Auto Smart Maneuverable Hook Wrench

1. The internal combustion engine bolt spanner adopts oil-immersed tooth-embedded helical friction clutch torque, which greatly improves the lubrication conditions of the upper and lower clutches, and reduces the wear of the tooth surface to the smallest degree, and solves many technical difficulties and defects of tooth-embedded helical friction clutches in the practical application.

  2. The gearbox body adopts aluminium alloy casting, which not only further reduces the weight of the whole machine, but also realises the fully enclosed oil lubrication method, which is fully adapted to the operation under the harsh working environment such as wind and sand.

Scope of Application

JGB-Ⅲ Maneuverable hook wrench is suitable for the installation and disassembly of railway fastener. The machine is double head, which can install two fasteners or dismantle two fasteners at the same time. It has high efficiency, accurate fastener installation, convenient disassembly, centralized control and simple operation. It is an indispensable necessary equipment for overhaul and rail change.

3.1 Working principle:

Installation of fastener: driven by gasoline engine, driven by centrifugal clutch, gear pump is driven. High pressure hydraulic oil is transmitted to oil cylinder through three position four-way electromagnetic directional valve and safety valve, and the plug is driven by oil cylinder to install or remove elastic strip to sleeper

3.2 basic structure:

3.2.1 hydraulic pump station
