Definitions

  • a pair of rollers are positioned above a pulley over which a hose and chain are trained so as to keep the hose between the side bars of the chain as the hoseand chain pass over the pulley.
  • FIG. 1 is a side view of the lift trubk in which the present invention is incorporated;
  • FIG. 2 is an enlarged view taken along the lines IIII in FIG. 1;
  • FIG. 3 is a side view of the structure shown in FIG. 2.
  • the motorized lift truck 1 1 includes a pair of rear steer wheels 12, a pair of front drive wheels 13, an operator station 14 and a mast 16 pivotally mounted on the front end of the lift truck 11 by means, not shown, for limited tilting movement.
  • the mast 16 includes stationary uprights l7 and a pair of extensible uprights 18.
  • a carriage 21 is mounted on the extensible uprights 18 for vertical, reciprocable movement relative thereto in a conventional manner.
  • the carriage 21, with its load engaging forks 22, is raised and lowered by a pair of link type chains 23 which are connected at one end to the cylinder 26 of a lift jack 27, one chain being connected at an attaching point 28.
  • the other corresponding ends of the chains are connected to the rear of the carriage 21, one chain being shown attached to a bracket 29.
  • the lift jack 27 includes an extensible component in the form of a piston 2 31m which a pair of pulleys 32 are pivotally mounted on a block 34 on the top of the piston component 31 of the single acting lift jack 27.
  • a pair of hydraulic hoses 41 are carried on the chains 23 in a position intermediate the side bars 43 thereof. Since the side bars extend radially outwardly a substantial distance from the connection formed by a pin 46 and a bushing 47 of each link of the chain, the hoses will tend to stay in their nested position between the side bars 43.
  • a pair of rollers 51 are disposed above the pulleys 32 and the hoses 41 so to gently engage the hoses should they have any tendency to disengage from their nested position between the side bars 43 of the chains 23.
  • the rollers 51 are made of suitable material so as to possess good wearing qualities and should be smooth so as not to injure the flexible hoses.
  • rollers 51 are pivotally secured to a U- shaped bracket 53 and have radially outwardly extending flanges 56, 57, on opposite lateral sides of an annular recess 58, which aid in maintaining the hoses 41 in their desired position between the side bars 43.
  • the bracket 53 is secured to the block 34 on the piston 31 by a pair of cap screws 59.
  • a single guide roller might be employed for each hose, it is prefered to provide two guide rollers for each hose so as to give greater assurance of maintaining the hose in its desired position on the chain.
  • this hose guide arrangement does not take up any additional lateral space in the lift truck mast, and thus avoids any interference with the visibility of the driver that might otherwise occur should the hose guide means be positioned as extensions of the pulleys.
  • the hoses are held on the chain in a positive and extremely economical manner.
  • a lift truck having a carriage reciprocably mounted for raising and lowering on a pair of uprights by an extensible element of a lift jack, the combination comprising:
  • a lift chain connected to said carriage and passing over said pulley, said chain including interconnected links with spaced side bars,
  • a guide roller pivotally mounted on'said extensible element above said pulley and engageable with said hose to maintain the latter in its position between said side bars as said chain and hose pass together over said pulley.
