Wacker BH23 Impact Tamper Ballast Tamping Machine

Wacker BH23 Impact Tamper Ballast Tamping Machine

I. Product Overview | Wacker BH23 Impact Tamper

The Wacker BH23 Impact Tamper is a professional portable gasoline-powered impact tamper, widely recognized and applied in railway track maintenance engineering. It features compact structure, high impact efficiency, stable performance and easy operation, which is the ideal professional equipment for railway ballast tamping and compacted ballast breaking operations.

II. Technical Parameters

III. Working Principle

Power from the gasoline engine is transmitted to the reduction gearbox through the driven plate. After gear reduction, the crankshaft gear drives the connecting rod, piston and inner cylinder to perform high-frequency vertical reciprocating movement, continuously impacting the chisel assembly.The powerful impact energy is further transmitted to the pick leg, which delivers high-frequency & high-energy impact force to working materials. This mechanism efficiently realizes ballast tamping and compacted material breaking operations.

IV. Main Application

Equipped with tamping pick leg: Professional tamping construction for railway tracks, turnouts and ballast bed maintenance

Equipped with breaking pick leg: Breaking operation for hardened & compacted railway ballast bed

VI. Operating Instructions for Wacker Tamper

1. Pr-operation Preparation

(1) Inspect and fasten all bolts and threaded connections of the Wacker tamper thoroughly. Stop operation immediately and arrange maintenance once any looseness, damage or abnormality is detected.

(2) Prepare premixed fuel strictly according to 25:1 gasoline-oil ratio with a professional mixing jug, shake evenly and fill into the fuel tank.

(3) Check the oil level of the internal impact mechanism, replenish SAE15W-40 diesel oil when oil is insufficient.

(4) Inspect the wear condition of the tamping pick bit; replace it immediately if worn beyond the service limit.

(5) Perform regular grease lubrication maintenance on the whole impact mechanism.

2. Startup & Working Operation

(1) Confirm the Wacker tamper is in complete good condition before startup. Distinguish cold start and hot start modes, follow panel instructions step by step. Always operate the hand fuel pump, choke valve and decompression valve correctly.

(2) Fully open the choke valve for hot start, to avoid spark plug wetting caused by over-rich fuel mixture. Press the decompression valve before every startup.

(3) Hold the throttle handle with one hand, pull the starter rope rapidly with the other hand. After engine ignition, release the starter handle slowly and open the choke valve completely.

(4) Keep the engine running at idle speed for 2~3 minutes after startup, to fully lubricate all internal engine parts.

(5) Hold the tamper handle, fully open the throttle and press down the machine for tamping work. Do not apply excessive force or press to the bottom; maintain stable pressure during tamping. Do not twist the Wacker tamper left and right during operation, to prevent damage to the damping spring.

(6) Release the throttle and lift the handle when changing working positions.

3. Shutdown Procedure

(1) Turn the throttle to the minimum position, push the power off switch outward to shut down the engine.

(2) Place the Wacker tamper flat on the ground during long-term idle or non-use, to avoid collision damage to the gasoline engine.

(3) Drain all gasoline from the fuel tank if the machine is shut down for more than 2 weeks. Restart the engine and run it until all residual fuel in the carburetor is completely consumed before final shutdown.
