Loading Benches – FAQ & User Guide

Quick Answer

Mountz Loading Benches are mechanical torque wrench loading systems designed for calibration, verification, and presetting applications. They help improve repeatability by providing controlled torque application while reducing operator influence during testing and calibration procedures.

Who This Is For

Calibration technicians
Metrology laboratories
Quality engineers
Manufacturing engineers
Service and repair departments
Tool crib managers
Companies performing in-house torque wrench calibration
Facilities implementing torque verification programs

When Should You Use This?

Use a Mountz Loading Bench when:

Calibrating torque wrenches
Presetting adjustable torque wrenches
Performing torque verification activities
Establishing an in-house calibration program
Reducing operator-induced calibration errors
Improving calibration repeatability and consistency

When Should You NOT Use This?

A Loading Bench may not be the best fit when:

Torque wrench calibration is not required
The wrench capacity exceeds the loading bench capacity
Portable field verification is the primary requirement

How the Loading Bench Works

The Loading Bench provides a controlled mechanical loading system for torque wrench calibration and presetting.

The system:

Applies torque smoothly and gradually
Reduces operator effort
Helps minimize user-induced testing errors
Supports repeatable calibration procedures
Allows consistent loading during calibration and verification

Result:

Improved calibration accuracy
Better repeatability
Reduced operator influence
Easier torque wrench presetting
More efficient calibration processes

Core Features

Designed for torque wrench calibration and presetting
Controlled torque application
Adjustable reaction positions
Mountable to a bench or cabinet
Large hand wheel for smooth load application
Operates in clockwise and counterclockwise directions
Helps reduce operator effort during calibration procedures
Supports repeatable testing and calibration processes

Available Models

The Mountz Loading Bench Series consists of three laboratory-grade loading benches designed to support torque wrench calibration, verification, and presetting applications across a wide range of torque capacities. Each model shares the same smooth manual loading system, bi-directional operation, adjustable reaction positions, and compatibility with Mountz torque analyzers. The primary difference between models is maximum torque capacity and physical size.

Model Selection Guide

Need to calibrate torque wrenches up to 250 lbf.ft (340 N·m)?

Choose:
LB250F
Ideal for lower-capacity torque wrenches and compact calibration workstations.

Need to calibrate torque wrenches up to 1000 lbf.ft (1355 N·m)?

Choose:
LB1000F
Designed for medium-capacity torque wrench calibration while providing a larger reaction range.

Need to calibrate torque wrenches up to 2500 lbf.ft (3389 N·m)?

Choose:
LB2500F
Designed for heavy-duty torque wrench calibration requiring the highest loading capacity in the Loading Bench Series.

Which Loading Bench Should I Select?

Start with these questions:

What is the maximum torque wrench capacity you need to calibrate?
Will the bench be used for calibration, verification, or presetting?
What reaction arm travel is required for your torque wrench?
Will the bench be permanently mounted to a workbench or cabinet?
Which Mountz torque analyzer and sensor will be used with the system?
Will larger industrial torque wrenches be calibrated regularly?

The answers to these questions will help determine the appropriate Loading Bench model for your calibration program.

Setup & Operation

To use a Mountz Loading Bench:

Securely mount the loading bench to a workbench or cabinet (recommended).
Install a compatible Mountz torque sensor.
Connect the sensor to a compatible Mountz torque analyzer.
Position the torque wrench and adjust the reaction point to match the wrench length.
Apply torque gradually using the large handwheel.
Record calibration or verification results through the torque analyzer.

The smooth manual loading mechanism helps minimize operator influence while improving repeatability during torque wrench calibration and presetting.
