Product Description

Pipelayer (Long Distance Pipeline Construction Equipment)

Product Description

HGY pipelayer is mainly used for pipe hoisting operations in pipeline construction, such as pipe transportation, pipe laying, assembly and trenching. The pipelayer chassis is a special hydraulic chassis for developed on the basis of mature excavator chassis technology. The traveling system adopts hydrostatic transmission mode, with small impact on start and stop, and can realize in-situ steering; The lifting system adopts full hydraulic transmission, with stable transmission and good micro motion performance. Compared with the traditional bulldozer chassis pipelayer, it has obvious technical and application advantages.

HGY Pipelayer can adapt to the working environment of - 20 ~ + 50 , the altitude below 3000m, the environment with less than 5% sand and dust in the air and all kinds of weather such as rain, snow and fog; Be able to operate safely and reliably on a 30 ° ramp.
HGY pipelayer has reasonable design, compact structure, easy dispatch, transfer and transportation, and can meet the requirements of railway transportation and self-crawling flat trailer transportation. Adapt to the construction site and general road operation.

Product Features

I. Chassis Assembly Features

1, Adopt hydraulic excavator chassis technology, high-strength pipelayer special chassis, with reliable quality.

2, Three rib or double rib crawler, nine groups of supporting wheels, and the maximum 30° climbing angle.

3, The main pump, slewing motor and traveling motor adopt the German Rexroth brand to ensure the reliable operation of the hydraulic system of the whole vehicle.

4, The main valve adopts full electric control solution, which can operate smoothly and realize accurate optimization.

5, Adopt high-strength connection structure between the walking frame and the vehicle frame to ensure that the whole machine has sufficient stiffness during lifting.

6, With increased gauge design, improving the stability of the whole machine, more suitable for the side loading condition.

7, 9 supporting rollers are distributed on each side, with large bearing capacity, high temperature resistance and adaptability to the harsh working condition.

 

 

II. Safe and reliable braking of driving system
