  • Page 2: Introduction

    INTRODUCTION This section explains how to mount a car on the Wedge Clamp Anchoring System. The anchoring system is designed to let you make multiple pulls to a car without changing the anchoring attachments and without damaging the car in the pulling process. An important component of the Wedge Clamp System is the specially designed pinchweld clamps.
  • Page 3 The pinchweld clamp is not a continuous clamp – the jaws cover an area of 200 mm with a 75 mm cutout in the center. This cutout allows the clamp to fit around obstructions such as fender bolts, flanges, etc. The two smaller jaws allow for a greater biting force than a single large jaw.
  • Page 4 The Wedge Clamp System is available in two different anchoring options: the chain anchoring system, and the chainless anchoring system. The difference between these two systems is the way the anchoring system is secured to the floor. The chainless system fastens to the floor with cast aluminum stands which attach to rails on the floor.

  • Page 6: Set Up Procedure

    Tools Required 1. Floor jack 2. 2 - safety stands 3. Air wrench with a 3/4” socket 4. Hammer (3 lbs or 1.5 kg) 5. Open or box end wrench – 1 1/8” (29 mm) Set Up Procedure When setting up the Anchoring System for the first time it is important that you check for uneven floor conditions.
  • Page 7 If you find that a significant adjustment was required to make the two crossbars parallel then you should remember which stand goes at each end of the anchoring rails to maintain the bolt adjustment you have made for future anchoring setups. In any event, it is useful to check that the crossbars are parallel by sighting along the bars after completing each anchoring setup on the vehicle.
  • Page 8 e) Tighten clamp jaws with air wrench a little tighter than a wheel nut, approximately 90 ft. lbs. (120 N.m) of torque. f) Repeat on opposite side. The pinchweld clamps should be positioned along the pinchweld within 1 inch (2.5 cm) of each other, from side to side. 2.
  • Page 9 3. Install anchoring stands: a) Position the anchoring stands under the anchoring crossbar. Always position the Chainless Anchoring Stands so that the bolt adjustment is correct to counteract for any uneven floor conditions as described on Page 5. NOTE: If your floor jack does not raise the vehicle high enough to allow the anchoring stand under the end of the anchoring crossbar, then hang the stands on the ends of the anchoring crossbar (as shown at the left) by the hole in the stand.
  • Page 10 c) Remove the safety stands and lower the car onto the anchoring stands. d) Raise the rear end of the vehicle and repeat same process as at the front: • place the rear clamps on the car positioned on the pinchweld within 1” of the clamp on the other side of the car.
  • Page 11 6. Install wedges through the top of the anchoring stand – to lock in the anchoring crossbars and hammer into place. CAUTION: Before disassembling the anchoring system you must first remove the wedges at the top of the anchoring stands, otherwise sill damage will occur. 7.

  • Page 12: Using The Mobility Wheels

    Using the Mobility Wheels A car can be moved while mounted on the Wedge Clamp System by using the mobility wheels. To install the wheels remove the wedges from the top of the anchoring stands, and raise an end of the car. Wedge the mobility wheels onto the anchoring side bars. Always install the two swivelling wheels away from the heavier end (engine end) of the vehicle.

  • Page 13: Removing A Car From The Chainless Anchoring System

    ANCHORING SYSTEM To remove a car from the anchoring system, reverse the set up procedure by following the instructions below. Chainless Anchoring System 1. Loosen the rail lock nuts and remove the rail spacer wedges from all four anchoring stands.

  • Page 14: Anchoring Problems And Solutions

    ANCHORING PROBLEMS AND SOLUTIONS This section describes procedures for handling special anchoring situations with vehicle models that are difficult to anchor, vehicles without pinchweld flanges, or vehicles with certain damage conditions in the pinchweld area. WARNING: Serious damage or injury can occur if a vehicle is not anchored securely for pulling.
  • Page 15 With the hundreds of different unibody models on the road today there is no single procedure for securely anchoring all of these vehicles. Many car manufacturers provide no proper anchoring points for collision repairs. The pinchweld flange that is formed beneath the sill (rocker) panels where key structural components are welded together is usually a reliable point to anchor a unibody car.

  • Page 16: Anchoring To Weak Pinchwelds

    Anchoring to Weak Pinchwelds Pinchwelds vary from car to car. Some have good strength for heavy sideway pulls but not for down pulls. On other cars, the pinchwelds might be strong at the front but weak at the rear. Careful examination can usually determine what the limitations of the car’s pinchwelds are.

  • Page 17: Anchoring To Offset Pinchwelds

    Anchoring to Offset Pinchwelds If the pinchwelds do not run in straight line for their full length it is said that a vehicle has offset pinchwelds. The left and right pinchwelds may angle in towards the center of the car at one end or the other, or have a sudden step inward at one point along the sill (rocker) panel.

  • Page 18: Anchoring Wide Body Vehicles

    Anchoring Wide Body Vehicles For extra wide bodies vehicles (usually of the van type) Wedge Clamp has developed adapter brackets for the pinchweld clamps. Each adapter extends the pinchweld clamp by approximately 4” (100 mm) to widen the anchoring system 8” (200 mm). Examples of vehicles which require these brackets are the Ford Aerostar vans and the General Motors Astro vans.

  • Page 19: Anchoring Cars With Sill Damage

    Anchoring Cars with Sill Damage This procedure is used for fitting the Wedge Clamp Anchoring System to a vehicle that has received minor sill damage: Anchoring cars with Minor Sill Damage 1. Raise the front of the vehicle and attach pinchweld clamps to a section of the pinchweld flange if possible.
  • Page 20 7. After the repair has been done a comparison check with the undamaged side can be done by measuring from an underneath control point to the edge of the pinchweld. 8. Set up the remainder of the anchoring system as normal. Anchoring Cars with Major Sill Damage When the sill (rocker) area of the car has been so severely damaged that the pinchweld clamps cannot be bolted to the sill on the damaged side of the vehicle use...
  • Page 21 Replacing a Sill (rocker) Panel NOTE: In situations where the sill (rocker) panel needs to be replaced, mount the pinchweld clamp on the crossbar facing inwards (i.e. reversed 180 ) on the damaged side and remove the clamp jaws. Position the clamps on the damaged side so that the half jaw of the clamp is as near as possible to the inside of the pinchweld flange.
