SAFETY

• The TWC is heavy. Take care when installing.

• Ensure the operating area is capable of taking the weight of the TWC.

• Trapping hazard - Keep hands and loose clothing away from the torque wrench during use.

• To avoid damage to the torque wrench under test do not exceed the wrenches set torque value.

• To avoid damage to the transducer do not exceed the maximum capacity.

• Never exceed the maximum torque capacity of the TWC.

• Do not operate without a torque measurement system connected and working.

• The TWC is designed for testing torque tools, do not use for other purposes.

FEATURES AND FUNCTIONS

• Can produce certification to ISO 6789-2:2017 when used with T-Box XL™ software version 3.0.0.X and

TDMS version 4.0.X.

• Counter balance reaction is designed to support the weight of the wrench so that the weight does not

become a parasitic force within the calibration system. The floating nature of the support means that the

wrench is able to find its own natural level rather than being constrained as in many other loading

devices. Any such constraint will be a parasitic force within the system. Patents apply.

• Two speed gearbox designed for a sufficient balance of speed and control by allowing for both fast

loading of the torque wrench and a slower more precise loading.

• Lightweight alloy construction ensures the TWC is easily transported, making it suited for mobile

laboratory applications.

• Rotating transducer design ensures that the load is applied 90° to the torque wrench handle. The benefit

of this precise alignment is that forces are applied squarely to the load point of the handle.

• Compatible transducers include Flange Mounted Transducers, Static Transducers (when using part

number: 60318) and Pro-Test (when using part number: 60323)

Location

FIGURE 2 – Locating the TWC

1) Ensure location can cope with weight of loader.

2) Locate the TWC on a level surface at a comfortable working height.

3) Secure the feet to the bench.

Counter Balance Reaction Post Installation

Your TWC has been delivered with the reaction counter balance wheel assembly unattached to the reaction

assembly. This has been done to prevent damage to this assembly during transit.

FIGURE 3 – Disassembled Counter Balance Reaction Post Assembly

Place the counter balance wheel onto the top plate of the reaction assembly.

FIGURE 4 – Lining up the Counter Balance Reaction Wheel

Attach the counter balance wheel assembly with the two M4 socket cap screws from the underside of the top

plate of the reaction assembly. Tighten to 1 N·m.

FIGURE 5 – Attaching the Counter Balance Reaction Wheel

Assemble the weight carriage over the balance wheel.

FIGURE 6 – Counter Balance Reaction Assembly

Slide the “Counter Balance Reaction Post Assembly” on to the reaction rail.

FIGURE 7 – Sliding the Counter Balance Reaction Assembly onto the Reaction Rail

Set the locking lever to engage positively when applied. This is done by pulling the lever towards you whilst

at the same time winding in the screw with an appropriate screwdriver. When at top dead centre, the lever

should start to engage to lock the reaction post’s position. Turn the lever to the right and you should start to

feel some resistance as the lock is engaged. Before continuing check the reaction post assembly is securely

fixed in position.

OPERATING INSTRUCTIONS

Locating a Torque Wrench

Select the correct capacity transducer and secure to the platform with socket cap screws.

FIGURE 9 – Attaching a Transducer

Ensure the transducer has been fitted with the correct adaptor and place the torque wrench drive into the

transducer. Ensure that the torque wrench drive is fully engaged (see figure 10).

FIGURE 10 – Attaching a Torque Wrench

Set the reaction post position on the reaction arm so it is in the middle of the torque wrench handle (see figure 11).
