Textile strength testing equipment is provided comprising a generally horizontal immovable floor having formations typically in the form of rails that operatively anchor one or more feet of each of multiple columns spaced apart with the horizontal positions of individual columns being adjustable. The upper ends of the columns are provided with attachment means for attaching a textile test specimen thereto. A centrally positioned generally vertical pneumatic or hydraulic ram is provided for moving a textile engaging structure generally vertically upwards beyond the level of upper ends of the multiple columns. The height of the columns is from about 1 to about 2. metres and the size of the floor is up to about 7.5 m by about 7.5 m or more. Preferably the floor has inwardly lipped channel sectioned rails embedded in a concrete floor with the rails radiating from a central position in which the ram is located towards the centres of each side of a square floor and towards the four corners thereof. The pneumatic or hydraulic ram is accommodated in a generally vertical well that may be a suitable prefabricated vertical concrete pipe buried in a suitable excavation at the centre of the floor. |
