UNIVERSAL TESTING FRAME UMIB
This test frame is the basic component of the UMIB/W series machines. Formed by four main columns and manufactured as per the Standards:
UNE-7281, DIN-51220, 51222, 51223, 51227, 51228, ASTM-E4, BS-1610 and EN-10002-1 (1990).
ADVANTAGES OF THE TESTING FRAME
- The frame has a single test space, allowing several uses by interchanging testing devices.
- The four over dimensioned columns afford the machine a high degree of stiffness. The crosshead is locked tightly in place by a special plate-column friction system based on high-strength screws. The oil free system avoids the leak-tightness problems. The locking system is operated automatically by a hydraulic locking/unlocking device.
- The crosshead height can be adjusted with lateral hydraulic jacks. This improves the working conditions because the operator can adjust the compression testing space height to suit his needs.
- The test frame is accessible from all sides, making it possible to fit specimen feeding devices and automatic strain measuring systems.
- The large free distance between gripping heads (0 - 1000 mm, including the piston stroke) makes it possible to use devices for performing tests at high and low temperatures, and test large specimens without the need for modifications.
CONSTRUCTION The test frame consist of:
- A bedplate with a series of standardized holes for attaching the gripping devices and other devices for testing building components.
- A ground double-acting actuator mounted in the lower crosshead.
- Four chromium plated columns providing protection against corrosion and ease of maintenance.
- A height-adjustable mobile crosshead, locked with screws at the height required for the tests. The universal load cell (tensile-compression testing) is mounted on the upper crosshead. In series, on the lower part of the load cell, is mounted the upper gripping head with a ball-and-joint socket and a locking system for compression tests.
AUTOMATIC HYDRAULIC LOCKING/UNLOCKING CROSSHEAD ADJUSTEMENT SYSTEM
APPLICATIONS
This system complements the lateral hydraulic jacks which control the vertical movement of the crosshead. The screw-based locking system, manually operated with a torque wrench, is replaced by remote, push-button controlled hydraulic pistons which automatically lock and unlock the crosshead and, therefore, the upper gripping head.
ADVANTAGES
- The system allows fast positioning of the crosshead by means of a displacement transducer (LVDT) axially placed in the piston with 300 mm. of maximum stroke. This is particularly useful when testing different sized specimens.
- The lateral hydraulic jacks and complementary automatic locking/unlocking system can be used to tauten the specimen slightly before the test (very useful in particular for non-rigid specimens such as chains, cables, ropes, etc.).
- The crosshead does not move unless unlocked (safety protection).
EQUIPMENT
- Releasing cylinders, adapters and hydraulic pipes for connection to the high-pressure hydraulic power unit.
- Directional seat valve.
- Relief valve.
- Safety switch valve.
GRIPPPING HEADS
FAST ACTING
These heads are particularly suitable for low-frequency, positive-load static or dynamic tensile tests (shaped-wave tests exceeding zero point) of cylindrical or prismatic specimens, with or without a head and made of metal or any other material. Rated test load = maximum static test load: up to 600 kN
ADVANTAGES
- Fast-grip.
- Automatic wedge-grip.
- Guided-wedge centering.
- Fast and easy-to-change wedges.
- Front-accessible gripping space.
- Extensive gripping possibilities.
- Simple and easy to handle.
- Tempered and ground wedge guides.
- Wedge-holders for oscillating clamps for gripping deformed specimens.
HYDRAULIC
Specially recommended on the following cases:
- High load applications
- Complicated fastening sample
- Zero passing test
- Dynamic applications For any section specimens , with or without a head and made of metal or any other material.
Rated test load = maximum static test load: up to 1000 kN
