A156560 Relay Gp – Lift – FFT | Doosan B15/18/20T5 Forklift

Overview

The A156560 Relay Gp – Lift – FFT is the Doosan lift relay group used across a broad range of Doosan electric counterbalance forklifts, including the B13/15/16R5, B15/18/20T5, B15/18S5 and B16/18/20X5 series. In these battery-powered trucks, the lift relay switches current to the lift pump motor, engaging the hydraulic pump whenever the operator calls for lift. When the relay’s contacts wear or burn, typical symptoms include a lift function that fails to respond, intermittent lifting, or a clicking sound with no pump engagement. Fitting the correct Doosan A156560 reference restores dependable lift performance and protects the surrounding electrical system.

Compatibility

This A156560 relay group fits the following Doosan electric forklift series:

• B13/15/16R5 series (SB1088)
• B15/18/20T5 series (SB1065) – 36V/AC motor variants
• B15/18/20T5 series (SB1066) – 48V/AC.SE motor variants
• B15/18S5 series (SB1086)
• B16/18/20X5 series (SB1067)

Whether you need the A156560 for B13/15/16R5(SB1088) or for a 48V/AC.SE B15/18/20T5 truck, this single Doosan reference covers every series listed above. Because some of these platforms were produced in more than one configuration, we recommend checking your model and serial number before ordering to confirm the relay matches your truck’s voltage and electrical layout.

Quality and Reliability

The lift circuit is one of the hardest-working circuits on an electric forklift, and its relay must handle repeated high-current switching without hesitation. The Doosan A156560 is the original reference for these trucks, built to Doosan’s specification for contact rating, terminal layout and mounting. Choosing the correct part number rather than a generic substitute helps prevent heat build-up, voltage drop and premature failure, keeping your lift hydraulics responsive shift after shift.

Installation and Maintenance Tips

• Disconnect and isolate the battery before starting work, and follow your site’s lockout/tagout procedure.
• Confirm your truck belongs to one of the compatible series above, including the correct voltage variant (36V or 48V).
• Photograph the original wiring before removal, then reconnect terminals one at a time to avoid mistakes.
• Inspect harness terminals for corrosion, pitting or heat discolouration, and clean or repair them as needed.
• Secure the relay in its original mounting position and test lift, lower and travel functions before returning the truck to service.
