Turret Slewing Gearboxes & Drive Reducers for Merlo Roto Telehandlers

Failure of the turret slewing reduction gearbox on a rotating telehandler completely halts upper structure rotation, disrupting precision material handling on site. At PGA Technika, we supply complete Merlo slewing gearboxes and reduction drives (including systems compatible with Reggiana Riduttori units) engineered to restore smooth rotation and structural stability.

Our product range: Complete slewing gearboxes, housings, and shaft assemblies

We supply heavy-duty OEM-quality replacements and original Merlo parts built to handle heavy rotational loads:

Complete slewing drive assemblies – fully assembled reducers including heavy-duty housing, output shaft, and precision bearings.
Hydraulic motor-driven gearboxes – engineered for direct integration with hydraulic slewing drive motors.
Reggiana Riduttori compatible units – factory-spec gearboxes and reduction stages designed for rotating telehandlers.
Gearbox housings & drive shafts – replacement components engineered to withstand extreme torsional stress.

We supply Merlo telehandler parts specifically tailored for the Merlo Roto series.

Fast dispatch (24-48h) & downtime minimization

A broken slewing gearbox brings job site operations to a complete standstill. Standard slewing drive units are held directly in our central inventory for 24-48 hour dispatch. As a specialized Merlo parts supplier, we also handle express factory orders for rare gearbox configurations.

Accurate VIN-based Merlo parts verification

Slewing gearboxes vary across machine generations by gear reduction ratios, output shaft dimensions, and motor mounting patterns. Utilizing the official Merlo parts catalog, our technical specialists will cross-check your machine’s VIN/serial number to guarantee a 100% correct component match.
