Hydraulic Cassette Wrench 

The TW‑H Hydraulic Cassette Wrench is one of the most advanced tools for tightening and loosening large bolts and nuts in the oil, gas, petrochemical, and industrial sectors. This series, with its low-profile design and narrow body, provides high torque in confined spaces. The working pressure of the device is 700 bar, and its torque repeatability is ±3%, making it a reliable option for sensitive and repetitive applications.

Capacity and Models

The TW‑H wrenches are available in five models, each covering a different range of torque and nut sizes. The smallest model, H27, generates a torque range from 260 to 3,060 Nm, while the largest model, H430, can apply a torque of up to 48,500 Nm. The nut size range for the cassettes in this series is from 19 to 175 mm. The combination of torque and large dimensions has made these products suitable for almost all industrial needs.

Low-profile design and access in confined spaces

The narrow body and low-profile design of the TW‑H allow for work in very confined spaces, such as flange bolts or connections near obstacles. The oil inlet has a 360-degree rotation capability, making it easy to use the device at various angles. The hexagonal cassettes of these wrenches are designed to be modular and can be quickly replaced with a pin; this feature saves time during installation and cassette replacement, making the process easier.

Material and Durability

The TW‑H wrenches are made from lightweight and durable aluminum alloy, ensuring low weight while maintaining strength. The impact-resistant and abrasion-resistant body makes these tools suitable for use in harsh industrial conditions. This series is manufactured according to international standards and has been certified by reputable organizations such as TÜV Rheinland.

Key Features

• Precise Torque: Torque repeatability of approximately ±3% to ensure consistent tightening of bolts.
• 360-Degree Port: The oil inlet with 360-degree rotation capability makes it easy to use in various positions.
• Interchangeable Cassettes: The ability to change cassettes and use square or Allen adapters for different bolts.
• Low-Profile Design: Narrow and low-height body for accessing bolts in tight spaces and near obstacles.
• After-Sales Service: Providing repair, calibration, and spare parts supply for TW‑H products.

Applications

This set of wrenches is used in various industries, including oil and gas, petrochemical, power plants, pipelines, metal structures, shipbuilding, and heavy machinery maintenance. The high torque of these tools allows engineers to tighten or loosen large and resistant bolts with high precision and speed.
