Mengyang counterbalance drive motor family

What the supplier catalogue establishes

Mengyang separates counterbalance drive motors from hydraulic pump motors, steering motors and warehouse-truck drive motors in its official catalogue. The drive table names LF015, LF048, LF055 and LF043. These are grouped here as one supplier-defined functional family, rather than four new pages based only on a code column. The published table gives different power, voltage, frequency and speed values for the named variants. It establishes a catalogue identification starting point, not one universal motor specification.

Understand the identification limits

The LF048 code is not unique across the reviewed catalogue: the drive table lists 10 kW, 55 V AC and 101 Hz, while the pump table uses LF048 with 16 kW, 55 V AC and 75 Hz. Keep the product-page context and complete nameplate with the code. Do not merge these entries into an interchange claim or use matching voltage as proof that the motors perform the same job. Motor terminal voltage also does not by itself identify the truck battery or controller configuration.

Keep the supply package explicit

The official text calls thermal protection standard, whereas the table labels it optional. LF015 efficiency is printed as 0.85 in a percentage-labelled row alongside other entries expressed differently. This page does not silently correct either field or reproduce an efficiency or protection guarantee. Request a current, revision-controlled datasheet for the offered motor, including electrical type, duty definition, thermal-device provision, feedback interfaces and a dimensioned shaft and mounting drawing. The source notes customer-specific shafts, so a family photograph cannot settle coupling identity.

Questions for the proposed component

What should accompany an LF048 request?

Include the drive or pump role, full nameplate photograph, installed assembly reference, controller identity and available drawings. Ask the supplier to resolve the duplicate designation in writing before comparing an offer.

Which mechanical details need checking?

Provide the mounting pattern, pilot, shaft and coupling description, available space and connector photographs. Request the offered drawing rather than estimating dimensions or spline details from this presentation.

Does the catalogue establish truck compatibility?

No. Keep the actual truck and serial information, drive assembly and control configuration in the matching pack. A supplier must document the proposed match and any unresolved differences; this page gives no installation or commissioning procedure.

From product research to a comparable request

Prepare an identification pack with the truck model and serial information, engine or system identity, complete installed component reference and clear photographs. Include available drawings and preserve their revision identifiers. Ask shortlisted suppliers to state the exact proposed item, supplied assembly scope, condition, origin statement, matching basis and unresolved differences. Keep quantity, destination, packing, delivery and warranty questions separate from the technical identity. A catalogue picture or similar dimension does not by itself establish a suitable replacement.

Sources and evidence boundary

The company-controlled product page establishes the supplier-listed item and its published identification fields. It does not establish stock, authorization, a confirmed interchange, certification, an allowable wear limit or suitability for a particular truck. Published quality, delivery, stock, authenticity and performance claims are not independently verified or used as purchase assurances here. Obtain the current component drawing and a documented matching explanation for the actual assembly. This page gives no adjustment, repair, dismantling or return-to-service instruction.
