SCHWING® SP305 Trailer-Mounted Concrete Pump (PDF 1.28MB)

  • Output to 30 cubic yards per hour
  • Pressure to 642 psi
  • 1.0" Maximum Aggregate Size

Twin cylinder open loop all-hydraulic concrete pump provides smooth output up to 30 cubic yards per hour with industry leading fuel efficiency. A transfer tube valve is chosen for versatility and operates reliably with minimal maintenance pumping grout, shotcrete or concrete.

The SP305 is the logical upgrade from a ball-valve pump. Hydraulically driven components apply up to 625 psi on the material to achieve impressive horizontal and vertical distances. The SP305 will provide fast return on your investment when you take on more projects thanks to the pumps ability to handle up to 1" aggregate mixes. The lightweight and compact size of this pump makes it very portable for multiple pours in a day. Ease of operation makes the 305 a great entry-level pump that integrates into most contracting companies.

Rely on the 305 to expand your pumping horizons handling grout for block-fill, shotcrete and concrete. Many concrete contractors rely on the 305's ability to handle a variety of mixes while providing output to handle the majority of job requirements. Standard features include LED taillights and aluminum wheels for low maintenance and upgraded looks.

SCHWING® SP750/SP1000 Trailer-Mounted Concrete Pump (PDF 963KB)

  • Output to 70 cubic yards per hour
  • ressure up to 1100 psi
  • 1.5" Maximum Aggregate Size

This all-hydraulic concrete pump sets the standard for fuel-efficiency, reliability and performance. Twin circuit hydraulics combine with standard dual shifting cylinders, agitator and Long Rock ValveTM to provide smooth pumping of harsh mixes, shotcrete and grout. Fast cleanout adds more jobs per day with the lowest per yard operating costs.

The compact size of the SP Models means easy towing to the job. And fast cleanout of the Rock ValveTM adds more jobs per day for more profits. Schwing all-hydraulic design is the key to ultra-reliable operation.

Remote control (cable or optional radio remote) frees the operator to monitor the end hose and the pump. Critical functions including on/off and forward/reverse are at your fingertips.

Aliva®-257 Concrete Spraying Machine (PDF 1MB)

Dry - and Wet Shotcrete

With the newly developed, universal AL-257, dry and wet Shotcrete are equally possible. No changing on the machine from dry to wet shotcrete has to be performed. For changing from wet to dry shotcrete, the machine has to be cleaned and dried up. The integrated exhaust system and a newly designed hopper allow a high filling degree of the rotor chambers, which leads to low pulsation and less rebound.

Application and conveying capacity

With a weight of just 750 kg and compact measurements, the AL-257 fits on every site, is easy to handle around and adjusts itself to every application. With a huge spectrum of conveying capacity from 0.7-9.6 m3/h, there is no work which could not be conducted economically. For thin layer concrete renovation with the 2.5l rotor up to slope protection of an excavation with the 12l rotor, with the AL-257, one always has the right equipment at hand.

Aliva®-267 Concrete Spraying Machine (PDF 483KB)


The AL-267 is a multi-functional machine for wet and dry application of sprayed concrete in the thin steam method. The modular construction allows the right type for all requirements. With an output capacity of 4-21 m3/h the range of applications covers: Excavation-protection, rock stabilization, slope protection, swimming pool construction, hydropower projects, tunneling, mining, etc. Easy handling, flexibility and functionality are unique for the AL-267.

Aliva®-403.4 Liquid Dosing Unit (PDF 69KB)

The dosing unit Aliva®-403.4 for liquid accelerators enables an infinite setting of accelerator for small quantities.

The BASIC Version is equipped with a simple control which is done entirely on the dosing unit itself, i.e. the amount of additive is set manually by means of the dosing knob and thus cannot be synchronized with a concrete spraying machine.

The Aliva®-403.4 is most suitable for manual spraying together with the concrete spraying machines Aliva®-237/ Aliva®-257 and Aliva®-267.

Aliva®-403.6 Liquid Dosing Unit (PDF 193KB)

Features & Benefits

Bi-directional Drum Rotation

The mixer is driven hydrostatically over a planet gear. The necessary driving power is achieved by a variable axle piston pump enabling a continuously adjustable rpm regulation between 0 rpm to 14 rpm, in both turning directions. The bi-directional rotation of the remix drum allows variable mixing or discharge rate proportional to rotation speed. The drum speed is controlled by two proportional joysticks, one at the discharge end of the drum, the other at the operator's position on the vehicle.

Internal Drum Flutes

Provide remixing and material discharge without tilting the drum. This allows low profile operation and discharge, and allows the drum to be self-cleaning, eliminating the requirement to tilt the drum.

Oval Loading Hatch

Front to rear, allowing truck to be jockeyed for optimum loading.

High Load Capacity Bearings and Rollers

The large bearings of the gearbox and the two rollers mounted at the discharge end of the drum form a three point support system that allows the vehicle frame to flex without transmitting the flexing to the body of the drum. The discharge door is opened externally by means of hydraulic control levers operating the external cylinder. The chute is hydraulically powered for both tilt and swing movements. The discharge door seal is fabricated from hardwearing polyurethane material.
