Freyssi Flat Jacks are simple, practical devices for the civil or structural engineer wherever the application or control of large forces is required. Flat jacks are frequently used in the solution of unforeseen problems such as in remedial measures or structural additions.
Synchronous Lifting Systems
The sensor extension is different from the Cylinder stroke value. The sensor extension is hooked to the load, and it has a value even when the Cylinder is collapsed. The potential applications of this system are numerous synchronized lifting levering, pushing, pulling and positioning using computer technology.of a synchronous lifting system
The Model 3000 Load Cell is made from an annulus of high-strength steel or aluminum, with electrical resistance strain gages in a Wheatstone Bridge configuration. The load cell is designed primarily for use on tiebacks and rockbolts, although they may be used during pile load tests and for monitoring loads in crosslot struts and tunnel supports, etc. In most cases, the load cells are used in conjunction with a hydraulic jack and bearing plates.
Monostrand Stressing Jacks
Power Team Monostrand Stressing Jacks are the most durable in the industry.
Monostrand Stressing Jacks suited for work on slab-on-grade where dirt, heat and high volume use take their toll.
Stressing jacks are mainly used on construction sites for stressing mono-strand anchors, and for the separate stressing of the strands of multistrand tendons.
We can provide customized jacking equipment to test driven piles from 1 -2000 tons. The systems can be manually, electrically or automatically controlled.
WB Equipment has delivered components for multiple jacking systems. Our knowledge of structural design, hydraulics, and automation means that we are capable of designing a complete jacking system with controls that allow for fully automated jacking and monitoring.
Hydraulic Torque Wrenches
A hydraulic torque wrench is a power tool designed to exert torque on a fastener to achieve proper tightening or loosening of a connection through the use of hydraulics. A torque wrench is applied to the nut either directly or in conjunction with an impact socket. Hydraulic torque wrenches apply a predetermined, controlled amount of torque to a properly lubricated fastener.
A strand jack (also known as strandjack) is a jack used to lift very heavy (e.g. thousands tons or more with multiple jacks) loads for construction and engineering purposes.
Strand jacks can be used horizontally for pulling objects and structures, and are widely used in the oil and gas industry for skidded loadouts. Oil rigs of 38000 tons have been moved in this way from the place of construction on to a barge. Since multiple jacks can be operated simultaneously by hydraulic controllers, they can be used in tandem to lift very large loads of thousands of tons. Even the tandem use of two cranes is very difficult operation.
The hydraulic press depends on Pascal’s principle: the pressure throughout a closed system is constant. One part of the system is a piston acting as a pump, with a modest mechanical force acting on a small cross-sectional area; the other part is a piston with a larger area which generates a correspondingly large mechanical force. Only small-diameter tubing (which more easily resists pressure) is needed if the pump is separated from the press cylinder.
Custom Center-Hole Cylinders
Custom made cylinders made to your specifications. All cylinders calibrated and traceable back to NIST. Centerhole, locknut, low height, single acting, double acting, long stroke.
- 0-1500 tons
- Centerhole sizes .75 inch to 15 inches
- Stroke ½ inch to 10 feet
Quick acting re-bar grips are available for pull out testing of reinforcing bars in concrete, (re-bar/reinforcement bars) used in construction of highways, bridges, and tunnels as well as rigging and other applications.
When used with hydraulic jack, user slips jack and grip over grouted re-bar and applies pressure to load. These re-bar grips come in sizes No. 4-18 and accommodate construction industry’s focus on repair, maintenance, and building of public infrastructure.
A jack, screwjack or jackscrew is a mechanical device used as a lifting device to lift heavy loads or to apply great forces. A mechanical jack employs a screw thread for lifting heavy equipment.
Hydraulic & Mechanical Flange Spreaders
Integrated wedge concept: friction-free, smooth, parallel wedge movememtn eliminates flange damage and spreading arm failure
Unique interlocking wedge design: no first step bending and risk of slipping out of joint
Requires very small access gap of only .24 in. (6mm)
Stepped spreader arm design: each step can spread under full load and few moving parts means durability and low maintenance
Safety block SB1 and ratchet spanner SW22 included
