pile driving and extracting, guardrail installation and maintenance, low price, reliable quality, timely delivery, after service - details see: https://www.machineto.com/hydraulic-guardrail-excavator-post-driver-10113611

1. Functions

1.1 Pile Driving Function: MDB230 Hydraulic Guardrail Excavator Post Driver and Extractor (without the truck chassis) is fitted to the back for the truck or trailer to allow speedily installation. is specially designed for road maintenance work for road safety barrier and guard rail posts, its is easy to install on any type truck.

1.2 Pile Extracting Function: With the same equipment and hydraulic system for extracting poorly driven or incorrectly positioned posts or road maintenance work, it is a professional machine for extracting the posts out of any conditions of ground.

2. Features

2.1 MDB230 Hydraulic Guardrail Excavator Post Driver and Extractor (without the truck chassis) is composed of fixing thick steel plate, upper column, hydraulic system, PTO device, hydraulic hammer, control system, post driving and extracting equipment, extractable supporting foot. It has the characters of good mobility, quick and exact positioning, humanized design, easy operation, high efficiency after being installed onto the back of truck or trailer.

2.2 The up and down, longitudinal and transverse shift, horizontal slide and rotation of the column are realized through hydraulic system.

2.3 The hydraulic hammer is installed onto the upper column and be downward and upward along the track of the column for pile driving and extracting working by hydraulic system. When extracting guard rail posts, the extractable supporting foot is hydraulically positioned on the ground, for enhanced stability and safe pile extraction.

2.4 The control system is equipped with multiple directional control valve and centralized hydraulic control rods which makes the operation simple and convenient.

2.5 It can install piles up to 3m (9.84’) in length, but on request the machine can be supplied with extension columns which can install piles up to 3.5m (11.48’) or even 4m (13.12’) long.

2.6 The equipment does not need to turn the direction during driving and extracting the guardrail posts on both sides because of its 240° rotating device.

2.7 Its fast mobility and the capability of carrying piles and guard-rails as well as the necessary road signs, the loading capacity depends on your truck or trailer, make the truck-mounted pile driver the perfect solution for small jobs in different locations.
