE, standards EN 81-20:2014 and EN 81-41. See here

End Stage: a thrust stage extended wall to wall, like a thrust stage with audience on just one side, i.e. the front.

EventPodium: a compact, travel-durable stage lift for in-performance use, specially designed for touring shows. See here

Fixed and removable die clamps: fixed clamps allow the die change process to be fully automated and are permanently built into the press bolster, which requires standardised press interfaces. Removable clamps are manually inserted, allow for more flexibility in die interface, but do not allow for full automation. See here

GPO (Gerbeur Porte-Outils in French): the SERAPID die stacker truck is a die handling machine for moving heavy dies from storage to the press and back. The system is all-in-one and easy to handle. See here

Goods Lift:

HDLift: the same concept as the classic ChainLift but designed for the most demanding industrial environments, good for high frequency applications of over 15 cycles/hour and a minimum service life of 1 million cycles at maximum load. See here

Hydraulic actuators: hydraulic systems use an incompressible containerised fluid to transmit force. Drawbacks are limited acceleration, extra space requirements, fluid leakage, environmental concerns and reliance on fossil fuels.

Kinetic architecture: a concept through which buildings are designed to allow parts of the structure to move, without reducing overall structural integrity. See here

Lead screw actuators: this technology uses a threaded nut, which is driven via the screw thus translating rotary motion into linear movement. Drawbacks include surface wear which reduces the system’s life cycle; limited speed, stroke and load capacity.

Lifts Directive: (2014/33/UE)



Machinery Directive: (2006/42/EC)

Meridian lift: a large circular stage platform lift with or without additional centre lifts. See here

Orchestra lift:

Proscenium stage: possibly the most recognisable type of theatre arrangement, an end stage with the front playing area framed picture-like by a structure known as the proscenium.

Push-Pull system: this die-positioning system makes it possible to accurately position the die by pulling it into the press or pushing it onto the loading equipment, and can be easily retro-fitted. See here

QDX (Quick Die eXchange): the SERAPID brand of quality products and systems for the quick die change. See here

QSX (Quick Seat eXchange): the SERAPID patented venue transformation system. Allows different seating configurations with straight or curved rows. See here

RCT (Rigid Chain Technology): a proprietary technology based on an interlocking chain link design that keeps the chain completely rigid while in use with the chain coiling back into a compact space when withdrawn. RCT is only available from SERAPID. See here


Rigid Chain actuators: these electromechanically driven actuators use Rigid Chain Technology to transmit force and move loads. The systems have a remarkable stroke and load capacity and are eco-friendly. The actuator is telescopic, only occupying the active space when in use. See our range here



SCT (Silent Chain Theatre): SERAPID’s scenery movement system. This low-noise horizontal system moves scenery by attachment to a chain system fixed in tracks under the floor. See here

SERAPID: the word “SERAPID” is the contraction of 2 French words “Serrage” and “Rapide” which means "quick tightening". Patented name of the Group.

SMED (Single Minute Exchange of Die): a system to reduce dramatically the time it takes to complete equipment changeovers. SERAPID’s QDX range of products has what you need for SMED implementation. See here

Stage lift:

Stage wagon:

Storage magazine:

Stroke: the maximum distance a shaft travels from a fully retracted to a fully extended position.

Telescopic jib:

Telescopic mast:

Telescopic stand:

Thrust stage: a stage surrounded by audience on three sides with the fourth side providing the background.

TriMast: for lifting the heaviest loads within a compact space, this is a heavy-duty mast system that synchronises three SERAPID Telescopic Masts and reinforces its stability with a series of steel plates. See here

Truck Lift:

Vertical LinearBeam:
