A connecting link includes a connecting pin, a first link plate, a second link plate, and a nut member. The connecting pin includes an external thread portion and a frustum-shaped portion. The first link plate includes a hole at each of one end and an other end in a longitudinal direction. At least one of the hole at the one end and the hole at the other end of the first link plate functions as a first pin hole. The second link plate includes a hole at each of one end and an other end in a longitudinal direction. At least one of the hole at the one end and the hole at the other end of the second link plate functions as a second pin hole. The nut member is capable of being threaded to the external thread portion of the connecting pin.

A chain brace for restricting relative movement between first, second, and third serially connected links of a chain. The chain brace can include a wedge block defining a bore at least partially therethrough, first and second outer blocks, a capture frame that can include a reaction plate that can define a bore therethrough, and a tension member. The capture frame can be configured to position the outer blocks and the wedge block within the second link of the chain. The tension member can be positioned through the bore defined by the reaction plate and into the bore defined by the wedge block to apply a force on the wedge block such that the wedge block displaces the first and second outer blocks into contact with the ends of the first and third links of chain, respectively, to restrict relative movement between the first, second, and third links of the chain.

A chain connector for use with a tailgate chain linkage of a machine. The chain connector comprises a first flange, a second flange and a web. The chain connector provided with a first pair of apertures for coupling the chain connector to the machine, and a plurality of second pairs of apertures for coupling the chain connector to a chain. An effective length of the tailgate chain linkage may be adjusted by coupling the chain with a selected second pair of apertures since the plurality of second pairs of apertures are disposed at a plurality of distances from the first pair of apertures.

The invention relates to a block lock for connecting two chain ends which comprises two block lock halves which extend in the longitudinal direction and which engage with each other in a positive fit via pins and grooves and lock to form two seating openings, each one to receive a chain link. The seating openings are separated by a crossbar which extends from one of the block lock halves to the opposite block lock half, wherein the block lock halves are coupled so as to rotate about the crossbar and/or on an end of a block lock half, a pin which protrudes in the direction of the opposite block lock half, which engages laterally in one lateral seating groove formed on one end of the opposite block lock half, when carrying out a relative rotational movement of both block lock halves.

The invention relates to a securing pin (16) which, in order to secure two chain connector shackles (12, 14) of a chain connector (10) against becoming disengaged, can be inserted into an opening (28) formed by the two chain connector shackles (12, 14), comprising a base body (30) with a through-hole (32), at least one spring ring (34), at least two balls (36), and a securing member (38) inserted into the through-hole (32), wherein an annular groove (54) in which the spring ring is inserted (34) is provided in a lateral surface (59) of the base body (30), wherein the annular groove (54) is provided with two bore holes (66) which are aligned with the through-hole (32) and in which the balls (36) rest, and wherein the spring ring (34) has at least one leg (64) which extends in the longitudinal direction of the base body (30) and which bends out of shape if the securing pin (16) is inserted into the opening (28) incorrectly. The invention further relates to a chain connector (10) for connecting two chains formed from links and to a method for connecting two chains by means of a chain connector (10) and for securing the chain connector shackles (12, 14) of the chain connector (10) against becoming disengaged by means of a securing pin (16).

A breakaway chain having a breakaway connector and first and second chain portions is provided. The breakaway connector includes a first opening is defined between a first wall portion and a second wall portion spaced away from the first wall portion. A first flexible gripping member extends from the first wall portion towards the second wall portion. A second opening is defined between a third wall portion and a fourth wall portion spaced away from the third wall portion. A second flexible gripping member extends from the third wall portion towards the fourth wall portion. The first chain portion has a first chain link. The first chain link inserts into the first opening and engages the first flexible gripping member. The second chain portion has a second chain link. The second chain link inserts into the first opening and engages the second flexible gripping member.

A block lock for connecting two chain ends, wherein, in the locked state, the block lock has two oppositely located block-lock halves which extend in the longitudinal direction, interengage in a form-fitting manner via a respective stub and stub socket and lock to form at least one accommodating opening, preferably two accommodating openings, for accommodating a chain link. The block-lock halves interengage in a comb-like manner at their ends.
