Description

STILL RX50 Electric Fork Truck Workshop Manual – Ident 164530

This is the workshop manual released for the STILL RX50-10, RX50-13, RX50-15 and RX50-16 electric fork trucks, published as workshop literature 5051 / 5053 / 5054 / 5055 under Ident no. 164530 (EN). The 04.03.2005 edition was completely revised to reflect the generation 5 converter now fitted to the series, and it also documents the earlier generation 3 converter so both build phases are covered.

Rather than a driver’s booklet or a generic material-handling guide, this is the bench-level document a technician works from: it takes each assembly apart, states the tightening torques and adjustment values as they are printed, and puts it back together. Hydraulic and electrical schematics are included so that faults can be traced rather than guessed at.

What ties these chapters together is a single working method rather than a pile of facts. The manual opens with the lifting and jacking precautions the truck requires, then moves through the traction side of the machine – the asynchronous motor, its squirrel-cage rotor, sensor bearing and temperature sensor – into the power unit that carries both the motor and the drive wheel. From there it works forward through the driver’s compartment, the hydraulic steering with its orbitrol, steer motor and chain, and into the brake system with its hydraulic service brake and cable-actuated parking brake.

The electrical side is treated with the same depth. The control computer, pump regulator and drive converter each get their own treatment, including removal and installation, LED status interpretation, overtemperature behaviour, precharging of the intermediate circuit and the safe discharge of the internal backup capacitors before the converter is pulled. CAN bus wiring, the magnetic ring core used on the converter harness, fuse allocation, the forward distributor plate and rear distributor board are all set out so an electrical fault can be narrowed down systematically. The insulation test procedure is written out with the required test voltages and minimum values, and the warning that motor temperature sensors must be bypassed before testing.

On the hydraulic side, the manual covers the gear pump, priority valve, directional control valve block, lift and tilt cylinders, the lowering brake and the hose failure valves. Flow restrictor sizing for tilting is tied to rated lift height, and the pump motor speed settings are given for lift, tilt, steering and the additional hydraulic functions. Tilt cylinder resealing, mast chain adjustment with the 2 mm clearance to the coasting block, support roller replacement and the mast bearing torque are all presented as step-by-step procedures rather than summaries.

What This Workshop Manual Lets You Do

With the STILL RX50-10, RX50-13, RX50-15 and RX50-16 electric fork truck workshop manual in front of you, the jobs that normally mean calling a dealer become jobs you can schedule yourself. Removing and refitting the traction motor rotor, replacing the FAG speed sensor bearing, resealing the tilt cylinder, changing brake shoes and readjusting the parking brake, replacing the pump regulator or the drive converter, setting the steering angle sensor air gap and calibrating it through the control computer – all of these are covered with the values you need to do them correctly.

The specifications matter as much as the procedures. A wheel hub fastening screw at the wrong torque, a mast chain adjusted without the required clearance, a brake sensor left outside its valid voltage window, or a converter reinstalled without the correct heat transfer compound and screw torques will all come back as faults. This manual states those numbers as STILL published them, so the work is done to the manufacturer’s figures instead of to an estimate.

Instant PDF Delivery

The manual is delivered as a downloadable PDF immediately after checkout. There is no physical shipment and nothing to wait for – the file opens on a laptop, tablet or phone in the workshop, and any page or diagram can be printed and taken to the truck. Keep it on a shop computer for reference or on a device at the machine; either way the full 204-page document stays with you.
