ZZ9400/26/55D Hydraulic Roof Support Project for an Underground Mine in Indonesia

hydraulic roof supportswere included in a procurement solution prepared by TAIDA GLOBAL on May 18, 2026, for an underground mining project in East Kalimantan, Indonesia.The project was designed for an underground mining company requiring high working resistance, a wide support-height adjustment range, and an electro-hydraulic control system.

Project date: May 18, 2026
Quantity: 48 units
Client: An underground mining company in Indonesia
Project location: East Kalimantan, Indonesia
Delivery location: Balikpapan, East Kalimantan, Indonesia
Product model: ZZ9400/26/55D Hydraulic Roof Support
Application: Underground mining face support

The ZZ9400/26/55D hydraulic roof support features a four-column chock-shield structure equipped with four main supporting columns.This model has a working resistance of 9,400 kN and a support-height range of 2,600-5,500 mm. It is suitable for underground mining projects that require support-height adjustment based on mining height and rock-strata conditions, provided that the actual operating conditions comply with the equipment’s technical specifications.

The center-to-center spacing between units is 1,750 mm, an important parameter for determining the arrangement of hydraulic roof supports along the working face. The equipment uses an electro-hydraulic control system to support the operation and coordinated control of its hydraulic functions.The product images show details of the hydraulic cylinders, sideguard jacks, pipeline connections, and main equipment structure. These components require comprehensive inspection before the units enter the delivery stage.
