Compact, rubber-tracked loaders
The Caterpillar 267 and 277 multiterrain loaders are the first of a new class of compact, rubber-tracked machines de signed for versatility, flotation, traction, and stability.
Loaders feature a suspended track under carriage that allows the machines to work in a range of applications and terrain conditions. They can be handy in soft, wet underfoot conditions and on sloped terrain.
The loaders combine the upper portion of the Caterpillar 236 and 246 skid steer loaders with an updated Maximum Trac tion and Support System undercarriage.
The 267 has an operating capacity, as defined by SAE as 35% of tipping load, of 2,030 lb, and the 277 operating capacity is 2,065 lb.
Operating weight of the 267 is 9,088 lb, and the 277 has an operating weight of 9,126 lb-ground pressure 3.1 psi for the 267 and the 277.
A naturally aspirated Cat 3034 diesel engine powers the 267 with net output of 59 hp. A turbocharged 3034 generates net power of 74 hp in the 277.
The closed-loop, high-output hydrostatic drive system in each loader features an exclusive antistall system. Dual, closed-loop, axial piston pumps are driven directly off the engine. The pumps power two fixed displacement motors.
The pilot-hydraulic joystick controls help reduce operator effort and allow precise movement of machine and work tools. Hand and foot throttles enable the operator to use what suits the task. The cab design offers viewing area and site lines to the work area, and entry and exit are easy, as the two tilt cylinders are at the sides of the machine.

Process automation control family expanded
The newest member of the Control Wave family of process automation controllers-the ControlWave LP-comes in an 81/2 by 121/2 in. RTU style package. It utilizes a high performance 486 based CPU design to meet SCADA applications.
The new unit offers rugged, isolated input-output for long-term reliability, temperature operation from -40° to +70° C. for remote sites, and low power consumption for solar applications. Additionally ControlWave has been designed to meet CE, Class I, Div. 2, and international hazardous location requirements.
The local I/O provides 16 DI, 8 DO, 8AI, 4 HSC, and up to 8 optional AO. Also, a variety of remote Ethernet I/O modules promises a cost-effective method for I/O expansion access throughout the plant or even within an enclosure.
ControlWave LP has five serial communication ports and one 10 Mb Ethernet I/P port for flexibility. The new LP facilitates communication with other devices through networks such as TCP/IP open Modbus, and serial Modbus. For open access to most HMI products, the firm offers a flexible, easy to implement OPC server. And ControlWave LP comes with BSAP protocol as a standard feature.
The ControlWave Designer programming software supports all five IEC 61131-3 programming languages and is extended with a library of process control function blocks. With this combination, ControlWave LP allows the use of a single controller for logic, process control functions, measurement, calculations, and data storage. These capabilities are further enhanced with time stamped alarming, audit, and historical archive storage within the RTU.
