Product Description

With solid steel cross-heads from 3-6in (76-152mm) thick on our standard frames, Gilson load frames are the stiffest in the industry. The frame is among the few meeting the stringent ACI 363 rigidity recommendations. This 250,000lbs (1,112kN) Concrete Compression Testing Machine is equipped for testing 6x12in (152x302mm) cylinders, but may be outfitted with accessories to accommodate many different sized cubes, cores, beams and cylinders. The Load Frame Mounting Stand is optional for this unit. The mounting stand is placed in the lower platen at the correct height for safe, efficient handling of specimens. Includes latchable steel Fragment Guard Doors. The controllers is side-mounted.

The hydraulic ram applies compression force from the top crosshead. Precision ground piston with O-Ring sealing and Teflon back-up ring rests in a polished steel cylinder.  The lower platen is 6.5in (165mm) diameter. Locking stem holds upper platen assembly securely in place, yet allows for quick substitution of accessory components.

The two-stage, oil-immersed pump drives the hydraulic systems. The first high volume, low-pressure stage rapidly advances the piston. The pump automatically switches at 135psi of pressure to the second stage of low volume, high pressure flow used during testing to maintain a continuous rate of loading from 2,000-200,000lbf per minute with the value set in its Metered Advance Position. Hold feature pauses pressure advance indefinitely and Retract feature releases pressure to allow return of piston to starting position. A high-pressure hydraulic safety valve prevents use beyond maximum machine capacity. A pressure bleed hole in the piston helps avoid overextension of the ram. Our unique 1/2hp system runs cooler and offers better load control and is the quietest available. Operates on 115V/60Hz power supply.

The Pro controller is economical, but has high-end features. It simultaneously displays both live load and rate of load during testing. Peak load and average rate of load are displayed automatically at test conclusion and held until reset. Up to 700 tests can be stored in memory with date and time, sample I.D., peak load, and average rate of load data for later downloading to a PC or serial printer.

A high sampling rate and digital filtering result in smooth, uniform control of load pacing. Accuracy is generally better than ±0.5% of indicated load from 1% through full capacity, exceeding ASTM C 39 and E 4 requirements. The 5.3in (135mm) wide backlit VGA liquid crystal screen has a 240x64 pixel display area and adjustable contrast settings. Test data is displayed in user selectable engineering units of lbs, kN, kg, or N, and rate of load is shown in force units per second.

The Pro Controller is made in the USA and features a two-year manufacturer's warranty, and is housed in a sturdy stainless steel, NEMA-4 rated moisture and dust-proof enclosure to resist the harshest environments. The Pro is UL, CUL, CE, and Measurement Canada listed.
