Product Description

POIN is a professional manufacturer of concrete machinery and excavator attachments and accessories, with more than 20 years of production experience. POIN HG series concrete placing boom are designed from Putzmeister technology, through continuous upgrading and improvement, achieved perfect performance already.

POIN HG28 concrete placing boom is hydraulic climbing type which is ideal for high rise buildings, bridges and dams. HG28 CPB has three stick hydraulic placing booms made of high strength special steel,and easy assembly and disassembly with split frame ability, as well as safe and comfortable use with the advanced proportional hydraulic control system. HG28 has Full hydraulic drive, 360°slewing; “R”folding type of arms, the balance valve and solenoid directional control valve are imported from Germany Rexroth. Main components of the electrical system are imported from world famous companies such as France Schneider. There are two modes of operation: wired and wireless remote control.

Full Hydraulic Control, Excellent Performance

Full hydraulic control of all boom movements provides smooth, precise control.
The load sensing, proportional, pressure compensated hydraulic system provides accurate, predictable boom placement even during multi-function operation.

Rapid Installation

Extensive application of modular design technology and quick connecting components allows rapid assembly and hoisting of placing booms.

Globally Recognized, Intelligent Control System

The German manufactured Siemens programmable login controller (PLC) is equipped with local, wired or 100m ultra long distance remote control.
This reliable system can be operated within four user selectable frequency bands.

Boom Cylinders are Equipped With Counterbalance Valves for Safety

The counterbalance valve provides a locking function as an added safety measure.

Delivery Pipe Service Life Increased 3-5 Times

The use of double-wall, wear-resistant delivery pipe has improved the service life up to 30,000-50,000m³.
This is 3-5 times longer than the life of ordinary pipe.

Two models of Climbing

Inner-climbing frames: floor frames or wall (lift or shaft) frames, which are suitable for different job sites.
