ZLD series hydraulic bolt tensioner

Product catalog summary

Overview: This document provides technical specifications for two series of hydraulic bolt tensioners designed for bridge applications: the ZLD series and the SJD series. These tensioners are engineered to deliver high tensile force and are equipped with features to enhance safety and efficiency.

ZLD Series - Hydraulic Bolt Tensioner:

Specifications: The ZLD series includes models ranging from ZLD30 to ZLD64, with tensile forces from 422 KN to 1830 KN. Bolt sizes range from M30 to M64, and the maximum working pressure is 150 MPa.
Design Features: These tensioners feature an automatic return mechanism, a red overstroke warning line for safety, and a polished surface treatment. They are designed to be high pressure and lightweight, with the capability to accommodate different bolt sizes.

SJD Series - Hydraulic Bolt Tensioner for Bridge Lock Clamping:

Specifications: The SJD series includes models from SLD30 to SLD64, with tensile forces from 422 KN to 1830 KN. Bolt sizes range from M30 to M64, and the maximum working pressure is 150 MPa.
Design Features: Similar to the ZLD series, these tensioners are designed for high pressure and lightweight applications, with an automatic return mechanism and safety features such as a red overstroke warning line.

Key Features Across Both Series:

Maximum working pressure of 150 MPa.
Automatic return mechanism for ease of use.
Red overstroke warning line to ensure operator safety.
Polished surface treatment for durability.
High pressure and lightweight design.
Versatility in bolt size accommodation.
