GLZ-14C Self-feeding Shotcrete Machine

Its chassis is customized according to the construction requirement of the tunnel, applying the idea of platformization development by the senior engineer specially designing Dongfeng chassis. The front and rear axles are both strengthened, and its spare parts have the high interchangeability with that of Dongfeng automobile, which is easy for maintenance.

  • System working pressure:13MPa

  • System flow:46.7L/min

  • Hydraulic oil tank volume:100L

  • Concrete delivery capacity:14m³/h


Continuous feeding, high working efficiency

Feeding hopper works together with lifting hopper to ensure continuous feeding, and spraying capacity up to 14m³/h, efficiency is greatly improved.

Dry shotcrete machine slide easily on the rail and work efficient

The dry-mix shotcrete machine can slide easily in the track, and the feeding hopper is lifted by hydraulic control, lowering the labor intensity of maintainers.

Four hydraulic outriggers

The four hydraulic outriggers make the machine more stable, firmer and safer for construction site.

The lifting hopper can automatically stop

The Oil cylinder stops working when the hopper has reached specified height, which extend service life of cylinder, reduces oil consumption and saves cost.

The feeding hopper can be opened and closed easily

The feeding hopper can be opened and closed easily, the feeding amount can be automatically adjusted according to the working capacity of the dry shotcrete machine, eliminate manual adjustment.

Accelerator adopts automatic device

The design of accelerator automatic adding device is new and reasonable, to realize continuous and uniform feeding, stepless speed regulation, reduce labor cost.

The braking mode is air brake

The braking mode is air brake, make driving and parking easier and safer.

Easy and safe feeding

A special work station is reserved for feeding accelerator, making the operation easier and safer.

Easy operation

ON/OFF switches have been provided at the two sides of the machine for easier operation.
