Accessories and Spare Parts for LIS® Hydraulic Breakers

Accessories and spare parts for LIS® hydraulic breakers

Accessories for LIS® hydraulic breakers include tools, wear parts, sealing and connecting elements as well as technical spare components for maintenance, repair and service work. In this category, you will find accessories and spare parts suitable for defined LIS® hydraulic breaker model series. Selection should always be based on breaker model, model series, item number, existing component and technical version.

This category is focused on LIS® hydraulic breakers. The listed parts are therefore not intended as universal spare parts for hydraulic breakers from any manufacturer. For clear identification, the model designation, component position, tool diameter, existing item number and, where applicable, the technical documentation of the hydraulic breaker should be checked.

Typical product groups in hydraulic breaker accessories

Depending on the LIS® hydraulic breaker model series, the accessories range may include different components. Typical examples include chisels, bushings, pins, spring pins, through-bolts, seal kits, seal holders, adapters, grease nipples, valves, pistons, cylinders, front heads, back heads, covers, plugs, screws and maintenance accessories.

Selecting chisels for hydraulic breakers correctly

Hydraulic breaker chisels are selected according to breaker model, tool diameter, shank size, tool shape and application material. Pointed chisels are suitable for concentrated penetration into concrete, asphalt or natural stone. Flat chisels support cutting or directionally guided work. Blunt tools work more through impact effect and are used on hard, brittle material.

An incorrectly selected or worn chisel can alter the impact direction and place additional load on bushings, pins, front head and piston. For this reason, tool holder, wear pattern, chisel shank and lubrication condition should be checked regularly. During tool changes, it should also be checked whether retaining elements, pins and bushings match the relevant LIS® model series.

Wear parts and components for maintenance and repair

Hydraulic breakers operate under high mechanical and hydraulic load. Typical inspection and wear areas include chisels, bushings, pins, seals, lubrication points, hoses, front head, back head and components of the impact mechanism. The exact spare part selection depends on breaker size, operating hours, application material, maintenance condition and existing component version.

Seal kits, valves, pistons, cylinders and housing components should only be selected to match the relevant LIS® hydraulic breaker model series. Even small deviations in component version, seal design or installation position can affect the function of the hydraulic breaker. For technical components, identification by model designation, item number or existing spare parts documentation is recommended.

Parts identification by LIS® model series and breaker model

Many accessories and spare parts are model-series dependent. A pin, bushing, seal kit or chisel for a compact breaker model is not automatically compatible with larger hydraulic breakers. The decisive factors are the specific LIS® model series, the technical version of the breaker and the respective component position.

For identification, existing information on the hydraulic breaker, the item number of the spare part, the previously installed component and the technical drawing or operating manual should be checked. If a component cannot be clearly identified, the selection should be technically verified before ordering.

Maintenance, lubrication and operational reliability

Regular maintenance supports operational reliability and helps to avoid consequential damage caused by wear, dry running or incorrect operation. Chisels and bushings must be lubricated according to the operating manual. Grease nipples, pins, retaining elements, seals and visible wear areas should be checked regularly.

Hydraulic oil, oil temperature, oil filtration, return pressure and hose connections also influence the operating condition and wear behaviour of the breaker, tools and spare parts. Blank firing, levering with the chisel, side loading, using the hydraulic breaker to transport loads and prolonged hammering on the same point should be avoided.

Complete hydraulic breakers and technical support

If you need a complete hydraulic breaker rather than a spare part, the matching categories are available by carrier weight: hydraulic breakers for mini excavators 0.8–7.0 t, hydraulic breakers for excavators 8.0–35.0 t and hydraulic breakers for excavators 40.0–75.0 t.

For installation, maintenance and safety-related information, the user manuals for LIS® hydraulic breakers are available for download. LIS® attachments are subject to the LIS® warranty terms and conditions. Wear parts, tools and components specified in the warranty terms must be considered separately.

Spare part not clearly identified? Our technical team will assist you in selecting suitable accessories and spare parts for LIS® hydraulic breakers. Please have the breaker model, item number, component designation or a photo of the existing component available where possible. Technical support.

Note: Compatibility information refers to LIS® hydraulic breakers and is used for technical identification. For hydraulic breakers from other manufacturers, compatibility must be checked separately before ordering.
