Hengshui Zhanhe Engineering Rubber Co., Ltd. supplies forklift fork extension and related engineering rubber products to contractors, distributors and infrastructure projects worldwide. A removable sleeve that slides over the existing fork to reach longer loads, and comes off again when the job is done.
This article explains the working principle, main types, typical applications, installation points, selection criteria, standards and frequently asked questions about forklift fork extension, and is intended for engineers, purchasers and project managers.
A removable sleeve that slides over the existing fork to reach longer loads, and comes off again when the job is done.
Working principle: The product works through elastic deformation and mechanical interlock to provide reliable sealing or load transfer.
Forklift Fork Extension is manufactured and inspected according to applicable national and industry standards. Hengshui Zhanhe Engineering Rubber Co., Ltd. carries out batch inspection before delivery, and inspection certificates together with third-party test reports (where required by the project) can be provided.
Typical standards applied to this product family include Chinese national and transportation industry standards; equivalent international standards can be referenced upon request.
A: It depends on the truck's load chart. For a 3 t truck rated at a 500 mm load centre, extending by 1000 mm gives roughly 1.0-1.2 t by equal-moment calculation, and the real figure is also limited by truck stability. Always read the manufacturer's chart and use the load plate supplied with the extension.
A: No. Forks and attachments are load-bearing safety parts and GB/T 5182 sets requirements for material, heat treatment and testing. Site welding creates a brittle heat-affected zone and a stress concentration at the root. Buy from a qualified maker with a load plate and test documents.
A: A clearance of 2-4 mm per side is normal and slight movement is fine. Visible rocking, root wear or an elongated pin hole means the fit is out of tolerance: stop using it and replace. Check the locking device before every shift.
A: Yes, and they are replaced as a pair. Unequal lengths tilt the load and overload one side. Extensions are designed and tested as pairs, so a single replacement cannot guarantee matched capacity.
Priced per pair. Cost comes from the steel section, socket size, length, cutting and welding time, the locking device and the finish. A standard Q345 extension of 1500 mm is commonly quoted at 600-1800 yuan per pair, with each extra 500 mm of length or a larger section adding to the price, and rubber-faced or anti-slip versions carrying extra process cost. For custom work, supply the fork thickness and width and the length required.
Packing: standard export packing (woven bags, pallets or wooden cases). Delivery terms: EXW, FOB, CFR, CIF or DAP as agreed. Payment terms: T/T, L/C or other terms subject to negotiation.
