Document 57.4402.9200 - 1 st Edition 10/2006 INDEX i TELELIFT 3713 SX INTRODUCTION INTRODUCTION Important Read, understand and obey the safety rules and operating instructions in the Telelift 71 SX Operator's Handbook before attempting any maintenance or repair procedure. This manual provides the machine owner and user with detailed information on the scheduled maintenance. It also provided qualifed service technicians with infromation on troubleshooting and repair procedures. Basic mechanical, hydraulic and electrical skills are required to perform most procedures. However, several procedures require specialized skills, as well as specifc tools and equipment. In these instances, we strongly recommend letting service and repair the machine at an authorized TEREXLIFT service center.

Document 57.4402.9200 - 1 st Edition 10/2006 INDEX TELELIFT 3713 SX INTRODUCTION ii DESCRIPTION OF THE MACHINE OPERATION The source of mechanical energy of this machine is a naturally aspirated diesel engine (1) model Perkins 1104C-44 with direct injection, water cooling, 4 cylinders, 63.5 kW power (86 HP) at 2400 rev/min., max torque of 302 Nm at 1400 rev./min. or, in alternative, a turbo.- compressed diesel engine model Perkins 1104C/44T, with direct injection, water cooling, 4 cylinders, 74.4 kW power (101 HP) at 2400 rev./min., max. torque of 412 Nm at 1400 rev./min. On the fywheel side of the engine, and connected to this engine by a Technodrive coupler complete with elastic joint and with a 1-to-1 ratio, there is Bosch- Rexroth closed-loop pump for hydrostatic drives, model A4VG71 () with adjustment valve of DA type. The max displacement of this swashplate pump is 71 cm 3 /rev. and the max calibration pressure is 420 bar. This pump is used to supply hydraulic power under form of pressure and fow rate which is then used for moving the machine. On the through-shaft of such drive pump there is a Casappa open-loop gear pump (with fxed displacement) (4) with priority valve integrated in the housing (1). The displacement of this pump is 43 cm 3 /rev. Its function is to provide hydraulic power, under form of pressure and fow rate, to the steering circuit of the machine (priority side) and to the circuit for the telescopic boom movements (secondary side). The assembly of the two pumps involves they have a rotation velocity equal to the speed of the diesel engine. A third Casappa open-loop gear pump (with fxed displacement) (5) with a displacement of 20 cm 3 /rev., is installed on the PTO of the engine located to the distribution side. This pump feeds the servo-assisted braking system (18) and the unused oil fow is delivered to the hydraulic geared motor Casappa (8) with a displacement of 20 cm 3 for the operation of the cooling fan mounted on the heat exchanger (9). Inside the motor housing, an anti-cavitation valve and a pressure limiting valve with bypass function set at 140 bar, are installed. The suction lines of the open-loop pumps (5) and (4) are protected by an immersed flter (7), placed inside the hydraulic fuid tank (11) whose capacity is 120 litres. Just upstream of the connection with the two suction lines mentioned above, there is a gate valve with ball valve which lets you cut out the hydraulic oil tank in order to perform maintenance interventions on the machine's hydraulic system. On the contrary, the drive pump () is protected by a cartridge flter (6), installed on the suction line of the booster pump. This pump is an integral part of the drive pump. The one-way valve (1) set at 2.5 bar protects the pump housing against high pressures and guarantees a certain circulation of the drain oil to the hydrostatic motor reducing, in this way, the temperature. From port “G” of the drive pump () low- pressure oil is taken (25-30 bar) and used for the anti- Courtesy of Crane.Market
