Industrial trolleys and carts ? Warehouse handling equipment ? Material transport systems ? Workshop equipment ? Retail display units ? Food service equipment ? Medical and healthcare carts ? Storage and shelving units Installation Guidelines Mounting Instructions: Position the top plate on the equipment base ensuring proper alignment Mark the four mounting hole positions using the 80mm x 60mm hole pattern Drill holes suitable for 10mm bolts (11mm hole diameter accommodates standard M10 fixings) Secure the castor using appropriate bolts, washers, and lock nuts Ensure all fixings are tightened to manufacturer specifications Test the directional brake function before placing equipment into service Note: Always distribute load evenly across all castors and ensure total equipment weight does not exceed the combined load capacity. Frequently Asked Questions What is the difference between a directional brake and a total lock brake? A directional brake locks only the swivel function of the castor, allowing the wheel to continue rolling forwards and backwards. This is ideal for loading and unloading operations where you need stability but still require some movement. A total lock brake would lock both the swivel and the wheel rotation completely. Can this castor be used on uneven surfaces? This castor is designed primarily for smooth, flat surfaces such as concrete, tiled floors, and sealed surfaces. The solid nylon wheel performs best on even ground. For rough or uneven terrain, a pneumatic or rubber wheel castor would be more suitable. What is the maximum load I can place on a set of four castors? Each castor has a load capacity of 140kg, giving a total capacity of 420kg when using four castors. However, it is recommended to operate at approximately 80% of maximum capacity for optimal performance and longevity, which would be around 336kg for a four-castor configuration. Will the white nylon wheel mark my floors? White nylon wheels are designed to be non-marking on most floor surfaces, making them suitable for clean environments, retail spaces, and areas where floor appearance is important. However, floor marking can occasionally occur if debris becomes embedded in the wheel or if excessive loads are applied. How do I maintain these castors for optimal performance? Regular maintenance includes inspecting wheels for debris or damage, checking that all mounting bolts remain tight, testing the brake mechanism for proper function, and periodically cleaning the swivel bearing area. Lubrication of the ball journal bearing every 6-12 months will ensure smooth swivel operation. What size bolts do I need for installation? The 11mm mounting holes are designed to accommodate M10 bolts (10mm diameter). We recommend using M10 bolts with appropriate washers and lock nuts to ensure secure fixing. Bolt length will depend on your equipment base thickness. Can these castors be used in cold storage or outdoor environments? These castors have an operating temperature range of -20°C to ?°C, making them suitable for cold storage applications. However, for permanent outdoor use, consider that the zinc-plated steel finish provides moderate corrosion resistance. For harsh outdoor or marine environments, stainless steel castors would be more appropriate. Should I use all swivel castors or a combination of swivel and fixed castors? For maximum manoeuvrability, use four swivel castors. For improved straight-line tracking and stability, use two swivel castors at one end and two fixed castors at the opposite end. The directional brake feature on these castors provides additional control when using an all-swivel configuration. Premium mobility solutions for industrial and commercial applications
