The present invention relates to a laying machine for laying at least one flexible casing or tube, cable or wire including: a blade arrangement for making a trench in the ground, a consolidation and laying means being arranged behind the blade arrangement, for clearing and safe-guarding the trench from collapsing while laying at least one flexible casing or tube, cable or wire into the trench. A blade assembly comprising compartments for cooling fluid and air.
A Rotatable Cutting Chain Work Tool, A Wall Saw Arrangement Comprising Such A Work Tool, An Annular Member and A Method for Producing an Annular Member
A work tool (100) comprising: a cutting chain (110), a drive mechanism for driving the cutting chain (110), an annular member (120) arranged rotatably supported by one or more support rollers (130,140,150), wherein the annular member comprises a rim (230) adapted to support the cutting chain (110) during cutting, and a support wheel (160) arranged distanced from the annular member (120), wherein the cutting chain (110) is arranged supported on a rim segment (102) of the annular member (110) forming part of a cutting area of the tool (100) and supported on a rim segment (103) of the support wheel (160) in a direction away from the cutting area of the tool (100). An annular member and a method of producing an annular member are also disclosed.
Method and apparatus for leveling and grinding surfaces
A floor leveling apparatus and method for cutting parallel grooves in a hardened body which is configured to assist in utilizing a grinder to finish surfaces in a planar manner.
Cordless power cutter
The cordless power cutter that is lightweight and weight-balanced between a power section housing a battery pack as a power source and a cutting section including a motor in a belt-free drive system and rotatable disk blade. The weight balancing of the cordless power cutter allows the tool to remain parallel to a horizontal surface, such as the ground, without tilting, when the operator lifts and holds the tool by only a gripping or transverse portion of the lifting handle. The motor has a motor axis that is not perpendicular to the disk axis and that is rearward of the disk axis to provide a depth of cut. The weight-balance and motor positioning allows the cordless power cutter to achieve ease of handling and operation.
A Battery for Insertion in a Hand-Held Work Tool and a Hand-Held Work Tool Comprising a Battery
A battery (1800) for insertion into a battery compartment (150) of a hand-held work tool (100, 200), wherein the battery (1800) has a weight between 3-7 kg, and comprises a groove (1810) arranged on one side of the battery to mate with a corresponding supporting heel (1710) arranged on a wall of a battery compartment (150). The battery further comprises an upper ridge structure (1820) and a lower ridge structure (1830) arranged on an opposite side of the battery compared to the groove (1810), wherein the ridge structures (1820, 1830) are arranged to mate with corresponding dove-tail grooves (1720, 1730) of the battery compartment (150).
A Handheld Cut-Off Saw for Cutting Concrete and Stone, Comprising a Drive Arrangement for Driving A Circular Cutting Tool
A handheld cut-off saw (300) for cutting concrete and stone, the handheld cut-off saw comprising a drive arrangement (100, 200, 600, 800) for driving a circular cutting tool (110), the drive arrangement comprising: a belt drive portion (120) comprising a first pulley (121) and a second pulley (122), wherein the first pulley is arranged to be powered by a power source (130) and to drive the second pulley via a belt (123), wherein the second pulley (122) has a larger pitch diameter than the first pulley (121); and a gear transmission portion (140) comprising a first gearwheel (141) and a second gearwheel (142), wherein the first gearwheel (141) is co-axially connected to the second pulley (122) and radially connected to the second gearwheel (142), and wherein the second gearwheel (142) is arranged to be co-axially connected to the circular cutting tool (110).
