Dynamometers Tension Load Cells

ABQ Industrial offers a comprehensive line of Mechanical, Digital, Bluetooth, and Wireless Telemetry Dynamometers and Load Cells from industry-leading manufacturers Dillon and Crosby / Straightpoint. Engineered for critical overhead lifting, wire rope and utility cable tensioning, structural proof-load testing, marine mooring, and center-of-gravity (CoG) verification, our instruments provide NIST-Traceable accuracy from 100 kg (220 lbs) up to 500 tonnes (1,100,000 lbs).

Whether your operation requires a battery-free mechanical dial Dynamometer for extreme-temperature field work, an ATEX/IECEx intrinsically safe wireless load cell for offshore oil and gas zones, or a multi-sheave running line tensiometer for continuous cable pulls, our catalog delivers the exact safety factor, environmental sealing, and telemetry output required for job-site safety and compliance.

Precision Load & Tension Measurement by Industrial Application

Selecting the right Dynamometer or load cell depends on whether your load is static or moving, whether the operator has direct line-of-sight to the rigging point, and the environmental classification of your work zone:

1. Heavy Rigging, Overhead Lifting, Proof-Load Testing & Hazardous Zones (ATEX / IECEx)

High-capacity crane lifts, water-bag proof testing, and multi-point rigging arrays require link-style tension load cells and load shackles that keep operators at a safe distance from suspended loads.

• Self-Indicating Digital Link Dynamometers: For direct on-body LCD readout with push-button tare and peak hold, choose the Dillon EDjunior Digital Dynamometer (2,500 to 25,000 lbf, ±0.2% accuracy), the Straightpoint SID6T5 Digital Dynamometer (6.5t / 14,300 lbs), or the heavy-duty Straightpoint LoadLink Plus Digital Dynamometer (capacities up to 300 tonnes / 660,000 lbs, ±0.1% accuracy).


• Long-Range Wireless Telemetry Dynamometers: Monitor loads remotely up to 600 ft (183 m) or 3,280 ft (1,000 m) away using the Dillon "Red" EDXtreme Dynamometer (up to 550,000 lbf / 250,000 kgf, 5:1 safety factor) paired with the Dillon EDX-COMM-II Remote Communicator, or the IP67 waterproof Crosby Straightpoint RLP Radiolink Plus Wireless Dynamometer (1t to 500t / 1,100,000 lbs).


• Bluetooth Dual-Display & Smartphone App Rigging: Combine an integrated display or compact link with iOS/Android Bluetooth reporting using the Dillon EDXtreme-Blue Digital Dynamometer (2,500 to 25,000 lbs, 0.1% accuracy) or the Straightpoint BlueLink Bluetooth Dynamometer (6.5t / 14,300 lbs, 328 ft / 100 m Bluetooth range).


• Explosion-Proof & Low-Headroom Rigging: For Zone 0, 1, and 2 hazardous oil, gas, and chemical environments, deploy the intrinsically safe Straightpoint ATEX / Ex IECEx Radiolink Plus Wireless Dynamometer (up to 300t). Where vertical headroom is restricted or a permanent pin path exists, select Straightpoint Shackle Load Cells (Loadshackles) built on Crosby 2130/2140 shackles or custom Straightpoint LP Cabled or Wireless Standard Loadpins (500 kg to 1,500 tonnes).

2. Utility Line Stringing, Telecommunications, Guy Wires & Traction Testing

Outdoor utility linemen, telecom tower crews, and field engineers often work in sub-zero or remote environments where battery-free operation or rapid tension verification is critical.

• Battery-Free Mechanical Traction & Tension: The industry-standard Dillon AP Mechanical Dynamometer provides 100% mechanical, battery-free operation across temperatures from -50°F to 140°F (-45°C to 60°C) with ±0.5% accuracy, a maximum peak-hold indicator pointer, 5" or 10" anti-parallax dials, and capacities from 500 to 100,000 lbs (200 to 50,000 kg).

3. Running Line Cable Pulling, Marine Mooring, Hoist Overload & Chain Lashing

When a wire rope, synthetic rope, or chain is in continuous motion—or lacks a dead-end anchor point to insert a link Dynamometer—specialized inline and clamp-on sensors measure tension without cutting or dead-ending the line.

• Heavy Marine, Winch & Dockside Running Lines: The 5-sheave Straightpoint TIMH Running Line Tensiometer measures live tension, line speed, and rope pay-in/pay-out on wire ropes up to Ø 52 mm (2") across capacities from 10t to 80t (with cabled, 2.4 GHz wireless, or Bluetooth output).


• Electrical Cable Pulling & Synthetic Rope Erection: The lightweight, IP67-rated 5-wheel Straightpoint CableSafe Rope Tension Meter monitors electrical cables and synthetic fiber ropes (Ø 4 mm to 30 mm, capacities up to 10t) at speeds up to 600 m/min via Bluetooth to prevent cable elongation or gin-pole overload.


• Transport Lashing & Hoist Wire Rope Overload Protection: Monitor tension along 10 mm tie-down, towing, and sling chains via Bluetooth with the Straightpoint ChainSafe Chain Load Cell, or prevent crane/elevator hoist overloads and slackline conditions with the Dillon CraneGard Clamp-On Load Cell.

4. Under-Hook Crane Weighing & Shipping/Receiving Verification

Convert overhead shop cranes, hoists, and tripods into precision digital weighing stations:

• Heavy-Duty Shop Floor Crane Scales: The Dillon BCS Digital Crane Scale features an ultra-bright 1.4" (35 mm) LED display, built-in swivel hook, upper shackle, infrared remote control, and rechargeable battery/AC operation in capacities up to 10,000 lbs (5,000 kg).


• Compact Under-Hook & Tripod Weighing: The ASME B30.26 compliant Straightpoint MWP MiniWeigher Plus Compact Crane Scale offers ±0.1% accuracy, a 90 dB audible setpoint alarm, and RS-485 output in capacities from 100 kg to 5 tonnes.

5. Structural Compression Testing, Hydraulic Rams & Center of Gravity (CoG)

When loads must be measured under compressive force rather than tension—such as jacking heavy plant equipment, hydraulic ram verification, or structural weighing:

• Self-Indicating & Wired Compression Load Cells: Choose the Straightpoint LBP Loadblock Plus Compression Load Cell with an integral LCD readout, or the stainless-steel Straightpoint NI-Compression Wired Compression Load Cell for multi-point structural weighing.
